In Brief

Summorum Pontificum (7 July 2007) is Benedict XVI’s motu proprio that broadly freed the Traditional Latin Mass, framing it and the Novus Ordo as two “uses” of the one Roman Rite and declaring the older Missal “never juridically abrogated… and, consequently, in principle, was always permitted.” For fourteen years it normalized the older Mass, and vocations and apostolates grew. Traditionis Custodes reversed the framework in 2021 — but the generation formed in those years is not unformed by an administrative act. Much of today’s traditional movement is its harvest.

What Was Summorum Pontificum?

For fourteen years it was the charter that brought the old Mass back into the open. To understand the present, you have to understand what it said — and what changed in 2021.

Quick Answer

Summorum Pontificum is the apostolic letter motu proprio issued by Pope Benedict XVI on 7 July 2007, broadly liberalizing the celebration of the Traditional Latin Mass. It was among the most consequential liturgical acts of the post-conciliar era.

Its central declaration: the Missal of St. Pius V (the TLM) and the Missal of Paul VI (the Novus Ordo) are two “uses” of the one Roman Rite — the Extraordinary Form and the Ordinary Form. The older Missal, Benedict wrote, “was never juridically abrogated and, consequently, in principle, was always permitted.” Any priest of the Latin Rite could celebrate it; where stable groups of the faithful requested it, their pastors were to provide for it.

The document mattered because, for nearly forty years after 1969, many bishops had treated the older Mass as effectively forbidden, and the Catholics who loved it were often marginalized. Summorum Pontificum normalized it as a legitimate part of the Church’s patrimony. Vocations to traditional communities grew, new apostolates opened, and diocesan parishes began adding Latin Masses to their schedules. The accompanying Letter to the Bishops set the tone: “What earlier generations held as sacred, remains sacred and great for us too.”

That framework governed until July 2021, when Traditionis Custodes reversed it. But the fourteen years in between formed a generation of Catholics in the older liturgy — and a generation formed in prayer is not unformed by an administrative act. Much of today’s traditional movement is the harvest of those years.

The Charter of the Return

Pope Benedict XVI

This Missal was never juridically abrogated and, consequently, in principle, was always permitted.

Letter to the Bishops, 2007

A reigning pope: the old Mass was never abolished

Pope Benedict XVI

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.

Letter to the Bishops, 2007

A reigning pope: the old liturgy is not a rejection to be repented of, but an inheritance

Pope Francis

The liturgical books promulgated by Saint Paul VI and Saint John Paul II… are the unique expression of the lex orandi of the Roman Rite.

Traditionis Custodes, 2021

The 2021 restriction, in its own words — the tension we name, not hide

Domus Dei

A pope of our own century called the old Mass sacred, legitimate, and never abolished. Whatever the law does next, that judgment was made — and the souls it formed cannot be un-formed by a memo.
