CHAPTER I:
IMPORTANCE OF THE LITURGY OF THE HOURS OR DIVINE OFFICE IN THE LIFE OF THE CHURCH  

1. Public and common prayer by the people of God is rightly considered to be 
among the primary duties of the Church. From the very beginning those who were 
baptized "devoted themselves to the teaching of the apostles and to the 
community, to the breaking of the bread, and to prayer" (Acts 2:42). The Acts of 
the Apostles give frequent testimony to the fact that the Christian community 
prayed with one accord. [1]  

The witness of the early Church teaches us that individual Christians devoted 
themselves to prayer at fixed times. Then, in different places, it soon became 
the established practice to assign special times for common prayer, for example, 
the last hour of the day when evening draws on and the lamp is lighted, or the 
first hour when night draws to a close with the rising of the sun.  

In the course of time other hours came to be sanctified by prayer in common. 
These were seen by the Fathers as foreshadowed in the Acts of the Apostles. 
There we read of the disciples gathered together at the third hour. [2] The 
prince of the apostles "went up on the housetop to pray, about the sixth hour" 
(10:9); "Peter and John were going up to the temple at the hour of prayer, the 
ninth hour" (3:1); "about midnight Paul and Silas were praying and singing hymns 
to God" (16:25).  

2. Such prayer in common gradually took the form of a set cycle of hours. This 
liturgy of the hours or divine office, enriched by readings, is principally a 
prayer of praise and petition. Indeed, it is the prayer of the Church with 
Christ and to Christ.

I. PRAYER OF CHRIST
CHRIST THE INTERCESSOR WITH THE FATHER  

3. When the Word, proceeding from the Father as the splendor of his glory, came 
to give us all a share in God's life, "Christ Jesus, High Priest of the new and 
eternal covenant, taking human nature, introduced into this earthly exile the 
hymn of praise that is sung throughout all ages in the halls of heaven." [3] 
From then on in Christ's heart the praise of God assumes a human sound in words 
of adoration, expiation, and intercession, presented to the Father by the Head 
of the new humanity, the Mediator between God and his people, in the name of all 
and for the good of all.  

4. In his goodness the Son of God, who is one with his Father (see Jn 10:30) and 
who on entering the world said: "Here I am! I come, God, to do your will" (Heb 
10:9; see Jn 6:38), has left us the lesson of his own prayer. The Gospels many 
times show us Christ at prayer: when his mission is revealed by the Father; [4] 
before he calls the apostles; [5] when he blesses God at the multiplication of 
the loaves; [6] when he is transfigured on the mountain; [7] when he heals the 
deaf-mute; [8] when he raises Lazarus; [9] before he asks for Peter's confession 
of faith; [10] when he teaches the disciples how to pray; [11]when the disciples 
return from their mission; [12] when he blesses the little children; [13] when 
he prays for Peter. [14]  

The work of each day was closely bound up with his prayer, indeed flowed out 
from it: he would retire into the desert or into the hills to pray, [15] rise 
very early [16] or spend the night up to the fourth watch [17] in prayer to God. 
[18]  

We are right in thinking that he took part both in public prayers: in the 
synagogues, which he entered on the Sabbath "as his custom was;" [19] in the 
temple, which he called a house of prayer; [20] and in the private prayers that 
for devout Israelites were a daily practice. He used the traditional blessings 
of God at meals, as is expressly mentioned in connection with the multiplication 
of the loaves, [21] the last supper [22] and the meal at Emmaus. [23] He also 
joined with the disciples in a hymn of praise. [24]  

To the very end of his life, as his passion was approaching, [25] at the last 
supper, [26] in the agony in the garden, [27] and on the cross, [28] the divine 
teacher showed that prayer was the soul of his Messianic ministry and paschal 
death. "In the days of his life on earth he offered up prayers and entreaties 
with loud cries and tears to the one who could deliver him from death and 
because of his reverence his prayer was heard" (Heb 5:7). By a single offering 
on the altar of the cross "he has made perfect forever those who are being 
sanctified" (Heb 10-14). Raised from the dead, he lives for ever, making 
intercession for us. [29]

II. PRAYER OF THE CHURCH   
COMMANDMENT TO PRAY  

5. Jesus has commanded us to do as he did. On many occasions he said: "Pray," 
"ask," "seek" [30] "in my name." [31] He taught us how to pray in what is known 
as the Lord's Prayer. [32] He taught us that prayer is necessary, [33] that it 
should be humble, [34] watchful, [35] persevering, confident in the Father's 
goodness, [36] single-minded, and in conformity with God's nature. [37]  

Here and there in their letters the apostles have handed on to us many prayers, 
particularly of praise and thanks. They instruct us on prayer in the Holy 
Spirit, [38] through Christ, [39] offered to God, [40] as to its persistence and 
constancy, [41] its power to sanctify, [42] and on prayer of praise, [43] 
thanks, [44] petition, [45] and intercession for all. [46]  

CHRIST'S PRAYER CONTINUED BY THE CHURCH  

6. Since we are entirely dependent on God, we must acknowledge and express this 
sovereignty of the Creator, as the devout people of every age have done by means 
of prayer.  

Prayer directed to God must be linked with Christ, the Lord of all, the one 
Mediator [47] through whom alone we have access to God.[48] He unites to himself 
the whole human community [49] in such a way that there is an intimate bond 
between the prayer of Christ and the prayer of all humanity. In Christ and in 
Christ alone human worship of God receives its redemptive value and attains its 
goal.  

7. There is a special and very close bond between Christ and those whom he makes
members of his Body, the Church, through the sacrament of rebirth. Thus, from 
the Head all the riches belonging to the Son flow throughout the whole Body: the 
communication of the Spirit, the truth, the life, and the participation in the 
divine sonship that Christ manifested in all his prayer when he dwelt among us.  

Christ's priesthood is also shared by the whole Body of the Church, so that the 
baptized are consecrated as a spiritual temple and holy priesthood through the 
rebirth of baptism and the anointing by the Holy Spirit [50] and are empowered 
to offer the worship of the New Covenant, a worship that derives not from our 
own powers but from Christ's merit and gift.  

"God could give us no greater gift than to establish as our Head the Word 
through whom he created all things and to unite us to that Head as members. The 
results are many The Head is Son of God and Son of Man, one as God with the 
Father and one as man with us. When we speak in prayer to the Father, we do not 
separate the Son from him and when the Son's Body prays it does not separate 
itself from its Head. It is the one Savior of his Body, the Lord Christ Jesus, 
who prays for us and in us and who is prayed to by us. He prays for us as our 
priest, in us as our Head; he is prayed to by us as our God. Recognize therefore 
our own voice in him and his voice in us." [51]  

The excellence of Christian prayer lies in its sharing in the reverent love of 
the only-begotten Son for the Father and in the prayer that the Son put into 
words in his earthly life and that still continues without ceasing in the name 
of the whole human race and for its salvation, throughout the universal Church 
and in all its members.  

ACTION OF THE HOLY SPIRIT  

8. The unity of the Church at prayer is brought about by the Holy Spirit, who is
the same in Christ, [52] in the whole Church, and in every baptized person. It 
is this Spirit who "helps us in our weakness" and "intercedes for us with 
longings too deep for words" (Rom 8:26). As the Spirit of the Son, he gives us 
"the spirit of adopted children, by which we cry out: Abba, Father" (Rom 8:15; 
see Gal 4:6; 1 Cor 12:3; Eph 5:18; Jude 20). There can be therefore no Christian 
prayer without the action of the Holy Spirit, who unites the whole Church and 
leads it through the Son to the Father.  

COMMUNITY CHARACTER OF PRAYER  

9. It follows that the example and precept of our Lord and the apostles in 
regard to constant and persevering prayer are not to be seen as a purely legal 
regulation. They belong to the very essence of the Church itself, which is a 
community and which in prayer must express its nature as a community. Hence, 
when the community of believers is first mentioned in the Acts of the Apostles, 
it is seen as a community gathered together at prayer "with the women and Mary, 
the mother of Jesus, and his brothers" (Acts 1:14). "There was one heart and 
soul in the company of those who believed" (Acts 4:32). Their oneness in spirit 
was founded on the word of God, on the communion of charity, on prayer, and on
the eucharist. [53]  

Though prayer in private and in seclusion [54] is always necessary and to be 
encouraged [55] and is practiced by the members of the Church through Christ in 
the Holy Spirit, there is a special excellence in the prayer of the community. 
Christ himself has said: "Where two or three are gathered together in my name, I 
am there in their midst" (Mt 18:20).

III. LITURGY OF THE HOURS 
CONSECRATION OF TIME  

10. Christ taught us: "You must pray at all times and not lose heart" (Lk 18:1). 
The Church has been faithful in obeying this instruction; it never ceases to 
offer prayer and makes this exhortation its own: "Through him (Jesus) let us 
offer to God an unceasing sacrifice of praise" (Heb 15:15). The Church fulfills 
this precept not only by celebrating the eucharist but in other ways also, 
especially through the liturgy of the hours. By ancient Christian tradition what 
distinguishes the liturgy of the hours from other liturgical services is that it 
consecrates to God the whole cycle of the day and the night. [56]  

11. The purpose of the liturgy of the hours is to sanctify the day and the whole 
range of human activity. Therefore its structure has been revised in such a way 
as to make each hour once more correspond as nearly as possible to natural time 
and to take account of the circumstances of life today. [57]  

Hence, "that the day may be truly sanctified and the hours themselves recited 
with spiritual advantage, it is best that each of them be prayed at a time most 
closely corresponding to the true time of each canonical hour." [58]  

LITURGY OF THE HOURS AND THE EUCHARIST  

12. To the different hours of the day the liturgy of the hours extends [59] the 
praise and thanksgiving, the memorial of the mysteries of salvation, the 
petitions and the foretaste of heavenly glory that are present in the 
eucharistic mystery, "the center and high point in the whole life of the 
Christian community." [60]  

The liturgy of the hours is in turn an excellent preparation for the celebration 
of the eucharist itself, for it inspires and deepens in a fitting way the 
dispositions necessary for the fruitful celebration of the eucharist: faith, 
hope, love, devotion, and the spirit of self-denial.  

PRIESTHOOD OF CHRIST IN THE LITURGY OF THE HOURS  

13. In the Holy Spirit Christ carries out through the Church "the task of 
redeeming humanity and giving perfect glory to God," [61] not only when the 
eucharist is celebrated and the sacraments administered but also in other ways 
and especially when the liturgy of the hours is celebrated. [62] There Christ 
himself is present - in the gathered community, in the proclamation of God's 
word, "in the prayer and song of the Church." [63]  

SANCTIFICATION OF GOD'S PEOPLE  

14. Our sanctification is accomplished [64] and worship is offered to God in the 
liturgy of the hours in such a way that an exchange or dialogue is set up 
between God and us, in which "God is speaking to his people ... and his people 
are responding to him by both song and prayer." [65]  

Those taking part in the liturgy of the hours have access to holiness of the 
richest kind through the life-giving word of God, which in this liturgy receives 
great emphasis. Thus its readings are drawn from sacred Scripture, God's words 
in the psalms are sung in his presence, and the intercessions, prayers, and 
hymns are inspired by Scripture and steeped in its spirit. [66]  

Hence, not only when those things are read "that are written for our 
instruction" (Rom 15:4), but also when the Church prays or sings, faith is 
deepened for those who take part and their minds are lifted up to God, in order 
to offer him their worship as intelligent beings and to receive his grace more 
plentifully. [67]  

PRAISING GOD WITH THE CHURCH IN HEAVEN  

15. In the liturgy of the hours the Church exercises the priestly office of its 
Head and offers to God "without ceasing" [68] a sacrifice of praise, that is, a 
tribute of lips acknowledging his name. [69] This prayer is "the voice of a 
bride addressing her bridegroom; it is the very prayer that Christ himself, 
together with his Body, addresses to the Father." [70] "All who render this 
service are not only fulfilling a duty of the Church, but also are sharing in 
the greatest honor of Christ's Bride for by offering these praises to God they 
are standing before God's throne in the name of the Church, their Mother." [71]  

16. When the Church offers praise to God in the liturgy of the hours, it unites 
itself with that hymn of praise sung throughout all ages in the halls of heaven; 
[72] it also receives a foretaste of the song of praise in heaven, described by 
John in the Book of Revelation, the song sung continually before the throne of 
God and of the Lamb. Our close union with the Church in heaven is given 
effective voice "when we all, from every tribe and tongue and people and nation 
redeemed by Christ's blood (see Rv 5:9) and gathered together into the one 
Church, glorify the triune God with one hymn of praise." [73]  

The prophets came almost to a vision of this liturgy of heaven as the victory of 
a day without night, of a light without darkness: "The sun will no more be your 
light by day, and the brightness of the moon will not shine upon you, but the 
Lord will be your everlasting light" (Is 60:19; see Rv 21:23 and 25). "There
will be a single day, known to the Lord, not day and night, and at evening there 
will be light" (Zech 14:7). Already "the end of the ages has come upon us (see I 
Cor 10:11) and the renewal of the world has been irrevocably established and in 
a true sense is being anticipated in this world." [74] By faith we too are 
taught the meaning of our temporal life, so that we look forward with all 
creation to the revealing of God's children. [75] In the liturgy of the hours we 
proclaim this faith, we express and nourish this hope, we share in some degree 
the joy of everlasting praise and of that day that knows no setting.  

