I stumbled across Sources telling he rejected Christianity in Private and saw no future for Religion in the Reich after the war. Now, while the debate if claming to be christian is enough to be one probably belongs to a philosophical Topic and not here, I am interested in what was actual belief and what was tactics. (I do not have any interest in pushing him away from Christianity for Reasons of own belief, just saying in advance)
Always more to be said, but do check out the section of the FAQ about Hitler's religious beliefs!
