This is interesting seeing as it was written at the time:
“the last war and throughout the present one, the Germans have committed atrocities which are impossible to imagine by those who have merely read or heard about them. This is not teaching hatred, but an undeniable though most unpleasant fact. Not once in either war has any section of the Lutheran clergy protested—such as have the churches of Norway and other occupied countries where the Gestapo is at least as strong as inside Germany. With the exception of a few refugee pastors in Britain, I do not know of any section of the German Protestant Confessional Church whose pastors have refused to preach, to serve, to ordain and bless the atrocities and horrors committed by the German armies and their leaders.
These facts are unpleasant and horrible. I maintain that we can understand them and explain them only if we look at the dark figure from whom the German Lutheran clergy has for four centuries taken their orders: Martin Luther. Do not defy the authorities even if they are unjust, worship war, murder and slay the enemy, pray for a German God, exterminate the Jews, praise the authorities—all this, as I tried to show, was first preached by Luther, and has been propagated ever since from Lutheran pulpits and universities...”