PETITION AND INTERCESSION  

17. But besides the praise of God, the Church in the liturgy of the hours 
expresses the prayers and desires of all the faithful; indeed, it prays to 
Christ, and through him to the Father, for the salvation of the whole world. 
[76] The Church's voice is not just its own; it is also Christ's voice, since 
its prayers are offered in Christ's name, that is, "through our Lord Jesus 
Christ," and so the Church continues to offer the prayer and petition that 
Christ poured out in the days of his earthly life [77] and that have therefore a 
unique effectiveness. The ecclesial community thus exercises a truly maternal 
function in bringing souls to Christ, not only by charity, good example, and
works of penance but also by prayer. [78]  

The concern with prayer involves those especially who have been called by a 
special mandate to carry out the liturgy of the hours: bishops and priests as 
they pray in virtue of their office for their own people and for the whole 
people of God; [79] other sacred ministers, and also religious. [80]  

18. Those then who take part in the liturgy of the hours bring growth to God's 
people in a hidden but fruitful apostolate, [81] for the work of the apostolate 
is directed to this end, "that all who are made children of God by faith and 
baptism should come together to praise God in the midst of this Church, to take 
part in the sacrifice, and to eat the Lord's Supper." [82]  

Thus by their lives the faithful show forth and reveal to others "the mystery of 
Christ and the real nature of the true Church. It is of the essence of the 
Church to be visible yet endowed with invisible resources, eager to act yet 
intent on contemplation, present in this world yet not at home in it." [83]  

In their turn the readings and prayers of the liturgy of the hours form a 
wellspring of the Christian life: the table of sacred Scripture and the writings 
of the saints nurture its life and prayers strengthen it. Only the Lord, without 
whom we can do nothing, [84] can, in response to our request, give power and 
increase to what we do, [85] so that we may be built up each day in the Spirit 
into the temple of God, [86] to the measure of Christ's fullness, [87] and 
receive greater strength also to bring the good news of Christ to those outside. 
[88]  

HARMONY OF MIND AND VOICE  

19. Mind and voice must be in harmony in a celebration that is worthy, 
attentive, and devout, if this prayer is to be made their own by those taking 
part and to be a source of devotion, a means of gaining God's manifold grace, a 
deepening of personal prayer, and an incentive to the work of the apostolate. 
[89] All should be intent on cooperating with God's grace, so as not to receive 
it in vain. Seeking Christ, penetrating ever more deeply into his mystery 
through prayer [90] they should offer praise and petition to God with the same 
mind and heart as the divine Redeemer when he prayed.

IV. PARTICIPANTS IN THE LITURGY OF THE HOURS

A. CELEBRATION IN COMMON  

20. The liturgy of the hours, like other liturgical services, is not a private
matter but belongs to the whole Body of the Church, whose life it both expresses 
and affects. [91] This liturgy stands out most strikingly as an ecclesial 
celebration when, through the bishop surrounded by his priests and ministers, 
[92] the local Church celebrates it. For "in the local Church the one, holy, 
catholic, and apostolic Church is truly present and at work." [93] Such a 
celebration is therefore most earnestly recommended. When, in the absence of the 
bishop, a chapter of canons or other priests celebrate the liturgy of the hours, 
they should always respect the true time of day and, as far as possible, the 
people should take part. The same is to be said of collegiate chapters.  

21. Wherever possible, other groups of the faithful should celebrate the liturgy 
of the hours communally in church. This especially applies to parishes - the 
cells of the diocese, established under their pastors, taking the place of the 
bishop; they "represent in some degree the visible Church established throughout 
the world." [94]  

22. Hence, when the people are invited to the liturgy of the hours and come 
together in unity of heart and voice, they show forth the Church in its 
celebration of the mystery of Christ. [95]  

23. Those in holy orders or with a special canonical mission [96] have the 
responsibility of initiating and directing the prayer of the community; "they 
should expend every effort so that those entrusted to their care may become of 
one mind in prayer." [97] They must therefore see to it that the people are 
invited, and prepared by suitable instruction, to celebrate the principal hours 
in common, especially on Sundays and holydays. [98] They should teach the people 
how to make this participation a source of genuine prayer; [99] they should 
therefore give the people suitable guidance in the Christian understanding of 
the psalms, in order to progress by degrees to a greater appreciation and more 
frequent use of the prayer of the Church. [100]  

24. Communities of canons, monks, nuns, and other religious who celebrate the 
liturgy of the hours by rule or according to their constitutions, whether with 
the general rite or a particular rite, in whole or in part, represent in a 
special way the Church at prayer. They are a fuller sign of the Church as it 
continuously praises God with one voice and they fulfill the duty of "working," 
above all by prayer, "to build up and increase the whole Mystical Body of 
Christ, and for the good of the local Churches." [101] This is especially true 
of those living the contemplative life.  

25. Even when having no obligation to communal celebration, all sacred ministers 
and all clerics living in a community or meeting together should arrange to say 
at least some part of the liturgy of the hours in common, particularly morning 
prayer and evening prayer. [102]  

26. Men and women religious not bound to a common celebration, as well as 
members of any institute of perfection, are strongly urged to gather together, 
by themselves or with the people, to celebrate the liturgy of the hours or part 
of it.
 
27. Lay groups gathering for prayer, apostolic work, or any other reason are 
encouraged to fulfill the Church's duty, [103] by celebrating part of the 
liturgy of the hours. The laity must learn above all how in the liturgy they are 
adoring God the Father in spirit and in truth; [104] they should bear in mind 
that through public worship and prayer they reach all humanity and can 
contribute significantly to the salvation of the whole world. [105]  

Finally, it is of great advantage for the family, the domestic sanctuary of the 
Church, not only to pray together to God but also to celebrate some parts of the 
liturgy of the hours as occasion offers, in order to enter more deeply into the 
life of the Church. [106]  

B. MANDATE TO CELEBRATE THE LITURGY OF THE HOURS  

28. Sacred ministers have the liturgy of the hours entrusted to them in such a 
particular way that even when the faithful are not present they are to pray it 
themselves with the adaptations necessary under these circumstances. The Church 
commissions them to celebrate the liturgy of the hours so as to ensure at least 
in their persons the regular carrying out of the duty of the whole community and 
the unceasing continuance of Christ's prayer in the Church. [107]  

The bishop represents Christ in an eminent and conspicuous way and is the high 
priest of his flock; the life in Christ of his faithful people may be said in a 
sense to derive from him and depend on him. [108] He should, then, be the first 
of all the members of his Church in offering prayer. His prayer in the 
recitation of the liturgy of the hours is always made in the name of the Church 
and on behalf of the Church entrusted to him. [109]  

United as they are with the bishop and the whole presbyterium, priests are 
themselves representative in a special way of Christ the Priest [110] and so 
share the same responsibility of praying to God for the people entrusted to them 
and indeed for the whole world. [111]  

All these ministers fulfill the ministry of the Good Shepherd who prays for his
sheep that they may have life and so be brought into perfect unity. [112] In the
liturgy of the hours that the Church sets before them they are not only to find 
a source of devotion and a strengthening of personal prayer, [113] but must also 
nourish and foster pastoral missionary activity as the fruit of their 
contemplation to gladden the whole Church of God. [114]  

29. Hence bishops, priests, and other sacred ministers, who have received from 
the Church the mandate to celebrate the liturgy of the hours (see no. 17), 
should recite the full sequence of hours each day, observing as far as possible 
the true time of day.  

They should, first and foremost, attach due importance to those hours that are, 
so to speak, the two hinges of the liturgy of the hours, that is, morning prayer 
and evening prayer,, which should not be omitted except for a serious reason.  

They should faithfully pray the office of readings, which is above all a 
liturgical celebration of the word of God. In this way they fulfill daily a duty 
that is peculiarly their own, that is, of receiving the word of God into their 
lives, so that they may become more perfect as disciples of the Lord and 
experience more deeply the unfathomable riches of Christ. [115]  

In order to sanctify the whole day more completely, they will also treasure the 
recitation of daytime prayer and night prayer, to round off the whole Opus Dei
and to commend themselves to God before retiring.  

30. It is most fitting that permanent deacons recite daily at least some part of 
the liturgy of the hours, to be determined by the conference of bishops. [116]  

31. a. Cathedral and collegiate chapters should celebrate in choir those parts 
of the liturgy of the hours that are prescribed for them by the general law or 
by particular law.  

In private recitation individual members of these chapters should include those 
hours that are recited in their chapter, in addition to the hours prescribed for 
all sacred ministers. [117]  

b. Religious communities bound to the recitation of the liturgy of the hours and 
their individual members should celebrate the hours in keeping with their own 
particular law; but the prescription of no. 29 in regard to those in holy orders 
is to be respected.  

Communities bound to choir should celebrate the whole sequence of the hours 
daily in choir; [118] when absent from choir their members should recite the 
hours in keeping with their own particular law; but the prescriptions in no. 29 
are always to be respected.  

32. Other religious communities and their individual members are advised to 
celebrate some parts of the liturgy of the hours, in accordance with their own 
situation, for it is the prayer of the Church and makes the whole Church, 
scattered throughout the world, one in heart and mind. [119]
 
This recommendation applies also to laypersons. [120]  

C. STRUCTURE OF THE CELEBRATION  

33. The structure of the liturgy of the hours follows laws of its own and 
incorporates in its own way elements found in other Christian celebrations. Thus 
it is so constructed that, after a hymn, there is always psalmody, then a long 
or short reading of sacred Scripture, and finally prayer of petition.  

In a celebration in common and in private recitation the essential structure of 
this liturgy remains the same, that is, it is a conversation between God and his 
people. Celebration in common, however, expresses more clearly the ecclesial 
nature of the liturgy of the hours; it makes for active participation by all, in 
a way suited to each one's condition, through the acclamations, dialogue, 
alternating psalmody, and similar elements. It also better provides for the 
different literary genres that make up the liturgy of the hours. [121] Hence, 
whenever it is possible to have a celebration in common, with the people present 
and actively taking part, this kind of celebration is to be preferred to one 
that is individual and, as it were, private. [122] It is also advantageous to 
sing the office in choir and in community as opportunity Offers, in accordance 
with the nature and function of the individual parts.  

In this way the Apostle's exhortation is obeyed: "Let the word of Christ dwell 
in you in all its fullness, as you teach and counsel each other in all wisdom by 
psalms, hymns, and spiritual canticles, singing thankfully to God in your 
hearts" (Col 3:16; see Eph 5:19-20).

CHAPTER II  
SANCTIFICATION OF THE DAY: THE DIFFERENT LITURGICAL HOURS  

I. INTRODUCTION TO THE WHOLE OFFICE  

34. The whole office begins as a rule with an invitatory. This consists in the 
verse, Lord, open my lips. And my mouth will proclaim your praise, and Ps 95. 
This psalm invites the faithful each day to sing God's praise and to listen to 
his voice and draws them to hope for "the Lord's rest." [1]  

In place of Ps 95, Ps 100, Ps 67, or Ps 24 may be used as circumstances may 
suggest.  

It is preferable to recite the invitatory psalm responsorially as it is set out 
in the text, that is, with the antiphon recited at the beginning, then repeated, 
and repeated again after each strophe.  

