Not to be to disagreeable, but I think they were much more into the occult. I agree the RCC made some very big mistakes leading up to the war, during the war and after the war, but wouldn't it be more accurate to ascribe those mistakes to the political nature of the RCC?
Prior to and during the initial stages of WWII they didn't know who would win and were hedging their bets. Their actions are almost always governed by "what's in the church's best interest".
