On occasion of the Feast of St. Pius V, you may want to feast your eyes on Quo Primum, the Apostolic Constitution with which the great, great, great Pope Saint Pius V promulgated his Missal in 1570 and established its ambit of application.
We specifically command each and every patriarch, administrator, and all other persons or whatever ecclesiastical dignity they may be, be they even cardinals of the Holy Roman Church, or possessed of any other rank or pre-eminence, and We order them in virtue of holy obedience to chant or to read the Mass according to the rite and manner and norm herewith laid down by Us and, hereafter, to discontinue and completely discard all other rubrics and rites of other missals, however ancient, which they have customarily followed; and they must not in celebrating Mass presume to introduce any ceremonies or recite any prayers other than those contained in this Missal.
Pope Saint Pius V apparently didn’t do “encouragement” much. He doesn’t suggest, he commands. The language is brutally frank: the priest “must not presume”, other rubrics and rites are to be “completely discarded”.
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.
Note here how the Pope protects not only the Liturgy from bad priests, but the priests from bad bishops: No one can be forced or coerced to alter the missal. Also note the extremely strong words: this present document cannot be revoked or modified. Don’t ask me what I think this great Pope would think of the liturgical reforms of the Sixties…
We decree that, after We publish this constitution and the edition of the Missal, the priests of the Roman Curia are, after thirty days, obliged to chant or read the Mass according to it; all others south of the Alps, after three months; and those beyond the Alps either within six months or whenever the Missal is available for sale. Wherefore, in order that the Missal be preserved incorrupt throughout the whole world and kept free of flaws and errors, the penalty for nonobservance for printers, whether mediately or immediately subject to Our dominion, and that of the Holy Roman Church, will be the forfeiting of their books and a fine of one hundred gold ducats, payable ipso facto to the Apostolic Treasury
Splendid again: a very short time for the implementation of the new Missal, after it has become available. Similarly, the immediate threat of hefty fines for the transgressors.
