Hitler repeatedly stated that he held the Biblical story of Jesus driving the moneychangers from the temple as his example of how to deal with Jews -harshly- and boasted in a 1937 speech to the Reichstag "we have eliminated atheism!"
German National Socialism was fundamentally a Christian and Christian-inspired movement. The party had the blessings of both the Catholic and Lutheran establishments, the former particularly after Pacelli disbanded the Catholic Center Party and the latter after the Godesburg Declaration.
The first silver coins minted by the new National Socialist government were 1933-dated 2 and 3 Mark pieces commemorating the 450th anniversary of Luther's birth. Luther authored the 1543 treatise "On The Jews and Their Lies", in which he said that Jews ought to be denied normal civil rights, their property seized, their books burned, and they themselves herded into forced labor camps. Hitler's "big lie" argument which appears in Chapter Ten of Mein Kampf (and which is so often falsely presented as evidence of his plan to deceive Germans) is grounded in Luther's teaching that the Jews' "big lie" was that they were of a religion rather than a distinct race.
Pius XI issued the encyclical Mit brendenner Sorge ("With deep anxiety") in 1937 in response to the arrests in Germany of many Bavarian Catholic leaders. With typical papal cant, he characterized these men and women as victims of Nazi persecution, but they were in reality members of a pedophile ring uncovered by local police.
