Venerable Brethren, Health and Apostolic Benediction.
Mediator between God and men(1) and High Priest who has gone before us into heaven, Jesus the Son of
God(2) quite clearly had one aim in view when He undertook the mission of mercy which was to endow mankind with the rich blessings of supernatural grace. Sin had disturbed the right relationship between man and his
Creator; the Son of God would restore it. The children of Adam were wretched heirs to the infection of original sin; He would bring them back to their heavenly Father, the primal source and final destiny of all things.
For this reason He was not content, while He dwelt with us on earth, merely to give notice that redemption had begun, and to proclaim the long-awaited Kingdom of God, but gave Himself besides in prayer and sacrifice to
the task of saving souls, even to the point of offering Himself, as He hung from the cross, a Victim unspotted unto God, to purify our conscience of dead works, to serve the living God.(3) Thus happily were all men
summoned back from the byways leading them down to ruin and disaster, to be set squarely once again upon the path that leads to God. Thanks to the shedding of the blood of the Immaculate Lamb, now each might set about
the personal task of achieving his own sanctification, so rendering to God the glory due to Him.
2. But what is more, the divine Redeemer has
so willed it that the priestly life begun with the supplication and sacrifice of His mortal body should continue without intermission down the ages in His Mystical Body which is the Church. That is why He established a
visible priesthood to offer everywhere the clean oblation(4) which would enable men from East to West, freed from the shackles of sin, to offer God that unconstrained and voluntary homage which their conscience dictates.
3. In obedience, therefore, to her Founder's behest, the Church prolongs the priestly mission of Jesus Christ mainly by means of the sacred
liturgy. She does this in the first place at the altar, where constantly the sacrifice of the cross is represented(5) and with a single difference in the manner of its offering, renewed.(6) She does it next by means of
the sacraments, those special channels through which men are made partakers in the supernatural life. She does it, finally, by offering to God, all Good and Great, the daily tribute of her prayer of praise. "What a
spectacle for heaven and earth," observes Our predecessor of happy memory, Pius XI, "is not the Church at prayer! For centuries without interruption, from midnight to midnight, the divine psalmody of the
inspired canticles is repeated on earth; there is no hour of the day that is not hallowed by its special liturgy; there is no state of human life that has not its part in the thanksgiving, praise, supplication and
reparation of this common prayer of the Mystical Body of Christ which is His Church!"(7)
4. You are of course familiar with the fact,
Venerable Brethren, that a remarkably widespread revival of scholarly interest in the sacred liturgy took place towards the end of the last century and has continued through the early years of this one. The movement
owed its rise to commendable private initiative and more particularly to the zealous and persistent labor of several monasteries within the distinguished Order of Saint Benedict. Thus there developed in this field among
many European nations, and in lands beyond the seas as well, a rivalry as welcome as it was productive of results. Indeed, the salutary fruits of this rivalry among the scholars were plain for all to see, both in the
sphere of the sacred sciences, where the liturgical rites of the Western and Eastern Church were made the object of extensive research and profound study, and in the spiritual life of considerable numbers of individual
5. The majestic ceremonies of the sacrifice of the altar became better known, understood and appreciated. With more widespread
and more frequent reception of the sacraments, with the beauty of the liturgical prayers more fully savored, the worship of the Eucharist came to be regarded for what it really is: the fountain-head of genuine Christian
devotion. Bolder relief was given likewise to the fact that all the faithful make up a single and very compact body with Christ for its Head, and that the Christian community is in duty bound to participate in the
liturgical rites according to their station.
6. You are surely well aware that this Apostolic See has always made careful provision for the
schooling of the people committed to its charge in the correct spirit and practice of the liturgy; and that it has been no less careful to insist that the sacred rites should be performed with due external dignity. In
this connection We ourselves, in the course of our traditional address to the Lenten preachers of this gracious city of Rome in 1943, urged them warmly to exhort their respective hearers to more faithful participation
in the eucharistic sacrifice. Only a short while previously, with the design of rendering the prayers of the liturgy more correctly understood and their truth and unction more easy to perceive, We arranged to have the
Book of Psalms, which forms such an important part of these prayers in the Catholic Church, translated again into Latin from their original text.(8)
7. But while We derive no little satisfaction from the wholesome results of the movement just described, duty obliges Us to give serious attention to this "revival"
as it is advocated in some quarters, and to take proper steps to preserve it at the outset from excess or outright perversion.
though we are sorely grieved to note, on the one hand, that there are places where the spirit, understanding or practice of the sacred liturgy is defective, or all but inexistent, We observe with considerable anxiety
and some misgiving, that elsewhere certain enthusiasts, over-eager in their search for novelty, are straying beyond the path of sound doctrine and prudence. Not seldom, in fact, they interlard their plans and hopes for
a revival of the sacred liturgy with principles which compromise this holiest of causes in theory or practice, and sometimes even taint it with errors touching Catholic faith and ascetical doctrine.
9. Yet the integrity of faith and morals ought to be the special criterion of this sacred science, which must conform exactly to what the Church out of the
abundance of her wisdom teaches and prescribes. It is, consequently, Our prerogative to commend and approve whatever is done properly, and to check or censure any aberration from the path of truth and rectitude.
10. Let not the apathetic or half-hearted imagine, however, that We agree with them when We reprove the erring and restrain the overbold. No more must
the imprudent think that we are commending them when We correct the faults of those who are negligent and sluggish.
11. If in this encyclical
letter We treat chiefly of the Latin liturgy, it is not because We esteem less highly the venerable liturgies of the Eastern Church, whose ancient and honorable ritual traditions are just as dear to Us. The reason lies
rather in a special situation prevailing in the Western Church, of sufficient importance, it would seem, to require this exercise of Our authority.
