Timeline: Ecclesia Dei communities, Priestly Fraternity of St. Peter (FSSP)

Pope Leo XIV received the superior general of the Priestly Fraternity of St. Peter in a private audience at the Fraternity's request, during the apostolic visitation begun in 2024; the Fraternity called the meeting cordial.

The Dicastery for Institutes of Consecrated Life and Societies of Apostolic Life announced a visitation of the FSSP, describing it as a way to know the society better and support it; the Fraternity said it did not stem from any problems. The previous ordinary visitation was in 2014.

Seven months after Traditionis custodes, Pope Francis signed a decree, made public by the FSSP on 21 February, confirming its members' faculty to use the 1962 Missal, Ritual, Pontifical and Breviary, with the local ordinary's consent required outside its own churches except for private Masses.

By its own account, the Priestly Fraternity of St. Peter was founded at the Abbey of Hauterive in Switzerland by about a dozen priests and some twenty seminarians who did not follow Archbishop Lefebvre after the 30 June consecrations; John Paul II erected it canonically the same year.
