Sheed offers an intense, cohesive, accessible, and altogether spectacular narrative summary of Catholic theology, for him the sole medium for understanding the reality of man, man's relationship with the Infinite, and the Infinite's role in the finite universe. His goal is to guide man toward sanity -- toward an understanding of Reality, and toward an ability to engage that Reality; he finds this sanity within Catholicism: "This Church, more rigid than any in dogma and law, is, as no other Church ever has been, the home of every type of human being, of every nation and of every sort of peson within every nation. Because only in the Church is man fully himself." Covered are: human and salvation histories, the nature of man, opposing philosophies, dogma, suffering, grace, eschatology, and more. I most appreciated his ability to engage the question of God on multiple levels: natural evidence, Catholicism's historicity, Scripture, pop psychology and science, specific teachings and practices, etc. Contained within is one of the clearest definitions of the Trinity I've ever read, along with compelling answers to major questions posed to the Church (infallibility, sacramental life, etc.).
