Clement of Alexandria : "For God hath revealed it to us by the Spirit. For the Spirit searcheth all things, even the deep things of God." For he recognises the spiritual man and the Gnostic as the disciple of the Holy Spirit dispensed by God, which is the mind of Christ. "But the natural man receiveth not the things of the Spirit, for they are foolishness to him." Now the apostle, in contradistinction to gnostic perfection, calls the common faith the foundation, and sometimes milk... — The Stromata Book 5 Irenaeus : True knowledge, then, consists in the understanding of Christ, which Paul terms the wisdom of God hidden in a mystery, which "the natural man receiveth not," the doctrine of the cross; of which if any man "taste," he will not accede to the disputations and quibbles of proud and puffed-up men, who go into matters of which they have no perception. For the truth is unsophisticated; and "the word is nigh thee, in thy mouth and in thy heart," as the same apostle declares, being easy of comprehension to those who are obedient. For it renders us like to Christ, if we experience "the power of his resurrection and the fellowship of His sufferings." For this is the affinity of the apostolical teaching and the most holy "faith delivered unto us," which the unlearned receive, and those of slender knowledge have taught, not "giving heed to endless genealogies," but studying rather [to observe] a straightforward course of life; lest, having been deprived of the Divine Spirit, they fail to attain to the kingdom of heaven. For truly the first thing is to deny one's self and to follow Christ; and those who do this are borne onward to perfection, having fulfilled all their Teacher's will, becoming sons of God by spiritual regeneration, and heirs of the kingdom of heaven; those who seek which first shall not be forsaken. — Fragments from the Lost Writings of Irenaeus, #36 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. — Against Heresies (Book V, Chapter 8) John Chrysostom : "The natural man receiveth not the things of the Spirit." For as with these eyes no man could learn the things in the heavens; so neither the soul unaided the things of the Spirit. And why speak I of the things in heaven? It receives not even those in earth, all of them. For beholding afar off a square tower, we think it to be round; but such an opinion is mere deception of the eyes: so also we may be sure, when a man by means of his understanding alone examines the things which are afar off much ridicule will ensue. For not only will he not see them such as indeed they are, but will even account them the contraries of what they are. Wherefore he added, "for they are foolishness unto him." But this comes not of the nature of the things, but of his infirmity, unable as he is to attain to their greatness through the eyes of his soul. It is necessary then to lay it aside first. "What then," some man will say; "is the wisdom from without stigmatized? And yet it is the work of God." How is this clear? since He made it not, but it was an invention of thine. For in this place he calls by the term "wisdom" curious research and superfluous elegance of words. But should any one say that he means the human understanding; even in this sense the fault is thine. For thou bringest a bad name upon it, who makest a bad use of it; who to the injury and thwarting of God demandest from it things which indeed it never had. Since then thou boastest therein and fightest with God, He hath exposed its weakness. For strength of body also is an excellent thing, but when Cain used it not as he ought, God disabled him and made him tremble. Wine also is a good thing; but because the Jews indulged in it immoderately, God prohibited the priests entirely from the use of the fruit. And since thou also hast abused wisdom unto the rejecting of God, and hast demanded of it more than it can do of its own strength; in order to withdraw thee from human hope, he hath shewed thee its weakness. For he is "a natural man, who attributes every thing to reasonings of the mind and considers not that he needs help from above; which is a mark of sheer folly. For God bestowed it that it might learn and receive help from Him, not that it should consider itself sufficient unto itself. For eyes are beautiful and useful, but should they choose to see without light, their beauty profits them nothing; nor yet their natural force, but even doth harm. So if you mark it, any soul also, if it choose to see without the Spirit, becomes even an impediment unto itself. "How then, before this," it will be said, "did she see all things of herself?" Never at any time did she this of herself but she had creation for a book set before her in open view. But when men having left off to walk in the way which God commanded them, and by the beauty of visible objects to know the Great Artificer, had entrusted to disputations the leading-staff of knowledge; they became weak and sank in a sea of ungodliness; for they presently brought