2016 Reprint of 1954 Edition. Full facsimile of the original edition, not reproduced with Optical Recognition Software. This selection from Aquinas' magnum opus, the "Summa Theologica" covers the great Catholic philosopher's words on the nature of God, the nature of sin, and how God's grace sanctifies and transforms the lives of Christians. Concerning the nature of God, this selection includes Aquinas' arguments for God's existence, his description of God's metaphysical attributes, and his exploration of how God interacts with creation and the people who inhabit it. In the portion of the selection focusing on sin, Aquinas asks and answers the questions of what sin is and how it affects human beings. The selection's last portion presents Aquinas' thoughts on sin's remedy, God's grace. For those seeking Aquinas' insight on the topics here presented, this selection may prove a less cumbersome and more streamlined alternative to the entire Summa.
