the protestants in germany came up with the term to apply to themselves btw.
Could be but they/others "bought it"..
Luther protested(thesis) but Luther was a Roman Catholic priest..
Actually for a long while ALL that followed him were Roman Catholics..
Luther did not start a New cult.. he didn't even know he was already a part of a cult..
Poor old Martin Luther only partially knew he had identified the largest christian sect and actual cult ever known on this planet.. A cult of heretics exposed by the NEW TESTAMENT.. The Eastern orthodox(so-called) were only marginally better..
The Roman Catholic Church actually PROTESTS normal orthodox Christian operation as layed out IN THE BIBLE, both old and New.. This is documented not only in many many Church History's but in many Seminary's.. Before 313A.D. the RCC was locai and a curiosity..
Its all in Millers Church History.. one of the better church historys..
