Mediator dei
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.
60. 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 for 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]
