Society of St. Pius X

The Society of St. Pius X (SSPX) is a traditionalist Catholic priestly society founded in 1970 by Archbishop Marcel Lefebvre. It was established in response to changes in the Catholic Church following the Second Vatican Council (1962-1965), which some members viewed as a departure from traditional beliefs and practices. The SSPX emphasizes the preservation of pre-Vatican II theology, liturgy, and discipline, advocating for a return to what it considers authentic Catholicism. The society has faced ongoing tensions with the Vatican regarding its status and teachings, particularly concerning issues of authority and obedience within the Church.
