This original and perceptive study draws out the relevance of Jacques Derrida's thought about 'deconstruction, differance' and the gift for Karl Barth's Church Dogmatics. These are particularly important for apprehending Barth's doctrine of salvation, which is the particular focus of this book. Derrida's insights are also shown to illuminate the way in which Barth speaks of complex events such as revelation which cannot be thematised by rational thought. This significant interpretation of Karl Barth indicates his affinity with postmodern thought. It will be of interest to those who are studying the relationship between theology and postmodernism, particularly the complex borders between the thematisable and non-thematisable.
