Peter Kramer (priest)

Peter Kramer (born 1955) is a Roman Catholic priest and theologian, known primarily for his traditionalist views within the Catholic Church, particularly his adherence to Sedevacantism. Sedevacantism is the belief that the papacy has been vacant since the death of Pope Pius XII in 1958, or at the latest, since the Second Vatican Council (1962-1965). Kramer and his followers believe that the post-conciliar popes have promulgated heresy and therefore could not be true popes.

Ordained in 1982, Kramer's ministry has been characterized by a defense of traditional Catholic doctrine and liturgy. He has authored several books and articles criticizing the changes implemented after Vatican II, arguing that they represent a departure from authentic Catholic teaching. He is a vocal critic of what he perceives as modernism and liberalism within the Church.

Kramer's views are considered controversial within mainstream Catholicism. He is not affiliated with the Roman Catholic Church or any of its recognized dioceses or orders, as his Sedevacantist position places him outside of communion with the current papacy. He operates independently, offering sacraments and celebrating Mass according to the Tridentine Rite (also known as the Extraordinary Form of the Mass or Traditional Latin Mass). His ministry attracts individuals who share his traditionalist beliefs and reject the authority of the post-Vatican II popes.
