Bonhoeffer's theological brilliance, committed discipleship, ecumenical insight and courageous participation in the struggle against Nazism have profoundly shaped contemporary Christian understanding and action. Although his early death at the hands of the Gestapo prevented him from providing us with a full and systematic theology, his writings are remarkably extensive and have become increasingly influential. This volume concentrates on the key texts and ideas in Bonhoeffer's thought. It presents the essential Bonhoeffer for students and the general reader.
