Hitler on Judaism National Socialist ideology developed a racial hierarchy which placed minority groups – most especially the Jews – as subhuman. The categorization was based on the Nazi conception of race, and not on religion, thus Slavs and Poles (who were overwhelmingly Christian) were also grouped as inferior to the so-called "Aryan" peoples. Hitler espoused a ruthless policy of "negative eugenic selection", believing that world history consisted of a struggle for survival between races, in which the Jews plotted to undermine the Germans, and inferior groups like Slavs and defective individuals in the German gene pool, threatened the Aryan "master race". However, Hitler also had ideological objections to Judaism as a faith, and some of Hitler's antipathy towards Pauline Christianity (as opposed to his "Nordic Jesusism") flowed from its Jewish origins, as he saw (Pauline) Christianity as "indelibly Jewish in origin and character" and a "prototype of Bolshevism", which "violated the law of natural selection". Writing for the public in Mein Kampf, Hitler described the Jews as enemies of all civilization and as materialistic, unspiritual beings: "His life is only of this world, and his spirit is inwardly as alien to true Christianity as his nature two thousand years previous was to the great founder of the new doctrine." In the work, he also described a supposedly divine mandate for his anti-Semitism: "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." During negotiations for the Concordat between the Catholic Church and Germany in 1933, Hitler said to Bishop Wilhelm Berning: "I have been attacked because of my handling of the Jewish question. The Catholic Church considered the Jews pestilent for fifteen hundred years, put them in ghettos, etc, because it recognised the Jews for what they were. In the epoch of liberalism the danger was no longer recognised. I am moving back toward the time in which a fifteen-hundred-year-long tradition was implemented. I do not set race over religion, but I recognise the representatives of this race as pestilant for the state and for the church and perhaps I am thereby doing Christianity a great service by pushing them out of schools and public
