told his inner circle that though he "did not want a 'Church struggle' at this juncture", he expected "the great world struggle in a few years' time". Nevertheless, wrote Kershaw, Hitler's impatience with the churches "prompted frequent outbursts of hostility. In early 1937 he was declaring that 'Christianity was ripe for destruction', and that the Churches must yield to the "primacy of the state", railing against any compromise with "the most horrible institution imaginable". Priests were frequently denounced, arrested and sent to concentration camps. At Dachau, the regime established a dedicated Clergy Barracks for church dissidents. The Confessing Church seminary was banned. Its leaders, like Dietrich Bonhoeffer, were arrested. Implicated in the 1944 plot to assassinate Hitler, he was later executed.

Bullock wrote "once the war was over, Hitler promised himself, he would root out and destroy the influence of the Christian Churches".

In its brief of evidence for the Nuremberg trials concerning the Nazi persecution of the churches, the American Office of Strategic Services (a forerunner to the CIA) compiled a report entitled
