It analyzes how German churches were complicit with or supportive of Nazi policies targeting Jews. It then draws parallels between perceived threats to Christianity in Germany and the US. The document evaluates the response of the Deutsche Christen and Confessing Church in Germany and discusses Dietrich Bonhoeffer's criticism of six ethical failures that could enable similar issues in the US regarding inclusion of Muslims.
