In June of 1939, Dietrich Bonhoeffer was safe and sound in the United States. He could have remained there but on June 20, 1939, he made the “fateful decision” to return to Nazi Germany. Why? In a letter to Reinhold Niebuhr, he gave the following explanation:

I have made the mistake in coming to America. I must live through this difficult period of our national history with the Christian people of Germany. I will have no right to participate in the reconstruction of Christian life in Germany after the war if I do not share the trials of this time with my people…Christians in Germany will face the terrible alternative of either willing the defeat of their nation in order that Christian civilization may survive, or willing the victory of their nation and thereby destroying civilization. I know which of these alternatives I must choose, but I cannot make this choice in security.
