Priestly Fraternity of St. Peter
According to the laws of the Catholic Church, the F.S.S.P. is a "Clerical Society of Apostolic Life of Pontifical Right". This means that members have to follow the same rules as diocesan clergy and also swear an oath as members of the Society. The Fraternity was established by the Pope, and local bishops are not allowed to tell the Fraternity what to do. Instead, the Pope is in charge of them, through an organization called Ecclesia Dei. A local bishop is still in charge of the Fraternity's work within his own diocese.
