How can religion speak to the millions of men and women who have irretrievably lost their belief in a supernatural God? This is the fundamental challenge that all of the great religions of mankind face in the twentieth century. Rabbi Cohen responds to the challenge with a carefully reasoned analysis. Cohen also lays to rest some popularly held misconceptions about the nature of religion and treats the concept of God with a clarity altogether lacking in current theological writings. He demonstrates that religion, far from being identified with supernaturalism, must now function with a naturalist view of reality and of human existence.
