Ambrose of Milan : Therefore, the Lord permitted mortality to steal in [as an atonement], that guilt might cease. But so that the end set by nature might not also be in death, there was granted a resurrection from the dead, that the guilt might fail through death but the nature be continued through resurrection. And so death is a passage for all men, but you must pass with virtuous steadfastness—a passage from corruption to incorruption, from mortality to immortality, from disquiet to tranquillity…. What indeed is this death but the burial of vices and the awakening of virtues? For this reason "may my soul depart among the souls of the righteous," that is, "may it be buried together with them," that it may lay down its sins and take up the grace of the just, who "bear about the dying of Christ in their body" and soul. Ambrose of Milan : This, too, is plain, that in him who is baptized the Son of God is crucified, for our flesh could not do away sin unless it were crucified in Jesus Christ. And then it is written that: "All we who were baptized into Jesus Christ were baptized into His death." And farther on: "If we have been planted in the likeness of His death, we shall be also in the likeness of His resurrection, knowing that our old man was fastened with Him to His cross." And to the Colossians he says: "Buried with Him by baptism, wherein ye also rose again with Him." Which was written to the intent that we should believe that He is crucified in us, that our sins may be purged through Him, that He, Who alone can forgive sins, may nail to His cross the handwriting which was against us. — Concerning Repentance, Book 2 Ambrosiaster : He says that the Gentiles were dead: first, because they did not want to accept the law that was given as a testimony by the Creator and to condemn vices; then, because they were unworthy of life due to the impiety of their sins; therefore, he separated them from the Jews as if they were enemies of the one true God. But the Jews, living in the confession of one God, when Christ came, learned the mystery of God, which they had been expecting for their justification: that in Him, what had been taken away from them, because it is impossible to be without sin, they might receive forgiveness. — Commentary on Colossians Augustine of Hippo : For if these passing days gladden us so much, during which we devoutly commemorate the passion and resurrection of Christ, how will the eternal one bless us, where we shall see Him and remain with Him, whom we now rejoice in, longing and hoping for? How great an exultation will He give to His Church, to which, regenerated through Christ, He removes in a way the foreskin of carnal nature, that is, the reproach of birth? Hence it is said: And you, when you were dead in your sins and in the uncircumcision of your flesh, He has made alive with Him, forgiving us all our debts. For as in Adam all die, so also in Christ shall all be made alive. Thus, what was hidden in the shadow of the old circumcision is revealed in the baptism of Christ; and this also pertains to that same uncircumcision made without hands, when the covering of carnal ignorance is removed. When you shall have passed on to Christ, he says, the veil is taken away. — Sermon 229D Clement of Alexandria : To attain the knowledge of God is impossible for those who are still under the control of their passions. Therefore they cannot attain the salvation they hope for as they have not obtained any knowledge of God. He who fails to attain this end is clearly subject to the charge of being ignorant of God, and ignorance of God is shown by a man's manner of life. It is absolutely impossible at the same time to be a man of understanding and not to be ashamed to gratify the body. Nor can the view that pleasure is the supreme Good be reconciled with the view that only the beautiful is good, or that only the Lord is beautiful, and God alone is good and is alone to be loved. "You are circumcised in Christ with a circumcision not done with hands, which consists rather in the putting away of the carnal body, in the circumcision of Christ." "If you then are risen with Christ, seek those things which are above; have in mind higher things, not earthly things. For you are dead, and your life is hid with Christ in God" -- but not the fornication which they practice. "Mortify therefore your earthly members, fornication, uncleanness, passion, lust; for on account of these wrath is coming." Let them also therefore "put away anger, wrath, wickedness, blasphemy, filthy talk from their mouth, putting off the old man with its lusts, and putting on the new man which is renewed to possess full knowledge according to the image of him who created it." — The Stromata Book 3 Cyprian : That the first circumcision of the flesh is made void, and the second circumcision of the spirit is promised instead. In Jeremiah: "Thus saith the Lord to the men of Judah, and to them who inhabit Jerusalem, Renew newness among you, and do not sow among thorns: circumcise yourselves to your God, and circumcise the foreskin of your heart; lest my anger go forth like fire, and burn you up, and there be none to extinguish it." Also Moses says: "In the last days God will circumcise thy heart, and the heart of thy seed, to love the Lord thy God." Also in Jesus the son of Nave: "And the Lord said unto Jesus, Make thee