35. The invitatory is placed at the beginning of the whole sequence of the day's 
prayer, that is, it precedes either morning prayer or the office of readings, 
whichever of these liturgical rites begins the day. The invitatory psalm with 
its antiphon may be omitted, however, when the invitatory is the prelude to 
morning prayer.  

36. The variation of the invitatory antiphon, to suit the different liturgical 
days, is indicated at its place of occurrence.

II. MORNING PRAYER AND EVENING PRAYER  

37. "By the venerable tradition of the universal Church, lauds as morning prayer 
and vespers as evening prayer are the two hinges on which the daily office 
turns; hence they are to be considered as the chief hours and celebrated as 
such." [2]  

38. As is clear from many of the elements that make it up, morning prayer is 
intended and arranged to sanctify the morning. St. Basil the Great gives an 
excellent description of this character in these words: "It is said in the 
morning in order that the first stirrings of our mind and will may be 
consecrated to God and that we may take nothing in hand until we have been 
gladdened by the thought of God, as it is written: 'I was mindful of God and was 
glad' (Ps 77:4 [Jerome's translation from Hebrew]), or set our bodies to any 
task before we do what has been said: 'I will pray to you, Lord, you will hear 
my voice in the morning; I will stand before you in the morning and gaze on you' 
(Ps 5:4-5)." [3]  

Celebrated as it is as the light of a new day is dawning, this hour also recalls 
the resurrection of the Lord Jesus, the true light enlightening all people (see 
Jn 1:9) and "the sun of justice" (Mal 4:2), "rising from on high" (Lk 1:78). 
Hence, we can well understand the advice of St. Cyprian: "There should be prayer 
in the morning so that the resurrection of the Lord may thus be celebrated." [4]  

39. When evening approaches and the day is already far spent, evening prayer is 
celebrated in order that "we may give thanks for what has been given us, or what 
we have done well, during the day." [5] We also recall the redemption through 
the prayer we send up "like incense in the Lord's sight," and in which "the 
raising up of our hands" becomes "an evening sacrifice." [6] This sacrifice "may 
also be interpreted more spiritually as the true evening sacrifice that our 
Savior the Lord entrusted to the apostles at supper on the evening when he 
instituted the sacred mysteries of the Church or of the evening sacrifice of the 
next day, the sacrifice, that is, which, raising his hands, he offered to the 
Father at the end of the ages for the salvation of the whole world." [7] Again, 
in order to fix our hope on the light that knows no setting, "we pray and make 
petition for the light to come down on us anew; we implore the coming of Christ 
who will bring the grace of eternal light." [8] Finally, at this hour we join 
with the Churches of the East in calling upon the "joy-giving light of that holy 
glory, born of the immortal, heavenly Father, the holy and blessed Jesus Christ; 
now that we have come to the setting of the sun and have seen the evening star, 
we sing in praise of God, Father, Son, and Holy Spirit. . . ."  

40. Morning prayer and evening prayer are therefore to be accorded the highest 
importance as the prayer of the Christian community. Their public or communal 
celebration should be encouraged, especially in the case of those who live in 
community. Indeed, the recitation of these hours should be recommended also to 
individual members of the faithful unable to take part in a celebration in 
common.
 
41. Morning prayer and evening prayer begin with the introductory verse, God 
come to my assistance. Lord, make haste to help me. There follows the Glory to 
the Father, with As it was in the beginning and Alleluia (omitted in Lent). This 
introduction is omitted at morning prayer when the invitatory immediately 
precedes it.  

42. Then an appropriate hymn is sung immediately. The purpose of the hymn is to
set the tone for the hour or the feast and, especially in celebrations with a 
congregation, to form a simple and pleasant introduction to prayer.  

43. After the hymn the psalmody follows, in accordance with the rules laid down 
in nos. 121-125. The psalmody of morning prayer consists of one morning psalm, 
then a canticle from the Old Testament and, finally, a second psalm of praise, 
following the tradition of the Church.  

The psalmody of evening prayer consists of two psalms (or two parts of a longer 
psalm) suited to the hour and to celebration with a congregation and a canticle 
from the letters of the apostles or from the Book of Revelation.  

44. After the psalmody there is either a short reading or a longer one.  

45. The short reading is provided to fit the day, the season, and the feast. It 
is to be read and received as a true proclamation of God's word that emphasizes 
some holy thought or highlights some shorter passages that may be overlooked in 
the continuous cycle of Scripture readings.  

The short readings are different for each day of the psalter cycle.  

46. Especially in a celebration with a congregation, a longer Scripture reading 
may be chosen either from the office of readings or the Lectionary for Mass, 
particularly texts that for some reason have not been used. From time to time 
some other more suitable reading may be used, in accordance with the rules in 
nos. 248-249 and 251.
47. In a celebration with a congregation a short homily may follow the reading 
to explain its meaning, as circumstances suggest.  

48. After the reading or homily a period of silence may be observed.  

49. As a response to the word of God, a responsorial. chant or short responsory 
is provided; this may be omitted. Other chants with the same purpose and 
character may also be substituted in its place, provided these have been duly 
approved by the conference of bishops.  

50. Next is the solemn recitation of the gospel canticle with its antiphon, that 
is, the Canticle of Zechariah at morning prayer and the Canticle of Mary at 
evening prayer. Sanctioned by age-old popular usage in the Roman Church, these 
canticles are expressions of praise and thanksgiving for our redemption. The 
antiphon for each canticle is indicated, according to the character of the day, 
the season, or the feast.  

51. After the canticle, at morning prayer come the petitions for the 
consecration of the day and its work to God and at evening prayer, the 
intercessions (see nos. 179-193).  

52. After the petitions or intercessions the Lord's Prayer is said by all.
 
53. Immediately after the Lord's Prayer there follows the concluding prayer, 
which for weekdays in Ordinary Time is found in the psalter and for other days 
in the proper.  

54. Then, if a priest or deacon is presiding, he dismisses the congregation with 
the greeting, The Lord be with you, and the blessing as at Mass. He adds the 
invitation, Go in peace. R. Thanks be to God. In the absence of a priest or 
deacon the celebration concludes with May the Lord bless us, etc.

III. OFFICE OF READINGS  

55. The office of readings seeks to provide God's people, and in particular 
those consecrated to God in a special way, with a wider selection of passages 
from sacred Scripture for meditation, together with the finest excerpts from 
spiritual writers. Even though the cycle of scriptural readings at daily Mass is 
now richer, the treasures of revelation and tradition to be found in the office 
of readings will also contribute greatly to the spiritual life. Bishops and 
priests in particular should prize these treasures, so that they may hand on to 
others the word of God they have themselves received and make their teaching 
"the true nourishment for the people of God." [9]  

56. But prayer should accompany "the reading of sacred Scripture so that there 
may be a conversation between God and his people: 'we talk with God when we 
pray, we listen to him when we read God's words." [10] For this reason the 
office of readings consists also of psalms, a hymn, a prayer, and other texts, 
giving it the character of true prayer.  

57. The Constitution on the Liturgy directs that the office of readings, "though 
it should retain its character as a night office of praise when celebrated in 
choir, shall be adapted so that it may be recited at any hour of the day; it 
shall be made up of fewer psalms and longer readings." [11]  

58. Those who are obliged by their own particular law and others who commendably 
wish to retain the character of this office as a night office of praise (either 
by saying it at night or very early in the morning and before morning prayer), 
during Ordinary Time choose the hymn from the selection given for this purpose. 
Moreover, for Sundays, solemnities, and certain feasts what is said in nos. 
70-73 about vigils must be kept in mind.  

59. Without prejudice to the regulations just given, the office of readings may 
be recited at any hour of the day, even during the night hours of the previous 
day, after evening prayer has been said.  

60. If the office of readings is said before morning prayer, the invitatory 
precedes it, as noted (nos. 34-36). Otherwise it begins with the verse, God, 
come to my assistance with the Glory to the Father, As it was in the beginning, 
and the Alleluia (omitted in Lent).  

61. Then the hymn is sung. In Ordinary Time this is taken either from the night 
selections, as already indicated (nos. 34-36), or from the morning selections, 
depending on what the true time of day requires.
 
62. The psalmody follows and consists of three psalms (or parts in the case of 
longer psalms). During the Easter triduum, on days within the octaves of Easter 
and Christmas, on solemnities and feasts, the psalms are proper, with their 
proper antiphons.  

On Sundays and weekdays, however, the psalms and their antiphons are taken from 
the current week and day of the psalter. On memorials of the saints they are 
similarly taken from the current week and day of the psalter, unless there are 
proper psalms or antiphons (see nos. 218ff.).  

63. Between the psalmody and the readings there is, as a rule, a verse, marking 
a transition in the prayer from psalmody to listening.  

64. There are two readings: the first is from the Scriptures, the second is from 
the writings of the Fathers or church writers, or else is a reading connected 
with the saints.  

65. After each reading there is a responsory (see nos. 169-172).  

66. The scriptural reading is normally to be taken from the Proper of Seasons, 
in accordance with the rules to be given later (nos. 140-155). On solemnities 
and feasts, however, it is taken from the proper or the common.  

67. On solemnities and feasts of saints a proper second reading is used; if 
there is none, the second reading is taken from the respective Common of Saints. 
On memorials of saints when the celebration is not impeded, the reading in 
connection with the saint replaces the current second reading (see nos. 166 and
235).  

68. On Sundays outside Lent, on days within the octaves of Easter and Christmas, 
and on solemnities and feasts the Te Deum is said after the second reading with 
its responsory but is omitted on memorials and weekdays. The last part of this 
hymn, that is, from the verse, Save your people, Lord to the end, may be 
omitted.  

69. The office of readings normally concludes with the prayer proper to the day 
and, at least in recitation in common, with the acclamation, Let us praise the 
Lord. R. And give him thanks.

IV. VIGILS  

70. The Easter Vigil is celebrated by the whole Church, in the rites given in 
the relevant liturgical books. "The vigil of this night," as St. Augustine said, 
"is of such importance that it could claim exclusively for itself the name 
'vigil,' common though this is to all the others." [12] "We keep vigil on that
night when the Lord rose again and inaugurated for us in his humanity that 
life ... in which there is neither death nor sleep.... Hence, the one whose
resurrection we celebrate by keeping watch a little longer will see to it that 
we reign with him by living a life without end." [13]  

71. As with the Easter Vigil, it was customary to begin certain solemnities 
(different in different Churches) with a vigil. Among these solemnities 
Christmas and Pentecost are preeminent. This custom should be maintained and 
fostered, according to the particular usage of each Church. Whenever it seems 
good to add a vigil for other solemnities or pilgrimages, the general norms for 
celebrations of the word should be followed.  

72. The Fathers and spiritual writers have frequently encouraged Christians, 
especially those who lead the contemplative life, to pray during the night. Such 
prayer expresses and awakens our expectation of the Lord's Second Coming: "At 
midnight the cry went up: 'See, the bridegroom is coming, go out to meet him... 
(Mt 25:6). "Keep watch, then, for you do not know when the master of the house 
is coming, whether late or at midnight or at cockcrow or in the morning, so that 
if he comes unexpectedly he may not find you sleeping" (Mk 13:35-36). All who 
maintain the character of the office of readings as a night office, therefore, 
are to be commended.  

73. Further, since in the Roman Rite the office of readings is always of a 
uniform brevity, especially for the sake of those engaged in apostolic work, 
those who desire, in accordance with tradition, to extend the celebration of the 
vigils of Sundays, solemnities, and feasts should do so as follows.  

First, the office of readings is to be celebrated as in The Liturgy of the Hours 
up to the end of the readings. After the two readings and before the Te Deum 
canticles should be added from the special appendix of The Liturgy of the Hours. 
Then the gospel should be read; a homily on the gospel may be added. After this 
the Te Deum is sung and the prayer said.  

On solemnities and feasts the gospel is to be taken from the Lectionary for 
Mass; on Sundays, from the series on the paschal mystery in the appendix of The 
Liturgy of the Hours.

V. DAYTIME HOURS  

74. Following a very ancient tradition Christians have made a practice of 
praying out of private devotion at various times of the day, even in the course 
of their work, in imitation of the Church in apostolic times. In different ways 
with the passage of time this tradition has taken the form of a liturgical 
celebration.  

