Pope Francis’ decision to restrict the Traditional Latin Mass is a contentious part of his leadership in the Catholic Church.
His reasoning for this restriction stems from the concern that the use of the older form of the Catholic liturgy was causing division within the Church. Pope Francis observed that the more ancient mass was being utilized in an ideological manner, often in opposition to modernity and the Vatican II mass.
The term “mass” originates from the Latin word “missa,” which translates to “sacrifice.” It encompasses two core parts: the “Liturgy of the Word” and the “Liturgy of the Eucharist,” with the latter being revered as the holiest and most elevated form of worship in the Catholic faith.
The Latin Mass, which was formalized by Pope St. Pius V in 1570 and continues to be practiced by some Catholics today, has several key differences from the more common Vatican II mass, which was instituted in 1969. These differences include the entirety of the mass being said in Latin and the priest facing “ad orientem” (“to the east”) rather than facing the congregation.

During his 12-year pontificate, Francis took several actions to limit the use of the Latin Mass throughout the world.
“The danger today is indietrismo, the reaction against the modern. It is a nostalgic disease,” he said. “This is why I decided that now the permission to celebrate according to the Roman Missal of 1962 [the Latin Mass] is mandatory for all newly consecrated priests.”
Francis said the restriction was “necessary to stop this indietrismo, which was not in the pastoral vision of my predecessors.”
Despite this, Francis clarified that specific orders of priests, such as the Priestly Fraternity of St. Peter (FSSP), were not impacted by the restrictions.
After a 2024 meeting between Francis and Father Andrzej Komorowski, the head of FSSP, the order released a communique in which it said “in the course of the audience, the pope made it clear that institutes such as the Fraternity of St. Peter are not affected by the general provisions of the motu proprio … since the use of the ancient liturgical books was at the origin of their existence and is provided for in their constitutions.”
