This is a volume of sermons by a Professor at Union Theological Seminary who has become known as one of the leading exponents of the neo-orthodox school of theology. Readers of these sermons will readily detect why Professor Tillich has such a hold on his students and why he is wielding such a powerful influence in the thinking of the Protestant Church of America today. Professor Tillich reminds one of Jeremiah and Isaiah. He is a prophet of doom, a prophet of judgment -- harsh, uncompromising. Man, he says, is helpless. Human institutions are of no avail. Only God can help, only God can save. But God is available and his salvation is at hand if we would receive it. One wonders if these sermons were actually preached and if so, where and what reception was accorded them. This is strong meat and congregations accustomed to soft pablum would find it hard to swallow and harder still to digest. This is a book which will interest clergymen and theologians primarily, although its message is one which a wider circle of people need to hear, even though they may not agree with all of the author's presuppositions and conclusions.
