Homily of Chrysostom on Galatians iv
ALMIGHTY God, who hast given us thy only-begotten Son to take our nature upon him, and as at this time to be born of a pure virgin; Grant that we being regenerate, and made thy children by adoption and grace, may daily be renewed by thy Holy Spirit; through the same our Lord Jesus Christ, who liveth and reigneth with thee and the same Spirit ever, one God, world without end. Amen.
Here he states two objects and effects of the Incarnation, deliverance from evil and supply of good, things which none could compass but Christ. They are these; deliverance from the curse of the Law, and promotion to sonship. Fitly does he say, that we might "receive," "[be paid,]" implying that it was due; for the promise was of old time made for these objects to Abraham, as the Apostle has himself shown at great length. And how does it appear that we have become sons? he has told us one mode, in that we have put on Christ who is the Son; and now he mentions another, in that we have received the Spirit of adoption.
"Let us therefore follow after the things which make for peace, and things wherewith one may edify another" [St. Paul's Epistle to the Romans 14:19]
