Hitler was not a Christian. That is an absolute lie of epic proportions. He was in bed with certain figures of the Catholic Church (which keep in mind, I don’t even consider to be Christian in the first place) for political reasons, but his views of the Christian philosophy are clear:

“The heaviest blow that ever struck humanity was the coming of Christianity. Bolshevism is Christianity’s illegitimate child. Both are inventions of the Jew. The deliberate lie in the matter of religion was introduced into the world by Christianity.” - This was in 1941, after he was firmly in power and didn’t need to cater to anyone ideologically speaking.
