For as many of you as have been baptized into Christ have put on Christ.
All Commentaries on Galatians 3:27 Go To Galatians 3
John Chrysostom
AD 407
Why does he not say, For as many of you as have been baptized into Christ, have been born of God? for this was what directly went to prove that they were sons—because he states it in a much more awful point of view; If Christ be the Son of God, and you have put on Him, thou who hast the Son within you, and art fashioned after His pattern, hast been brought into one kindred and nature with Him.
