Papal Bull Enacting the Tridentine Mass at perpetuity
Promulgating the Tridentine Liturgy
From the very first, upon Our elevation to the chief Apostleship, We gladly turned our mind and energies and directed all our thoughts to those matters which concerned the preservation of a pure liturgy, and We strove with God’s help, by every means in our power, to accomplish this purpose. For, besides other decrees of the sacred Council of Trent, there were stipulations for Us to revise and re-edit the sacred books: the Catechism, the Missal and the Breviary. With the Catechism published for the instruction of the faithful, by God’s help, and the Breviary thoroughly revised for the worthy praise of God, in order that the Missal and Breviary may be in perfect harmony, as fitting and proper – for its most becoming that there be in the Church only one appropriate manner of reciting the Psalms and only one rite for the celebration of Mass – We deemed it necessary to give our immediate attention to what still remained to be done, viz, the re-editing of the Missal as soon as possible.
Hence, We decided to entrust this work to learned men of our selection. They very carefully collated all their work with the ancient codices in Our Vatican Library and with reliable, preserved or emended codices from elsewhere. Besides this, these men consulted the works of ancient and approved authors concerning the same sacred rites; and thus they have restored the Missal itself to the original form and rite of the holy Fathers. When this work has been gone over numerous times and further emended, after serious study and reflection, We commanded that the finished product be printed and published as soon as possible, so that all might enjoy the fruits of this labor; and thus, priests would know which prayers to use and which rites and ceremonies they were required to observe from now on in the celebration of Masses.
Let all everywhere adopt and observe what has been handed down by the Holy Roman Church, the Mother and Teacher of the other churches, and let Masses not be sung or read according to any other formula than that of this Missal published by Us.
Furthermore, by these presents [this law], in virtue of Our Apostolic authority, We grant and concede in perpetuity that, for the chanting or reading of the Mass in any church whatsoever, this Missal is hereafter to be followed absolutely, without any scruple of conscience or fear of incurring any penalty, judgment, or censure, and may freely and lawfully be used. Nor are superiors, administrators, canons, chaplains, and other secular priests, or religious, of whatever title designated, obliged to celebrate the Mass otherwise than as enjoined by Us.
We likewise declare and ordain that no one whosoever is forced or coerced to alter this Missal, and that this present document cannot be revoked or modified, but remain always valid and retain its full force notwithstanding the previous constitutions and decrees of the Holy See, as well as any general or special constitutions or edicts of provincial or synodal councils, and notwithstanding the practice and custom of the aforesaid churches, established by long and immemorial prescription – except, however, if more than two hundred years’ standing.
Therefore, no one whosoever is permitted to alter this notice of Our permission, statute, ordinance, command, precept, grant, indult, declaration, will, decree, and prohibition. Would anyone, however, presume to commit such an act, he should know that he will incur the wrath of Almighty God and of the Blessed Apostles Peter and Paul.
Given at St. Peter’s in the year of the Lord’s Incarnation, 1570, on the 14th of July of the Fifth year of Our Pontificate.
