Chapter I. General Principles for the Restoration and Promotion of the Sacred Liturgy

Part 1. The Nature of the Sacred Liturgy and its Importance in the Church's life.

5.God who "wills that all men be saved and come to the knowledge of the truth" (1 Tim. 2:4), "who in many and various ways spoke in times past to the fathers by the prophets" (Heb. 1:1), when the fullness of time had come sent His Son, the Word made flesh, anointed by the Holy Spirit, to preach the gospel to the poor, to heal the contrite of heart, [8] to be a "bodily and spiritual medicine," [9] the Mediator between God and man. [10] For His humanity, united with the person of the Word, was the instrument of our salvation. Therefore in Christ "the perfect achievement of our reconciliation came forth, and the fullness of divine worship was given to us." [11]

The wonderful works of God among the people of the Old Testament were but a prelude to the work of Christ the Lord in redeeming mankind and giving perfect glory to God. He achieved His task principally by the paschal mystery of His blessed passion, resurrection from the dead, and glorious ascension, whereby "dying, he destroyed our death and, rising, he restored our life." [12] For it was from the side of Christ as He slept the sleep of death upon the cross that there came forth "the wondrous sacrament of the whole Church." [13]

6.Just as Christ was sent by the Father, so also He sent the apostles, filled with the Holy Spirit. This He did that, by preaching the gospel to every creature, [14] they might proclaim that the Son of God, by His death and resurrection, had freed us from thee power of Satan [15] and from death, and brought us into the kingdom of His Father. His purpose also was that they might accomplish the work of salvation which they had proclaimed, by means of sacrifice and sacraments, around which the entire liturgical life revolves. Thus by baptism men are plunged into the paschal mystery of Christ: they die with Him, are buried with Him, and rise with Him; [16] Abba, Father" (Rom. 8:15), and thus become true adorers whom the Father seeks. [17] In like manner, as often as they eat the supper of the Lord they proclaim thee death of the Lord until He comes. [18] For that reason, on the very day of Pentecost, when the Church appeared before the world, "those who received the word" of Peter "were baptized." And "they continued steadfastly in the teaching of the apostles and in the communion of the breaking of bread and in prayers . . . praising God and being in favor with all the people" (Acts 2:41-47). From that time onwards thee Church has never failed to come together to celebrate the paschal mystery: reading those things "which were in all the scriptures concerning him" (Luke 24:27), celebrating the eucharist in which "the victory and triumph of his death are again made present," [19] and at the same time giving thanks "to God for his unspeakable gift" (2 Cor. 9:15) in Christ Jesus, "in praise of his glory" (Eph. 1:12), through the power of the Holy Spirit.

7.To accomplish so great a work, Christ is always present in His Church, especially in her liturgical celebrations. He is present in the sacrifice of the Mass, not only in the person of His minister, "the same now offering, through the ministry of priests, who formerly offered himself on the cross," [20] but especially under the eucharistic species. By His power He is present in the sacraments, so that when a man baptizes it is really Christ Himself who baptizes. [21] He is present in His word, since it is He Himself who speaks when the holy scriptures are read in the Church. He is present, lastly, when the Church prays and sings, for He promised: "Where two or three are gathered together in my name, there am I in thee midst of them" (Matt. 18:20).

Christ indeed always associates the Church with Himself in this great work wherein God is perfectly glorified and men are sanctified. The Church is His beloved Bride who calls to her Lord, and through Him offers worship to the Eternal Father.

Rightly, then, the liturgy is considered as an exercise of the priestly office of Jesus Christ. In the liturgy the sanctification of thee man is signified by signs perceptible to the senses, and is effected in a way which corresponds with each of these signs; in the liturgy the whole public worship is performed by the Mystical Body of Jesus Christ, that is, by the Head and His members.

From this it follows that every liturgical celebration, because it is an action of Christ the priest and of His Body which is the Church, is a sacred action surpassing all others; no other action of the Church can equal its efficacy by the same title and to the same degree.

8.In the earthly liturgy we take part in a foretaste of that heavenly liturgy which is celebrated in the holy city of  Jerusalem toward which we journey as pilgrims, where Christ is sitting at the right hand of God, a minister of the holies and of the true tabernacle; [22] we sing a hymn to the Lord's glory with all the warriors of the heavenly army; venerating the memory of the saints, we hope for some part and fellowship with them; we eagerly await the Savior, Our Lord Jesus Christ, until He, our life, shall appear and we too will appear with Him in glory. [23]

9.The sacred liturgy does not exhaust the entire activity of the Church. Before men can come to the liturgy they must be called to faith and to conversion: "How then are they to call upon him in whom they have not yet believed? But how are they to believe in him whom they have not heard? And how are they to hear if no one preaches? And how are men to preach unless they be sent?" (Rom. 10:14-15).

