Jerome : (v. 15) For neither circumcision is anything, nor uncircumcision, but a new creature. As faithful and unfaithful, when there is one in substance, are divided into two according to the diversity of understanding, the Apostle saying: Stripping yourselves of the old man with his works, and putting on the new, who is renewed unto knowledge according to the image of the Creator (Colossians 3:9-10): in the same way, the world, although it is one in substance, is made different according to the understanding. Sinners, the old world is: holy, new. For when the world has been crucified with the holy, neither circumcision nor uncircumcision is to it: not Jew, nor Gentile: but a new creature, into which the body of our humility is transformed, conformed to the body of the glory of Christ: For the old things have passed away, behold all things have become new (II Cor. V). And as the glory of the sun is different from the glory of the moon, and the glory of the stars: for star differs from star in glory: so also is the resurrection of the dead (I Cor. XV, 41, 42). About this, Daniel agrees with the same voice, saying: Many of those who sleep in the dust of the earth shall awake: some to everlasting life, and some to shame and everlasting contempt (Dan. XII, 2); and: Those who are wise shall shine like the brightness of the sky. And concerning the righteous: Many shall be like the stars forever. For neither circumcision counts for anything, nor uncircumcision, but a new creation without these parts of the body, which can be cut. So we also who love God, and the things that are prepared for us, which eye hath not seen, nor ear heard, neither hath it entered into the heart of man, what things God hath prepared for them that love him (1 Corinthians 2), when we shall be transformed in the body of the humility of Christ, into the body of the glory of the Lord Jesus Christ, shall have that kind of body that neither a Jew can oppose nor a Gentile preserve with circumcision. Not that it is anything else in substance, but that it is different in glory. For it is necessary for this mortal to put on immortality, and for this corruptible body to be clothed with incorruption (I Cor. XV, 53). This is similar to what the blessed evangelist John said: Beloved, we are now children of God, and it has not yet been revealed what we shall be. We know that when it is revealed, we shall be like Him, for we shall see Him as He is (I John III, 2). Therefore, since that body of the glory of Jesus Christ, which had the marks of the nails after the resurrection and entered through closed doors, has not yet been revealed, let us who have already been raised up with Christ in baptism, as new-born men, not serve circumcision or uncircumcision, but believe that we are already what we shall be in the future. — Commentary on Galatians John Chrysostom : "For neither is circumcision any thing, nor uncircumcision, but a new creature. And as many as shall walk by this rule, peace be upon them, and mercy, and upon the Israel of God." Observe the power of the Cross, to what a pitch it hath raised him! not only hath it put to death for him all mundane affairs, but hath set him far above the Old Dispensation. What can be comparable to this power? for the Cross hath persuaded him, who was willing to be slain and to slay others for the sake of circumcision, to leave it on a level with uncircumcision, and to seek for things strange and marvellous and above the heavens. This our rule of life he calls "a new creature," both on account of what is past, and of what is to come; of what is past, because our soul, which had grown old with the oldness of sin, hath been all at once renewed by baptism, as if it had been created again. Wherefore we require a new and heavenly rule of life. And of things to come, because both the heaven and the earth, and all the creation, shall with our bodies be translated into incorruption. Tell me not then, he says, of circumcision, which now availeth nothing; (for how shall it appear, when all things have undergone such a change?) but seek the new things of grace. For they who pursue these things shall enjoy peace and amity, and may properly be called by the name of "Israel." While they who hold contrary sentiments, although they be descended from him (Israel) and bear his appellation, have yet fallen away from all these things, both the relationship and the name itself. But it is in their power to be true Israelites, who keep this rule, who desist from the old ways, and follow after grace. — Homily on Galatians 6 Oecumenius : — [OECUMENIUS] "but a new creation." A new creation, he says, of all things; for all who were circumcised and those uncircumcised alike, having believed, have become a new creation, having buried the old man, and we having been regenerated by the washing of baptism. [end of the excerpt by Oecumenius] — — Commentary on Galatians Theodoret of Cyrus : Paul also mentions a new creation in his letter to the Corinthians. … The strict meaning of new creation is the transformation of all things which will occur after the resurrection from the dead. For then the creation will be freed from sin's burden and redeemed. Paul demonstrates that saving baptism is an image of things to come. In it we put off the old nature and put on the new. And we, ridding ourselves of sin's burden, receive the grace of the Spirit. Yet neither the most holy baptism nor the life to come recognizes any difference between circumcision and uncircumcision. By world he means the affairs of life—honor, glory and wealth. To these he declares himself dead. — EPISTLE TO THE Galatians 6.15
