Pastor Dietrich Bonhoeffer early on saw the evil of National Socialism and Hitler. He wrote the classic, “The Cost of Discipleship.” Bonhoeffer saw the evil of Nazism and how its beliefs and influence was infiltrating the German church and how it was radically changing German society; he did his part in trying to stop Hitler and became a Christian martyr.  Discipleship, to Bonhoeffer is a high calling in Christ and a call to action.
