Books on the Sacraments have been appearing in great numbers recently. But it isn't often that a study of these mysteries of human unity is so clear and timely. In The People of God Father McCabe writes forcefully and with authority but with an awareness that intelligent people are reading him. He does not hedge; he is bold in his assertions. He sees in the Sacraments the means for formation of the real community which constitutes the Church. The Church he regards as the community which foreshadows the life for which God intended man. The Sacraments are envisioned here as the living contact with the humanity of Christ through which men share the divine life. It is unusual indeed to see explanations of these sources grace made so lucid and intellectually acceptable. The excitingly interested Catholic laity, anxious to know more of the fullness of life in the Church available to them in the Sacraments, will be pleased with this new addition to the books on this subject as will the priests who will find it updating their knowledge of these mysteries of salvation.
