Karl Barth (1886-1968) was the most prolific theologian of the twentieth century. Avoiding simple paraphrasing, Dr Gorringe places the theology in its social and political context, from the First World War through to the Cold War by following Barth's intellectual development through the years that saw the rise of national socialism and the development of communism. Barth initiated a theological revolution in his two Commentaries on Romans, begun during the First World War. His attempt to deepen this during the turbulent years of the Weimar Republic made him a focus of theological resistance to Hitler after the rise to power of the Nazi party. Expelled from Germany, he continued to defy fashionable opinion by refusing to condemn communism after the Second World War. Drawing on a German debate largely ignored by Anglo-Saxon theology Dr Gorringe shows that Barth responds to the events of his time not just in his occasional writings, but in his magnum opus, the Church Dogmatics. In conclusion Dr Gorringe asks what this admittedly patriarchal author still has to contribute to contemporary theology, and in particular human liberation.