small knives of stone, very sharp, and set about to circumcise the children of Israel for the second time." Paul also, to the Colossians: "Ye are circumcised with the circumcision not made with hands in the putting off of the flesh, but with the circumcision of Christ." Also, because Adam was first made by God uncircumcised, and righteous Abel, and Enoch, who pleased God and was translated; and Noah, who, when the world and men were perishing on account of transgressions, was chosen alone, that in him the human race might be preserved; and Melchizedek, the priest according to whose order Christ was promised. Then, because that sign did not avail women, but all are sealed by the sign of the Lord. — Treatise XII Three Books of Testimonies Against the Jews Hippolytus of Rome : He washed in Jordan, and when He was baptized He received a figure and a seal in the water of (another spiritual booty beside) the body born of the Virgin. (And the object of this was,) when the Archon condemned his own peculiar figment (of flesh) to death, (that is,) to the cross, that that soul which had been nourished in the body (born of the Virgin) might strip off that body and nail it to the (accursed) tree. (In this way the soul) would triumph by means of this (body) over principalities and powers, and would not be found naked, but would, instead of that flesh, assume the (other) body, which had been represented in the water when he was being baptized. — Hippolytus Refutation of All Heresies Book VIII Irenaeus : Moreover, we learn from the Scripture itself, that God gave circumcision, not as the completer of righteousness, but as a sign, that the race of Abraham might continue recognisable. For it declares: "God said unto Abraham, Every male among you shall be circumcised; and ye shall circumcise the flesh of your foreskins, as a token of the covenant between Me and you." This same does Ezekiel the prophet say with regard to the Sabbaths: "Also I gave them My Sabbaths, to be a sign between Me and them, that they might know that I am the Lord, that sanctify them." And in Exodus, God says to Moses: "And ye shall observe My Sabbaths; for it shall be a sign between Me and you for your generations." These things, then, were given for a sign; but the signs were not unsymbolical, that is, neither unmeaning nor to no purpose, inasmuch as they were given by a wise Artist; but the circumcision after the flesh typified that after the Spirit. For "we," says the apostle, "have been circumcised with the circumcision made without hands." And the prophet declares, "Circumcise the hardness of your heart." — Against Heresies Book IV John Chrysostom : See how near he is come to the thing. He saith, "In the putting" quite away, not putting off merely. "The body of sins." He means, "the old life." He is continually adverting to this in different ways, as he said above, "Who delivered us out of the power of darkness, and reconciled us who were alienated," that we should be "holy and without blemish." (Col. i. 13, 21.) No longer, he saith, is the circumcision with the knife, but in Christ Himself; for no hand imparts this circumcision, as is the case there, but the Spirit. It circumciseth not a part, but the whole man. It is the body both in the one and the other case, but in the one it is carnally, in the other it is spiritually circumcised; but not as the Jews, for ye have not put off flesh, but sins. When and where? In Baptism. And what he calls circumcision, he again calls burial. Observe how he again passes on to the subject of righteous doings; "of the sins," he saith, "of the flesh," the things they had done in the flesh. He speaks of a greater thing than circumcision, for they did not merely cast away that of which they were circumcised, but they destroyed it, they annihilated it. — Homily on Colossians 6 Severian of Gabala : Through baptism comes the stripping away and circumcision of sins…. Those being baptized in the blood of Christ confess that they share in his death through baptism and that following this they enjoy the resurrection. Resurrection is used here in a twofold sense, the one spiritual and the other physical. All persons will rise through the resurrection of Christ from the dead. Those, however, who have not been baptized in Christ but have died without faith will share in the general resurrection. However, they will not enjoy the promise of redemption…. As many as were baptized into Christ, these have freely benefitted before the general resurrection from the spiritual resurrection, for they have already risen from the death of sins. Thus, Paul also says: "in whom you were raised," not "in whom you will be raised." . Tertullian : Thus, that which becomes a spoil when stripped off, was a vestment as long as it remained laid over. Hence the apostle, when he call circumcision "a putting off (or spoliation) of the flesh," affirmed the skin to be a coat or tunic. — On the Resurrection of the Flesh Tertullian : And so to the Law presently had to succeed the Word of God introducing the spiritual circumcision. Therefore, by means of the wide licence of those days, materials for subsequent emendations were furnished beforehand, of which materials the Lord by His Gospel, and then the apostle in the last days of the (Jewish) age, either cut off the redundancies or regulated the disorders. — To His Wife Book I
