Two years before he died, St. Thomas Aquinas -- probably the greatest teacher the Church has ever known -- was asked by his assistant, Brother Reginald, to write a simple summary of the Faith of the Catholic Church for those who lacked the time or the stamina to tackle his massive Summa Theologica.In response, the saint quickly set down -- in language that non-scholars can understand -- his insights into the major topics of theology: the Trinity, Providence, the Incarnation, the Last Judgment, and much more. Here, then, is not only St. Thomas's concise statement of the key elements of his thought, but a handy reference source for the essential truths of the Catholic Faith.