12. With docile hearts, then, let all Christians hearken to the voice of their Common Father, who would have them, each and every one, intimately united with him as they
approach the altar of God, professing the same faith, obedient to the same law, sharing in the same Sacrifice with a single intention and one sole desire. This is a duty imposed, of course, by the honor due to God. But
the needs of our day and age demand it as well. After a long and cruel war which has rent whole peoples asunder with it rivalry and slaughter, men of good will are spending themselves in the effort to find the best
possible way to restore peace to the world. It is, notwithstanding, Our belief that no plan or initiative can offer better prospect of success than that fervent religious spirit and zeal by which Christians must be
formed and guided; in this way their common and whole-hearted acceptance of the same truth, along with their united obedience and loyalty to their appointed pastors, while rendering to God the worship due to Him, makes
of them one brotherhood: "for we, being many, are one body: all that partake of one bread."(9)
13. It is unquestionably the
fundamental duty of man to orientate his person and his life towards God. "For He it is to whom we must first be bound, as to an unfailing principle; to whom even our free choice must be directed as to an ultimate
objective. It is He, too, whom we lose when carelessly we sin. It is He whom we must recover by our faith and trust."(10) But man turns properly to God when he acknowledges His Supreme majesty and supreme
authority; when he accepts divinely revealed truths with a submissive mind; when he scrupulously obeys divine law, centering in God his every act and aspiration; when he accords, in short, due worship to the One True
God by practicing the virtue of religion .
14. This duty is incumbent, first of all, on men as individuals. But it also binds the whole
community of human beings, grouped together by mutual social ties: mankind, too, depends on the sovereign authority of God.
15. It should be
noted, moreover, that men are bound by his obligation in a special way in virtue of the fact that God has raised them to the supernatural order.
16. Thus we observe that when God institutes the Old Law, He makes provision besides for sacred rites, and determines in exact detail the rules to be observed by His people
in rendering Him the worship He ordains. To this end He established various kinds of sacrifice and designated the ceremonies with which they were to be offered to Him. His enactments on all matters relating to the Ark
of the Covenant, the Temple and the holy days are minute and clear. He established a sacerdotal tribe with its high priest, selected and described the vestments with which the sacred ministers were to be clothed, and
every function in any way pertaining to divine worship.(11) Yet this was nothing more than a faint foreshadowing(12) of the worship which the High Priest of the New Testament was to render to the Father in heaven.
17. No sooner, in fact, "is the Word made flesh"(13) than he shows Himself to the world vested with a priestly office, making to the
Eternal Father an act of submission which will continue uninterruptedly as long as He lives: "When He cometh into the world he saith. . . 'behold I come . . . to do Thy Will."(14) This act He was to consummate
admirably in the bloody Sacrifice of the Cross: "It is in this will we are sanctified by the oblation of the Body of Jesus Christ once."(15) He plans His active life among men with no other purpose in view. As
a child He is presented to the Lord in the Temple. To the Temple He returns as a grown boy, and often afterwards to instruct the people and to pray. He fasts for forty days before beginning His public ministry. His
counsel and example summon all to prayer, daily and at night as well. As Teacher of the truth He "enlighteneth every man"(16) to the end that mortals may duly acknowledge the immortal God, "not
withdrawing unto perdition, but faithful to the saving of the soul."(17) As Shepherd He watches over His flock, leads it to life-giving pasture, lays down a law that none shall wander from His side, off the
straight path He has pointed out, and that all shall lead holy lives imbued with His spirit and moved by His active aid. At the Last Supper He celebrates a new Pasch with solemn rite and ceremonial, and provides for its
continuance through the divine institution of the Eucharist. On the morrow, lifted up between heaven and earth, He offers the saving sacrifice of His life, and pours forth, as it were, from His pierced Heart the
sacraments destined to impart the treasures of redemption to the souls of men. All this He does with but a single aim: the glory of His Father and man's ever greater sanctification.
18. But it is His will, besides, that the worship He instituted and practiced during His life on earth shall continue ever afterwards without intermission. For he has not
left mankind an orphan. He still offers us the support of His powerful, unfailing intercession, acting as our "advocate with the Father."(18) He aids us likewise through His Church, where He is present
indefectibly as the ages run their course: through the Church which He constituted "the pillar of truth"(19) and dispenser of grace, and which by His sacrifice on the cross, He founded, consecrated and
19. The Church has, therefore, in common with the Word Incarnate the aim, the obligation and the function of teaching
all men the truth, of governing and directing them aright, of offering to God the pleasing and acceptable sacrifice; in this way the Church re-establishes between the Creator and His creatures that unity and harmony to
which the Apostle of the Gentiles alludes in these words: "Now, therefore, you are no more strangers and foreigners; but you are fellow citizens with the saints and domestics of God, built upon the foundation of
the apostles and prophets, Jesus Christ Himself being the chief corner-stone; in whom all the building, being framed together, groweth up into a holy temple in the Lord, in whom you also are built together in a
habitation of God in the Spirit."(21) Thus the society founded by the divine Redeemer, whether in her doctrine and government, or in the sacrifice and sacraments instituted by Him, or finally, in the ministry,
which He has confided to her charge with the outpouring of His prayer and the shedding of His blood, has no other goal or purpose than to increase ever in strength and unity.
