Can a Pope suppress an ancient rite?

This is one of the most contested questions in current Catholic theology, and serious theologians can be found on both sides. The honest answer is: it has never happened in the history of the Church, and most traditional canonists hold that it cannot be done in the strict sense.

The argument that a Pope can suppress a venerable rite usually appeals to the universal jurisdiction of the Roman Pontiff and his sole authority over the Church’s liturgy. The argument against it appeals to a deeper principle: the Mass is not the Pope’s personal possession. It is the prayer of the Church handed down from the Apostles. Even St. Pius V, when promulgating the Roman Missal in 1570, explicitly preserved any rite of more than 200 years’ standing. He did not believe his authority extended to abolishing what the Church had received.

St. Thomas Aquinas held that the Church’s ancient liturgical traditions are protected by the principle of indefectibility — the same principle that protects the Church’s deposit of faith. Pope Benedict XVI, in the explanatory letter accompanying Summorum Pontificum, wrote: “What earlier generations held as sacred, remains sacred and great for us too, and it cannot be all of a sudden entirely forbidden or even considered harmful.” That is not a procedural ruling. It is a theological statement about what a Pope can and cannot do.

In practical terms: the TLM has been heavily restricted, but not formally abrogated. Even Traditionis Custodes does not declare it abolished. The legal landscape is harsh. The theological substance of the rite is unchanged. The Mass that nourished the saints will outlast every administrative chill.
