The Nazis weren't Christians. They were racists who believed in crazy Aryan race theories that had nothing to do with Christianity. Source:

Hitler also denied that Jesus was Jewish, thus denying the Gospel from its first page (Jesus Christ, in the Flesh, was the Son of David, Son of Abraham - King David is in the Tribe of Judah, from whom the Jews come, and Abraham is the Grand-Father of Jacob, who was renamed Israel) and also rejected Paul completely.

Table Talk, Hitler praised
Julian the Apostate's
Three Books Against the Galilaeans, an anti-Christian tract from 362. In the entry dated 21 October 1941, Hitler stated: When one thinks of the opinions held concerning Christianity by our best minds a hundred, two hundred years ago, one is ashamed to realise how little we have since evolved. I didn't know that Julian the Apostate had passed on such clear-sighted judgment on Christianity[...] the Galilean, who later was called Christ, intended something quite different. The Galilean was and must always be regarded as a popular leader who took up His position against the Jews [...] and it's certain that Jesus was not a Jew. The Jews, by the way, regarded Him as the son of a whore—of a whore and a Roman soldier. The decisive falsification of Jesus's teachings was the work of St. Paul [...] or Paul of Tarsus (his name was Saul, before the road to Damascus) was one of those who persecuted Jesus most savagely.

What stupidity. So according to this apostate pagan Hitler, Jesus Christ was not Jewish. St. Paul supposedly falsified Christianity (there goes most of the Bible, including the Gospels, St. Paul's Epistles, and Hebrews where it says:
"it is evident that our Lord sprang out of Judah" i.e. was a Jew by race
(Heb 7:14) and pretty much the entire Bible). This man was not a Christian, but an Apostate who rejected Christianity together. He also praised Julian the Apostate, a Roman Emperor who apostatized from Christianity and tried temporarily to revive paganism, before God prevented that. See:
