No doubt Hitler used religion – but keep in mind, a twisted and vague version of Christianity – to gain favor, but he persecuted Christians (meaning devout fundamentalists who rejected his fascist “religion”) to a certain degree too. That quote was stated by him in 1941 in private when amongst his Nazi cronies. I’d wager that it’s more revealing of his personal religious identity than his big speeches. That doesn’t make him an atheist, but it doesn’t make him a Christian in a traditional sense. I suspect that he planned on creating his own semi-“Christian” religion. Hell, the Nazis even cooked up their own version of Jesus who they turned into an anti-semite. I think both Catholic and Lutheran (the two main religions in Germany) hold some blame due to their nonstop mistreatment of the jews over the centuries, which no-doubt caused the anti-semitism necessary for Hitler to scapegoat the entire Jewish race.
