The Society of Saint Pius X (SSPX) is an international priestly fraternity of common life without vows, whose purpose is to form, support, and encourage holy priests to remain faithful to the Church's traditional and the Mass of All Time, that they may effectively and compassionately spread the one, holy, Catholic, orthodox, and Apostolic faith throughout the world. The SSPX was founded in 1970 by the French Roman Catholic Archbishop Marcel Lefebvre.
----------------------------------------- Invaluable. Especially for things like the (helpfully annotated) text of St. Ignatius' Spiritual Exercises. Other sections are also incredibly well done. Well organized, well explained. The essential prayers and devotions that a Catholic needs in this life, with a lot of extra.
