1. Thus then does the Lord plainly show that it was the true Lord and the one God who had been set forth by the law; for Him whom the law proclaimed as God, the same did Christ point out as the Father, whom also it behoves the disciples of Christ alone to serve. By means of the statements of the law, He put our adversary to utter confusion; and the law directs us to praise God the Creator (Demiurgum), and to serve Him alone. Since this is the case, we must not seek for another Father besides Him, or above Him, since there is one God who justifies the circumcision by faith, and the uncircumcision through faith. For if there were any other perfect Father above Him, He (Christ) would by no means have overthrown Satan by means of His words and commandments. For one, ignorance cannot be done away with by means of another ignorance, any more than one defect by another defect. If, therefore, the law is due to ignorance and defect, how could the statements contained therein bring to nought the ignorance of the devil, and conquer the strong man? For a strong man can be conquered neither by an inferior nor by an equal, but by one possessed of greater power. But the Word of God is the superior above all. He who is loudly proclaimed in the law: "Hear, O Israel, the Lord thy God is one God;" and, "Thou shalt love the Lord thy God with all thy heart;" and, "Him shalt thou adore, and Him alone shalt thou serve." Then in the Gospel, casting down the apostasy by means of these expressions. He did both overcome the strong man by His Father's voice, and He acknowledges the commandment of the law to express His own sentiments, when He says, "Thou shalt not tempt the Lord thy God." For He did not confound the adversary by the saying of any other, but by that belonging to His own Father, and thus overcame the strong man.