75. Liturgical custom in both East and West has retained midmorning, midday, and 
midafternoon prayer, mainly because these hours were linked to a commemoration
of the events of the Lord's passion and of the first preaching of the Gospel.  

76. Vatican Council II decreed that these lesser hours are to be retained in 
choir. [14]  

The liturgical practice of saying these three hours is to be retained, without 
prejudice to particular law, by those who live the contemplative life. It is 
recommended also for all, especially those who take part in retreats or pastoral 
meetings.  

77. Outside choir, without prejudice to particular law, it is permitted to 
choose from the three hours the one most appropriate to the time of day, so that 
the tradition of prayer in the course of the day's work may be maintained.  

78. Daytime prayer is so arranged as to take into account both those who recite 
only one hour and those who are obliged, or desire, to say all three hours.  

79. The daytime hours begin with the introductory verse, God come to my 
assistance with the Glory to the Father, As it was in the beginning, and the 
Alleluia (omitted in Lent).
 
Then a hymn appropriate to the hour is sung. The psalmody is next, then the 
reading, followed by the verse. The hour concludes with the prayer and, at least 
in recitation in common, with the acclamation, Let us praise the Lord. R. And 
give him thanks.  

80. Different hymns and prayers are given for each of the hours so that, in 
keeping with tradition, they may correspond to the true time of day and thus 
sanctify it in a more pointed way. Those who recite only one hour should 
therefore choose the texts that correspond to the true time of day.  

In addition, the readings and prayers vary in keeping with the character of the 
day, the season, or the feast.  

81. Two psalmodies are provided: the current psalmody and the complementary 
psalmody. Those who pray one hour should use the current psalmody. Those who 
pray more than one hour should use the current psalmody at one hour and the 
complementary psalmody at the others.  

82. The current psalmody consists of three psalms (or parts in the case of 
longer psalms) from the psalter, with their antiphons, unless directions are 
given to the contrary.  

On solemnities, the Easter triduum, and days within the octave of Easter, proper 
antiphons are said with three psalms chosen from the complementary psalmody, 
unless special psalms are to be used or the celebration falls on a Sunday, when 
the psalms are those from the Sunday of Week I of the psalter.  

83. The complementary psalter consists of three sets of three psalms, chosen as 
a rule from the Gradual Psalms.

VI. NIGHT PRAYER  

84. Night prayer is the last prayer of the day, said before retiring, even if 
that is after midnight.  

85. Night prayer begins like the other hours, with the verse, God, come to my 
assistance, the Glory to the Father, As it was in the beginning, and the 
Alleluia (omitted in Lent).  

86. It is a laudable practice to have next an examination of conscience; in a 
celebration in common this takes place in silence or as part of a penitential 
rite based on the formularies in the Roman Missal.  

87. The appropriate hymn follows.  

88. After evening prayer I of Sunday the psalmody consists of Ps 4 and Ps 134; 
after evening prayer II of Sunday it consists of Ps 91.  

On the other days psalms are chosen that are full of confidence in the Lord; it 
is permissible to use the Sunday psalms instead, especially for the convenience 
of those who may wish to pray night prayer from memory.  

89. After the psalmody there is a reading, followed by the responsory, Into your 
hands. Then, as a climax to the whole hour, the Canticle of Simeon, Lord, now 
you let your servant go in peace follows, with its antiphon.  

90. The concluding prayer then follows, as it appears in the psalter.
 
91. After the prayer the blessing, May the all-powerful Lord is used, even in 
private recitation.  

92. Finally, one of the antiphons in honor of the Blessed Virgin Mary is said. 
In the Easter season this is always to be the Regina caeli. In addition to the 
antiphons given in The Liturgy of the Hours, others may be approved by the 
conferences of bishops. [15]

VII. COMBINING THE HOURS WITH MASS OR WITH EACH OTHER  

93. In particular cases, if circumstances require, it is possible to link an 
hour more closely with Mass when there is a celebration of the liturgy of the 
hours in public or in common, according to the norms that follow, provided the 
Mass and the hour belong to one and the same office. Care must be taken, 
however, that this does not result in harm to pastoral work, especially on
Sundays.  

94. When morning prayer, celebrated in choir or in common, comes immediately 
before Mass, the whole celebration may begin either with the introductory verse 
and hymn of morning prayer, especially on weekdays, or with the entrance song, 
procession, and celebrant's greeting, especially on Sundays and holydays; one of 
the introductory rites is thus omitted.  

The psalmody of morning prayer follows as usual, up to, but excluding, the
reading. After the psalmody the penitential rite is omitted and, as 
circumstances suggest, the Kyrie; the Gloria then follows, if required by the 
rubrics, and the celebrant says the opening prayer of the Mass. The liturgy of 
the word follows as usual.  

The general intercessions are made in the place and form customary at Mass. But 
on weekdays, at Mass in the morning, the intercessions of morning prayer may 
replace the daily form of the general intercessions at Mass.  

After the communion with its communion song the Canticle of Zechariah, Blessed 
be the Lord, with its antiphon from morning prayer, is sung. Then follow the 
prayer after communion and the rest as usual.  

95. If public celebration of a daytime hour, whichever corresponds to the time 
of day, is immediately followed by Mass, the whole celebration may begin in the 
same way, either with the introductory verse and hymn for the hour, especially 
on weekdays, or with the entrance song, procession, and celebrant's greeting, 
especially on Sundays and holydays; one of the introductory rites is thus 
omitted.  

The psalmody of the hour follows as usual up to, but excluding, the reading. 
After the psalmody the penitential rite is omitted and, as circumstances 
suggest, the Kyrie; the Gloria then follows, if required by the rubrics, and the 
celebrant says the opening prayer of the Mass.  

96. Evening prayer, celebrated immediately before Mass, is joined to it in the 
same way as morning prayer. Evening prayer I of solemnities, Sundays, or feasts 
of the Lord falling on Sundays may not be celebrated until after Mass of the 
preceding day or Saturday.  

97. When a daytime hour or evening prayer follows Mass, the Mass is celebrated 
in the usual way up to and including the prayer after communion.  

When the prayer after communion has been said, the psalmody of the hour begins 
without introduction. At the daytime hour, after the psalmody the short reading 
is omitted and the prayer is said at once and the dismissal takes place as at 
Mass. At evening prayer, after the psalmody the short reading is omitted and 
the Canticle of Mary with its antiphon follows at once; the intercessions and 
the Lord's Prayer are omitted; the concluding prayer follows, then the blessing 
of the congregation.  

98. Apart from Christmas eve, the combining of Mass with the office of readings 
is normally excluded, since the Mass already has its own cycle of readings, to 
be kept distinct from any other. But if by way of exception, it should be 
necessary to join the two, then immediately after the second reading from the 
office, with its responsory, the rest is omitted and the Mass begins with the 
Gloria, if it is called for; otherwise the Mass begins with the opening prayer.  

99. If the office of readings comes immediately before another hour of the 
office, then the appropriate hymn for that hour may be sung at the beginning of 
the office of readings. At the end of the office of readings the prayer and 
conclusion are omitted and in the hour following the introductory verse with the 
Glory to the Father is omitted.

CHAPTER III  
DIFFERENT ELEMENTS IN THE LITURGY OF THE HOURS  

I. PSALMS AND THEIR CONNECTION WITH CHRISTIAN PRAYER  

100. In the liturgy of the hours the Church in large measure prays through the 
magnificent songs that the Old Testament authors composed under the inspiration 
of the Holy Spirit. The origin of these verses gives them great power to raise 
the mind to God, to inspire devotion, to evoke gratitude in times of favor, and 
to bring consolation and courage in times of trial.  

101. The psalms, however, are only a foreshadowing of the fullness of time that 
came to pass in Christ the Lord and that is the source of the power of the 
Church's prayer. Hence, while the Christian people are all agreed on the supreme 
value to be placed on the psalms, they can sometimes experience difficulty in 
making this inspired poetry their own prayer.  

102. Yet the Holy Spirit, under whose inspiration the psalms were written, is 
always present by his grace to those believers who use them with good will. But 
more is necessary: the faithful must "improve their understanding of the Bible,  
especially of the psalms," [1] according to their individual capacity, so that 
they may understand how and by what method they can truly pray through the 
psalms.  

103. The psalms are not readings or prose prayers, but poems of praise. They can
on occasion be recited as readings, but from their literary genre they are 
properly called Tehillim ("songs of praise") in Hebrew and psalmoi ("songs to be 
sung to the lyre") in Greek. In fact, all the psalms have a musical quality that 
determines their correct style of delivery. Thus even when a psalm is recited 
and not sung or is said silently in private, its musical character should govern 
its use. A psalm does present a text to the minds of the people, but its aim is 
to move the heart of those singing it or listening to it and also of those 
accompanying it "on the lyre and harp."  

104. To sing the psalms with understanding, then, is to meditate on them verse 
by verse, with the heart always ready to respond in the way the Holy Spirit 
desires.
 
The one who inspired the psalmist will also be present to those who in faith and 
love are ready to receive his grace. For this reason the singing of psalms, 
though it demands the reverence owed to God's majesty, should be the expression 
of a joyful spirit and a loving heart, in keeping with their character as sacred 
poetry and divine song and above all with the freedom of the children of God.  

105. Often the words of a psalm help us to pray with greater ease and fervor, 
whether in thanksgiving and joyful praise of God or in prayer for help in the 
throes of suffering. But difficulties may arise, especially when the psalm is 
not addressed directly to God. The psalmist is a poet and often addresses the 
people as he recalls Israel's history; sometimes he addresses others, including 
subrational creatures. He even represents the words as being spoken by God 
himself and individual people, including, as in Ps 2, God's enemies. This shows 
that a psalm is a different kind of prayer from a prayer or collect composed by 
the Church. Moreover, it is in keeping with the poetic and musical character of 
the psalms that they do not necessarily address God but are sung in God's 
presence. Thus St. Benedict's instruction: "Let us reflect on what it means to 
be in the sight of God and his angels, and let us so stand in his presence that 
our minds are in harmony with our voices." [2]  

106. In praying the psalms we should open our hearts to the different attitudes 
they express, varying with the literary genre to which each belongs (psalms of 
grief, trust, gratitude, etc.) and to which biblical scholars rightly attach 
great importance.  

107. Staying close to the meaning of the words, the person who prays the psalms 
looks for the significance of the text for the human life of the believer.  

It is clear that each psalm was written in its own individual circumstances, 
which the titles given for each psalm in the Hebrew psalter are meant to 
indicate. But whatever its historical origin, each psalm has its own meaning, 
which we cannot overlook even in our own day. Though the psalms originated very 
many centuries ago among an Eastern people, they express accurately the pain and 
hope, the unhappiness and trust of people of every age and country, and sing 
above all of faith in God, of revelation, and of redemption.  

108. Those who pray the psalms in the liturgy of the hours do so not so much in 
their own name as in the name of the entire Body of Christ. This consideration 
does away with the problem of a possible discrepancy between personal feelings 
and the sentiments a psalm is expressing: for example, when a person feels sad 
and the psalm is one of joy or when a person feels happy and the psalm is one of 
mourning. Such a problem is readily solved in private prayer, which allows for 
the choice of a psalm suited to personal feelings. The divine office, however, 
is not private; the cycle of psalms is public, in the name of the Church, even 
for those who may be reciting an hour alone. Those who pray the psalms in the 
name of the Church nevertheless can always find a reason for joy or sadness, for 
the saying of the Apostle applies in this case also: "Rejoice with the joyful 
and weep with those who weep" (Rom 12:15). In this way human frailty, wounded 
by self-love, is healed in proportion to the love that makes the heart match the 
voice that prays the psalms. [3]  

109. Those who pray the psalms in the name of the Church should be aware of 
their full sense (sensus plenus), especially their Messianic sense, which was 
the reason for the Church's introduction of the psalter into its prayer. This 
Messianic sense was fully revealed in the New Testament and indeed was affirmed 
publicly by Christ the Lord in person when he said to the apostles: "All that is 
written about me in the law of Moses and the prophets and the psalms must be 
fulfilled" (Lk 24:44). The best-known example of this Messianic sense is the 
dialogue in Matthew's Gospel on the Messiah as Son of David and David's Lord, 
[4] where Ps 110 is interpreted as Messianic.  

