Priestly Fraternity of Saint Peter
Catholic society of apostolic life
The Priestly Fraternity of Saint Peter (Latin: Fraternitas Sacerdotalis Sancti Petri; FSSP; informally the Fraternity) is a traditionalist Catholic society of apostolic life for priests and seminarians. It is in communion with the Holy See. It was founded in 1988 by 12 former members of the Society of Saint Pius X (SSPX) who left following the 1988 Écône consecrations, which resulted in the SSPX bishops being excommunicated by the Holy See.
Headquartered in Switzerland, the society maintains two international seminaries: the International Seminary of St. Peter in Wigratzbad, Opfenbach, Bavaria, Germany, and Our Lady of Guadalupe Seminary in Denton, Nebraska, United States. The society is officially recognized by the Holy See and has 368 priests who celebrate the Tridentine Mass in locations in 147 worldwide dioceses.
Canonical status
According to canon law, the Petrine Fathers are part of a clerical society of apostolic life of pontifical right. It is not, therefore, an institute of consecrated life and members take no religious vows, but are instead bound by the same general laws of celibacy and obedience as diocesan clergy and, in addition, swear an oath as members of the society. The fraternity's pontifical right status means that it has been established by the Pope and is answerable only to him in terms of its operation (through the Dicastery for Institutes of Consecrated Life and Societies of Apostolic Life; prior to January 17, 2019, through the Pontifical Commission Ecclesia Dei), rather than to local bishops. A local bishop still governs the fraternity's work within his respective diocese.

Why this record matters

Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Sep 20, 2026. The linked authority identifier is Q567881. VIAF identifies the subject as 163682492. The Library of Congress control number is no00071551.
