Religious beliefs need to stop.

[Sword of Christ]

"The dogma of Christianity gets worn away before the advances of science. Religion will have to make more and more concessions. Gradually the myths crumble. All that's left is to prove that in nature there is no frontier between the organic and the inorganic. When understanding of the universe has become widespread, when the majority of men know that the stars are not sources of light but worlds, perhaps inhabited worlds like ours, then the Christian doctrine will be convicted of absurdity." Adolf Hitler

"What nonsense! Here we have at last reached an age that has left all mysticism behind it, and now [Himmler] wants to start that all over again. We might just as well have stayed with the church. At least it had tradition. To think that I may some day be turned into an SS saint! Can you imagine it? I would turn over in my grave..." Adolf Hitler

"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 judgment with such clear-sightedness on Christianity and Christians.... the Galilean, who later was called the Christ, intended something quite different. He must be regarded as a popular leader who took up His position against Jewry... 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 doctrine was the work of St. Paul.... Paul of Tarsus (his name was Saul, before the road to Damascus) was one of those who persecuted Jesus most savagely." Adolf Hitler

"The political leader should not estimate the worth of a religion by taking some of its shortcomings into account, but he should ask himself whether there be any practical substitute in a view which is demonstrably better. Until such a substitute be available only fools and criminals would think of abolishing the existing religion." Adolf Hitler

"What we must fight for is to safeguard the existence and the reproduction of our race ... so that our people may mature for the fulfillment of the mission allotted it by the creator of the universe. ... Peoples that bastardize themselves, or let themselves be bastardized, sin against the will of eternal Providence." Adolf Hitler

I can't find the quote on Islam but he preferred it over Christianity and thought it a shame that the Muslims hadn't conquered Europe in the dark ages. He had an idea that the Muslims being ill adapted to the European climate and generally racially inferior overall would have died out leaving a strong Germanic Islamic empire ruled from Europe. The Nazi movement essentially was a religious movement in it's own right and Hitler was it's prophet.
