44. What of justice that pertains to God? As the Lord says, "Ye cannot serve two masters," and the apostle denounces those who serve the creature rather than the Creator, was it not said before in the Old Testament, "Thou shalt worship the Lord thy God, and Him only shalt thou serve?" I need say no more on this, for these books are full of such passages. The lover, then, whom we are describing, will get from justice this rule of life, that he must with perfect readiness serve the God whom he loves, the highest good, the highest wisdom, the highest peace; and as regards all other things, must either rule them as subject to himself, or treat them with a view to their subjection. This rule of life, is, as we have shown, confirmed by the authority of both Testaments.
