This volume uncovers Barth's and Bonhoeffer's influences on one another and reads them side-by-side, revealing the insights both theologians bring to today's secular and religious context. Greggs addresses the meaning and the extent of salvation, God's relation to time and eternity, sin and confession, and inter-faith dialogue for a church that critiques its own practice of religion. This is a lively exploration of the implications of two great theologians' work for a completely secular and religious world.
