Since the outbreak of the Second World War we have witnessed what may best be described as a “Renaissance of Christian Thought.” Christian belief is more respectable among intellectuals than it was a generation ago. Philosophers, novelists, and poets who present the case for Christianity are widely read and taken seriously even by fellow-intellectuals who do not share their beliefs. Among the Christian intelligentsia there has been a striking rebirth of theology, and Christian theologians are read more widely outside clerical circles than they have been for perhaps a hundred years. The names of Barth, Brunner, Nygren. Maritain, Tillich, and Niebuhr are known at least vaguely to the same sort of people who could not have named a single theologian a generation ago. Both the quality and range of the revival are impressive. Christianity appears to be attracting first-rate minds, and Christian speculation is ranging all the way from social and political theory to ethics, philosophy, and history.
