Well then why dont you tell us the “name” of the person who founded the Catholic Church? You cant!
But, I can give you the name of people who started all the protestant churches.
What are you talking about? I do not support the Catholic Church. I have no idea who founded it. Probably emperor Constantine after he made it the state Church.
the person who founded the Catholic Church would be Contantine the Great, who may have been uncertain about one G-d, but was pretty darned sure about One Empire and One Emperor.