Following this line of thought, the Fathers of the Church saw the whole psalter 
as a prophecy of Christ and the Church and explained it in this sense; for the 
same reason the psalms have been chosen for use in the liturgy. Though somewhat 
contrived interpretations were at times proposed, in general the Fathers and the 
liturgy itself had the right to hear in the singing of the psalms the voice of 
Christ crying out to the Father or of the Father conversing with the Son; 
indeed, they also recognized in the psalms the voice of the Church, the 
apostles, and the martyrs. This method of interpretation also flourished in the 
Middle Ages; in many manuscripts of the period the Christological meaning of 
each psalm was set before those praying by means of the caption prefixed. A 
Christological meaning is by no means confined to the recognized Messianic 
psalms but is given also to many others. Some of these interpretations are 
doubtless Christological only in an accommodated sense, but they have the 
support of the Church's tradition.  

On the great feasts especially, the choice of psalms is often based on their 
Christological meaning and antiphons taken from these psalms are frequently used 
to throw light on this meaning.

II. ANTIPHONS AND OTHER AIDS TO PRAYING THE PSALMS  

110. In the Latin tradition of psalmody three elements have greatly contributed 
to an understanding of the psalms and their use as Christian prayer: the 
captions, the psalm-prayers, and in particular the antiphons.  

111. In the psalter of The Liturgy of the Hours a caption is given for each
psalm to explain its meaning and its import for the personal life of the 
believer. These captions are intended only as an aid to prayer. A quotation from 
the New Testament or the Fathers of the Church is added to foster prayer in the 
light of Christ's new revelation; it is an invitation to pray the psalms in 
their Christological meaning.  

112. Psalm-prayers for each psalm are given in the supplement to The Liturgy of 
the Hours as an aid to understanding them in a predominantly Christian way. An 
ancient tradition provides a model for their use: after the psalm a period of 
silence is observed, then the prayer gives a resume and resolution of the 
thoughts and aspirations of those praying the psalms.  

113. Even when the liturgy of the hours is recited, not sung, each psalm retains 
its own antiphon, which is also to be said in private recitation. The antiphons 
help to bring out the literary genre of the psalm; they highlight some theme 
that may otherwise not attract the attention it deserves; they suggest an 
individual tone in a psalm, varying with different contexts: indeed, as long as 
farfetched accommodated senses are avoided, antiphons are of great value in 
helping toward an understanding of the typological meaning or the meaning 
appropriate to the feast; they can also add pleasure and variety to the 
recitation of the psalms.  

114. The antiphons in the psalter have been designed to lend themselves to 
vernacular translation and to repetition after each strophe, in accordance with 
no. 125.
 
When the office of Ordinary Time is recited, not sung, the quotations printed 
with the psalms may be used in place of these antiphons (see no. 111).  

115. When a psalm may be divided because of its length into several sections 
within one and the same hour, an antiphon is given for each section. This is to 
provide variety, especially when the hour is sung, and also to help toward a 
better understanding of the riches of the psalm. Still, it is permissible to say 
or sing the complete psalm without interruption, using only the first antiphon.  

116. Proper antiphons are given for each of the psalms of morning prayer and 
evening prayer during the Easter triduum, on the days within the octaves of 
Easter and Christmas, on the Sundays of the seasons of Advent, Christmas, Lent, 
and Easter, on the weekdays of Holy Week and the Easter season, and from the 
17th to the 24th of December.  

117. On solemnities proper antiphons are given for the office of readings, 
morning prayer, the daytime hours, and evening prayer; if not, the antiphons are 
taken from the common. On feasts the same applies to the office of readings and 
to morning prayer and evening prayer.  

118. Any memorials of the saints that have proper antiphons retain them (see no. 
235).  

119. The antiphons for the Canticles of Zechariah and of Mary are taken, during
Ordinary Time, from the Proper of Seasons, if they are given there; if not, they 
are taken from the current week and day of the psalter. On solemnities and 
feasts they are taken from the proper if they are given there; if not, they are 
taken from the common. On memorials without proper antiphons the antiphon may be 
taken at will either from the common or from the current week.  

120. During the Easter season Alleluia is added to all antiphons, unless it 
would clash with the meaning of a particular antiphon.

III. WAYS OF SINGING THE PSALMS  

121. Different psalms may be sung in different ways for a fuller grasp of their 
spiritual meaning and beauty. The choice of ways is dictated by the literary 
genre or length of each psalm, by the language used, whether Latin or the 
vernacular, and especially by the kind of celebration, whether individual, with 
a group, or with a congregation. The reason for using psalms is not the 
establishment of a fixed amount of prayer but their own variety and the 
character proper to each.  

122. The psalms are sung or said in one of three ways, according to the 
different usages established in tradition or experience: directly (in diredum), 
that is, all sing the entire psalm, or antiphonally, that is, two choirs or 
sections of the congregation sing alternate verses or strophes, or 
responsorially.  

123. At the beginning of each psalm its own antiphon is always to be recited, as 
noted in nos. 113-120. At the end of the psalm the practice of concluding with 
the Glory to the Father and As it was in the beginning is retained. This is the 
fitting conclusion endorsed by tradition and it gives to Old Testament prayer a 
note of praise and a Christological and Trinitarian sense. The antiphon may be 
repeated at the end of the psalm.
 
124. When longer psalms occur, sections are marked in the psalter that divide 
the parts in such a way as to keep the threefold structure of the hour; but 
great care has been taken not to distort the meaning of the psalm.
It is useful to observe this division, especially in a choral celebration in 
Latin; the Glory to the Father is added at the end of each section.  

It is permissible, however, either to keep this traditional way or to pause 
between the different sections of the same psalm or to recite the whole psalm 
and its antiphon as a single unit without a break.  

125. In addition, when the literary genre of a psalm suggests it, the divisions 
into strophes are marked in order that, especially when the psalm is sung in the 
vernacular, the antiphons may be repeated after each strophe; in this case the
Glory to the Father need be said only at the end of the psalm.

IV. PLAN FOR THE DISTRIBUTION OF THE PSALMS IN THE OFFICE  

126. The psalms are distributed over a four-week cycle in such a way that very 
few psalms are omitted, while some, traditionally more important, occur more 
frequently than others; morning prayer and evening prayer as well as night 
prayer have been assigned psalms appropriate to these hours. [5]  

127. Since morning prayer and evening prayer are particularly designed for 
celebration with a congregation, the psalms chosen for them are those more 
suited to this purpose.  

128. For night prayer the norm given in no. 88 has been followed.  

129. For Sunday, including its office of readings and daytime prayer, the psalms 
chosen are those that tradition has particularly singled out as expressions of 
the paschal mystery. Certain psalms of a penitential character or connected with 
the passion are assigned to Friday.  

130. Three psalms (78, 105, and 106) are reserved for the seasons of Advent, 
Christmas, Lent, and Easter, because they throw a special light on the Old 
Testament history of salvation as the forerunner of its fulfillment in the New.  

131. Three psalms (58, 83, and 109) have been omitted from the psalter cycle 
because of their curses; in the same way, some verses have been omitted from 
certain psalms, as noted at the head of each. The reason for the omission is a 
certain psychological difficulty, even though the psalms of imprecation are in 
fact used as prayer in the New Testament, for example, Rv 6:10, and in no sense 
to encourage the use of curses.  

132. Psalms too long to be included in one hour of the office are assigned to 
the same hour on different days so that they may be recited in full by those who 
do not usually say other hours. Thus Ps 119 is divided in keeping with its own 
internal structure and is spread over twenty-two days during daytime prayer, 
because tradition has assigned it to the day hours.  

133. The four-week cycle of the psalter is coordinated with the liturgical year 
in such a way that on the First Sunday of Advent, the First Sunday in Ordinary 
Time, the First Sunday of Lent, and Easter Sunday the cycle is always begun 
again with Week I (others being omitted when necessary).  

After Pentecost, when the psalter cycle follows the series of weeks in Ordinary
Time, it ' begins with the week indicated in the Proper of Seasons at the 
beginning of the appropriate week in Ordinary Time.  

134. On solemnities and feasts, during the Easter triduum, and on the days 
within the octaves of Easter and Christmas, proper psalms are assigned to the 
office of readings from those with a tradition of use at these times and their
relevance is generally highlighted by the choice of antiphon. This is also the 
case at daytime prayer on certain solemnities of the Lord and during the octave 
of Easter. At morning prayer the psalms and canticle are taken from the Sunday 
of the Week I of the psalter. On solemnities the psalms at evening prayer I are 
taken from the Laudate Psalms, following an ancient custom. At evening prayer II 
on solemnities and at evening prayer on feasts the psalms and canticle are 
proper. At daytime prayer on solemnities (except those already mentioned and 
those falling on Sunday) the psalms are taken from the Gradual Psalms; at 
daytime prayer on feasts the psalms are those of the current week and day of the 
psalter.  

135. In all other cases the psalms are taken from the current week and day of 
the psalter, unless there are proper antiphons or proper psalms.

V. CANTICLES FROM THE OLD AND NEW TESTAMENTS  

136. At morning prayer between the first and the second psalm a canticle from 
the Old Testament is inserted, in accordance with custom. In addition to the 
series handed down from the ancient Roman tradition and the other series 
introduced into the breviary by St. Pius X, several other canticles have been 
added to the psalter from different books of the Old Testament, in order that 
each weekday of the four-week cycle may have its own proper canticle and on 
Sunday the two sections of the Canticle of the Three Children may be alternated.  

137. At evening prayer, after the two psalms, a canticle of the New Testament is 
inserted, from the letters of the apostles or the Book of Revelation. Seven 
canticles are given for each week of the four-week cycle, one for each day. On 
the Sundays of Lent, however, in place of the Alleluia Canticle from the Book of 
Revelation, the canticle is from the First Letter of Peter. In addition, on the 
solemnity of the Epiphany and the feast of the Transfiguration the canticle is 
from the First Letter to Timothy; this is indicated in those offices.  

138. The gospel Canticles of Zechariah, of Mary, and of Simeon are to be treated 
with the same solemnity and dignity as are customary at the proclamation of the 
gospel itself.  

139. Both psalmody and readings are arranged in keeping with the received rule 
of tradition that the Old Testament is read first, then the writings of the 
apostles, and finally the gospel.  

Top of Page

VI. READINGS FROM SACRED SCRIPTURE  

A. READING OF SACRED SCRIPTURE IN GENERAL  

140. The reading of sacred Scripture, which, following an ancient tradition, 
takes place publicly in the liturgy, is to have special importance for all 
Christians, not only in the celebration of the eucharist but also in the divine 
office. The reason is that this reading is not the result of individual choice 
or devotion but is the planned decision of the Church itself, in order that in 
the course of the year the Bride of Christ may unfold the mystery of Christ 
"from his incarnation and birth until his ascension, the day of Pentecost, and 
the expectation of blessed hope and of the Lord's return." [6] In addition, the 
reading of sacred Scripture in the liturgical celebration is always accompanied 
by prayer in order that the reading may have greater effect and that, in turn, 
prayer - especially the praying of the psalms - may gain fuller understanding 
and become more fervent and devout because of the reading.  

141. In the liturgy of the hours there is a longer reading of sacred Scripture 
and a shorter reading.  

142. The longer reading, optional at morning prayer and evening prayer, is
described in no. 46.  

B. CYCLE OF SCRIPTURE READINGS IN THE OFFICE OF READINGS  

143. The cycle of readings from sacred Scripture in the office of readings takes 
into account both those special seasons during which by an ancient tradition 
particular books are to be read and the cycle of readings at Mass. The liturgy 
of the hours is thus coordinated with the Mass in such a way that the scriptural 
readings in the office complement the readings at Mass and so provide a complete 
view of the history of salvation.  

144. Without prejudice to the exception noted in no. 73, there are no readings 
from the Gospel in the liturgy of the hours, since in the Mass each year the 
Gospel is read in its entirety.  

145. There are two cycles of biblical readings. The first is a one-year cycle 
and is incorporated into The Liturgy of the Hours; the second, given in the 
supplement for optional use, is a two-year cycle, like the cycle of readings at 
weekday Masses in Ordinary Time.  

