This critical study of Karl Barth's Christian theological ethics discusses Barth's controversial and characteristically misunderstood ethics of divine command. The surprising relation of his 'divine command ethics' to contemporary 'narrative theology' and 'virtue ethics' and specific moral themes concerning bonds between parents and children, the nature of truth telling, and the meaning of Christian love of God and neighbor are all discussed. This book reveals Barth's richness, depth, and insight, and places his work in constructive connection with salient themes in both Catholic and Protestant ethics. Attentive to the fullness of Barth's Christological vision and to the purposes and limits of his reflections on the Christian life in pursuit of the good, William Werpehowski also advances conversations in Christian ethics about the nature of practical deliberation and decision, the orientation and dispositions that embody moral faithfulness, and the question and features of 'natural morality.'
