Hitler was born to a practising Catholic mother and an anticlerical father; after leaving home Hitler never again attended Mass or received the sacraments.[364][365][366] Speer states that Hitler made harsh pronouncements against the church to his political associates and though he never officially left it, he had no attachment to it.[367] He adds that Hitler felt that in the absence of the church the faithful would turn to mysticism, which he considered a step backwards.[367] According to Speer, Hitler believed that either Japanese religious beliefs or Islam would have been a more suitable religion for the Germans than Christianity, with its "meekness and flabbiness".[368]

Historian John S. Conway states that Hitler was fundamentally opposed to the Christian churches.[369] According to Bullock, Hitler did not believe in God, was anticlerical, and held Christian ethics in contempt because they contravened his preferred view of "survival of the fittest".[370] He favoured aspects of Protestantism that suited his own views, and adopted some elements of the Catholic Church's hierarchical organisation, liturgy, and phraseology in his politics.[371]

Hitler viewed the church as an important politically conservative influence on society,[372] and he adopted a strategic relationship with it that "suited his immediate political purposes".[369] In public, Hitler often praised Christian heritage and German Christian culture, though professing a belief in an "Aryan Jesus", one who fought against the Jews.[373] Any pro-Christian public rhetoric was at variance with his personal beliefs, which described Christianity as "absurdity"[374] and nonsense founded on lies.[375]
