The Church Fathers on this verse

4 Church Fathers comment on this verse

John Chrysostom

4th centuryChurch Father

However, the misguided and foolish Jews, remaining in darkness despite the arrival of the truth, continue to linger beside the lamp while the radiance of truth has fully illuminated the world. They cling to spiritual milk when it is already time for solid nourishment. These individuals refuse to heed the blessed Apostle Paul, who proclaims: “And he received the sign of circumcision as a seal of righteousness through faith, which he had in uncircumcision” (Rom. 4:11). Observe how the apostle instructs us that Abraham received circumcision as a sign, while not yet being circumcised, he displayed righteousness through faith.

This is so a Jew cannot claim, "Did not Abraham become justified through circumcision?" For this reason, the blessed apostle, who was educated under Gamaliel and meticulously learned the law, cautions, “Do not think, shameless Jews, that circumcision by itself justified him; it was his faith that justified him before he was circumcised: ‘Abram believed the Lord, and He counted it to him as righteousness’” (Gen. 15:6). Thus, having already been justified by faith in God, Abraham received the sign of circumcision afterward; God first altered the letter of his name and then commanded circumcision, demonstrating that He selects and draws near to a righteous man solely due to their great virtue, along with their descendants. Just as individuals who purchase slaves often change their names and attire to set them apart and reveal ownership, so the God of all humanity, wishing to distinguish Abraham from others, added a letter to indicate he would be the father of many nations and instituted circumcision for his people, setting them apart from all other nations.

Yet, if in their blindness they still cling to the fleshly circumcision, disregarding Paul’s words, “If ye be circumcised, it profiteth you nothing for Christ” (Gal. 5:2), the Lord came to abolish such practices and fulfilled the law entirely to put an end to future observances of the law. This prompted blessed Paul to declare, “You who justify yourselves by the law... have fallen from grace” (Gal. 5:4). Therefore, we shall heed the blessed Paul and embrace the uncircumcision of the flesh. He informs us, “In Him you are,” meaning, “and are circumcised by the circumcision of the uncircumcised, by the removal of the sinful body of the flesh, by the circumcision of Christ.” Moreover, to clarify what this circumcision entails, he adds: “Having been buried with Him in baptism” (Col. 2:11, 12). Just as their sign of circumcision distinguished them as God’s chosen people, the baptismal circumcision serves as a clear distinction between the faithful and the unfaithful among us. “In Him ye are,” states the apostle, “and are circumcised by the circumcision of the uncircumcision, by the removal of the sinful body of the flesh.” While circumcision involves putting away the flesh, baptism embodies the removal of sins. Therefore, having shed the sinful flesh and donned a clean garment, let us, dear friends, pursue holiness; overcoming fleshly desires, let us strive for virtue. Guided by grace, let us live like him who existed under the law, or even prior to the law itself, so that by following his example, we may be deemed worthy of entering into his embrace and receiving eternal blessings, through the grace and mercy of our Lord Jesus Christ, to whom be glory, power, and honor, along with the Father and the Holy Spirit, now and forever, and unto the ages of ages. Amen.

Cyrill of Alexandria

5th centuryChurch Father

The covenant of God pertains to the physical form of the one who does not act according to human inclinations, as stated in 2 Corinthians 10:3, and continually bears the mortality of Jesus within the flesh, as indicated in 2 Corinthians 4:10.

Dimitri of Rostov

17th centuryChurch Father

God established the law of circumcision for Abraham, his household, and all his descendants, serving as a foreshadowing of Christian baptism, as well as a representation of repentance, the mortification of sinful desires, and the severing of all wicked actions. Moreover, circumcision symbolizes the resurrection. Just as God commanded that newborn males be circumcised on the eighth day, so shall all humanity emerge from their graves on the day of the final resurrection, as if they were being born anew, ‘will be renewed like an eagle's youth’ (Psalm 102:5). Following the seven ages of the world, this moment will herald the eighth age, characterized by eternal life, where all forms of natural decay in human flesh will be utterly banished. As the Apostle declares, “it is fitting that this corruptible be clothed with incorruption, and this mortal be clothed with immortality” (1 Cor. 15:53).

Philaret of Moscow (Drosdow)

19th centuryChurch Father

Born in a household or purchased, the circumcision of servants and foreigners is mandated, likely because those uncircumcised within the home of the circumcised could pose a discomfort or temptation to the children of the covenant. Additionally, this practice may symbolize a transformative truth: that in God's promises to Abraham lies the salvation of all peoples, tribes, and nations. The question arises: can a master circumcise a servant without their consent? Maimonides suggests that the servant must either willingly accept circumcision or, if they do not consent, be sold to a different master.

"My covenant upon your body shall be an everlasting covenant." The term 'everlasting' is used here similarly to how the law is sometimes described as everlasting, indicating it is dependent on the authority of the lawgiver and the fulfillment of lawful conditions.