Therefore the Church announces the good tidings of salvation to those who do not believe, so that all men may know the true God and Jesus Christ whom He has sent, and may be converted from their ways, doing penance. [24] To believers also the Church must ever preach faith and penance, she must prepare them for the sacraments, teach them to observe all that Christ has commanded, [25] and invite them to all the works of charity, piety, and the apostolate. For all these works make it clear that Christ's faithful, though not of this world, are to be the light of the world and to glorify the Father before men.

10.Nevertheless the liturgy is the summit toward which the activity of the Church is directed; at the same time it is the font from which all her power flows. For the aim and object of apostolic works is that all who are made sons of God by faith and baptism should come together to praise God in the midst of His Church, to take part in the sacrifice, and to eat the Lord's supper.

The liturgy in its turn moves the faithful, filled with "the paschal sacraments," to be "one in holiness;" [26] it prays that "they may hold fast in their lives to what they have grasped by their faith;" [27] the renewal in the eucharist of the covenant between the Lord and man draws the faithful into the compelling love of Christ and sets them on fir. From the liturgy, therefore, and especially from the eucharist, as from a font, grace is poured forth upon us; and the sanctification of men in Christ and the glorification of God, to which all other activities of the Church are directed as toward their end, is achieved in the most effacious possible way.

11.But in order that the liturgy may be able to produce its full effects, it is necessary that the faithful come to it with proper dispositions, that their minds should be attuned to their voices, and that they should cooperate with divine grace lest they receive it in vain. [28] Pastors of souls must therefore realize that, when the liturgy is celebrated, something more is required than the mere observation of the laws governing valid and licit celebration; it is their duty also to ensure that the faithful take part fully aware of what they are doing, actively engaged in the rite, and enriched by its effects.

12.The spiritual life, however, is not limited solely to participation in the liturgy. The Christian is indeed called to pray with his brethren, but he must also enter into his chamber to pray to the Father, in secret; [29] yet more, according to the teaching of the Apostle, he should pray without ceasing. [30] We learn from the same Apostle that we must always bear about in our body the dying of Jesus, so that the life also of Jesus may be made manifest in our bodily frame. [31] This is why we ask the Lord in the sacrifice of the Mass that, "receiving the offering of the spiritual victim," he may fashion us for himself "as an eternal gift." [32]

13.Popular devotions of the Christian people are to bee highly commended, provided they accord with the laws and norms of the Church, above all when they are ordered by the Apostolic See.

Devotions proper to individual Churches also have a special dignity if they are undertaken by mandate of the bishops according to customs or books lawfully approved.

But these devotions should be so drawn up that they harmonize with the liturgical seasons, accord with the sacred liturgy, are in some fashion derived from it, and lead the people to it, since, in fact, the liturgy by its very nature far surpasses any of them.

Part 2. The Promotion of Liturgical Instruction and Active Participation

14.Mother Church earnestly desires that all the faithful should be led to that full, conscious, and active participation in liturgical celebrations which is demanded by the very nature of the liturgy. Such participation by the Christian people as "a chosen race, a royal priesthood, a holy nation, a redeemed people" (1 Pet. 2:9; cf. 2:4-5), is their right and duty by reason of their baptism.

In the restoration and promotion of the sacred liturgy, this full and active participation by all the people is the aim to be considered before all else; for it is the primary and indispensable source from which the faithful are to derive the true Christian spirit; and therefore pastors of souls must zealously strive to achieve it, by means of the necessary instruction, in all their pastoral work.

Yet it would be futile to entertain any hopes of realizing this unless the pastors themselves, in the first place, become thoroughly imbued with the spirit and power of the liturgy, and undertake to give instruction about it. A prime need, therefore, is that attention be directed, first of all, to thee liturgical instruction of the clergy. Wherefore the sacred Council has decided to enact as follows:

15.Professors who are appointed to teach liturgy in seminaries, religious houses of study, and theological faculties must be properly trained for their work in institutes which specialize in this subject.

