Nobody (almost nobody) likes Adolf Hitler. Christians say he was an atheist, atheists say he was a Christian, Jews say he was a mass murderer. But we can get at his beliefs in two ways: through his actions, and through his words.
First, he was a human. As a species humans are territorial and resource-possessive. We’ve been walking out of Africa in waves for the past 100,000 years, staking a claim to the empty places we like, pushing out the inhabitants of a previous wave, defending our turf against the next wave. We use our gods as moral justification for murder, and we glorify our massacres as historic victories.

Genocidal massacres involve killing men, women and children
The Jews took over the Promised Land of Canaan in this way, with Moses telling them that God said to kill every man, woman, child, animal and tree in the targeted cities in order “that they not pollute you with their evil ways” (Deuteronomy 20: 16-18). With these cities the soldiers weren’t even allowed to abduct the virgins, they had to kill everything.
God intervened to help Moses’ successor Joshua in the conquest, sending hailstones to kill half the enemy one time, and another time stopping the sun in the sky so Joshua could finish off the enemy before dark. (It’s surprisingly hard to find corroborating evidence from other cultures, of the spinning Earth suddenly stopping, and the oceans slopping all over the land as a result, and so on.)
And so the Jews wiped out the people there and took Palestine for themselves.
Christians, Jews and atheists… who claims that this was good?
Hitler’s actions were no worse than Moses’ or Joshua’s, and for the same reason. Genocide for the sake of ethnically uncontested control of territory and resources, and for racial purity.
Christians, Jews and atheists… who claims that this was good?
“But wait,” a Christian may say, “that was acceptable in the time before Christ, but it changed with the dispensation of the New Testament. It isn’t acceptable today.”
No way, Christian! Jesus didn’t intend any changes to the Mosaic Law: “Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill. For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.” (Matthew 5: 17-18) Any subsequent changes are the work of Paul, not Jesus.
“No, no, wait, wait,” says the religious person. “Moses and Joshua were following the mysterious commands of God for some greater hidden purpose, which Hitler wasn’t.”
You can follow a more detailed discussion of that in a different blog here, and it brings us to the second way of looking at Hitler’s beliefs: his words. Here are 19 Christian quotations from Mein Kampf, from his speeches, and even this one:
“The Catholic Church should not deceive herself: if National Socialism does not succeed in defeating Bolshevism, then Church and Christianity in Europe too are finished. Bolshevism is the mortal enemy of the Church as much as of Fascism. …Man cannot exist without belief in God. The soldier who for three and four days lies under intense bombardment needs a religious prop.” – Adolf Hitler in conversation with Roman Catholic Cardinal Michael von Faulhaber of Bavaria, November 4, 1936
In sum, Hitler was one of those Christians who wants his Christianity free of Jews. And if his actions were evil, so too were those of Moses, Joshua and God.
So don’t blame atheism for Hitler and the Holocaust. Blame Moses and God… or blame the species we call “humanity”.
