In a speech to SS leaders, Himmler stressed that Christianity is diametrically opposed to the racialist worldview.

“….One part [of the German folk] still stuck in a Christian way of thinking. WE WERE NO LONGER PREPARED TO FIGHT OR SUFFER HEROICALLY FOR THIS WORLDVIEW OF CHRISTIANITY, like, say, martyrs or fanatical Christians of the Middle Ages. That’s not enough anymore. Christianity is already far too dead for that. But it is still alive enough for the German people to inhibit and hinder a clear racial way of thinking.” _______________
