Luther was ex-communicated by the Catholic church for wanting to hold it accountable and getting rid of the corruption within..
He did not split to start a new denomination, as some Catholics here have proposed, but rather he was trying to get the Catholic church back to its roots in the Bible that Catholics claim their own church WROTE.
How dare he expect the RCC follow their (allegedly) own Scripture?
No, Luther used the corruption as cover to introduce novel, heretical doctrine. There were other prominent non-heretical scholars who were highly critical of the corruption, just as there are now.
Exactly. Luther was acting as we’re called to do - hold our fellow Christians to account for their actions. And Rome didn’t like it - so they tried to eliminate the person rather than address its error.
It is 100% scriptural to hold others - even those “above” us - to account for their actions and positions. And if the person will not repent, then THEY are to be shut out. Rome got it 100% backwards.
