Wikipedia is not totally correct. It is not a sedevacantist group.
Definitely NOT excommunicated!
Also the SSPV just doesn't agree with the modern/vatican II changes. They stay true to the Catholic Church that Jesus Christ established.
They are affiliated with the SSPV, a sedevacantist group. They don't recognize the post-Vatican II popes.
Excommunicated for what? Staying true to the tradition of the Church while other religious congregations and orders collapsed after the "great renewal" of Vatican II?
@flos_carmeli They are? Who excommunicated them?
