I am not Lutheran. Martin Luther WAS a Roman Catholic, having been raised and indoctrinated into that cult. BUT, he recognized the massive errors that the RCC was promulgating, and posted his theses.
What is LOL, is that so many Roman Catholic cultists try to answer any question against their heretical cult with "Martin Luther"...blah, blah, blah...
Roman Catholicism has little to do with reality! It is 10% truth covered with 90%fake ritual and non-Scriptural "traditions of men", i.e.: a cult!
