In an urbane and persuasive tract for our time, the distinguished Catholic theologian combines a comprehensive metaphysics with a sensitivity to contemporary existentialist thought. Father Murray traces the problem of God from its origins in the Old Testament, through its exposition by the Christian Fathers and the definitive statement by Aquinas, to its denial by modern materialism. Since the book examines the growth of doctrine that is now, even more than in the days of Newman, a fundamental issue between Roman Catholic and Protestant, theologians and nonspecialist intellectuals alike will find the subject of vital interest. As a challenge to the ecumenical dialogue, the question is raised whether, in the course of its development through different phases, the problem of God has come back to its original position.
