How does he explain Creation?
I've tried to be in accord with Aquinas' view where it can be applied - avoiding the necessity of the name "God" when possible. The Summa Theologica is more an explanation of God, but creation is mentioned over a hundred times. Another section that might have just a bit relevance in our context:
Since therefore God is outside the whole order of creation, and all creatures are ordered to Him, and not conversely, it is manifest that creatures are really related to God Himself; whereas in God there is no real relation to creatures, but a relation only in idea, inasmuch as creatures are referred to Him. Thus there is nothing to prevent these names which import relation to the creature from being predicated of God temporally, not by reason of any change in Him, but by reason of the change of the creature; as a column is on the right of an animal, without change in itself, but by change in the animal.
