Ver. 7. “Because the carnal mind is enmity against God:” and this is worse than death. Then to show how it is at once death and enmity; “for it is not subject to the Law of God,” he says, “neither indeed can be.” But be not troubled at hearing the “neither indeed can be.” For this difficulty admits of an easy solution. For what he here names “carnal mindedness” is the reasoning (or “way of thinking,” λογισμὸν) that is earthly, gross, and eager-hearted after the things of this life and its wicked doings. It is of this he says “neither yet can” it “be subject” to God. And what hope of salvation is there left, if it be impossible for one who is bad to become good? This is not what he says. Else how would Paul have become such as he was? How would the (penitent) thief, or Manasses, or the Ninevites, or how would David after falling have recovered himself? How would Peter after the denial have raised himself up? How could he that had lived in fornication have been enlisted among Christ's fold? How could the Galatians who had “fallen from grace”, have attained their former dignity again? What he says then is not that it is impossible for a man that is wicked to become good, but that it is impossible for one who continues wicked to be subject to God. Yet for a man to be changed, and so become good, and subject to Him, is easy. For he does not say that man cannot be subject to God, but, wicked doing cannot be good. As if he had said, fornication cannot be chastity, nor vice virtue. And this it says in the Gospel also, “A corrupt tree cannot bring forth good fruit”, not to bar the change from virtue to vice, but to say how incapable continuance in vice is of bringing forth good fruits. For He does not say that an evil tree cannot become a good one, but that bring forth good fruit it cannot, while it continues evil. For that it can be changed, He shows from this passage, and from another parable, when He introduces the tares as becoming wheat, on which score also He forbids their being rooted up; “Lest,” He says, “ye root up also the wheat with them”; that is, that which will spring (γίνεσθαι, 4 manuscripts τίκτεσθαι) from them. It is vice then he means by carnal mindedness, and by spiritual mindedness the grace given, and the working of it discernible in the right determination of mind, not discussing in any part of this passage, a substance and an entity, but virtue and vice. For that which you had no power to do under the Law, now, he means, you will be able to do, to go on uprightly, and with no intervening fall, if you lay hold of the Spirit's aid. For it is not enough not to walk after the flesh, but we must also go after the Spirit, since turning away from what is evil will not secure our salvation, but we must also do what is good. And this will come about, if we give our souls up to the Spirit, and persuade our flesh to get acquainted with its proper position, for in this way we shall make it also spiritual; as also if we be listless we shall make our soul carnal. For since it was no natural necessity which put the gift into us, but the freedom of choice placed it in our hands, it rests with you henceforward whether this shall be or the other. For He, on His part, has performed everything. For sin no longer wars against the law of our mind, neither does it lead us away captive as heretofore, for all that state has been ended and broken up, and the affections cower in fear and trembling at the grace of the Spirit. But if you will quench the light, and cast out the holder of the reins, and chase the helmsman away, then charge the tossing thenceforth upon yourself. For since virtue has been now made an easier thing (for which cause also we are under far stricter obligations of religious living), consider how men's condition lay when the Law prevailed, and how at present, since grace has shone forth. The things which aforetime seemed not possible to any one, virginity, and contempt of death, and of other stronger sufferings, are now in full vigor through every part of the world, and it is not with us alone, but with the Scythians, and Thracians, and Indians, and Persians, and several other barbarous nations, that there are companies of virgins, and clans of martyrs, and congregations of monks, and these now grown even more numerous than the married, and strictness of fasting, and the utmost renunciation of property. Now these are things which, with one or two exceptions, persons who lived under the Law never conceived even in a dream. Since you see then the real state of things voiced with a shriller note than any trumpet, let not yourself grow soft and treacherous to so great a grace. Since not even after the faith is it possible for a listless man to be saved! For the wrestlings are made easy that you may strive and conquer, nor that you should sleep, or abuse the greatness of the grace by making it a reason for listlessness, so wallowing again in the former mire. And so he goes on to say,
Ver. 8. “So then they that are in the flesh cannot please God.”
What then? Are we, it will be said, to cut our bodies in pieces to please God, and to make our escape from the flesh? And would you have us be homicides, and so lead us to virtue? You see what inconsistencies are gendered by taking the words literally. For by “the flesh” in this passage, he does not mean the body, or the essence of the body, but that life which is fleshly and worldly, and uses self-indulgence and extravagance to the full, so making the entire man flesh. For as they that have the wings of the Spirit, make the body also spiritual, so do they who bound off from this, and are the slaves of the belly, and of pleasure, make the soul also flesh, not that they change the essence of it, but that they mar its noble birth. And this mode of speaking is to be met with in many parts of the Old Testament also, to signify by flesh the gross and earthly life, which is entangled in pleasures that are not convenient. For to Noah He says, “My Spirit shall not always make its abode in these men, because they are flesh.” And yet Noah was himself also compassed about with flesh. But this is not the complaint, the being compassed about with the flesh, for this is so by nature, but the having chosen a carnal life. Wherefore also Paul says, “But they that are in the flesh cannot please God.” Then he proceeds:
Ver. 9. “But you are not in the flesh, but in the Spirit.”