20. This result is, in fact, achieved when Christ lives and thrives, as it were, in the hearts of men, and when men's hearts in turn are fashioned and expanded as though by
Christ. This makes it possible for the sacred temple, where the Divine Majesty receives the acceptable worship which His law prescribes, to increase and prosper day by day in this land of exile of earth. Along with the
Church, therefore, her Divine Founder is present at every liturgical function: Christ is present at the august sacrifice of the altar both in the person of His minister and above all under the eucharistic species. He is
present in the sacraments, infusing into them the power which makes them ready instruments of sanctification. He is present, finally, in prayer of praise and petition we direct to God, as it is written: "Where
there are two or three gathered together in My Name, there am I in the midst of them."(22) The sacred liturgy is, consequently, the public worship which our Redeemer as Head of the Church renders to the Father, as
well as the worship which the community of the faithful renders to its Founder, and through Him to the heavenly Father. It is, in short, the worship rendered by the Mystical Body of Christ in the entirety of its Head
21. Liturgical practice begins with the very founding of the Church. The first Christians, in fact, "were persevering in
the doctrine of the apostles and in the communication of the breaking of bread and in prayers."(23) Whenever their pastors can summon a little group of the faithful together, they set up an altar on which they
proceed to offer the sacrifice, and around which are ranged all the other rites appropriate for the saving of souls and for the honor due to God. Among these latter rites, the first place is reserved for the sacraments,
namely, the seven principal founts of salvation. There follows the celebration of the divine praises in which the faithful also join, obeying the behest of the Apostle Paul, "In all wisdom, teaching and admonishing
one another in psalms, hymns and spiritual canticles, singing in grace in your hearts to God."(24) Next comes the reading of the Law, the prophets, the gospel and the apostolic epistles; and last of all the homily
or sermon in which the official head of the congregation recalls and explains the practical bearing of the commandments of the divine Master and the chief events of His life, combining instruction with appropriate
exhortation and illustration of the benefit of all his listeners.
22. As circumstances and the needs of Christians warrant, public worship is
organized, developed and enriched by new rites, ceremonies and regulations, always with the single end in view, "that we may use these external signs to keep us alert, learn from them what distance we have come
along the road, and by them be heartened to go on further with more eager step; for the effect will be more precious the warmer the affection which precedes it."(25) Here then is a better and more suitable way to
raise the heart to God. Thenceforth the priesthood of Jesus Christ is a living and continuous reality through all the ages to the end of time, since the liturgy is nothing more nor less than the exercise of this
priestly function. Like her divine Head, the Church is forever present in the midst of her children. She aids and exhorts them to holiness, so that they may one day return to the Father in heaven clothed in that
beauteous raiment of the supernatural. To all who are born to life on earth she gives a second, supernatural kind of birth. She arms them with the Holy Spirit for the struggle against the implacable enemy. She gathers
all Christians about her altars, inviting and urging them repeatedly to take part in the celebration of the Mass, feeding them with the Bread of angels to make them ever stronger. She purifies and consoles the hearts
that sin has wounded and soiled. Solemnly she consecrates those whom God has called to the priestly ministry. She fortifies with new gifts of grace the chaste nuptials of those who are destined to found and bring up a
Christian family. When as last she has soothed and refreshed the closing hours of this earthly life by holy Viaticum and extreme unction, with the utmost affection she accompanies the mortal remains of her children to
the grave, lays them reverently to rest, and confides them to the protection of the cross, against the day when they will triumph over death and rise again. She has a further solemn blessing and invocation for those of
her children who dedicate themselves to the service of God in the life of religious perfection. Finally, she extends to the souls in purgatory, who implore her intercession and her prayers, the helping hand which may
lead them happily at last to eternal blessedness in heaven.
23. The worship rendered by the Church to God must be, in its entirety, interior
as well as exterior. It is exterior because the nature of man as a composite of body and soul requires it to be so. Likewise, because divine Providence has disposed that "while we recognize God visibly, we may be
drawn by Him to love of things unseen."(26) Every impulse of the human heart, besides, expresses itself naturally through the senses; and the worship of God, being the concern not merely of individuals but of the
whole community of mankind, must therefore be social as well. This obviously it cannot be unless religious activity is also organized and manifested outwardly. Exterior worship, finally, reveals and emphasizes the unity
of the mystical Body, feeds new fuel to its holy zeal, fortifies its energy, intensifies its action day by day: "for although the ceremonies themselves can claim no perfection or sanctity in their won right, they
are, nevertheless, the outward acts of religion, designed to rouse the heart, like signals of a sort, to veneration of the sacred realities, and to raise the mind to meditation on the supernatural. They serve to foster
piety, to kindle the flame of charity, to increase our faith and deepen our devotion. They provide instruction for simple folk, decoration for divine worship, continuity of religious practice. They make it possible to
tell genuine Christians from their false or heretical counterparts."(27)
24. But the chief element of divine worship must be interior.
For we must always live in Christ and give ourselves to Him completely, so that in Him, with Him and through Him the heavenly Father may be duly glorified. The sacred liturgy requires, however, that both of these
elements be intimately linked with each another. This recommendation the liturgy itself is careful to repeat, as often as it prescribes an exterior act of worship. Thus we are urged, when there is question of fasting,
for example, "to give interior effect to our outward observance."(28) Otherwise religion clearly amounts to mere formalism, without meaning and without content. You recall, Venerable Brethren, how the divine
Master expels from the sacred temple, as unworthily to worship there, people who pretend to honor God with nothing but neat and wellturned phrases, like actors in a theater, and think themselves perfectly capable of
working out their eternal salvation without plucking their inveterate vices from their hearts.(29) It is, therefore, the keen desire of the Church that all of the faithful kneel at the feet of the Redeemer to tell Him
how much they venerate and love Him. She wants them present in crowds--like the children whose joyous cries accompanied His entry into Jerusalem--to sing their hymns and chant their song of praise and thanksgiving to
Him who is King of Kings and Source of every blessing. She would have them move their lips in prayer, sometimes in petition, sometimes in joy and gratitude, and in this way experience His merciful aid and power like the
apostles at the lakeside of Tiberias, or abandon themselves totally, like Peter on Mount Tabor, to mystic union with the eternal God in contemplation.
25. It is an error, consequently, and a mistake to think of the sacred liturgy as merely the outward or visible part of divine worship or as an ornamental ceremonial. No less
erroneous is the notion that it consists solely in a list of laws and prescriptions according to which the ecclesiastical hierarchy orders the sacred rites to be performed.
26. It should be clear to all, then, that God cannot be honored worthily unless the mind and heart turn to Him in quest of the perfect life, and that the worship rendered to
God by the Church in union with her divine Head is the most efficacious means of achieving sanctity.
