Since the nature of a being’s activity is in keeping with its substance, the higher intellectual substances must understand in a more perfect way, inasmuch as they have intelligible species and powers that are more universal and are more unified. On the other hand, intellectual substances that are less perfect must be weaker in intelligence, and must have species that are more numerous and less universal.

All scripture is given by inspiration of God and is profitable for doctrine, reproof, correction, and instruction in righteousness (2 Timothy 3:16).
