I don’t know if you’re being sarcastic, but the SSPX identifies itself as an order within the Latin Rite.
Not being sarcastic...really.
It’s just I see SSPX members here tell us the true Church is with them and VAT2 is error (some even hint heresy). Then we have the Greek, Russian, Coptics saying they are really the true Church.
One Greek Orthodox member told me what he learned from a priest. That there are many ships on the waters to salvation and only the Orthodox church is the true ship. The other ships are all trying to make port but they fight the current and have a larger chance of shipwreck. But the Orthodox ship will make port because they are the True, Holy and Apostolic Church.