27. This efficacy, where there is
question of the eucharistic sacrifice and the sacraments, derives first of all and principally from the act itself (ex opere operato). But if one considers the part which the Immaculate Spouse of Jesus Christ takes in
the action, embellishing the sacrifice and sacraments with prayer and sacred ceremonies, or if one refers to the "sacramentals" and the other rites instituted by the hierarchy of the Church, then its
effectiveness is due rather to the action of the church (ex opere operantis Ecclesiae), inasmuch as she is holy and acts always in closest union with her Head.
28. In this connection, Venerable Brethren, We desire to direct your attention to certain recent theories touching a so-called "objective" piety. While these
theories attempt, it is true, to throw light on the mystery of the Mystical Body, on the effective reality of sanctifying grace, on the action of God in the sacraments and in the Mass, it is nonetheless apparent that
they tend to belittle, or pass over in silence, what they call "subjective," or "personal" piety.
29. It is an
unquestionable fact that the work of our redemption is continued, and that its fruits are imparted to us, during the celebration of the liturgy, notable in the august sacrifice of the altar. Christ acts each day to save
us, in the sacraments and in His holy sacrifice. By means of them He is constantly atoning for the sins of mankind, constantly consecrating it to God. Sacraments and sacrifice do, then, possess that
"objective" power to make us really and personally sharers in the divine life of Jesus Christ. Not from any ability of our own, but by the power of God, are they endowed with the capacity to unite the piety of
members with that of the head, and to make this, in a sense, the action of the whole community. From these profound considerations some are led to conclude that all Christian piety must be centered in the mystery of the
Mystical Body of Christ, with no regard for what is "personal" or "subjective, as they would have it. As a result they feel that all other religious exercises not directly connected with the sacred
liturgy, and performed outside public worship should be omitted.
30. But though the principles set forth above are excellent, it must be
plain to everyone that the conclusions drawn from them respecting two sorts of piety are false, insidious and quite pernicious.
truly, the sacraments and the sacrifice of the altar, being Christ's own actions, must be held to be capable in themselves of conveying and dispensing grace from the divine Head to the members of the Mystical Body. But
if they are to produce their proper effect, it is absolutely necessary that our hearts be properly disposed to receive them. Hence the warning of Paul the Apostle with reference to holy communion, "But let a man
first prove himself; and then let him eat of this bread and drink of the chalice."(30) This explains why the Church in a brief and significant phrase calls the various acts of mortification, especially those
practiced during the season of Lent, "the Christian army's defenses."(31) They represent, in fact, the personal effort and activity of members who desire, as grace urges and aids them, to join forces with
their Captain--"that we may discover . . . in our Captain," to borrow St. Augustine's words, "the fountain of grace itself."(32) But observe that these members are alive, endowed and equipped with an
intelligence and will of their own. It follows that they are strictly required to put their own lips to the fountain, imbibe and absorb for themselves the life-giving water, and rid themselves personally of anything
that might hinder its nutritive effect in their souls. Emphatically, therefore, the work of redemption, which in itself is independent of our will, requires a serious interior effort on our part if we are to achieve
32. If the private and interior devotion of individuals were to neglect the august sacrifice of the altar and the
sacraments, and to withdraw them from the stream of vital energy that flows from Head to members, it would indeed be sterile, and deserve to be condemned. But when devotional exercises, and pious practices in general,
not strictly connected with the sacred liturgy, confine themselves to merely human acts, with the express purpose of directing these latter to the Father in heaven, of rousing people to repentance and holy fear of God,
of weaning them from the seductions of the world and its vice, and leading them back to the difficult path of perfection, then certainly such practices are not only highly praiseworthy but absolutely indispensable,
because they expose the dangers threatening the spiritual life; because they promote the acquisition of virtue; and because they increase the fervor and generosity with which we are bound to dedicate all that we are and
all that we have to the service of Jesus Christ. Genuine and real piety, which the Angelic Doctor calls "devotion," and which is the principal act of the virtue of religion--that act which correctly relates
and fitly directs men to God; and by which they freely and spontaneously give themselves to the worship of God in its fullest sense(33)--piety of this authentic sort needs meditation on the supernatural realities and
spiritual exercises, if it is to be nurtured, stimulated and sustained, and if it is to prompt us to lead a more perfect life. For the Christian religion, practiced as it should be, demands that the will especially be
consecrated to God and exert its influence on all the other spiritual faculties. But every act of the will presupposes an act of the intelligence, and before one can express the desire and the intention of offering
oneself in sacrifice to the eternal Godhead, a knowledge of the facts and truths which make religion a duty is altogether necessary. One must first know, for instance, man's last end and the supremacy of the Divine
Majesty; after that, our common duty of submission to our Creator; and, finally, the inexhaustible treasures of love with which God yearns to enrich us, as well as the necessity of supernatural grace for the achievement
of our destiny, and that special path marked out for us by divine Providence in virtue of the fact that we have been united, one and all, like members of a body, to Jesus Christ the Head. But further, since our hearts,
disturbed as they are at times by the lower appetites, do not always respond to motives of love, it is also extremely helpful to let consideration and contemplation of the justice of God provoke us on occasion to
salutary fear, and guide us thence to Christian humility, repentance and amendment.
33. But it will not do to possess these facts and truths
after the fashion of an abstract memory lesson or lifeless commentary. They must lead to practical results. They must impel us to subject our senses and their faculties to reason, as illuminated by the Catholic faith.
They must help to cleanse and purify the heart, uniting it to Christ more intimately every day, growing ever more to His likeness, and drawing from Him the divine inspiration and strength of which it stands in need.
