There was no other church until Luther did his thing. Everything was Catholic. Please check your history.
Well actually I know my history well there were Coptic Christians and Eastern Orthodox but I’m not saying they didn’t carry the water for a long time but they slaughtered Jews and made many mistakes. No person is perfect no organization is perfect either. The reformation was a restoration of the truth. I have read the Gospels and have no doubts about what’s coming sorry bout punctuation on a phone... Many Protestant denominations are dead wrong as well
