On the other hand, one can historically make the claim that all the Protestant denominations, and all their derivative streams were "invented" in the 16th, 17th, 18th, 19th, and 20th Centuries, with more "inventing" to follow. That leaves only the Orthodox (Catholic) churches going back to the beginning.
Which then means the Roman rite is not the one true church to which one must belong and pledge fidelity in order to be saved.
So which is the one true Catholic church?