They must serve as increasingly effective incentives to action: urging men to produce good fruit, to perform their individual duties faithfully, to give themselves eagerly to the regular practice of their religion and
the energetic exercise of virtue. "You are Christ's, and Christ is God's."(34) Let everything, therefore, have its proper place and arrangement; let everything be "theocentric," so to speak, if we
really wish to direct everything to the glory of God through the life and power which flow from the divine Head into our hearts: "Having therefore, brethren, a confidence in the entering into the holies by the
blood of Christ, a new and living way which He both dedicated for us through the veil, that is to say, His flesh, and a high priest over the house of God; let us draw near with a true heart, in fullness of faith, having
our hearts sprinkled from an evil conscience and our bodies washed with clean water, let us hold fast the confession of our hope without wavering . . . and let us consider one another, to provoke unto charity and to
34. Here is the source of the harmony and equilibrium which prevails among the members of the Mystical Body of Jesus
Christ. When the Church teaches us our Catholic faith and exhorts us to obey the commandments of Christ, she is paving a way for her priestly, sanctifying action in its highest sense; she disposes us likewise for more
serious meditation on the life of the divine Redeemer and guides us to profounder knowledge of the mysteries of faith where we may draw the supernatural sustenance, strength and vitality that enable us to progress
safely, through Christ, towards a more perfect life. Not only through her ministers but with the help of the faithful individually, who have imbibed in this fashion the spirit of Christ, the Church endeavors to permeate
with this same spirit the life and labors of men--their private and family life, their social, even economic and political life--that all who are called God's children may reach more readily the end He has proposed for
35. Such action on the part of individual Christians, then, along with the ascetic effort promoting them to purify their hearts,
actually stimulates in the faithful those energies which enable them to participate in the august sacrifice of the altar with better dispositions. They now can receive the sacraments with more abundant fruit, and come
from the celebration of the sacred rites more eager, more firmly resolved to pray and deny themselves like Christians, to answer the inspirations and invitation of divine grace and to imitate daily more closely the
virtues of our Redeemer. And all of this not simply for their own advantage, but for that of the whole Church, where whatever good is accomplished proceeds from the power of her Head and redounds to the advancement of
all her members.
36. In the spiritual life, consequently, there can be no opposition between the action of God, who pours forth His grace
into men's hearts so that the work of the redemption may always abide, and the tireless collaboration of man, who must not render vain the gift of God.(36) No more can the efficacy of the external administration of the
sacraments, which comes from the rite itself (ex opere operato), be opposed to the meritorious action of their ministers of recipients, which we call the agent's action (opus operantis). Similarly, no conflict exists
between public prayer and prayers in private, between morality and contemplation, between the ascetical life and devotion to the liturgy. Finally, there is no opposition between the jurisdiction and teaching office of
the ecclesiastical hierarchy, and the specifically priestly power exercised in the sacred ministry.
37. Considering their special designation
to perform the liturgical functions of the holy sacrifice and divine office, the Church has serious reason for prescribing that the ministers she assigns to the service of the sanctuary and members of religious
institutes betake themselves at stated times to mental prayer, to examination of conscience, and to various other spiritual exercises.(37) Unquestionably, liturgical prayer, being the public supplication of the
illustrious Spouse of Jesus Christ, is superior in excellence to private prayers. But this superior worth does not at all imply contrast or incompatibility between these two kinds of prayer. For both merge harmoniously
in the single spirit which animates them, "Christ is all and in all."(38) Both tend to the same objective: until Christ be formed in us.(39)
38. For a better and more accurate understanding of the sacred liturgy another of its characteristic features, no less important, needs to be considered.
39. The Church is a society, and as such requires an authority and hierarchy of her own. Though it is true that all the members of the Mystical Body partake of
the same blessings and pursue the same objective, they do not all enjoy the same powers, nor are they all qualified to perform the same acts. The divine Redeemer has willed, as a matter of fact, that His Kingdom should
be built and solidly supported, as it were, on a holy order, which resembles in some sort the heavenly hierarchy.
40. Only to the apostles,
and thenceforth to those on whom their successors have imposed hands, is granted the power of the priesthood, in virtue of which they represent the person of Jesus Christ before their people, acting at the same time as
representatives of their people before God. This priesthood is not transmitted by heredity or human descent. It does not emanate from the Christian community. It is not a delegation from the people. Prior to acting as
representative of the community before the throne of God, the priest is the ambassador of the divine Redeemer. He is God's vice-regent in the midst of his flock precisely because Jesus Christ is Head of that body of
which Christians are the members. The power entrusted to him, therefore, bears no natural resemblance to anything human. It is entirely supernatural. It comes from God. "As the Father hath sent me, I also send
you(40). . . he that heareth you heareth me(41). . . go ye into the whole world and preach the gospel to every creature; he that believeth and is baptized shall be saved."(42)
41. That is why the visible, external priesthood of Jesus Christ is not handed down indiscriminately to all members of the Church in general, but is conferred on designated
men, through what may be called the spiritual generation of holy orders.
42. This latter, one of the seven sacraments, not only imparts the
grace appropriate to the clerical function and state of life, but imparts an indelible "character" besides, indicating the sacred ministers' conformity to Jesus Christ the Priest and qualifying them to perform
those official acts of religion by which men are sanctified and God is duly glorified in keeping with the divine laws and regulations.
the same way, actually that baptism is the distinctive mark of all Christians, and serves to differentiate them from those who have not been cleansed in this purifying stream and consequently are not members of Christ,
the sacrament of holy orders sets the priest apart from the rest of the faithful who have not received this consecration. For they alone, in answer to an inward supernatural call, have entered the august ministry, where
they are assigned to service in the sanctuary and become, as it were, the instruments God uses to communicate supernatural life from on high to the Mystical Body of Jesus Christ. Add to this, as We have noted above, the
fact that they alone have been marked with the indelible sign "conforming" them to Christ the Priest, and that their hands alone have been consecrated "in order that whatever they bless may be blessed,
whatever they consecrate may become sacred and holy, in the name of our Lord Jesus Christ"(43) Let all, then, who would live in Christ flock to their priests. By them they will be supplied with the comforts and
food of the spiritual life. From them they will procure the medicine of salvation assuring their cure and happy recovery from the fatal sickness of their sins. The priest, finally, will bless their homes, consecrate
their families and help them, as they breathe their last, across the threshold of eternal happiness.
