I'm sure there were a lot of Lutherans in Germany and outside of it who fought the evil of the Nazis. I suspect that a lot of Christians were blinded by the success that the Nazis had early on in rebuilding national pride and the economy and it was only later that they realized the evil that they had become a part of.

The trouble we have is in admitting the terrible mistakes the RCC has NOT made.
We don't.
This isn't one of them.
