Thomas Aquinas Summa Theologiae - God's Love For Other Things - Sadler's Lectures
This lecture discusses key ideas from the medieval Christian philosopher and theologian Thomas Aquinas' Summa Theologiae, 1st part, question 20, "God's Love", and examines his discussion in article 2, which examines the question whether God loves things other than God. Thomas considers four main lines of reasoning that would say that God either doesn't love other things or only loves some other things but not others. He then clarifies that God wills good to all things that exist, giving them the very being and goodness that they possess, so God loves all things insofar as they are. This doesn't mean that he loves all things to the same extent or in the same ways.
