Exhaustive and explicit, Aquinas’ Summa Contra Gentiles - Book 1, is a brilliant synthesis of faith and reason which has decisively and permanently impacted philosophy and religion since the 13th century. Proving that God exists, Aquinas writing from an apologetic viewpoint denies the claims of the Islam of his day. All three sections, including 38 tracts, 631 questions, about 3000 articles, 10,000 objections and their answers, reveal God’s nature, His immutability, infinite, eternal character, and specifically His knowledge of future contingencies. God’s will, essence and the problem of evil are also discussed. Excellent!
