Society of Saint Pius X

Traditionalist Catholic group.

The Society of Saint Pius X is a traditionalist Catholic organization founded in 1970 by Archbishop Marcel Lefebvre. Considered schismatic by the Catholic Church, the society comprises priests and seminarians and is associated with a worldwide network of chapels, schools, religious communities, and lay supporters. It is known for its opposition to several reforms associated with the Second Vatican Council. Members are commonly called Lefebvrists, Lefebvrians, or Lefebvrites, terms SSPX rejects. Following decades of canonical disputes, the Holy See formally declared the society to be in schism and its adherents excommunicated in July 2026 following illicit consecrations of bishops.
