Hitler was acutely aware that Christianity posed a threat to his authority as it taught peace and tolerance, which contradicted the Nazis' beliefs about strength and violence
In the early part of Hitler's Reich, the Nazis tried to work with the churches, but soon the contradiction of their aims became a problem and Hitler turned on them
Hitler drew up a Concordat with the Pope in July 1933, promising to allow Catholics to worship freely and Catholic schools to teach their own curriculum, but he did not keep these promises
In 1937, churches that had supported the Nazis or thought it was better to work with them joined together to become the Reich Church, led by Ludwig Muller
The Reich Church was not allowed to let Jews convert or be baptized into the church, and Jewish teachings in the Old Testament were deleted from the Bibles
Some members of the Christian faith resisted the changes by speaking out or refusing to participate in Nazi rules, while a few actively opposed the Nazis
Despite the risks, some religious leaders stood against the Nazis, with groups like the Pastors' Emergency League opposing the joining of Protestant churches into the Reich Church and the removal of Jewish texts in the Old Testament
