Constitution on the Sacred Liturgy · promulgated by Pope Paul VI, 4 December 1963

  1. This sacred Council has several aims in view: it desires to impart an ever increasing vigor to the Christian life of the faithful; to adapt more suitably to the needs of our own times those institutions which are subject to change; to foster whatever can promote union among all who believe in Christ; to strengthen whatever can help to call the whole of mankind into the household of the Church. The Council therefore sees particularly cogent reasons for undertaking the reform and promotion of the liturgy.

  2. For the liturgy, “through which the work of our redemption is accomplished,” [1] most of all in the divine sacrifice of the Eucharist, is the outstanding means whereby the faithful may express in their lives, and manifest to others, the mystery of Christ and the real nature of the true Church. It is of the essence of the Church that she be both human and divine, visible and yet invisibly equipped, eager to act and yet intent on contemplation, present in this world and yet not at home in it; and she is all these things in such wise that in her the human is directed and subordinated to the divine, the visible likewise to the invisible, action to contemplation, and this present world to that city yet to come, which we seek [2]. While the liturgy daily builds up those who are within into a holy temple of the Lord, into a dwelling place for God in the Spirit [3], to the mature measure of the fullness of Christ [4], at the same time it marvelously strengthens their power to preach Christ, and thus shows forth the Church to those who are outside as a sign lifted up among the nations [5] under which the scattered children of God may be gathered together [6], until there is one sheepfold and one shepherd [7].

  3. Wherefore the sacred Council judges that the following principles concerning the promotion and reform of the liturgy should be called to mind, and that practical norms should be established.

Among these principles and norms there are some which can and should be applied both to the Roman rite and also to all the other rites. The practical norms which follow, however, should be taken as applying only to the Roman rite, except for those which, in the very nature of things, affect other rites as well.

  1. Lastly, in faithful obedience to tradition, the sacred Council declares that holy Mother Church holds all lawfully acknowledged rites to be of equal right and dignity; that she wishes to preserve them in the future and to foster them in every way. The Council also desires that, where necessary, the rites be revised carefully in the light of sound tradition, and that they be given new vigor to meet the circumstances and needs of modern times.

GENERAL PRINCIPLES FOR THE RESTORATION AND PROMOTION OF THE SACRED LITURGY

1. The Nature of the Sacred Liturgy and Its Importance in the Church’s Life

  1. 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 the 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].

  1. 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 the 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]; they receive the spirit of adoption as sons “in which we cry: 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 the 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 the 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.

  2. 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 the midst of them” (Matt. 18:20).