44. Since, therefore, it is the priest
chiefly who performs the sacred liturgy in the name of the Church, its organization, regulation and details cannot but be subject to Church authority. This conclusion, based on the nature of Christian worship itself, is
further confirmed by the testimony of history.
45. Additional proof of this indefeasible right of the ecclesiastical hierarchy lies in the
circumstances that the sacred liturgy is intimately bound up with doctrinal propositions which the Church proposes to be perfectly true and certain, and must as a consequence conform to the decrees respecting Catholic
faith issued by the supreme teaching authority of the Church with a view to safeguarding the integrity of the religion revealed by God.
On this subject We judge it Our duty to rectify an attitude with which you are doubtless familiar, Venerable Brethren. We refer to the error and fallacious reasoning of those who have claimed that the sacred liturgy is
a kind of proving ground for the truths to be held of faith, meaning by this that the Church is obliged to declare such a doctrine sound when it is found to have produced fruits of piety and sanctity through the sacred
rites of the liturgy, and to reject it otherwise. Hence the epigram, "Lex orandi, lex credendi"--the law for prayer is the law for faith.
47. But this is not what the Church teaches and enjoins. The worship she offers to God, all good and great, is a continuous profession of Catholic faith and a continuous
exercise of hope and charity, as Augustine puts it tersely. "God is to be worshipped," he says, "by faith, hope and charity."(44) In the sacred liturgy we profess the Catholic faith explicitly and
openly, not only by the celebration of the mysteries, and by offering the holy sacrifice and administering the sacraments, but also by saying or singing the credo or Symbol of the faith--it is indeed the sign and badge,
as it were, of the Christian--along with other texts, and likewise by the reading of holy scripture, written under the inspiration of the Holy Ghost. The entire liturgy, therefore, has the Catholic faith for its
content, inasmuch as it bears public witness to the faith of the Church.
48. For this reason, whenever there was question of defining a truth
revealed by God, the Sovereign Pontiff and the Councils in their recourse to the "theological sources," as they are called, have not seldom drawn many an argument from this sacred science of the liturgy. For
an example in point, Our predecessor of immortal memory, Pius IX, so argued when he proclaimed the Immaculate Conception of the Virgin Mary. Similarly during the discussion of a doubtful or controversial truth, the
Church and the Holy Fathers have not failed to look to the age-old and age-honored sacred rites for enlightenment. Hence the well-known and venerable maxim, "Legem credendi lex statuat supplicandi"--let the
rule for prayer determine the rule of belief.(45) The sacred liturgy, consequently, does not decide or determine independently and of itself what is of Catholic faith. More properly, since the liturgy is also a
profession of eternal truths, and subject, as such, to the supreme teaching authority of the Church, it can supply proofs and testimony, quite clearly, of no little value, towards the determination of a particular point
of Christian doctrine. But if one desires to differentiate and describe the relationship between faith and the sacred liturgy in absolute and general terms, it is perfectly correct to say, "Lex credendi legem
statuat supplicandi"--let the rule of belief determine the rule of prayer. The same holds true for the other theological virtues also, "In . . . fide, spes, caritate continuato desiderio semper
oramus"--we pray always, with constant yearning in faith, hope and charity.(46)
49. From time immemorial the ecclesiastical hierarchy
has exercised this right in matters liturgical. It has organized and regulated divine worship, enriching it constantly with new splendor and beauty, to the glory of God and the spiritual profit of Christians. What is
more, it has not been slow--keeping the substance of the Mass and sacraments carefully intact--to modify what it deemed not altogether fitting, and to add what appeared more likely to increase the honor paid to Jesus
Christ and the august Trinity, and to instruct and stimulate the Christian people to greater advantage.(47)
50. The sacred liturgy does, in
fact, include divine as well as human elements. The former, instituted as they have been by God, cannot be changed in any way by men. But the human components admit of various modifications, as the needs of the age,
circumstance and the good of souls may require, and as the ecclesiastical hierarchy, under guidance of the Holy Spirit, may have authorized. This will explain the marvelous variety of Eastern and Western rites. Here is
the reason for the gradual addition, through successive development, of particular religious customs and practices of piety only faintly discernible in earlier times. Hence likewise it happens from time to time that
certain devotions long since forgotten are revived and practiced anew. All these developments attest the abiding life of the immaculate Spouse of Jesus Christ through these many centuries. They are the sacred language
she uses, as the ages run their course, to profess to her divine Spouse her own faith along with that of the nations committed to her charge, and her own unfailing love. They furnish proof, besides, of the wisdom of the
teaching method she employs to arouse and nourish constantly the "Christian instinct."
51. Several causes, really have been
instrumental in the progress and development of the sacred liturgy during the long and glorious life of the Church.
52. Thus, for example, as
Catholic doctrine on the Incarnate Word of God, the eucharistic sacrament and sacrifice, and Mary the Virgin Mother of God came to be determined with greater certitude and clarity, new ritual forms were introduced
through which the acts of the liturgy proceeded to reproduce this brighter light issuing from the decrees of the teaching authority of the Church, and to reflect it, in a sense so that it might reach the minds and
hearts of Christ's people more readily.
53. The subsequent advances in ecclesiastical discipline for the administering of the sacraments,
that of penance for example; the institution and later suppression of the catechumenate; and again, the practice of eucharistic communion under a single species, adopted in the Latin Church; these developments were
assuredly responsible in no little measure for the modification of the ancient ritual in the course of time, and for the gradual introduction of new rites considered more in accord with prevailing discipline in these
54. Just as notable a contribution to this progressive transformation was made by devotional trends and practices not directly
related to the sacred liturgy, which began to appear, by God's wonderful design, in later periods, and grew to be so popular. We may instance the spread and ever mounting ardor of devotion to the Blessed Eucharist,
devotion to the most bitter passion of our Redeemer, devotion to the most Sacred Heart of Jesus, to the Virgin Mother of God and to her most chaste spouse.
