The Priestly Fraternity of Saint Peter (Latin: Fraternitas Sacerdotalis Sancti Petri; FSSP) is a traditionalist Catholic society of apostolic life for priests and seminarians which is in communion with the Holy See.
The society was founded in 1988 by 12 clerics who were formerly members of the Society of Saint Pius X (SSPX), another traditionalist organization, but were unwilling to remain part of it following the Écône consecrations, which resulted in its bishops being declared as 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 its priests celebrate the Tridentine Mass in locations in 147 worldwide dioceses.
