But after the fall he no longer remained according to the spirit, though the spirit was still in him. It raised its voice, but men did not listen to it. Such are all who have not yet risen from the fall.
A man begins to be according to the spirit only after receiving grace, when he has been regenerated. Then the spirit enters its own rank, gains strength, and governs everything in man.
It determines by itself the norm of his life. Such a man has only one concern: to be unceasingly in God by the spirit, and to direct everything toward what is pleasing to Him.”
The one who exists according to the spirit and keeps spiritual-mindedness is in living union with the Source of all life. He is filled with every true life.
This life brings into harmony all manifestations of his own life, both inward and outward. It introduces into it a peace and harmony more beautiful, sweet, and delightful than man can imagine.
By contrast, carnal-mindedness is life at a distance from God and in forgetfulness of Him. It is the life of pleasure-loving self-pleasing, moved and tossed by the passions.
It makes human nature impoverished. It introduces discord into this nature, decomposing and corroding it. Both conditions make themselves felt by a languor resembling the agony of one dying.
“His soul,” says Theophan of the carnally minded man, “has no inclination toward God and divine things. This lack of inclination of the soul toward the divine is the lightest outer limit of enmity against God.
The heaviest outer limit is an active uprising with fury against the divine order. Disobedience to the law of God is, in general, the distinguishing mark of carnal-mindedness.
Carnal-mindedness, while it remains such, cannot submit to the law of God. For as soon as it submitted, it would cease to be carnal-mindedness.”
Concerning this infirmity, St. John Chrysostom says: “Do not be troubled when you hear, ‘nor indeed can be.’ This difficulty can still be easily removed.
By carnal-mindedness the Apostle here means a mind made earthly and attached to worldly and evil deeds. Of this the Apostle says that it cannot submit to God, not of man in general.
So also Christ says in the Gospel, ‘A bad tree cannot bear good fruit’ (Mt 7:18). He did not say that a bad tree cannot become good.
He says that while it remains bad, it cannot bear good fruit.”
As men of the flesh cannot serve the spirit, because the Spirit of God is not in them (cf. Gen 6:3), so, conversely, men guided by the spirit cannot live carnally, that is, live for sin.
This is because the Holy Spirit lives in them and guides them into all truth. Here, among other things, the Holy Spirit is called the Spirit of Christ.
Catholics base on this their teaching concerning the procession of the Spirit from the Father and the Son. Yet here there is not even a hint of the Spirit’s procession from the Son.
He is called Christ’s because He is given to us for the sake of Christ’s merits and through His intercession.
“I will pray the Father,” Jesus Christ said, “and He will send you the Spirit, the Comforter, Who proceeds from the Father. He will teach you all things” (Jn 14:26; 15:26).
St. John Chrysostom says: “The Apostle does not call the Spirit Christ. Rather, he gives us to understand that the one who has the Spirit is not only called Christ’s, but even has Christ Himself within him.
For it is impossible that Christ should not be where the Spirit is. Where one of the Persons of the Trinity is, there is the whole Trinity. Thus She is indivisible in Herself and most closely united.”