146. The two-year cycle of readings for the liturgy of the hours is so arranged 
that each year there are readings from nearly all the books of sacred Scripture 
as well as longer and more difficult texts that are not suitable for inclusion 
in the Mass. The New Testament as a whole is read each year, partly in the Mass, 
partly in the liturgy of the hours; but for the Old Testament books a selection  
has been made of those parts that are of greater importance for the 
understanding of the history of salvation and for deepening devotion.  

The complementarity between the readings in the liturgy of the hours and in the 
Mass in no way assigns the same texts to the same days or spreads the same books 
over the same seasons. This would leave the liturgy of the hours with the less 
important passages and upset the sequence of texts. Rather this complementarity 
necessarily demands that the same book be used in the Mass and in the liturgy of 
the hours in alternate years or that, if it is read in the same year, there be 
some interval in between.  

147. During Advent, following an ancient tradition, passages are read from 
Isaiah in a semicontinuous sequence, alternating in a two-year cycle. In 
addition, the Book of Ruth and certain prophecies from Micah are read. Since 
there are special readings from 17 to 24 December (both dates included), 
readings for the Third Week of Advent which fall on these dates are omitted.
 
148. From 29 December until 5 January the readings for Year I are taken from the 
Letter to the Colossians (which considers the incarnation of the Lord within the 
context of the whole history of salvation) and the readings for Year II are 
taken from the Song of Songs (which foreshadows the union of God and humanity in 
Christ): "God the Father prepared a wedding feast for God his Son when he united 
him with human nature in the womb of the Virgin, when he who is God before all 
ages willed that his Son should become man at the end of the ages. [7]  

149. From 7 January until the Saturday after the Epiphany the readings are 
eschatological texts from Isaiah 60-66 and Baruch. Readings remaining unused are 
omitted for that year.  

150. During Lent the readings for the first year are passages from Deuteronomy 
and the Letter to the Hebrews. Those for the second year review the history of 
salvation from Exodus, Leviticus, and Numbers. The Letter to the Hebrews 
interprets the Old Covenant in the light of the paschal mystery of Christ. A 
passage from the same letter, on Christ's sacrifice (Heb 9:11-28), is read on 
Good Friday; another, on the Lord's rest (Heb 4:1-16), is read on Holy Saturday. 
On the other days of Holy Week the readings in Year I are the third and fourth 
Songs of the Servant of the Lord and extracts from Lamentations; in Year II the 
prophet Jeremiah is read, as a type of Christ in his passion.  

151. During the Easter season, apart from the First and Second Sundays of Easter 
and the solemnities of the Ascension and Pentecost, there are the traditional 
readings from the First Letter of Peter, the Book of Revelation, and the Letters 
of John (for Year 1), and from the Acts of the Apostles (for Year II).  

152. From the Monday after the feast of the Baptism of the Lord until Lent and 
from the Monday after Pentecost until Advent there is a continuous series of 
thirty-four weeks in Ordinary Time.  

This series is interrupted from Ash Wednesday until Pentecost. On the Monday 
after Pentecost Sunday the cycle of readings in Ordinary Time is resumed, 
beginning with the week after the one interrupted because of Lent; the reading 
assigned to the Sunday is omitted.  

In years with only thirty-three weeks in Ordinary Time, the week immediately 
following Pentecost is dropped, in order to retain the readings of the last
weeks which are eschatological readings.  

The books of the Old Testament are arranged so as to follow the history of 
salvation: God reveals himself in the history of his people as he leads and 
enlightens them in progressive stages. This is why prophetic books are read 
along with the historical books, but with due consideration of the period in 
which the prophets lived and taught. Hence, the cycle of readings from the Old 
Testament contains, in Year I, the historical books and prophetic utterances 
from the Book of Joshua as far as, and including, the time of the exile. In Year
II, after the readings from Genesis (read before Lent), the history of salvation 
is resumed after the exile up to the time of the Maccabees. Year II includes the 
later prophets, the wisdom literature, and the narratives in Esther, Tobit, and 
Judith.  

The letters of the apostles not read at special times are distributed through 
the year in a way that takes into account the readings at Mass and the 
chronological order in which these letters were written.
 
153. The one-year cycle is shortened in such a way that each year special 
passages from sacred Scripture are read, but in correlation with the two-year 
cycle of readings at Mass, to which it is intended to be complementary.  

154. Proper readings are assigned for solemnities and feasts; otherwise the 
readings are taken from the respective Common of Saints.  

155. As far as possible, each passage read keeps to a certain unity. In order 
therefore to strike a balance in length (otherwise difficult to achieve in view 
of the different literary genres of the books), some verses are occasionally 
omitted, though omissions are always noted. But it is permissible and 
commendable to read the complete passage from an approved text.  

C. SHORT READINGS  

156. The short readings or "chapters" (capitula) are referred to in no. 45,
which describes their importance in the liturgy of the hours. They have been 
chosen to give clear and concise expression to a theme or an exhortation. Care 
has also been taken to ensure variety.  

157. Accordingly, four weekly series of short readings have been composed for 
Ordinary Time. They are incorporated into the psalter in such a way that the 
reading changes during the four weeks. There are also weekly series for the 
seasons of Advent, Christmas, Lent, and Easter, In addition there are proper 
short readings for solemnities, feasts, and some memorials, as well as a 
one-week series for night prayer.  

158. The following determined the choice of short readings:  

a. in accordance with tradition, exclusion of the Gospels;  

b. respect for the special character of Sunday, or even of Friday, and of the 
individual hours;  

c. use only of the New Testament for the readings at evening prayer, following 
as they do a New Testament canticle.  

VII. READINGS FROM THE FATHERS AND CHURCH WRITERS  

159. In keeping with the tradition of the Roman Church the office of readings 
has, after the biblical reading, a reading from the Fathers or church writers, 
with a responsory, unless there is to be a reading relating to a saint (see nos. 
228-239).  

160. Texts for this reading are given from the writings of the Fathers and 
doctors of the Church and from other ecclesiastical writers of the Eastern and 
Western Church. Pride of place is given to the Fathers because of their 
distinctive authority in the Church.  

161. In addition to the readings that The Liturgy of the Hours assigns to each 
day, the optional lectionary supplies a larger collection, in order that the 
treasures of the Church's tradition may be more widely available to those who 
pray the liturgy of the hours. Everyone is free to take the second reading 
either from The Liturgy of the Hours or from the optional lectionary.  

162. Further the conferences of bishops may prepare additional texts adapted to 
the traditions and culture of their own region, [8] for inclusion in the 
optional lectionary as a supplement. These texts are to be taken from the works 
of Catholic writers, outstanding for their teaching and holiness of life.  

163. The purpose of the second reading is principally to provide for meditation 
on the word of God as received by the Church in its tradition. The Church has 
always been convinced of the need to teach the word of God authentically to 
believers, so that "the line of interpretation regarding the prophets and 
apostles may be guided by an ecclesial and catholic understanding." [9]             

164. By constant use of the writings handed down by the universal tradition of 
the Church, those who read them are led to a deeper reflection on sacred 
Scripture and to a relish and love for it. The writings of the Fathers are an 
outstanding witness to the contemplation of the word of God over the centuries 
by the Bride of the incarnate Word: the Church, "possessing the counsel and
spirit of its Bridegroom and God," [10] is always seeking to attain a more 
profound understanding of the sacred Scriptures.  

165. The reading of the Fathers leads Christians to an understanding also of the 
liturgical seasons and feasts. In addition, it gives them access to the 
priceless spiritual treasures that form the unique patrimony of the Church and 
provide a firm foundation for the spiritual life and a rich source for 
increasing devotion. Preachers of God's word also have at hand each day superb 
examples of sacred preaching.  

VIII. READINGS IN HONOR OF SAINTS  

166. The "hagiographical" readings or readings in honor of saints are either 
texts from a Father of the Church or another ecclesiastical writer, referring 
specifically or rightly applicable to the saint being commemorated, or the 
readings are texts from the saint's own writings, or are biographical.  

167. Those who compose particular propers for saints must ensure historical 
accuracy [11] as well as genuine spiritual benefit for those who will read or 
hear the readings about the saints. Anything that merely excites amazement 
should be carefully avoided. Emphasis should be given to the individual 
spiritual characteristics of the saints, in a way suited to modern conditions; 
stress should also be laid on their contribution to the life and spirituality of 
the Church.  

168. A short biographical note, simply giving historical facts and a brief 
sketch of the saint's life, is provided at the head of the reading. This is for 
information only and is not for reading aloud.  

IX RESPONSORIES  

169. Its responsory follows the biblical reading in the office of readings. The 
text of this responsory has been drawn from traditional sources or freshly 
composed, in order to throw new light on the passage just read, put it in the 
context of the history of salvation, lead from the Old Testament to the New, 
turn what has been read into prayer and contemplation, or provide pleasant 
variety by its poetic beauty.  

170. A pertinent responsory also follows the second reading. It is less closely 
linked with the text of the reading, however, and thus makes for a greater 
freedom in meditation.  

171. The responsories and the portions to be repeated even in private recitation 
therefore retain their value. The customary reprise of the whole responsory may 
be omitted when the office is not being sung, unless the sense requires this 
repetition.  

172. In a similar but simpler way, the responsory at morning prayer, evening 
prayer, and night prayer (see nos. 49 and 89), and the verse at daytime prayer, 
are linked to the short reading as a kind of acclamation, enabling God's word to 
enter more deeply into the mind and heart of the one listening or reading.  

X. HYMNS AND OTHER NONBIBLICAL SONGS  

173. A very ancient tradition gives hymns the place in the office that they 
still retain. [12] By their mystical and poetic character they are specifically 
designed for God's praise. But they also are an element for the people; in fact 
more often than the other parts of  the office the hymns bring out the proper
theme of individual hours or feasts and incline and draw the spirit to a devout 
celebration. The beauty of their language often adds to this power. Furthermore, 
in the office hymns are the main poetic element created by the Church.  

174. A hymn follows the traditional rule of ending with a doxology, usually 
addressed to the same divine person as the hymn itself.  

175. In the office for Ordinary Time, to ensure variety, a twofold cycle of 
hymns is given for each hour, for use in alternate weeks.  

176. In addition, a twofold cycle of hymns has been introduced into the office 
of readings for Ordinary Time, one for use at night and the other for use during 
the day.  

177. New hymns can be set to traditional melodies of the same rhythm and meter.  

178. For vernacular celebration, the conferences of bishops may adapt the Latin 
hymns to suit the character of their own language and introduce fresh 
compositions, [13] provided these are in complete harmony with the spirit of the 
hour, season, or feast. Great care must be taken not to allow popular songs that 
have no artistic merit and are not in keeping with the dignity of the liturgy.

XI. INTERCESSIONS, LORD'S PRAYER, AND CONCLUDING PRAYER  

A. THE PRAYERS OR INTERCESSIONS AT MORNING PRAYER AND EVENING PRAYER  

179. The liturgy of the hours is a celebration in praise of God. Yet Jewish and
Christian tradition does not separate prayer of petition from praise of God; 
often enough, praise turns somehow to petition. The Apostle Paul exhorts us to 
offer prayers, petitions, intercessions, and thanksgiving for all: for kings and 
all in authority, so that we may be able to live quiet and peaceful lives in all 
reverence and decency, for this is good and acceptable before God our Savior, 
who wishes all to be saved and to come to the knowledge of the truth" (I Tm 
2:1-4). The Fathers of the Church frequently explained this as an exhortation to 
offer prayer in the morning and in the evening. [14]   

180. The general intercessions, restored in the Mass of the Roman Rite, have 
their place also at evening prayer, though in a different fashion, as will be 
explained later.   

181. Since traditionally morning prayer puts the whole day in God's hands, there 
are invocations at morning prayer for the purpose of commending or consecrating 
the day to God.   

182. The word preces covers both the intercessions at evening prayer and the 
invocations for dedicating the day to God at morning prayer.   

183. In the interest of variety and especially of giving fuller expression to 
the many needs of the Church and of all people in relation to different states 
of life, groups, persons, circumstances, and seasons, different intercessory 
formularies are given for each day of the four-week psalter in Ordinary Time and 
for the special seasons of the liturgical year, as well as for certain feasts.   

184. In addition, the conferences of bishops have the right to adapt the 
formularies given in the book of the liturgy of the hours and also to approve 
new ones, [15] in accordance with the norms that follow.
185. As in the Lord's Prayer, petitions should be linked with praise of God and 
acknowledgment of his glory or with a reference to the history of salvation.   