55. Other manifestations of piety have also played their circumstantial part in this same liturgical development. Among them may be cited the public pilgrimages to the tombs
of the martyrs prompted by motives of devotion, the special periods of fasting instituted for the same reason, and lastly, in this gracious city of Rome, the penitential recitation of the litanies during the
"station" processions, in which even the Sovereign Pontiff frequently joined.
56. It is likewise easy to understand that the
progress of the fine arts, those of architecture, painting and music above all, has exerted considerable influence on the choice and disposition of the various external features of the sacred liturgy.
57. The Church has further used her right of control over liturgical observance to protect the purity of divine worship against abuse from dangerous and
imprudent innovations introduced by private individuals and particular churches. Thus it came about--during the 16th century, when usages and customs of this sort had become increasingly prevalent and exaggerated, and
when private initiative in matters liturgical threatened to compromise the integrity of faith and devotion, to the great advantage of heretics and further spread of their errors--that in the year 1588, Our predecessor
Sixtus V of immortal memory established the Sacred Congregation of Rites, charged with the defense of the legitimate rites of the Church and with the prohibition of any spurious innovation.(48) This body fulfills even
today the official function of supervision and legislation with regard to all matters touching the sacred liturgy.(49)
58. It follows from
this that the Sovereign Pontiff alone enjoys the right to recognize and establish any practice touching the worship of God, to introduce and approve new rites, as also to modify those he judges to require
modification.(50) Bishops, for their part, have the right and duty carefully to watch over the exact observance of the prescriptions of the sacred canons respecting divine worship.(51) Private individuals, therefore,
even though they be clerics, may not be left to decide for themselves in these holy and venerable matters, involving as they do the religious life of Christian society along with the exercise of the priesthood of Jesus
Christ and worship of God; concerned as they are with the honor due to the Blessed Trinity, the Word Incarnate and His august mother and the other saints, and with the salvation of souls as well. For the same reason no
private person has any authority to regulate external practices of this kind, which are intimately bound up with Church discipline and with the order, unity and concord of the Mystical Body and frequently even with the
integrity of Catholic faith itself.
59. The Church is without question a living organism, and as an organism, in respect of the sacred
liturgy also, she grows, matures, develops, adapts and accommodates herself to temporal needs and circumstances, provided only that the integrity of her doctrine be safeguarded. This notwithstanding, the temerity and
daring of those who introduce novel liturgical practices, or call for the revival of obsolete rites out of harmony with prevailing laws and rubrics, deserve severe reproof. It has pained Us grievously to note, Venerable
Brethren, that such innovations are actually being introduced, not merely in minor details but in matters of major importance as well. We instance, in point of fact, those who make use of the vernacular in the
celebration of the august eucharistic sacrifice; those who transfer certain feast-days--which have been appointed and established after mature deliberation--to other dates; those, finally, who delete from the
prayerbooks approved for public use the sacred texts of the Old Testament, deeming them little suited and inopportune for modern times.
The use of the Latin language, customary in a considerable portion of the Church, is a manifest and beautiful sign of unity, as well as an effective antidote for any corruption of doctrinal truth. In spite of this, the
use of the mother tongue in connection with several of the rites may be of much advantage to the people. But the Apostolic See alone is empowered to grant this permission. It is forbidden, therefore, to take any action
whatever of this nature without having requested and obtained such consent, since the sacred liturgy, as We have said, is entirely subject to the discretion and approval of the Holy See.
61. The same reasoning holds in the case of some persons who are bent on the restoration of all the ancient rites and ceremonies indiscriminately. The liturgy of the early
ages is most certainly worthy of all veneration. But ancient usage must not be esteemed more suitable and proper, either in its own right or in its significance for later times and new situations, on the simple ground
that it carries the savor and aroma of antiquity. The more recent liturgical rites likewise deserve reverence and respect. They, too, owe their inspiration to the Holy Spirit, who assists the Church in every age even to
the consummation of the world.(52) They are equally the resources used by the majestic Spouse of Jesus Christ to promote and procure the sanctity of man.
62. Assuredly it is a wise and most laudable thing to return in spirit and affection to the sources of the sacred liturgy. For research in this field of study, by tracing it
back to its origins, contributes valuable assistance towards a more thorough and careful investigation of the significance of feast-days, and of the meaning of the texts and sacred ceremonies employed on their occasion.
But it is neither wise nor laudable to reduce everything to antiquity by every possible device. Thus, to cite some instances, one would be straying from the straight path were he to wish the altar restored to its
primitive tableform; were he to want black excluded as a color for the liturgical vestments; were he to forbid the use of sacred images and statues in Churches; were he to order the crucifix so designed that the divine
Redeemer's body shows no trace of His cruel sufferings; and lastly were he to disdain and reject polyphonic music or singing in parts, even where it conforms to regulations issued by the Holy See.
63. Clearly no sincere Catholic can refuse to accept the formulation of Christian doctrine more recently elaborated and proclaimed as dogmas by the Church, under
the inspiration and guidance of the Holy Spirit with abundant fruit for souls, because it pleases him to hark back to the old formulas. No more can any Catholic in his right senses repudiate existing legislation of the
Church to revert to prescriptions based on the earliest sources of canon law. Just as obviously unwise and mistaken is the zeal of one who in matters liturgical would go back to the rites and usage of antiquity,
discarding the new patterns introduced by disposition of divine Providence to meet the changes of circumstances and situation.
