This is the first book of a two-volume series entitled God and the Human Condition; the second volume, God And the Human Race, will be published in 1967. The present work explores the bases of man's knowledge of God. An introductory section discusses such knowledge in general and the concept of divine revelation. The following chapters treat, in adequate detail, such aspects of the human knowledge of God as the relationship of theology to revelation, divine inspiration of Sacred Scripture, Scripture and the teaching authority of the Church, knowledge of God through mystical experience, God as known in the Old and New Testament, philosophical knowledge of God, knowledge of God through Christ, and knowledge of God as triune. It should be sufficient to observe that God and the Human Mind is the equal, in every way, of Mr. Sheed's now classic Theology and Sanity; it has the same lucidity, the same mastery of its subject, and the same delightfully irrepressible good humor reminiscent of Chesterton at his best. It is impossible to read God and the Human Mind without being painlessly instructed and enormously entertained, and the book should, on the basis of its own quality and of Mr. Sheed's reputation, find a vast audience among Catholics at all levels.
