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.

If, however, any one say, "What then? Could not God have exhibited man as perfect from beginning?" let him know that, inasmuch as God is indeed always the same and unbegotten as respects Himself, all things are possible to Him. But created things must be inferior to Him who created them, from the very fact of their later origin; for it was not possible for things recently created to have been uncreated. But inasmuch as they are not uncreated, for this very reason do they come short of the perfect. Because, as these things are of later date, so are they infantile; so are they unaccustomed to, and unexercised in, perfect discipline. For as it certainly is in the power of a mother to give strong food to her infant, [but she does not do so], as the child is not yet able to receive more substantial nourishment; so also it was possible for God Himself to have made man perfect from the first, but man could not receive this [perfection], being as yet an infant. And for this cause our Lord in these last times, when He had summed up all things into Himself, came to us, not as He might have come, but as we were capable of beholding Him. He might easily have come to us in His immortal glory, but in that case we could never have endured the greatness of the glory; and therefore it was that He, who was the perfect bread of the Father, offered Himself to us as milk, [because we were] as infants. He did this when He appeared as a man, that we, being nourished, as it were, from the breast of His flesh, and having, by such a course of milk nourishment, become accustomed to eat and drink the Word of God, may be able also to contain in ourselves the Bread of immortality, which is the Spirit of the Father.

And on this account does Paul declare to the Corinthians, "I have fed you with milk, not with meat, for hitherto ye were not able to bear it." That is, ye have indeed learned the advent of our Lord as a man; nevertheless, because of your infirmity, the Spirit of the Father has not as yet rested upon you. "For when envying and strife," he says, "and dissensions are among you, are ye not carnal, and walk as men?" That is, that the Spirit of the Father was not yet with them, on account of their imperfection and shortcomings of their walk in life. As, therefore, the apostle had the power to give them strong meat-for those upon whom the apostles laid hands received the Holy Spirit, who is the food of life [eternal]-but they were not capable of receiving it, because they had the sentient faculties of the soul still feeble and undisciplined in the practice of things pertaining to God; so, in like manner, God had power at the beginning to grant perfection to man; but as the latter was only recently created, he could not possibly have received it, or even if he had received it, could he have contained it, or containing it, could he have retained it. It was for this reason that the Son of God, although He was perfect, passed through the state of infancy in common with the rest of mankind, partaking of it thus not for His own benefit, but for that of the infantile stage of man's existence, in order that man might be able to receive Him. There was nothing, therefore, impossible to and deficient in God, [implied in the fact] that man was not an uncreated being; but this merely applied to him who was lately created, [namely] man.

For it was requisite that certain facts should be announced beforehand by the fathers in a paternal manner, and others prefigured by the prophets in a legal one, but others, described after the form of Christ, by those who have received the adoption; while in one God are all things shown forth. For although Abraham was one, he did in himself prefigure the two covenants, in which some indeed have sown, while others have reaped; for it is said, "In this is the saying true, that it is one 'people' who sows, but another who shall reap;" but it is one God who bestows things suitable upon both-seed to the sower, but bread for the reaper to eat. Just as it is one that planteth, and another who watereth, but one God who giveth the increase. For the patriarchs and prophets sowed the word [concerning] Christ, but the Church reaped, that is, received the fruit. For this reason, too, do these very men (the prophets) also pray to have a dwelling-place in it, as Jeremiah says, "Who will give me in the desert the last dwelling-place?" in order that both the sower and the reaper may rejoice together in the kingdom of Christ, who is present with all those who were from the beginning approved by God, who granted them His Word to be present with them.