186. In the intercessions at evening prayer the last intention is always for the 
dead.   

187. Since the liturgy of the hours is above all the prayer of the whole Church 
for the whole Church, indeed for the salvation of the whole world, [16] 
universal intentions should take precedence over all others, namely, for: the 
Church and its ministers; secular authorities; the poor, the sick, and the 
sorrowful; the needs of the whole world, that is, peace and other intentions of 
this kind.   

188. It is permissible, however, to include particular intentions at both 
morning prayer and evening prayer.   

189. The intercessions in the office are so arranged that they can be adapted 
for celebration with a congregation or in a small community or for private 
recitation.   

190. The intercessions in a celebration with a congregation or in common are 
thus introduced by a brief invitation, given by the priest or minister and 
designating the single response that the congregation is to repeat after each 
petition.   

191. Further, the intentions are phrased as direct addresses to God and thus are 
suitable for both common celebration and private recitation.
 
192. Each intention consists of two parts; the second may be used as an 
alternative response.   

193. Different methods can therefore be used for the intercessions. The priest 
or minister may say both parts of the intention and the congregation respond 
with a uniform response or a silent pause, or the priest or minister may say 
only the first part of the intention and the congregation respond with the 
second part.   

B. LORD'S PRAYER   

194. In accord with ancient tradition, the Lord's Prayer has a place suited to 
its dignity, namely, after the intercessions at morning prayer and evening 
prayer, the hours most often celebrated with the people.   

195. Henceforth, therefore, the Lord's Prayer will be said with solemnity on 
three occasions during the day: at Mass, at morning prayer, and at evening 
prayer.   

196. The Lord's Prayer is said by all after a brief introduction, if this seems 
opportune.   

C. CONCLUDING PRAYER   

197. The concluding prayer at the end marks the completion of an entire hour. In 
a celebration in public and with a congregation, it belongs by tradition to a
priest or deacon to say this prayer. [17]   

198. In the office of readings, this prayer is as a rule the prayer proper to 
the day. At night prayer, the prayer is always the prayer given in the psalter 
for that hour.   

199. The concluding prayer at morning prayer and evening prayer is taken from 
the proper on Sundays, on the weekdays of the seasons of Advent, Christmas, 
Lent, and Easter, and on solemnities, feasts, and memorials. On weekdays in 
Ordinary Time the prayer is the one given in the four-week psalter to express 
the character of these two hours.   

200. The concluding prayer at daytime prayer is taken from the proper on 
Sundays, on the weekdays of the seasons of Advent, Christmas, Lent, and Easter, 
and on solemnities and feasts. On other days the prayers are those that express 
the character of the particular hour. These are given in the four-week psalter.

XII. SACRED SILENCE   

201. It is a general principle that care should be taken in liturgical services 
to see that "at the proper times all observe a reverent silence." [18] An 
opportunity for silence should therefore be provided in the celebration of the 
liturgy of the hours.   

202. In order to receive in our hearts the full sound of the voice of the Holy 
Spirit and to unite our personal prayer more closely with the word of God and 
the public voice of the Church, it is permissible, as occasion offers and 
prudence suggests, to have an interval of silence. It may come either after the 
repetition of the antiphon at the end of the psalm, in the traditional way, 
especially if the psalm-prayer is to be said after the pause (see no. 112), or 
after the short or longer readings, either before or after the responsory.   

Care must be taken to avoid the kind of silence that would disturb the structure
of the office or annoy and weary those taking part.   

203. In individual recitation there is even greater freedom to pause in 
meditation on some text that moves the spirit; the office does not on this 
account lose its public character.

CHAPTER IV   
VARIOUS CELEBRATIONS THROUGHOUT THE YEAR   

I. MYSTERIES OF THE LORD   

A. SUNDAY   

204. The office of Sunday begins with evening prayer I, which is taken entirely 
from the four-week psalter, except those parts that are marked as proper.   

205. When a feast of the Lord is celebrated on Sunday, it has a proper evening 
prayer I.   

206. The way to celebrate Sunday vigils, as circumstances suggest, has been 
discussed in no. 73.   

207. It is of great advantage to celebrate, when possible, at least evening 
prayer with the people, in keeping with a very ancient tradition. [1]   

B. EASTER TRIDUUM   

208. For the Easter triduum the office is celebrated in the way set forth in the 
Proper of Seasons.   

209. Those who take part in the evening Mass of the Lord's Supper or the 
celebration of the Lord's passion on Good Friday do not say evening prayer on 
either day.   

210. On Good Friday and Holy Saturday the office of readings should be 
celebrated publicly with the people before morning prayer, as far as this is 
possible.   

211. Night prayer for Holy Saturday is said only by those who are not present at 
the Easter Vigil.   

212. The Easter Vigil takes the place of the office of readings. Those not 
present at the solemn celebration of the Vigil should therefore read at least 
four of its readings with the chants and prayers. It is desirable that these be 
the readings from Exodus, Ezekiel, St. Paul, and from the Gospel. The Te Deum 
follows, then the prayer of the day.   

213. Morning prayer for Easter Sunday is said by all. It is fitting that evening 
prayer be celebrated in a more solemn way to mark the ending of so holy a day 
and to commemorate the occasions when the Lord showed himself to his disciples. 
Great care should be taken to maintain, where it exists, the particular 
tradition of celebrating evening prayer on Easter Sunday in honor of baptism. 
During this there is a procession to the font as the psalms are being sung.   

C. EASTER SEASON   

214. The liturgy of the hours takes on a paschal character from the acclamation, 
Alleluia that concludes most antiphons (see no. 120), from the hymns, antiphons, 
and special intercessions, and from the proper readings assigned to each hour.   

D. CHRISTMAS SEASON   

215. On Christmas eve it is fitting that by means of the office of readings, a 
solemn vigil be celebrated before Mass. Night prayer is not said by those 
present at this vigil.   

216. Morning prayer on Christmas Day is said as a rule before the Mass at Dawn.   

E. OTHER SOLEMNITIES AND FEASTS OF THE LORD   

217. In arranging the office for solemnities and feasts of the Lord, what is 
said in nos. 225-233 should be observed, with any necessary changes.   

II. THE SAINTS   

218. The celebrations of the saints are arranged so that they do not take 
precedence over those feast days and special seasons that commemorate the
mysteries of salvation. [2] Nor are they allowed to break up the sequence of 
psalms and biblical readings or to give rise to undue repetitions. At the same 
time, the plan makes proper provision for the rightful honoring of the 
individual saints. These principles form the basis for the reform of the 
calendar, carried out by order of Vatican Council 11, and for the plan for 
celebrating the saints in the liturgy of the hours that is described in the 
following paragraphs.   

219. Celebrations in honor of the saints are either solemnities, feasts, or 
memorials.   

220. Memorials are either obligatory memorials or, when not so classified, 
optional memorials. In deciding on the merits of celebrating an optional 
memorial in an office to be celebrated with the people or in common, account 
should be taken of the general good or of the genuine devotion of the 
congregation, not simply that of the person presiding.   

221. When more than one optional memorial falls on the same day, only one may be  
celebrated; the rest are omitted.   

222. Only solemnities are transferred, in accordance with the rubrics.   

223. The norms that follow apply to the saints entered in the General Roman 
Calendar and to those with a place in particular calendars.   

224. Where proper parts are not given, they are supplied from the respective 
Common of Saints.

1. ARRANGEMENT OF THE OFFICE FOR SOLEMNITIES   

225. Solemnities have an evening prayer I on the preceding day.
 
226. At evening prayer I and 11, the hymn, the antiphons, the short reading with 
its responsory, and the concluding prayer are proper. Where anything proper is 
missing, it is supplied from the common.   

In keeping with an ancient tradition, at evening prayer I both psalms are as a 
rule taken from the Laudate Psalms (Ps 113, 117, 135, 146, 147 A, 147 B). The 
New Testament canticle is noted in its appropriate place. At evening prayer II 
the psalms and canticles are proper; the intercessions are either proper or from 
the common.   

227. At morning prayer, the hymn, the antiphons, the short reading with its 
responsory, and the concluding prayer are proper. Where anything proper is 
missing, it is supplied from the common. The psalms are to be taken from the 
Sunday of Week I of the four-week psalter; the intercessions are either proper 
or from the common.   

228. In the office of readings, everything is proper: the hymn, the antiphons 
and psalms, the readings and the responsories. The first reading is from 
Scripture; the second is about the saint. In the case of a saint with a purely 
local cult and without special texts even in the local proper, everything is 
taken from the common.   

At the end of the office of readings the Te Deum and the proper prayer are said.   

229. At daytime prayer, the hymn of the weekday is used, unless other directions 
are given. The psalms are from the Gradual Psalms with a proper antiphon. On 
Sundays the psalms are taken from the Sunday of Week I of the four-week psalter 
and the short reading and concluding prayer are proper. But on certain 
solemnities of the Lord there are special psalms.   

230. At night prayer, everything is said as on Sundays, after evening prayer I 
and II respectively.   

2. ARRANGEMENT OF THE OFFICE FOR FEASTS   

231. Feasts have no evening prayer 1, except those feasts of the Lord that fall 
on a Sunday. At the office of readings, at morning prayer, and at evening 
prayer, all is done as on solemnities.
232. At daytime prayer, the hymn of the weekday is used. The weekday psalms with 
their antiphons are said, unless a special reason or tradition requires a proper 
antiphon; this will be indicated as the case occurs. The reading and concluding 
prayer are proper.   

233. Night prayer is said as on ordinary days.   

3. ARRANGEMENT OF THE OFFICE FOR MEMORIALS   

234. In the arrangement of the office there is no difference between obligatory 
and optional memorials, except in the case of optional memorials falling during 
privileged seasons.   

A. MEMORIALS DURING ORDINARY TIME   

235. In the office of readings, at morning prayer, and at evening prayer:   

a. the psalms and their antiphons are taken from the current week and day, 
unless there are proper antiphons or proper psalms, which is indicated as the 
case occurs;   

b. the antiphon at the invitatory, the hymn, the short reading, the antiphons at 
the Canticles of Zechariah and of Mary, and the intercessions must be those of 
the saint if these are given in the proper; otherwise, they are taken either
from the common or from the current week and day;   

c. the concluding prayer from the office of the saint is to be said;   

d. in the office of readings, the Scripture reading with its responsory is from 
the current cycle. The second reading is about the saint, with a proper 
responsory or one taken from the common; if there is no proper reading, the 
patristic reading for the day is used. The Te Deum is not said.   

236. At daytime prayer and night prayer, all is from the weekday and nothing is 
from the office of the saint.   

B. MEMORIALS DURING PRIVILEGED SEASONS   

237. On Sundays, solemnities, and feasts, on Ash Wednesday, during Holy Week, 
and during the octave of Easter, memorials that happen to fall on these days are 
disregarded.   

238. On the weekdays from 17 to 24 December, during the octave of Christmas, and 
on the weekdays of Lent, no obligatory memorials are celebrated, even in 
particular calendars. When any happen to fall during Lent in a given year, they 
are treated as optional memorials.   

239. During privileged seasons, if it is desired to celebrate the office of a 
saint on a day assigned to his or her memorial:   

a. in the office of readings, after the patristic reading (with its responsory) 
from the Proper of Seasons, a proper reading about the saint (with its 
responsory) may follow, with the concluding prayer of the saint;   

b. at morning prayer and evening prayer, the ending of the concluding prayer may 
be omitted and the saint's antiphon (from the proper or common) and prayer may 
be added.   

C. MEMORIAL OF THE BLESSED VIRGIN MARY ON SATURDAY   

240. On Saturdays in Ordinary Time, when optional memorials are permitted, an 
optional memorial of the Blessed Virgin Mary may be celebrated in the same way 
as other memorials, with its own proper reading.

III. CALENDAR AND OPTION TO CHOOSE AN OFFICE OR PART OF AN OFFICE   

A. CALENDAR To BE FOLLOWED   

241. The office in choir and in common is to be celebrated according to the 
proper calendar of the diocese, of the religious family, or of the individual 
churches. [3] Members of religious institutes join with the community of the 
local Church in celebrating the dedication of the cathedral and the feasts of 
the principal patrons of the place and of the wider geographical region in which 
they live. [4]   

242. When clerics or religious who are obliged under any title to pray the 
divine office join in an office celebrated in common according to a calendar or 
rite different from their own, they fulfill their obligation in respect to the 
part of the office at which they are present.
 