64. This way
of acting bids fair to revive the exaggerated and senseless antiquarianism to which the illegal Council of Pistoia gave rise. It likewise attempts to reinstate a series of errors which were responsible for the calling
of that meeting as well as for those resulting from it, with grievous harm to souls, and which the Church, the ever watchful guardian of the "deposit of faith" committed to her charge by her divine Founder,
had every right and reason to condemn.(53) For perverse designs and ventures of this sort tend to paralyze and weaken that process of sanctification by which the sacred liturgy directs the sons of adoption to their
Heavenly Father of their souls' salvation.
65. In every measure taken, then, let proper contact with the ecclesiastical hierarchy be
maintained. Let no one arrogate to himself the right to make regulations and impose them on others at will. Only the Sovereign Pontiff, as the successor of Saint Peter, charged by the divine Redeemer with the feeding of
His entire flock,(54) and with him, in obedience to the Apostolic See, the bishops "whom the Holy Ghost has placed . . . to rule the Church of God,"(55) have the right and the duty to govern the Christian
people. Consequently, Venerable Brethren, whenever you assert your authority--even on occasion with wholesome severity--you are not merely acquitting yourselves of your duty; you are defending the very will of the
Founder of the Church.
66. The mystery of the most Holy Eucharist which Christ, the High Priest instituted, and which He commands to be
continually renewed in the Church by His ministers, is the culmination and center, as it were, of the Christian religion. We consider it opportune in speaking about the crowning act of the sacred liturgy, to delay for a
little while and call your attention, Venerable Brethren, to this most important subject.
67. Christ the Lord, "Eternal Priest according
to the order of Melchisedech,"(56) "loving His own who were of the world,"(57) "at the last supper, on the night He was betrayed, wishing to leave His beloved Spouse, the Church, a visible sacrifice
such as the nature of men requires, that would re-present the bloody sacrifice offered once on the cross, and perpetuate its memory to the end of time, and whose salutary virtue might be applied in remitting those sins
which we daily commit, . . . offered His body and blood under the species of bread and wine to God the Father, and under the same species allowed the apostles, whom he at that time constituted the priests of the New
Testament, to partake thereof; commanding them and their successors in the priesthood to make the same offering."(58)
68. The august
sacrifice of the altar, then, is no mere empty commemoration of the passion and death of Jesus Christ, but a true and proper act of sacrifice, whereby the High Priest by an unbloody immolation offers Himself a most
acceptable victim to the Eternal Father, as He did upon the cross. "It is one and the same victim; the same person now offers it by the ministry of His priests, who then offered Himself on the cross, the manner of
offering alone being different."(59)
69. The priest is the same, Jesus Christ, whose sacred Person His minister represents. Now the
minister, by reason of the sacerdotal consecration which he has received, is made like to the High Priest and possesses the power of performing actions in virtue of Christ's very person.(60) Wherefore in his priestly
activity he in a certain manner "lends his tongue, and gives his hand" to Christ.(61)
70. Likewise the victim is the same, namely,
our divine Redeemer in His human nature with His true body and blood. The manner, however, in which Christ is offered is different. On the cross He completely offered Himself and all His sufferings to God, and the
immolation of the victim was brought about by the bloody death, which He underwent of His free will. But on the altar, by reason of the glorified state of His human nature, "death shall have no more dominion over
Him,"(62) and so the shedding of His blood is impossible; still, according to the plan of divine wisdom, the sacrifice of our Redeemer is shown forth in an admirable manner by external signs which are the symbols
of His death. For by the "transubstantiation" of bread into the body of Christ and of wine into His blood, His body and blood are both really present: now the eucharistic species under which He is present
symbolize the actual separation of His body and blood. Thus the commemorative representation of His death, which actually took place on Calvary, is repeated in every sacrifice of the altar, seeing that Jesus Christ is
symbolically shown by separate symbols to be in a state of victimhood.
71. Moreover, the appointed ends are the same. The first of these is
to give glory to the Heavenly Father. From His birth to His death Jesus Christ burned with zeal for the divine glory; and the offering of His blood upon the cross rose to heaven in an odor of sweetness. To perpetuate
this praise, the members of the Mystical Body are united with their divine Head in the eucharistic sacrifice, and with Him, together with the Angels and Archangels, they sing immortal praise to God(63) and give all
honor and glory to the Father Almighty.(64)
72. The second end is duly to give thanks to God. Only the divine Redeemer, as the eternal
Father's most beloved Son whose immense love He knew, could offer Him a worthy return of gratitude. This was His intention and desire at the Last Supper when He "gave thanks."(65) He did not cease to do so
when hanging upon the cross, nor does He fail to do so in the august sacrifice of the altar, which is an act of thanksgiving or a "eucharistic" act; since this "is truly meet and just, right and availing
73. The third end proposed is that of expiation, propitiation and reconciliation. Certainly, no one was better
fitted to make satisfaction to Almighty God for all the sins of men than was Christ. Therefore, He desired to be immolated upon the cross "as a propitiation for our sins, not for ours only but also for those of the
whole world"(67) and likewise He daily offers Himself upon our altars for our redemption, that we may be rescued from eternal damnation and admitted into the company of the elect. This He does, not for us only who
are in this mortal life, but also "for all who rest in Christ, who have gone before us with the sign of faith and repose in the sleep of peace;"(68) for whether we live, or whether we die "still we are
not separated from the one and only Christ."(69)
74. The fourth end, finally, is that of impetration. Man, being the prodigal son, has
made bad use of and dissipated the goods which he received from his heavenly Father. Accordingly, he has been reduced to the utmost poverty and to extreme degradation. However, Christ on the cross "offering prayers
and supplications with a loud cry and tears, has been heard for His reverence."(70) Likewise upon the altar He is our mediator with God in the same efficacious manner, so that we may be filled with every blessing
75. It is easy, therefore, to understand why the holy Council of Trent lays down that by means of the eucharistic sacrifice the
saving virtue of the cross is imparted to us for the remission of the sins we daily commit.(71)
