I thought that once a Catholic always a Catholic. If Hitler was baptized into the Catholic Church, rather he later renounced it or not, the Catholic Church still considered him a member. You’re not denying this most important point of Hotel Catholicfornia, are you? I know, I know, people can be excommunicated. Was he excommunicated?
I'm not positive here and God knows I'm not defending the RCC's general practices, but I do seem to remember something about Hitler being excommunicated. I may be wrong about that, but that uncertainty is what kept me from bringing this point up in my post.