16.The study of sacred liturgy is to be ranked among the compulsory and major courses in seminaries and religious houses of studies; in theological faculties it is to rank among the principal courses. It is to be taught under its theological, historical, spiritual, pastoral, and juridical aspects. Moreover, other professors, while striving to expound the mystery of Christ and the history of salvation from the angle proper to each of their own subjects, must nevertheless do so in a way which will clearly bring out the connection between their subjects and the liturgy, as also the unity which underlies all priestly training. This consideration is especially important for professors of dogmatic, spiritual, and pastoral theology and for those of holy scripture.

17.In seminaries and houses of religious, clerics shall be given a liturgical formation in their spiritual life. For this they will need proper direction, so that they may be able to understand the sacred rites and take part in them wholeheartedly; and they will also need personally to celebrate the sacred mysteries, as well as popular devotions which are imbued with the spirit of the liturgy. In addition they must learn how to observe the liturgical laws, so that life in seminaries and houses of religious may be thoroughly influenced by the spirit of the liturgy.

18.Priests, both secular and religious, who are already working in the Lord's vineyard are to be helped by every suitable means to understand ever more fully what it is that they are doing when they perform sacred rites; they are to be aided to live the liturgical life and to share it with the faithful entrusted to their care.

19.With zeal and patience, pastors of souls must promote the liturgical instruction of the faithful, and also their active participation in thee liturgy both internally and externally, taking into account their age and condition, their way of life, and standard of religious culture. By so doing, pastors will be fulfilling one of the chief duties of a faithful dispenser of the mysteries of God; and in this matter they must lead their flock not only in word but also by example.

20.Transmission of the sacred rites by radio and television shall be done with discretion and dignity, under the leadership and direction of a suitable person appointed for this office by the bishops. This is especially important when the service to be broadcast is the Mass.

Part 3. The Reform of the Sacred Liturgy

21.In order that the Christian people may more certainly derive an abundance of graces from the sacred liturgy, holy Mother Church desires to undertake with great care a general restoration of the liturgy itself. For the liturgy is made up of immutable elements divinely instituted, and of elements subject to change. These not only may but ought to be changed with the passage of time if they have suffered from the intrusion of anything out of harmony with the inner nature of the liturgy or have become unsuited to it.

In this restoration, both texts and rites should be drawn up so that they express more clearly the holy things which they signify; the Christian people, so far as possible, should be enabled to understand them with ease and to take part in them fully, actively, and as befits a community.

Wherefore the sacred Council establishes the following general norms:

A) General Norms

22.§1.Regulation of the sacred liturgy depends solely on the authority of the Church, that is, on the Apostolic See and, as laws may determine, on the bishop.

§2.In virtue of power conceded by the law, the regulation of the liturgy within certain defined limits belongs also to various kinds of competent territorial bodies of bishops legitimately established.

§3.Therefore no other person, even if he be a priest, may add, remove, or change anything in the liturgy on his own authority.

23.That sound tradition may bee retained, and yet the way remain open to legitimate progress, a careful investigation is always to be made into each part of the liturgy which is to be revised. This investigation should be theological, historical, and pastoral. Also the general laws governing the structure and meaning of the liturgy must be studied in conjunction with the experience derived from recent liturgical reforms and from the indults conceded to various places. Finally, there must be no innovations unless the good of the Church genuinely and certainly requires them; and care must be taken that any new forms adopted should in some way grow organically from forms already existing.

As far as possible, notable differences between the rites used in adjacent regions must be carefully avoided.

24.Sacred scripture is of the greatest importance in the celebration of the liturgy. For it is from scripture that lessons are read and explained in the homily, and psalms are sung; the prayers, collects, and liturgical songs are scriptural in their inspiration, and it is from the scriptures that actions and signs derive their meaning. Thus to achieve the restoration, progress, and adaptation of the sacred liturgy, it is essential to promote that warm and living love for scripture to which the venerable tradition of both eastern and western rites gives testimony.

25.The liturgical books are to be revised as soon as possible; experts are to be employed on the task, and bishops are to be consulted, from various parts of the world.

B) Norms Drawn from the Hierarchic and Communal Nature of the Liturgy

26.Liturgical services are not private functions, but are celebrations of the Church, which is the "sacrament of unity," namely, the holy people united and ordered under their bishops. [33]

Therefore liturgical services pertain to the whole body of the Church; they manifest it and have effects upon it; but they concern the individual members of the Church in different ways, according to their differing rank, office, and actual participation.

