The Greatest "Heresy" of The Protesters seeking to Reform the Catholic paradigm was/is rejecting only some of the RCC's false doctrines, rather than all of them. Such false doctrines include baptismal regeneration, paedobaptism, considering the emblems of Christ's Passion as sacraments, a two-class clergy/laity system of government of the assembly, a bishopric external to the local church, gaining/losing/gaining/losing one's salvation ad infinitum, episcopacy, special religious dress for the clergy, female elders/pastors, etc.; to name a few unbiblical heresies.
I (and the Lutheran Church—Missouri Synod) agree with you on 2/3 of the ‘heresies’ you mention.
It’s also after midnight so I’m going to go to bed instead of get into an argument about the remaining 1/3.
I think you just about covered most of the false doctrines of the RCC. If there are others, I can’t think of any at the moment. 😁
You may have never heard of some fruitcake, that lives around here. I had never heard of the dude either, till a few years ago. He is still alive here too. His name is Apollo C Quiboloy. If there is a dictionary definition of blasphemy, his picture would be there. The dude is a total chump.
