This is a collection of sermons. The first one begins: "The mysteries of the Church, a materialistic scientist once announced to an astonished world, are child's play compared with the mysteries of nature. He was completely wrong, of course, yet there was every excuse for his mistake. For, as he himself tells us in effect, he found everywhere in that created nature which he knew so well, anomaly piled on anomaly and paradox on paradox, and he knew no more of theology than its simpler and more explicit statements." The sermons cover the following paradoxes: Peace and War Wealth and Poverty Sanctity and Sin Joy and Sorrow Love of God and Love of Man Faith and Reason Authority and Liberty Corporateness and Individualism Meekness and Violence The Seven Words Life and Death
