“Oh look, here’s our dear vlad again donning the mantle of Defender Of The Faith and pretending to know all things Protestant as well!”
Luther was the father of Protestantism. That is not a statement about all things or a claim to know all things on my part. It’s just obviously true. There were no Protestants before Luther.
And, if I am “donning the mantle of Defender Of The Faith and pretending to know all things Protestant”, then what are you donning and pretending at by denying historical facts? You can’t even see your hypocrisy can you?
But there was Protestant soteriology, like in Augustine, Chrysostom, and also even in contrary views of what the Papacy is.
Protestantism is not defined by you nor is it defined by the Roman Catholic Church, any more than the Roman Catholic Church is defined by Protestants, but that’s never stopped you. Can you see the hypocrisy? For some strange reason, it seems that you just can’t.
