In 1937, Hanns Kerrl, Hitler's Minister for Church Affairs, explained "positive Christianity" as not "dependent upon the Apostles' Creed", nor in "faith in Christ as the son of God", upon which Christianity relied, but rather, as being represented by the Nazi Party: "The Fuehrer is the herald of a new revelation", he said.[162]

In 1937, the Nazis banned any member of the Hitler Youth from simultaneously belonging to a religious youth movement. Religious education was not permitted in the Hitler Youth and by 1939, clergymen teachers had been removed from virtually all state schools.[164] Hitler sometimes allowed pressure to be placed on German parents to remove children from religious classes to be given ideological instruction in its place, while in elite Nazi schools, Christian prayers were replaced with Teutonic rituals and sun-worship.[165] By 1939 all Catholic denominational schools had been disbanded or converted to public facilities.[166]

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 ...

I want to differentiate here between the Volk, i.e. the healthy, full-blooded mass of Germany loyal to the Volk, and a decadent, so-called high society, unreliable because only conditionally linked by blood. It is sometimes casually referred to as the 'upper class,' being, however, in reality no more than the scum produced by a societal mutation gone haywire from having had its blood and thinking infected by cosmopolitism. In this period of the most inward orientation, Christian mysticism demanded an approach to the solution of structural problems and hence to an architecture whose design not only ran contrary to the spirit, of the time, but which also helped produce these mysterious dark forces which made the people increasingly willing to submit themselves to cosmopolitism ... This philosophy does not advocate mystic cults, but rather aims to cultivate and lead a Volk determined by its blood. [–] Therefore we do not have halls for cults, but halls for the Volk. Nor do we have places for worship, but places for assembly and squares for marches. We do not have cult sites, but sports arenas and play areas. And it is because of this that our assembly halls are not bathed in the mystical twilight of cult sites but rather are places of brightness and light of a beautiful and practical nature. In these halls, no cult rituals take place, they are exclusively the site of Volk rallies of the type which we conducted in the years of our struggle, which we have become accustomed to, and which we shall preserve in this manner. We will not allow mystically-minded occult folk with a passion for exploring the secrets of the world beyond to steal into our Movement. Such folk are not National Socialists, but something else – in any case, something which has nothing to do with us. At the head of our program there stand no secret surmisings but clear-cut perception and straightforward profession of belief. But since we set as the central point of this perception and of this profession of belief the maintenance and hence the security for the future of a being formed by God, we thus serve the maintenance of a divine work and fulfill a divine will – not in the secret twilight of a new house of worship, but openly before the face of the Lord.[170]

[The Führer] hates Christianity, because it has crippled all that is noble in humanity. According to Schopenhauer, Christianity and syphilis have made humanity unhappy and unfree. What a difference between the benevolent, smiling Zeus and the pain-wracked, crucified Christ. ... What a difference between a gloomy cathedral and a light, airy ancient temple. ... The Führer cannot relate to the Gothic mind. He hates gloom and brooding mysticism. He wants clarity, light, beauty. And these are the ideals of life in our time.[171]

"The Mohammedan religion would have been much more compatible to us than Christianity. Why did it have to be Christianity with its meekness and flabbiness?"[215] "Had Charles Martel not been victorious at Poitiers – already, you see, the world had fallen into the hands of the Jews, so gutless a thing was Christianity! – then we should in all probability have been converted to Mohammedanism, that cult which glorifies heroism and which opens the seventh Heaven to the bold warrior alone. Then the Germanic races would have conquered the world. Christianity alone prevented them from doing so."

Hitler's interest was opportunistic: "From Hitler's point of view, a national church was of interest purely from a point of view of control and manipulation", wrote Kershaw.[263] He installed his friend Ludwig Müller as leader of the movement and sought to establish a pro-Nazi and anti-Semitic unified Reich Church.[264] Resistance quickly arose in the form of the Pastors' Emergency League, led by Martin Niemöller, which had 40% of clergy by 1934 and founded the Confessing Church, from which some clergymen opposed the Nazi regime.[265]

When German Christians called for rejection of the Bible as "Jewish superstition" and of the Christian calling to "love thy neighbour", the movement lost still further support. Hitler's move to have Müller elected Bishop failed – despite intimidation. He then abandoned his efforts to unite the Protestant churches, appointed Hanns Kerrl as Minister for Church Affairs in December 1934, and distanced himself permanently from the so-called "German Christians".[253][266] According to Steigmann-Gall, he regretted that "the churches had failed to back him and his movement as he had hoped".[267] A relative moderate, Kerrl initially had some success but amid continuing protests by the Confessing Church against Nazi policies, he accused dissident churchmen of failing to appreciate the Nazi doctrine of "Race, blood and soil". Kerrl said Nazi positive Christianity rejected the Apostles' Creed and Divinity of Christ as the basis of Christianity, and called Hitler the herald of a new revelation.[162] Hitler had Niemöller sent to the concentration camps in 1938, where he remained until war's end.[268]

Hitler again told his inner circle that though he "did not want a 'Church struggle' at this juncture", he expected "the great world struggle in a few years' time". Nevertheless, wrote Kershaw, Hitler's impatience with the churches "prompted frequent outbursts of hostility. In early 1937 he was declaring that 'Christianity was ripe for destruction', and that the Churches must yield to the "primacy of the state", railing against any compromise with "the most horrible institution imaginable". Priests were frequently denounced, arrested and sent to concentration camps.[271] At Dachau, the regime established a dedicated Clergy Barracks for church dissidents.[272][273] The Confessing Church seminary was banned. Its leaders, like Dietrich Bonhoeffer, were arrested. Implicated in the 1944 plot to assassinate Hitler, he was later executed.[274]

Overy wrote that Christianity was ultimately as incompatible with Nazism as it was with Soviet Communism and that "Hitler expected the end of the disease of Christianity to come about by itself once the falsehoods were self-evident. During the war he reflected that in the long run 'National Socialism and religion will no longer be able to exist together'."[268] Other historians have written of a more active intent on the part of Hitler and the Nazi leadership.[29] Kershaw noted that Hitler's scheme for the Germanization of Eastern Europe saw no place for Christian churches and that Goebbels wrote from conversations with Hitler that there was an insoluble opposition between the Christian and a Germanic-heroic world-view which would need settling after the war.[275] Speer noted in his memoir that churches were not to receive building sites in Hitler's new Berlin.[276] Bullock wrote "once the war was over, Hitler promised himself, he would root out and destroy the influence of the Christian Churches".[30] The Nazi plan was to "de-Christianise Germany after the final victory", writes historian of German Resistance Anton Gill.[277] "By the latter part of the decade of the thirties church officials were well aware that the ultimate aim of Hitler and other Nazis was the total elimination of Catholicism and of the Christian religion. Since the overwhelming majority of Germans were either Catholic or Protestant this goal had to be a long-term rather than a short-term Nazi objective", wrote Michael Phayer.[278]

"Christianity is a rebellion against natural law, a protest against nature. Taken to its logical extreme, Christianity would mean the systematic cultivation of the human failure... it's not opportune to hurl ourselves now into a struggle with the Churches. The best thing is to let Christianity die a natural death. A slow death has something comforting about it. 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."

It goes on, in fact, but there's a character limit for comments. Not sure what more you want other than Hitler's own words, accounts of allies and enemies, and actual practical action of the Nazi regime at Hitler's behest.
