Ethics in Crisis offers a constructive proposal for the shape of contemporary Christian ethics drawing on a new and persuasive interpretation of the ethics of Karl Barth. David Clough argues that Karl Barth?s ethical thought remained defined by the theology of crisis that he set out in his 1922 commentary on Romans, and that his ethics must therefore be understood dialectically, caught in an unresolved tension between what theology must and cannot be. Showing that this understanding of Barth is a resource for contemporary constructive accounts of Christian ethics, Clough points to a way beyond the idolatry of ethical absolutism on the one hand, and the apostasy of ethical postmodernism on the other.