in that which was the abyss of all evil, asserting that nothing was produced from things which were not, but from uncreated matter; and from this source they became the parents of ten thousand heresies. Moreover, in their extreme absurdities they agreed; but in those things wherein they seemed to dream out something wholesome, though it were only as in shadows, they fell out with one another; that on both sides they might be laughed to scorn. For that out of things which are not nothing is produced, nearly all with one accord have asserted and written; and this with great zeal. In these absurdities then they were urged on by the Devil. But in their profitable sayings, wherein they seemed, though it were but darkly, to find some part of what they sought, in these they waged war with one another: for instance, that the soul is immortal; that virtue needs nothing external; and that the being good or the contrary is not of necessity nor of fate. Dost thou see the craft of the Devil? If any where he saw men speaking any thing corrupt, he made all to be of one mind; but if any where speaking any thing sound, he raised up others against them; so that the absurdities did not fail, being confirmed by the general consent, and the profitable parts died away, being variously understood. Observe how in every respect the soul is unstrung, and is not sufficient unto herself. — Homily on 1 Corinthians 7 Pope Urban I : We receive of the Holy Spirit in order that we may be made spiritual; for the natural man receiveth not the things of the Spirit of God. Tatian the Assyrian : The perfect God is without flesh; but man is flesh. The bond of the flesh is the soul; that which encloses the soul is the flesh. Such is the nature of man's constitution; and, if it be like a temple, God is pleased to dwell in it by the spirit, His representative; but, if it be not such a habitation, man excels the wild beasts in articulate language only,—in other respects his manner of life is like theirs, as one who is not a likeness of God. But none of the demons possess flesh; their structure is spiritual, like that of fire or air. And only by those whom the Spirit of God dwells in and fortifies are the bodies of the demons easily seen, not at all by others,—I mean those who possess only soul; for the inferior has not the ability to apprehend the superior. — Address of Tatian to the Greeks, Chapter XV Tertullian : Accordingly, God is then especially great, when He is small to man; then especially good, when not good in man's judgment; then especially unique, when He seems to man to be two or more. Now, if from the very first "the natural man, not receiving the things of the Spirit of God," has deemed God's law to be foolishness, and has therefore neglected to observe it; and as a further consequence, by his not having faith, "even that which he seemeth to have hath been taken from him" -such as the grace of paradise and the friendship of God, by means of which he might have known all things of God, if he had continued in his obedience-what wonder is it, if he, reduced to his material nature, and banished to the toil of tilling the ground, has in his very labour, downcast and earth-gravitating as it was, handed on that earth-derived spirit of the world to his entire race, wholly natural and heretical as it is, and not receiving the things which belong to God? Or who will hesitate to declare the great sin of Adam to have been heresy, when he committed it by the choice of his own will rather than of God's? Except that Adam never said to his fig-tree, Why hast thou made me thus? He confessed that he was led astray; and he did not conceal the seducer. — Against Marcion Book II Tertullian : For when a man is rapt in the Spirit, especially when he beholds the glory of God, or when God speaks through him, he necessarily loses his sensation, because he is overshadowed with the power of God,-a point concerning which there is a question between us and the carnally-minded. Now, it is no difficult matter to prove the rapture of Peter. — Against Marcion Book IV Tertullian : However, even (Adam) himself at that time, reverting to the condition of a Psychic after the spiritual ecstasy in which he had prophetically interpreted that "great sacrament" with reference to Christ and the Church, and no longer being "capable of the things which were the Spirit's," yielded more readily to his belly than to God, heeded the meat rather than the mandate, and sold salvation for his gullet! He ate, in short, and perished; saved (as he would) else (have been), if he had preferred to fast from one little tree: so that, even from this early date, animal faith may recognise its own seed, deducing from thence onward its appetite for carnalities and rejection of spiritualities. — On Fasting Theodoret of Cyrus : The unspiritual man is one who is happy enough with his own ideas and who neither accepts nor understands the teaching of the Spirit. — COMMENTARY ON THE FIRST EPISTLE TO THE CORINTHIANS 178
