The foundation: 1970
Archbishop Marcel Lefebvre founded the Society of Saint Pius X on November 1, 1970, after young men asked him for traditional priestly formation. Its beginnings at Ecône, Switzerland, centered on preparing priests through study, prayer, and the Traditional Latin Mass.
Difficulties and growth
The General House's account describes the 1974 seminary visitation, the Society's suppression in 1975, and Archbishop Lefebvre's suspension in 1976. It explains his decision to continue the seminary and ordinations as a defense of Catholic Tradition. New seminaries and apostolates subsequently developed beyond Switzerland.
1988 and the continuation of the apostolate
In 1988, Archbishop Lefebvre consecrated four bishops following negotiations with Rome. The SSPX's account presents his intention to preserve its priestly work. He died on March 25, 1991; the Society continued its seminaries, chapels, and religious life. The account also recalls the 2000 pilgrimage to Rome, Summorum Pontificum in 2007, and the lifting of the four bishops' excommunications in 2009.
