Ambrosiaster : Now he speaks to those who, because they still served the pleasures of the world, were carnal. Although they were already baptized and had received the Holy Spirit, yet because after baptism they immediately returned to the old man, whom they had renounced, they are called carnal. For the Holy Spirit remains in the one in whom he has poured himself, if he remains in the purpose of regeneration: if not, he departs; but in such a way that if a man reforms himself, he returns to him. Always ready for good, diligent in repentance. — Commentary on 1 Corinthians Augustine of Hippo : Paul was not speaking of their bodies but of their carnal spirits. — City of God 22.21 Clement of Alexandria : So also may we take the Scripture: "And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ;" so that the carnal may be understood as those recently instructed, and still babes in Christ. For he called those who had already believed on the Holy Spirit spiritual, and those newly instructed and not yet purified carnal; whom with justice he calls still carnal, as minding equally with the heathen the things of the flesh: "For whereas there is among you envy and strife, are ye not carnal, and walk as men?" — The Instructor Book 1 Cyprian : Thus also the Apostle Paul, when he was urging the merits of peace and charity, and when he was strongly asserting and teaching that neither faith nor alms, nor even the passion itself of the confessor and the martyr, would avail him, unless he kept the requirements of charity entire and inviolate, added, and said: "Charity, is magnanimous, charity is kind, charity envieth not; " teaching, doubtless, and showing that whoever is magnanimous, and kind, and averse from jealousy and rancour, such a one can maintain charity. Moreover, in another place, when he was advising that the man who has already become filled with the Holy Spirit, and a son of God by heavenly birth, should observe nothing but spiritual and divine things, he lays it down, and says: "And I indeed, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ. I have fed you with milk, not with meat: for ye were not able hitherto; moreover, neither now are ye able. For ye are yet carnal: for whereas there are still among you jealousy, and contention, and strifes, are ye not carnal, and walk as men? " — Treatise X On Jealousy and Envy Cyprian : That charity and brotherly affection are to be religiously and stedfastly practised. In Malachi: "Hath not one God created us? Is there not one Father of us all? Why have ye certainly deserted every one his brother? " Of this same thing according to John: "Peace I leave with you, my peace I give unto you." Also in the same place: "This is my commandment, That ye love one another, even as I have loved you. Greater love than this has no man, than that one should lay down his life for his friends." Also in the same place: "Blessed are the peacemakers, for they shall be called the sons of God." Also in the same place: "Verily I say unto you, That if two of you shall agree on earth concerning everything, whatever you shall ask it shall be given you from my Father which is in heaven. For wherever two or three are gathered together in my name, I am with them." Of this same thing in the first Epistle to the Corinthians: "And I indeed, brethren, could not speak unto you as to spiritual, but as to carnal, as to babes in Christ. I have given you milk for drink, not meat: for while ye were yet little ye were not able to bear it, neither now are ye able. For ye are still carnal: for where there are in you emulation, and strife, and dissensions, are ye not carnal, and walk after man? " — Treatise XII. Three Books of Testimonies Against the Jews. Irenaeus : Those persons, then, who possess the earnest of the Spirit, and who are not enslaved by the lusts of the flesh, but are subject to the Spirit, and who in all things walk according to the light of reason, does the apostle properly term "spiritual," because the Spirit of God dwells in them. Now, spiritual men shall not be incorporeal spirits; but our substance, that is, the union of flesh and spirit, receiving the Spirit of God, makes up the spiritual man. But those who do indeed reject the Spirit's counsel, and are the slaves of fleshly lusts, and lead lives contrary to reason, and who, without restraint, plunge headlong into their own desires, having no longing after the Divine Spirit, do live after the manner of swine and of dogs; these men, [I say], does the apostle very properly term "carnal," because they have no thought of anything else except carnal things. For the same reason, too, do the prophets compare them to irrational animals, on account of the irrationality of their conduct, saying, "They have become as horses raging for the females; each one of them neighing after his neighbour's wife." And again, "Man, when he was in honour, was made like unto cattle." This denotes that, for his own fault, he is likened to cattle, by rivalling their irrational life. And we also, as the custom is, do designate men of this stamp as cattle and irrational beasts. ...For men of this stamp do indeed say that they believe in the Father and the Son, but they never meditate as they should upon the things of God, neither are they adorned with works of righteousness; but, as I have already observed, they have adopted the lives of swine and of dogs, giving themselves over to filthiness, to gluttony, and recklessness of all sorts. Justly, therefore, did the apostle call all such "carnal" and "animal,"—[all those, namely], who through their own unbelief and luxury do not receive the Divine Spirit, and in their various phases cast out from themselves the life-giving Word, and walk stupidly after their own lusts: the prophets, too, spake of them as beasts of burden and wild beasts; custom likewise has viewed them in the light of cattle and irrational creatures; and the law has pronounced them unclean. — Against Heresies (Book V, Chapter 8) John Chrysostom : "And I, brethren, could not speak unto you as unto spiritual." Why, in the first place, says he, though you had been perfect in spiritual things also, not even so ought you to be elated; for what you preach is not your own, nor such as yourselves have found from your own means. But now even these things ye know not as ye ought to know them, but ye are learners, and the last of all. Whether therefore the Gentile wisdom be the occasion of your high imaginations; that hath been proved to be nothing, nay, in regard to spiritual things to be even contrary unto us: or if it be on account of things spiritual, in these, too, ye come short and have your place among the hindmost. Wherefore he saith, "I could not speak unto you as unto spiritual." He said not, "I did not speak," lest the thing might seem to proceed from his grudging them somewhat; but in two ways he brings down their high spirit; first, because they knew not the things that are perfect; next, because their ignorance was owing to themselves: yea, in a third way besides these, by pointing out that "not even now are they able [to bear it]." For as to their want of ability at first, that perhaps arose from the nature of the case. In fact, however, he does not leave them even this excuse. For not through any inability on their part to receive high doctrines, doth he say they received them not, but because they were "carnal." However, in the beginning this was not so blame-worthy; but that after so long a time, they had not yet arrived at the more perfect knowledge, this was a symptom of most utter dulness. It may be observed, that he brings the same charge against the Hebrews, not however, with so much vehemence. For those, he saith, are such, partly because of tribulation: but these, because of some appetite for wickedness. Now the two things are not the same. He implies too, that in the one case he was intending rebuke, in the other rather stirring them up, when he spake these words of truth. For to these Corinthians he saith, "Neither yet now are ye able;" but unto the others "Wherefore let us cease to speak of the first principles of Christ, and press on unto perfection:" and again, "we are persuaded better things concerning you, and things which accompany salvation, though we thus speak." — Homily on 1 Corinthians 8 Tertullian : That they likewise (remember), what was written to the Corinthians, that they "were yet carnal," who "required to be fed with milk," being as yet "unable to bear strong meat; " who also "thought that they knew somewhat, whereas they knew not yet anything, as they ought to know. — The Prescription Against Heretics
