You owe it to yourself to buy and read "Bonhoeffer's Black Jesus" (Baylor University Press) by Reggie L. Williams. This short book is not an quick or easy read. It is chocked full of thought-provoking insights that Bonhoeffer gleaned from his year at Union Theological Seminary (NY), and especially his association with Abyssinia Baptist Church in Harlem. Bonhoeffer left America a different person than when he arrived. He was now a Christian! Without his Abyssinia experience, Bonhoeffer would not have stood with the oppressed Jews of Germany during WWII.
