After losing his position as the superior general of the Congregation
of the Holy Spirit and watching many of the documents passed at the Second
Vatican Council go against his conscience, Lefebvre was approached by others in
the traditionalist movement and asked to open a conservative seminary. He
received permission from the bishop of Fribourg, Switzerland and opened a small
seminary in Econe. In 1970, he established a society of priests called the
International Priestly Society of Saint Pius X (SSPX). Pius X was chosen as the
patron because of his opposition to socialism and his anti-modernist stance.
The society initially received episcopal blessing and adhered to call canonical
norms. Additional seminaries were opened in Michigan in 1973 and Rome in 1974.
The society focused on the formation of priests, believing well-formed,
traditional priests was the most effective means at reforming the Church and
society. It viewed the Second Vatican Council critically, believing it to be in
line with the modernist and socialist movements of the 20th century, which they
believed caused religious and social decline. The society does not outright
reject the council, but it questions and even dismisses many of the council’s
documents, especially those regarding religious tolerance, ecumenicism, unity,
and liturgy.
SSPX is probably best known for its opposition to the liturgical changes of the Second Vatican Council. The New Roman Missel was published in 1970, which made significant changes to the prayers and readings of the Mass and allowed for the use of vernacular language, ad populum positioning, new music, and greater congregational participation. The society rejects the legitimacy of the post-conciliar Mass and openly expresses doubt of the validity of the universal Mass celebrated by more than a billion Catholics. Therefore, the society celebrates the Mass according to pre-conciliar missals.
