Bonhoeffer words to Niebuhr

I have come to the conclusion that I made a mistake to coming to America.  I have to live through the difficult period of our national history with the Christians in Germany.  I will have no  right to assist with the restoration of Christian life after the war in Germany if I do not share the tests of this period with my people.

(Renate Bethge, Dietrich Bonhoeffer: A Brief Life, 54)
