Hitler denounced the Old Testament as "Satan's Bible" and utilising components of the New Testament he attempted to prove that Jesus was both an Aryan and an antisemite by citing passages such as John 8:44 where he noted that Jesus is yelling at "the Jews", as well as saying to them "your father is the devil" and the Cleansing of the Temple, which describes Jesus' whipping of the "Children of the Devil".[209] Hitler claimed that the New Testament included distortions by Paul the Apostle, who Hitler described as a "mass-murderer turned saint".[209] In their propaganda, the Nazis utilised the writings of Martin Luther, the Protestant Reformer. They publicly displayed an original edition of Luther's On the Jews and their Lies during the annual Nuremberg rallies.[210][211] The Nazis endorsed the pro-Nazi Protestant German Christians organization.
Remarkably, there were instances of individual resistance and collective efforts at fighting back inside Auschwitz. Poles, Communists and other national groups established networks in the main camp. Some Jews assaulted Nazi guards, even at the entrance to the gas chambers. In October 1944, the Sonderkommando crew at crematoria IV revolted and destroyed the crematoria. It was never used again.
Heinrich Himmler's Schutzstaffel (SS) took full control of the police and the concentration camps throughout Germany in 1934–35.[5] Himmler expanded the role of the camps to hold so-called "racially undesirable elements", such as Jews, Gypsies/Romanis/Sintis, Serbs, Poles, disabled people, and criminals.[6][7][8] The number of people in the camps, which had fallen to 7,500, grew again to 21,000 by the start of World War II[9] and peaked at 715,000 in January 1945.[10]
