“The great masquerade of evil has played havoc with all our ethical concepts. For evil to appear disguised as light, charity, historical necessity or social justice is quite bewildering to anyone brought up on our traditional ethical concepts, while for the Christian who bases his life on the Bible, it merely confirms the fundamental wickedness of evil. The ‘reasonable’ people’s failure is obvious. With the best intentions and a naive lack of realism, they think that with a little reason they can bend back into position the framework that has got out of joint.”
Dietrich Bonhoeffer, Letters and Papers from Prison (1967; 1997), p. 4.
