Was Hitler a Christian?

[abaris]

Luther's anti Jewish rhetoric still shaped Hitler's views and that does have a biblical source regardless. 

Luther shaped Hitler least of all. I would say, not at all. Look up the names I've already mentioned in this very thread. Hitler was shaped by the belle epoque antisemitism of his time, which was largely political, social and economical. Luther didn't play a role because for one, Hitler never was a protestant and secondly because the environment of Vienna and Munich was deeply catholic.

But that aside, where he got his rabid antisemitism from is still up for dispute, since it's a known and proven fact that he socialised with jews when he lived at Vienna. He emerged from the first war being an antisemite. At least he claimed to be, since before joining the DAP, which he turned into the NSDAP, he was a "Reichswehr" informant for the regime of Kurt Eisner, who besides being a radical leftist, was a jew.

What he wrote in "Mein Kampf" isn't taken to be fact. It's a legend he surrounded himself with. The poverty as well as the early antisemitism. Hitler never was really poor, since he inherited a moderate sum of money and his extended family provided for him.
