By Dr. Jeff Mirus, Catholic Culture - The book is divided into five sections: God and Man; Christ and His Church; Sin; Sacraments; and World, Soul, and Things. The last section requires some explanation. It engages in a brief survey of the nature of the commandments and explores the four Last Things, but it also covers the mystery of sex, the evil of birth prevention, and marriage problems. The book closes with lessons on the feminine principle in religion, prayer, and “world, soul and things”—which essentially explores the nature of true human fulfillment.
