LOL Catholics try to tie all Protestants to either Luther or Calvin. Protestants have such a long list of evil popes to tie them to it’s hard to just pick one.
...their entire indoctrination is based on compartmentalized instruction, not just to the Pope. Certain things "belong" here or there pending on who authorizes it's legitimacy. Rather similar to Islam...the Koran is not sufficient of itself...therefore 'other' writings Haddiths etc. are incorporated and interpreted by their Imams....who must be obeyed. Thank the Lord we are "free" to walk by faith and are justified fully in Him!
