Theology is also commended by its author — God, not Aristotle or Euclid

But as much as this science is commended from its object, so much also does its author commend it. For the remaining sciences glory in some illustrious man as their chief author. Aristotle is held the prince of the philosophers, and Hippocrates of the physicians; and the mathematical disciplines acknowledge Euclid as their parent. But theology claims God for itself as author, from whom this sacred teaching has flowed forth. For prophecy was not brought in of old by the will of man, as the Apostle Peter says (2 Peter 1:21); but holy men of God spoke as they were moved by the Holy Spirit, who first consigned it in writing.

Not without the deity, indeed, were the good arts and disciplines invented; and the light of reason itself descends from the Father of lights (James 1:17), who is the mover and governor of nature. But the principles on which theology rests are the express sayings and oracles of God, by which those things are made manifest which could not have become known except by a light higher than reason.
