Hitler publically declared himself to be a Christian, used Christian language and rhetoric openly to promote Nazi ideology, and spoke openly about his vilification of atheists.

In his book Mein Kampf Hitler made numerous religious pronouncements: "Hence today I believe that I am acting in accordance with the will of the Almighty Creator: by defending myself against the Jew, I am fighting for the work of the Lord."

Before his ascension to power, Hitler stated before a crowd in Munich: "My feeling as a Christian points me to my Lord and Savior as a fighter."

In a speech delivered in Berlin, October 24, 1933, Hitler stated: "We were convinced that the people needs and requires this faith. We have therefore undertaken the fight against the atheistic movement, and that not merely with a few theoretical declarations: we have stamped it out."

Also, from a speech delivered by Hitler:

"In boundless love as a Christian and as a man I read through the passage which tells us how the Lord at last rose in His might and seized the scourge to drive out of the Temple the brood of vipers and adders. How terrific was his fight against the Jewish poison. Today, after two thousand years, with deepest emotion I recognize more profoundly than ever before the fact that it was for this that He had to shed his blood upon the Cross. As a Christian I have no duty to allow myself to be cheated, but I have the duty to be a fighter for truth and justice. ...And if there is anything which could demonstrate that we are acting rightly, it is the distress that daily grows. For as a Christian I have also a duty to my own people."

Not only did Hitler *not* base his ideas on Darwin or on the Theory of Natural Selection, but there is not even a single reference to Darwin in any of Hitler's writings. Even in the Nuremburg Trials, where they actually went through the personal libraries of Nazi leaders to find the origins of the ideas behind the Third Reich, none of Darwin's works were found, and there were no references to Darwin in any of the testimonies or transcripts whatsoever.

Even when Hitler made reference to anything resembling biological arguments for his racial ideas and policies, he clearly showed that his understanding (if you could even call it that) of the subject was psueodoscientific and Lamarckian, not Darwinian. And in numerous cases, Hitler's views on race and biology *directly contradicted* Darwin's Theory of Evolution in extremely basic and fundamental ways.

For example (from http://rationalrevolution.net/...):

-Hitler stated that "racial purity" was "God's Will". Darwin showed that there is no such thing as racial purity in the first place, and that secondly, races and species are not formed by God.

-Hitler said that segregation of species and races is a "rigid law" of nature. Darwin showed that there are no such rigid laws in nature.

-Hitler said that species only naturally mate with members of their same species. Darwin showed that many species naturally hybridize (in fact, research now shows that more than 10% of "species" hybridize in the wild).

-Hitler said that species are uniform in character. Darwin showed that there is a high degree of variation within species.

-Hitler advocated the use of race laws to favor only "Nordic" peoples. Darwin stated that no such laws should be made.

-Hitler despised sympathy and said that sympathy should not extend to all races. Darwin stated that sympathy was the highest moral value, that indeed sympathy was an important attribute for human success, and that we should extend our sympathy to all people.

-Clearly, Hitler's views reflected the traditional "pre-Darwinian" views of nature. Hitler viewed race as sacred, he viewed the Germans as "God's chosen people", and he justified racism, genocide, and eugenics through his sacred views. The sacredness of race is what made race worth fighting for to the Nazis.
