A fresh and up-to-date account of the ethical thought of one of the twentieth century's greatest theologians, Karl Barth. Dr Biggar recovers Barth's ethics from some widespread misunderstandings, and goes on to relate Barth's ideas to many of the central issues debated in contemporary Christian ethics - including the concept of human freedom and of created moral order; moral norms and their relation to individual vocation; the relative ethnical roles of the Bible, the Church, philosophy, and empirical science; moral character and its formation; and the problem of war.
