Congrégation du Saint-Esprit
SSPX was founded, with the canonical approval of the Bishop of Fribourg, in 1970 by French Archbishop Marcel Lefebvre, former Superior General of the Holy Ghost Fathers (1962-1968), a Father of the Second Vatican Council and one of the best-known prelates in Africa, where he spent much of his early pastoral ministry. He retired as head of the Holy Ghost Fathers in 1968 when the order began revisions of its constitutions, which Lefebvre considered modernist.
