Circumcision and the New Covenant
Early Christians usually said the true circumcision is of the heart, not just the flesh. Writers like Barnabas, Justin Martyr, Irenaeus, Tertullian, Clement, Origen, and Cyprian tied this to the new covenant and to Bible texts like Romans 2, Romans 4, and Colossians 2. They also said the old sign belonged to Israel as a sign, while faith and obedience mark God’s people now. The evidence is broad and early, though some passages are used in debate or in symbolic reading of Scripture.

What did early Christians believe about circumcision and the New Covenant?
Early Christian writers taught that physical circumcision was a sign for Israel, but the real mark of God’s people is the circumcision of the heart by faith and the Spirit. Barnabas, Justin Martyr, Irenaeus, Tertullian, Clement of Alexandria, Origen, Lactantius, and Cyprian all repeat this basic line in different ways. They often linked this to Abraham being counted righteous before circumcision, and to Bible passages like Romans 2, Romans 4, Galatians 6, and Colossians 2.
The witness is broad and early, though some writers use the theme as part of anti-Jewish debate or prophetic interpretation rather than a plain doctrine statement. Many more early Christian quotations, Bible passages, and source links are gathered below so you can study the evidence for yourself.

Questions Answered by the Sources
Did early Christians say circumcision was only a sign, not what makes someone righteous?
Several early Christian writers say circumcision was given as a sign or seal rather than as the basis of righteousness. They point to Abraham being counted righteous while still uncircumcised and treat the rite as a marker that points beyond itself.

Barnabas, The Epistle of Barnabas Direct teaching
...derness." Therefore He has circumcised our ears so that we might hear His word and believe, for the circumcision in which they trusted is abolished. For He declared that circumcision was not of the flesh, but they transgressed because an evil angel deluded them. He says to them, "These things says the Lord your God"—(here I find a new commandment)—"Sow not among thorns, but circumcise yourselves to the Lord." And why does He speak thus: "Circumcise the stubbornness of your heart, and harden not your neck?" And again: "Behold, says the Lord, all the nations are uncircumcised in the flesh, but this people are uncircumcised in heart." But you will say, "Yea, truly the people are circumcised for a seal." But so also is every Syrian and Arab, and all the priests of idols: are these then also within the bond of His covenant? Yes, the Egyptians also practice circumcision. Learn then, my children, about all things richly, that Abraham, the first who commanded circumcision, looking forward in spirit to Jesus, practiced that rite, having received the mysteries of the three letters. For [the Scripture] says, "And Abraham circumcised ten, and eight, and three hundred men of his household."

Archelaus, Disputation with Manes Direct teaching
...rt against his neighbor. For it is only the circumcision of the heart that brings salvation. Merely fleshly circumcision can be of no benefit to men unless they also have the spiritual circumcision. Listen also to what Scripture says about this: "Blessed are the pure in heart, for they shall see God." What need, then, is there for me to labor and suffer, since I have been told the short way of life, and know that it will be mine if only I can be pure in heart? And this fully agrees with the truth we have now learned: if a person succeeds in keeping the two commandments, he fulfills the whole law and the prophets. Moreover, Paul, the chief of the apostles, after all these sayings, gives us even clearer instruction on this subject when he says, "Or do you seek proof of Christ who speaks in me?" What then do I have to do with circumcision, seeing that I may be justified in uncircumcision? For it is written: "Is any man circumcised? Let him not become uncircumcised. Is any man uncircumcised? Let him not be circumcised. For neither of these is anything, but only the keeping of the commandments of God." Therefore, since circumcision is unable to save anyone, it is not greatly to be in

Justin Martyr, Dialogue with Trypho Direct teaching
...y from your souls, as God commands you to be washed in this laver, and be circumcised with the true circumcision. We would also follow the physical circumcision, the Sabbaths, and all the feasts, if we did not understand why they were commanded to you—specifically, because of your transgressions and the hardness of your hearts. If we patiently endure everything plotted against us by wicked people and demons, so that even amid unimaginable cruelties, death, and torments, we pray for mercy for those who inflict such things upon us, and do not wish to retaliate against anyone, just as the new Lawgiver commanded us, then how is it, Trypho, that we would not observe those rites that do not harm us—speaking of physical circumcision, Sabbaths, and feasts?