243. In private celebration, the calendar of the place or the person's own 
calendar may be followed, except on proper solemnities and on proper feasts. [5]   

B. OPTION TO CHOOSE AN OFFICE   

244. On weekdays when an optional memorial is permitted, for a good reason the 
office of a saint listed on that day in the Roman Martyrology, or in an approved 
appendix to it, may be celebrated in the same way as other memorials (see nos. 
234-239).   

245. For a public cause or out of devotion, except on solemnities, the Sundays 
of the seasons of Advent, Lent, and Easter, Ash Wednesday, Holy Week, the octave 
of Easter, and 2 November, a votive office may be celebrated, in whole or in 
part: for example, on the occasion of a pilgrimage, a local feast, or the 
external solemnity of a saint.   

C. OPTION TO CHOOSE TEXTS   

246. In certain particular cases there is an option to choose texts different 
from those given for the day, provided there is no distortion of the general 
arrangement of each hour and the rules that follow are respected.   

247. In the office for Sundays, solemnities, feasts of the Lord listed in the 
General Calendar, the weekdays of Lent and Holy Week, the days within the 
octaves of Easter and Christmas, and the weekdays from 17 to 24 December 
inclusive, it is never permissible to change the formularies that are proper or 
adapted to the celebration, such as antiphons, hymns, readings, responsories, 
prayers, and very often also the psalms.   

In place of the Sunday psalms of the current week, there is an option to 
substitute the Sunday psalms of a different week, and, in the case of an office 
celebrated with a congregation, even other psalms especially chosen to lead the 
people step by step to an understanding of the psalms.   

248. In the office of readings, the current cycle of sacred Scripture must 
always be respected. The Church's intent that "a more representative portion of 
the holy Scriptures will be read to the people in the course of a prescribed 
number of years" [6] applies also to the divine office.   

Therefore the cycle of readings from Scripture that is provided in the office of 
readings must not be set aside during the seasons of Advent, Christmas, Lent, 
and Easter. 'During Ordinary Time, however, on a particular day or for a few 
days in succession, it is permissible, for a good reason, to choose readings 
from those provided on other days or even other biblical readings, for example, 
on the occasion of retreats, pastoral gatherings, prayers for Christian unity,
or other such events.   

249. When the continuous reading is interrupted because of a solemnity or feast 
or special celebration, it is allowed during the same week, taking into account 
the readings for the whole week, either to combine the parts omitted with others
or to decide which of the texts are to be preferred.   

250. The office of readings also offers the option to choose, with a good 
reason, another reading from the same season, taken from The Liturgy of the 
Hours or the optional lectionary (no. 161), in preference to the second reading 
appointed for the day. On weekdays in Ordinary Time and, if it seems opportune, 
even in the seasons of Advent, Christmas, Lent, and Easter, the choice is open 
for a semicontinuous reading of the work of a Father of the Church, in harmony 
with the biblical and liturgical context.   

251. The readings, prayers, songs, and intercessions appointed for the weekdays 
of a particular season may be used on other weekdays of the same season.   

252. Everyone should be concerned to respect the complete cycle of the four-week 
psalter. [7] Still, for spiritual or pastoral advantage, the psalms appointed 
for a particular day may be replaced with others from the same hour of a 
different day. There are also circumstances occasionally arising when it is 
permissible to choose suitable psalms and other texts in the way done for a 
votive office.

CHAPTER V   
RITES FOR CELEBRATION IN COMMON   

I. OFFICES TO BE CARRIED OUT   

253. In the celebration of the liturgy of the hours, as in all other liturgical 
services, "each one, minister or layperson, who has an office to perform, should 
do all of, but only, those parts which pertain to that office by the nature of 
the rite and the principles of liturgy." [1]   

254. When a bishop presides, especially in the cathedral, he should be attended 
by his college of priests and by ministers and the people should take a full and 
active part. A priest or deacon should normally preside at every celebration 
with a congregation and ministers should also be present.   

255. The priest or deacon who presides at a celebration may wear a stole over 
the alb or surplice; a priest may also wear a cope. On greater solemnities the
wearing of the cope by many priests or of the dalmatic by many deacons is 
permitted.   

256. It belongs to the presiding priest or deacon, at the chair, to open the 
celebration with the introductory verse, begin the Lord's Prayer, say the 
concluding prayer, greet the people, bless them, and dismiss them.   

257. Either the priest or a minister may lead the intercessions.   

258. In the absence of a priest or deacon, the one who presides at the office is 
only one among equals and does not enter the sanctuary or greet and bless the 
people.   

259. Those who act as readers, standing in a convenient place, read either the 
long readings or the short readings.   

260, A cantor or cantors should intone the antiphons, psalms, and other chants.
 
With regard to the psalmody, the directions of nos. 121-125 should be followed.   

261. During the gospel canticle at morning prayer and evening prayer there may 
be an incensation of the altar, then of the priest and congregation.
 
262. The choral obligation applies to the community, not to the place of 
celebration, which need not be a church, especially in the case of those hours  
that are celebrated without solemnity.   

263. All taking part stand during:   

a. the introduction to the office and the introductory verses of each hour;   

b. the hymn;   

c. the gospel canticle;   

d. the intercessions, the Lord's Prayer, and the concluding prayer.   

264. All sit to listen to the readings, except the gospel.   

265. The assembly either sits or stands, depending on custom, while the psalms 
and other canticles (with their antiphons) are being said.
266. All make the sign of the cross, from forehead to breast and from left 
shoulder to right, at:   

a. the beginning of the hours, when God, come to my assistance is being said;   

b. the beginning of the gospel, the Canticles of Zechariah, of Mary, and of
Simeon.   

The sign of the cross is made on the mouth at the beginning of the invitatory, 
at Lord, open my lips.

II. SINGING IN THE OFFICE   

267. In the rubrics and norms of this Instruction, the words "say .. .. recite," 
etc., are to be understood to refer to either singing or recitation, in the 
light of the principles that follow.   

268. "The sung celebration of the divine office is more in keeping with the 
nature of this prayer and a mark of both higher solemnity and closer union of 
hearts in offering praise to God. . . . Therefore the singing of the office is 
earnestly recommended to those who carry out the office in choir or in common." 
[2]   

269. The declarations of Vatican Council II on liturgical singing apply to all 
liturgical services but in a special way to the liturgy of the hours. [3] Though 
every part of it has been revised in such a way that all may be fruitfully 
recited even by individuals, many of these parts are lyrical in form and do not 
yield their fuller meaning unless they are sung, especially the psalms, 
canticles, hymns, and responsories.   

270. Hence, in celebrating the liturgy singing is not to be regarded as an 
embellishment superimposed on prayer; rather, it wells up from the depths of a 
soul intent on prayer and the praise of God and reveals in a full and complete 
way the community nature of Christian worship.   

Christian communities of all kinds seeking to use this form of prayer as 
frequently as possible are to be commended. Clerics and religious, as well as 
all the people of God, must be trained by suitable catechesis and practice to 
join together in singing the hours in a spirit of joy, especially on Sundays and 
holydays. But it is no easy task to sing the entire office; nor is the Church's 
praise to be considered either by origin or by nature the exclusive possession 
of clerics and monks but the property of the whole Christian community. 
Therefore several principles must be kept simultaneously in mind if the sung 
celebration of the liturgy of the hours is to be performed correctly and to 
stand out in its true nature and splendor.   

271. It is particularly appropriate that there be singing at least on Sundays 
and holydays, so that the different degrees of solemnity will thus come to be 
recognized.   

272. It is the same with the hours: all are not of equal importance; thus it is 
desirable that those that are the true hinges of the office, that is, morning 
prayer and evening prayer, should receive greater prominence through the use of 
singing.   

273. A celebration with singing throughout is commendable, provided it has 
artistic and spiritual excellence; but it may be useful on occasion to apply the 
principle of "progressive solemnity." There are practical reasons for this, as 
well as the fact that in this way the various elements of liturgical celebration 
are not treated indiscriminately, but each can again be given its connatural 
meaning and genuine function. The liturgy of the hours is then not seen as a 
beautiful memorial of the past demanding intact preservation as an object of 
admiration; rather it is seen as open to constantly new forms of life and growth 
and to being the unmistakable sign of a community's vibrant vitality.   

The principle of "progressive solemnity" therefore is one that recognizes 
several intermediate stages between singing the office in full and just reciting 
all the parts. Its application offers the possibility of a rich and pleasing 
variety. The criteria are the particular day or hour being celebrated, the 
character of the individual elements comprising the office, the size and 
composition of the community, as well as the number of singers available in the 
circumstances.   

With this increased range of variation, it is possible for the public praise of 
the Church to be sung more frequently than formerly and to be adapted in a 
variety of ways to different circumstances. There is also great hope that new 
ways and expressions of public worship may be found for our own age, as has 
clearly always happened in the life of the Church.   

274. For liturgical celebrations sung in Latin, Gregorian chant, as the music 
proper to the Roman liturgy, should have pride of place, all other things being 
equal. [4] Nevertheless, "the Church does not exclude any type of sacred music 
from liturgical services as long as the music matches the spirit of the service 
itself and the character of the individual parts and is not a hindrance to the 
required active participation of the people." [5] At a sung office, if a melody 
is not available for the given antiphon, another antiphon should be taken from 
those in the repertoire, provided it is suitable in terms of nos. 113 and 
121-125.   

275. Since the liturgy of the hours may be celebrated in the vernacular, 
"appropriate measures are to be taken to prepare melodies for use in the 
vernacular singing of the divine office." [6]   

276. But it is permissible to sing the various parts in different languages at 
one and the same celebration. [7]
 
277. The decision on which parts to choose for singing follows from the 
authentic structure of a liturgical celebration. This demands that the 
significance and function of each part and of singing should be fully respected. 
Some parts by their nature call for singing:  [8] in particular, acclamations, 
responses to the greetings of priest and ministers, responses in litanies, also 
antiphons and psalms, the verses and reprises in responsories, hymns and 
canticles. [9]   

278. Clearly the psalms are closely bound up with music (see nos. 103-120), as 
both Jewish and Christian tradition confirm. In fact a complete understanding of 
many of the psalms is greatly assisted by singing them or at least not losing 
sight of their poetic and musical character. Accordingly, whenever possible 
singing the psalms should have preference, at least for the major days and hours 
and in view of the character of the psalms themselves.   

279. The different ways of reciting the psalms have been described in nos. 
121-123. Varying these ways should depend not so much on external circumstances 
as on the different genres of the psalms to be recited in the same celebration. 
Thus the wisdom psalms and the narrative psalms are perhaps better listened to, 
whereas psalms of praise and thanksgiving are of their nature designed for 
singing in common. The main consideration is to ensure that the celebration is 
not too inflexible or elaborate nor concerned merely with formal observance of 
rules, but that it matches the reality of what is celebrated. The primary aim 
must be to inspire hearts with a desire for genuine prayer and to show that the 
celebration of God's praise is a thing of joy (see Ps 147).   

280. Even when the hours are recited, hymns can nourish prayer, provided they 
have doctrinal and literary excellence; but of their nature they are designed 
for singing and so, as far as possible, at a celebration in common they should 
be sung.   

281. The short responsory after the reading at morning prayer and evening prayer 
(see no. 49) is of its nature designed for singing and indeed for congregational 
singing.   

282. The responsories following the readings in the office of readings by their 
very nature and function also call for their being sung. In the plan of the 
office, however, they are composed in such a way that they retain their power 
even in individual and private recitation. Responsories set to simpler melodies 
can be sung more frequently than those responsories drawn from the traditional 
liturgical books.   

283. The longer readings and the short readings are not of themselves designed 
for singing. When they are proclaimed, great care should be taken that the 
reading is dignified, clear, and distinct and that it is really audible and 
fully intelligible for all. The only acceptable melody for a reading is 
therefore one that best ensures the hearing of the words and the understanding 
of the text.   

284. Texts that are said only by the person presiding, such as the concluding 
prayer, can be sung gracefully and appropriately, especially in Latin. This, 
however, will be more difficult in some languages, unless singing makes the 
texts more clearly audible for all.
