Everything in this story — the monastic renewal, the capture of the movement, the warnings of Pius XII, the careful text of the Council, the labors of the Consilium — converges on a single date. On April 3, 1969, by the Apostolic Constitution Missale Romanum, Pope Paul VI promulgated the Novus Ordo Missae, the new Order of Mass. With the typical edition of 1970 it became the ordinary form of Catholic worship across the Latin Church.

What had been made was not a revision but a new rite. And the reaction — from cardinals, scholars, and the pope himself — leaves no doubt that everyone understood the magnitude of what was happening.

What Was Removed

The differences between the 1962 Missal and the 1969 Order of Mass are not matters of interpretation; they are matters of fact, verifiable by setting the two rites side by side. The most significant are these. The Offertory was replaced. The old rite’s quiet, explicitly sacrificial prayers — Suscipe, sancte Pater, in which the priest offers “this immaculate host… for my innumerable sins” — gave way to a new “Preparation of the Gifts” modeled on a Jewish table blessing: “Blessed are you, Lord God of all creation, for through your goodness we have received the bread we offer you: fruit of the earth and work of human hands.” The fact of the change is undisputed; its theological weight is precisely what is debated. The Prayers at the Foot of the Altar were removed. The dialogue built on Psalm 42 — Introibo ad altare Dei, “I will go to the altar of God” — that had opened the traditional Mass was gone. The Last Gospel was removed: the reading of the Prologue of St. John, “In the beginning was the Word,” with which the old Mass closed, no longer appears. The Confiteor was simplified and the longer list of named saints shortened, the doubled form reduced to one. And the priest’s many signs of the cross and genuflections over the offerings were sharply reduced. None of this is contested as fact, and the reformers had their stated reasons: a simpler, shorter, more intelligible rite, more accessible to modern congregations and closer, as they understood it, to ancient models. What the traditional movement insists upon is that these were not neutral tidyings — the elements removed were precisely those that most explicitly expressed the Mass as the priest’s sacrifice for sin, offered to God. Strip the sacrificial emphasis and the penitential approach, and what remains can too easily be received as a communal meal rather than a sacrifice. One thing must be said plainly here, because it is the floor on which this entire series stands: none of this touches the validity of the new Mass. The reformed rite is a valid and licit Mass of the Catholic Church, in which the same Lord is truly offered and truly received; this series has never suggested otherwise, and never will. The objection is not that the Novus Ordo is no Mass. It is that its lex orandi — the law of prayer that forms the law of belief — gives less full and less explicit voice to the faith than the rite it displaced. The doctrine was not denied; but it was, in the texture of the prayers themselves, more faintly expressed.

The Shock of the Fathers

The reaction came quickly and from the highest levels. On September 25, 1969 — days before the new rite took force — Cardinals Alfredo Ottaviani and Antonio Bacci transmitted to Paul VI a Short Critical Study of the New Order of Mass, drafted by a group of Roman theologians. Its central charge was grave and exact, and it framed the entire controversy that has followed: Notice who is speaking. Not schismatics, not cranks — two cardinals of the Roman Church, a future pope who would one day reign as Benedict XVI, and Paul VI himself, the very pope who promulgated the reform. The traditional case does not rest on the testimony of its partisans. It rests, in large part, on the words of the men who made and approved the change. In fairness, none of these men concluded that the new Mass was invalid — and Cardinal Ratzinger least of all. As Pope Benedict XVI he would celebrate the reformed rite, defend its legitimacy, and labor to reconcile it with the old. His lament, like Paul VI’s own misgiving, was for the manner of the reform and for what it set aside — not a denial that what remained was truly and fully the Mass.

The Pope Who Knew

It is Paul VI’s own candor that is most arresting. In the general audience of November 26, 1969, preparing the faithful for the new rite, he did not pretend that nothing important was happening. He spoke of “a change in a venerable tradition that has gone on for centuries,” of touching a “hereditary religious patrimony” that “seemed to enjoy the privilege of being untouchable and settled.” He spoke of the old Mass as having “seemed to bring the prayer of our forefathers and our saints to our lips.” This is not the language of a man making a minor adjustment. It is the language of a man who knows he is doing something vast, and feels the weight of it. Whatever one concludes about the reform, Paul VI cannot be accused of hiding its scale. He named it himself. And so the deed was done. The rite of Gregory, of Trent, of the martyrs and the missionaries and the saints, was set aside as the Church’s ordinary worship and a new Order of Mass put in its place. The question that remained — the question that is still unresolved — was what would become of those who could not, in conscience, let the old Mass die.
