The Apostles of Jesus and Mary
Known under its public title as
Priestly Fraternity of Saint Pius X
This is the largest organization of Traditionalists in the world, with four bishops, numerous priests, many priories, seminaries, etc. Several pages are devoted to this organization here, and there are numerous websites operated by the Society of Saint Pius X, as this organization is commonly known to the world. (The above titles is taken from their statutes.) There are also many websites, both for and against this society and there is a wealth of older information, that has not been published elsewhere on the internet, that will be provided here. Fortunately the Society itself has published a great deal of information, that was previously published in The Angelus, their American publication.
