At best, we'd end up agreeing to disagree. From my POV, the errors are there. From your POV, the Church is unable to error, so anything the Church teaches has to be correct.
I have no problem agreeing to disagree. However, when someone is going to talk about “corruption” within the Church, they need to be prepared to differentiate between whether it was the Church that was corrupt or individuals.
I will NEVER deny that there were a lot of corrupt practices that individuals carried in the name of the Church in Luther’s day (and other times), I will even acknowledge that high-ranking Church officials probably turned a blind eye to them. But this is still distinct from Church teachings.
