fixity of species and separate creation:
"The Jews are undoubtedly a race, but not human. They cannot be human in the sense of being an image of God, the Eternal. The Jews are the image of the Devil. Jewry means the racial tuberculosis of the nations." - Adolf Hitler, during a speech. May, 1923
Nothing here about "fixity of species" at all. Sorry. And referring to Jews as subhuman could just as well mean that they are some relic of prehuman evolution (not that he says that--it's all crackpot stuff anyway).
What we really see here is a master demagogue using phrases which he knows will resonate in terms of the culture of his audience-- taking religious-sounding phrases out of context and warping them into something totally opposed to their original meaning. In fact, orthodox Christians would say this is exactly how Satan works, not by frontal attack, but by confusing people with rhetorical tricks (not unlike some of the posters here).
Certainly there is nothing here suggesting that Hitler was a Christian. Quite the contrary, in fact.
This stuff does sound a lot like Calypso Louie or Ahmedinejad, by the way.
