After the '' Machtergreifung '' in 1933 , Leo , himself a Lutheran pastor of Jewish extraction , concerned himself with the topic of “ Jewish Christians ” and their place in German society . With the support of Bishop August Marahrens he developed ideas which he presented in lectures all over Germany during the following years . He insisted that Jews and non-Jews were inseparable as far as the church was concerned and that hatred of Jews was incompatible with Christianity . These beliefs put him in contact with the Confessing Church . In his May 1933 article Church and Judaism , he says : In March 1938 the Church of Hannover forced Paul Leo into retirement . Starting April 6 he gave up his pastorate in Osnabrück-Haste . He joined the underground as an instructor for the Confessional Church . During Kristallnacht ( November 9 , 1938 ) , he was arrested and incarcerated in Buchenwald concentration camp . After six weeks of physical and psychological torture , he was freed at the end of December and told he had two months to settle his affairs and leave Germany
