101. And rightly did the Lord speak of His own Father, but of the Lord of heaven and earth; so that thou, when thou readest of the Father and the Lord, mayest understand it is the Father of the Son, and the Lord of Creation. In the one title rests the claim of nature, in the other the authority to rule. For taking on Himself the form of a servant, He calls Him Lord, because He has submitted to service; being equal to Him in the form of God, but being a servant in the form of His body: for service is the due of the flesh, but lordship is the due of the Godhead. Wherefore also the Apostle says: “The God of our Lord Jesus Christ, the Father of glory,” 2 Cor. i. 3. that is, terming Him God of the adoption of humanity but the Father of glory. Did God have two Sons, Christ and Glory? Certainly not. Therefore if there is one Son of God, even Christ, Christ is Glory. Why dost thou strive to belittle Him who is the glory of the Father?
