Karl Barth is perhaps the most influential Protestant theologian of the twentieth century. This Guide to his thought, written by one of the leading scholars of Barth, offers a concise but comprehensive introduction to his theology. The first chapter of the book considers the life and work of Karl Barth. Thereafter, the chapters examine in turn the key theological topics which Barth treated in his magnum opus, the Church Dogmatics the doctrine of the Word of God, the doctrine of God, the doctrine of creation, and the doctrine of reconciliation. In each case, the theological path which Barth follows is first traced and then illuminated, recognising key lines of critique at appropriate junctures. The final chapter considers the legacy of the work of Barth, and the book closes with a list of suggestions for further reading. This structure follows the series format of the Bloomsbury T&T Clark Guides for the Perplexed, and offer a clear and accessible introduction to Barth's thought.