27.It is to be stressed that whenever rites, according to their specific nature, make provision for communal celebration involving the presence and active participation of the faithful, this way of celebrating them is to be preferred, so far as possible, to a celebration that is individual and quasi-private.

This applies with especial force to the celebration of Mass and the administration of the sacraments, even though every Mass has itself a public and social nature.

28.In liturgical celebrations each person, minister or layman, who has an office to perform, should do all of, but only, those parts which pertain to his office by the nature of the rite and the principles of liturgy.

29.Servers, lectors, commentators, and members of the choir also exercise a genuine liturgical function. They ought, therefore, to discharge their office with the sincere piety and decorum demanded by so exalted a ministry and rightly expected of them by God's people.

Consequently they must all be deeply imbued with the spirit of the liturgy, each in his own measure, and they must be trained to perform their functions in a correct and orderly manner.

30.To promote active participation, the people should be encouraged to take part by means of acclamations, responses, psalmody, antiphons, and songs, as well as by actions, gestures, and bodily attitudes. And at the proper times all should observe a reverent silence.

31.The revision of the liturgical books must carefully attend to the provision of rubrics also for the people's parts.

32.The liturgy makes distinctions between persons according to their liturgical function and sacred Orders, and there are liturgical laws providing for due honors to be given to civil authorities. Apart from these instances, no special honors are to be paid in the liturgy to any private persons or classes of persons, whether in the ceremonies or by external display.

C) Norms Based Upon the Didactic and Pastoral Nature of the Liturgy

33.Although the sacred liturgy is above all things the worship of the divine Majesty, it likewise contains much instruction for the faithful. [34] For in the liturgy God speaks to His people and Christ is still proclaiming His gospel. And the people reply to God both by song and prayer.

Moreover, the prayers addressed to God by the priest who presides over the assembly in the person of Christ are said in the name of the entire holy people and of all present. And the visible signs used by the liturgy to signify invisible divine things have been chosen by Christ or the Church. Thus not only when things are read "which were written for our instruction" (Rom. 15:4), but also when the Church prays or sings or acts, the faith of those taking part is nourished and their minds are raised to God, so that they may offer Him their rational service and more abundantly receive His grace.

Wherefore in the revision of the liturgy, the following general norms should be observed:

34.The rites should be distinguished by a noble simplicity; they should be short, clear, and unencumbered by useless repetitions; they should be within the people's powers of comprehension, and normally should not require much explanation.

35.That the intimate connection between words and rites may be apparent in the liturgy:

1. In sacred celebrations there is to be more reading from holy scripture, and it is to be more varied and suitable.
2. Because the sermon is part of the liturgical service, the best place for it is to be indicated even in the rubrics, as far as the nature of the rite will allow; the ministry of preaching is to be fulfilled with exactitude and fidelity. The sermon, moreover, should draw its content mainly from scriptural and liturgical sources, and its character should be that of a proclamation of God's wonderful works in the history of salvation, the mystery of Christ, ever made present and active within us, especially in the celebration of the liturgy.
3. Instruction which is more explicitly liturgical should also be given in a variety of ways; if necessary, short directives to be spoken by the priest or proper minister should be provided within the rites themselves. But they should occur only at the more suitable moments, and be in prescribed or similar words.
4. Bible services should be encouraged, especially on the vigils of the more solemn feasts, on some weekdays in Advent and Lent, and on Sundays and feast days. They are particularly to be commended in places where no priest is available; when this is so, a deacon or some other person authorized by the bishop should preside over the celebration.

36.§1.Particular law remaining in force, the use of the Latin language is to be preserved in the Latin rites.

§2.But since the use of the mother tongue, whether in the Mass, the administration of the sacraments, or other parts of the liturgy, frequently may be of great advantage to the people, the limits of its employment may be extended. This will apply in the first place to the readings and directives, and to some of the prayers and chants, according to the regulations on this matter to be laid down separately in subsequent chapters.

§3.These norms being observed, it is for the competent territorial ecclesiastical authority mentioned in Art. 22,§2, to decide whether, and to what extent, the vernacular language is to be used; their decrees are to be approved, that is, confirmed, by the Apostolic See. And, whenever it seems to be called for, this authority is to consult with bishops of neighboring regions which have the same language.

§4.Translations from the Latin text into the mother tongue intended for use in the liturgy must bee approved by the competent territorial ecclesiastical authority mentioned above.

