37 Unless perchance the frenzy of utter desperation will venture to rush to such lengths that, inasmuch as the Apostle has called Christ Lord, no one ought to acknowledge Him as anything else save Lord, and that because He has the property of Lord He has not the true Godhead. But Paul knows full well that Christ is God, for he says, Whose are the fathers, and of whom is Christ, Who is God over all. It is no creature here who is reckoned as God; nay, it is the God of things created Who is God over all.