Clement of Alexandria, The Stromata (Miscellanies) Supporting witness
To illustrate: the noble apostle circumcised Timothy, though he loudly declared and wrote that circumcision made with hands profits nothing. But he did this so that he might not, by dragging those Hebrews who were reluctant listeners all at once away from the law to the circumcision of the heart through faith, compel them to break away from the synagogue. By accommodating himself to the Jews, he became a Jew, that he might gain all. He, then, who submits to accommodate himself merely for the benefit of his neighbors, for the salvation of those for whose sake he accommodates himself, not taking part in any dissimulation through the peril hanging over the just from those who envy them, such a one by no means acts under compulsion. But for the benefit of his neighbors alone, he will do things that he would not have done primarily, if he did not do them on their account. Such a one gives himself for the Church, for the disciples whom he has begotten in faith, as an example to those who are capable of receiving the supreme divine arrangement of the Instructor who loves man and loves God, for confirmation of the truth of his words, and for the exercise of love to the Lord. Such a one is

For which reason we think that no one is to be hindered from obtaining grace by that law which was already ordained, and that spiritual circumcision ought not to be hindered by carnal circumcision, but that absolutely every man is to be admitted to the grace of Christ, since Peter also in the Acts of the Apostles speaks, and says, The Lord has said to me that I should call no man common or unclean.

Justin Martyr, Dialogue with Trypho Supporting witness
...salvation shall go forth, and nations shall trust in My arm?' And by Jeremiah, concerning this same new covenant, He thus speaks: 'Behold, the days come, says the Lord, that I will make a new covenant with the house of Israel and with the house of Judah; not according to the covenant I made with their fathers on the day I took them by the hand to bring them out of the land of Egypt.' If, therefore, God proclaimed a new covenant that was to be established, and this for a light to the nations, we see and are convinced that people approach God, leaving their idols and other unrighteousness, through the name of Him who was crucified, Jesus Christ, and hold firm to their confession even unto death, and maintain piety. Moreover, by the works and by the accompanying miracles, it is possible for all to understand that He is the new law, and the new covenant, and the hope of those who from every people wait for the good things of God. For the true spiritual Israel, and descendants of Judah, Jacob, Isaac, and Abraham (who was approved of and blessed by God on account of his faith, and called the father of many nations, despite being uncircumcised), are we who have been led to God through

Lactantius, The Divine Institutes Direct teaching
In the same way, Isaiah also prophesied about the ending of circumcision. He says, “Thus says the Lord to the men of Judah who live at Jerusalem: Break up your unplowed ground, and do not sow among thorns. Circumcise yourselves to the Lord your God, and take away the foreskins of your heart, lest my fury come out like fire and burn in a way that no one can quench.” Moses himself also says in Deuteronomy 30:6, “In the last days the Lord will circumcise your heart, so that you may love the Lord your God.” Jesus the son of Nun, his successor, also said this: “And the Lord said to Jesus, Make very sharp flint knives, and sit and circumcise the children of Israel a second time.” He said that this second circumcision would not be of the flesh, as the first one was, which the Jews still practice even now, but of the heart and spirit. This was given by Christ, who was the true Jesus. For the prophet does not say, “And the Lord said to me,” but “to Jesus,” so that he might show that God was not speaking about him, but about Christ, to whom God was then speaking. For that Jesus was a figure of Christ. When he was first called Auses, Moses, foreseeing the future, ordered that he should be cal

Tertullian, Against Marcion Supporting witness
.... But why say more, when the Creator by the same prophet foretells the renovation more openly and clearly than the light itself? "Remember not the former things, neither consider the things of old." The old things have passed away, and new things are arising. "Behold, I will do new things, which shall now spring forth." Isaiah 43:18-19. So also by Jeremiah: "Break up for yourselves new pastures, and sow not among thorns, and circumcise yourselves in the foreskin of your heart." And in another passage: "Behold, the days come, says the Lord, that I will make a new covenant with the house of Jacob, and with the house of Judah; not according to the covenant that I made with their fathers in the day when I arrested their dispensation, in order to bring them out of the land of Egypt." He thus shows that the ancient covenant is only temporary, when He points to its change, and also when He promises that it will be followed by an eternal one. For by Isaiah He says: "Hear me, and you shall live; and I will make an everlasting covenant with you," adding, "the sure mercies of David," Isaiah 55:3, in order to show that that covenant was to run its course in Christ. That He was of the family

... moon is not visible, they do not keep the Sabbath, which is called the first; nor do they keep the new moon, nor the feast of unleavened bread, nor the feast, nor the great day." Then he gives the final answer to the question: "Do that also, learning in a holy and righteous way what we deliver to you. Keep these things, worshiping God in a new way, through Christ. For we find in the Scriptures, as the Lord says: 'Behold, I make with you a new covenant, not as I made with your fathers at Mount Horeb.' Jeremiah 31:31-32; Hebrews 8:8-10" He made a new covenant with us, for what belonged to the Greeks and Jews is old. But we, who worship Him in a new way, in the third form, are Christians. For clearly, I think, he showed that the one and only God was known by the Greeks in a Gentile way, by the Jews in a Jewish way, and by us in a new and spiritual way.