D) Norms for Adapting the Liturgy to the Culture and Traditions of Peoples

37.Even in the liturgy, the Church has no wish to impose a rigid uniformity in matters which do not implicate the faith or the good of the whole community; rather does she respect and foster the genius and talents of the various races and peoples. Anything in these peoples' way of life which is not indisolubly bound up with superstition and error she studies with sympathy and , if possible, preserves intact. Sometimes in fact she admits such things into the liturgy itself, so long as they harmonize with its true and authentic spirit.

38.Provisions shall also bee made, when revising the liturgical books, for legitimate variations and adaptations to different groups, regions, and peoples, especially in mission lands, provided that the substantial unity of the Roman rite is preserved; and this should be borne in mind when drawing up the rites and devising rubrics.

39.Within the limits set by the typical editions of the liturgical books, it shall be for the competent territorial ecclesiastical authority mentioned in Art. 22, §2, to specify adaptations, especially in the case of the administration of the sacraments, the sacramentals, processions, liturgical language, sacred music, and the arts, but according to the fundamental norms laid down in this Constitution.

40.In some places and circumstances, however, an even more radical adaptation of the liturgy is needed, and this entails greater difficulties.

Wherefore:

1. The competent territorial ecclesiastical authority mentioned in Art. 22, §2, must, in this matter, carefully and prudently consider which elements from the traditions and culture of individual peoples might appropriately be admitted into divine worship. Adaptations which are judged to be useful or necessary should then be submitted to the Apostolic See, by whose consent they may be introduced.
2. To ensure that adaptations may be made with all the circumspection which they demand, the Apostolic See will grant power to this same territorial ecclesiastical authority to permit and to direct, as the case requires, the necessary preliminary experiments over a determined period of time among certain groups suited for the purpose.
3. Because liturgical laws often involve special difficulties with respect to adaptation, particularly in mission lands, men who are experts in these matters must be employed to formulate them.

Part 4. Promotion of Liturgical Life in Diocese and Parish

41.The bishop is to be considered as the high priest of his flock, from whom the life in Christ of his faithful is in some way derived and dependent.

Therefore all should hold in great esteem the liturgical life of the diocese centered around the bishop, especially in his cathedral church; they must be convinced that the pre-eminent manifestation of the Church consists in the full active participation of all God's holy people in these liturgical celebrations, especially in the same eucharist, in a single prayer, at one altar, at which there presides the bishop surrounded by his college of priests and by his ministers. [35]

42.But because it is impossible for the bishop always and everywhere to preside over the whole flock in his Church, he cannot do other than establish lesser groupings of the faithful. Among these the parishes, set up locally under a pastor who takes the place of the bishop, are the most important: for in some manner they represent the visible Church constituted throughout the world.

And therefore the liturgical life of the parish and its relationship to the bishop must be fostered theoretically and practically among the faithful and clergy; efforts also must be made to encourage a sense of community within the parish, above all in the common celebration of the Sunday Mass.

43.Zeal for the promotion and restoration of the liturgy is rightly held to be a sign of the providential disposition of God in our time, as a movement of the Holy Spirit in His Church. It is today a distinguishing mark of the Church's life, indeed of the whole tenor of contemporary religious thought and action.

So that this pastoral-liturgical action may become even more vigorous in the Church, the sacred Council decrees:

44.It is desirable that the competent territorial ecclesiastical authority mentioned in Art. 22, §2, set up a liturgical commission, to be assisted by experts in liturgical science, sacred music, art and pastoral practice. So far as possible the commission should be aided by some kind of Institute for Pastoral Liturgy, consisting of persons who are eminent in these matters, and including laymen as circumstances suggest. Under the direction of the above-mentioned territorial ecclesiastical authority the commission is to regulate pastoral-liturgical action throughout the territory, and to promote studies and necessary experiments whenever there is a question of adaptations to be proposed to the Apostolic See.

45.For the same reason every diocese is to have a commission on the sacred liturgy under the direction of the bishop, for promoting the liturgical apostolate.

Sometimes it may be expedient that several dioceses should form between them one single commission which will bee able to promote the liturgy by common consultation.

46.Besides the commission on the sacred liturgy, every diocese, as far as possible, should have commissions for sacred music and sacred art.

These three commissions must work in closest collaboration; indeed it will often be best to fuse the three of them into one single commission.
