I really don't know a lot of the details surrounding the RCC and Germany prior to or during WWII. I think that because the RCC first became sponsored by the state and then later became the state religion and now is recognized as an independent state (the Vatican) there is a political component to it. Obviously there are times that the RCC operates in what it perceives to be it's best interest and not Christianity as a whole, but thats probably rooted in the discredited idea of exclusivity.
As a Baptist we are loosely organized and gather in associations. A very decentralized structure, similar to what you find in the early church especially during the Apostolic Era. Thus you don't see Baptist "leaders" negotiating treaties because any Baptist "leader" can't command all Baptists to do something. If we were organized in a centralized hierarchy it's possible a Baptist "leader" would be seen with a head of state.
I know its long winded, but I don't want to think that the RCC's hierarchy operated out of an anti semitic thinking. I think it's more likely that any mistakes they made were done from a desire to "protect their church". They were probably hedging their bets till they knew who would win the war. A secular, political thinking.
BTW, I'm stuck home today and saw John Macarthur. Terrific, great insight.
Interesting. Of the world.....
If you are "stuck" at home you could do much, much worse than Macarthur.
