Ephesians 4:24

The divine apostle more clearly sets before us by his own words when he charges us, "Put ye on the Lord Jesus Christ," and also where (using the same word) he says, "Put on the new man which after God is created." For if the garment of salvation is one, and that is Christ, one cannot say that "the new man, which after God is created," is any other than Christ, but it is clear that he who has "put on Christ" has "put on the new man which after God is created." For actually He alone is properly named "the new man," Who did not appear in the life of man by the known and ordinary ways of nature, but in His case alone creation, in a strange and special form, was instituted anew.

He is calling us to live as one whose thoughts come from the Spirit, who is himself once again becoming the spiritual man created by God. We are to live in the likeness of God, just as God intended when he said: "Let us make …

"And put on the new man." Seest thou that the subject is one, but the clothing is twofold, that which is put off, and that which is put on? "The new man," he continues, "which after God hath been created in righteousness and holiness of truth." Now wherefore does he call virtue a man? And wherefore vice, a man? Because a man cannot be shown without acting; so that these things, no less than nature, show a man, whether he be good or evil. Now as to undress one's self and to dress one's self is easy, so may we see it is with virtue and vice. The young man is strong; wherefore let us also become strong for the performance of good actions. The young man has no wrinkle, therefore neither should we have. The young man wavers not, nor is he easily taken with diseases, therefore neither should we be. Observe here how he calls this realizing of virtue, this bringing of it into being from nothing, a "creation." But what? was not that other former creation after God? No, in nowise, but after the devil. He is the sole creator of sin. How is this? For man is created henceforth, not of water, nor of earth, but "in righteousness and holiness of truth." What is this? He straightway created him, he means, to be a son: for this takes place from Baptism. This it is which is the reality, "in righteousness and holiness of truth." There was of old a righteousness, there was likewise a holiness with the Jews. Yet was that righteousness not in truth, but in figure. For the being clean in body was a type of purity, not the truth of purity; was a type of righteousness, not the truth of righteousness. "In righteousness," saith he, "and holiness," which are "of truth." And this expression is used with reference to falsehood; for many there are, who to them that are without, seem to be righteous, yet are false. Now by righteousness is meant universal virtue. […]

Our part then is, never to put off the garment of righteousness, which also the Prophet calls, "the garment of salvation," that so we may be made like unto God. For He indeed hath put on righteousness. This garment let us put on. Now the word, "put on," plainly declares nothing else, than that we should never at all put it off. For hear the Prophet, where he saith, "He clothed himself also with cursing as with his garment, and it came into his inward parts." And again, "Who coverest Thyself with light as with a garment." And again, it is usual with us to speak concerning men, such an one has "put on" such an one. So then it is not for one day, nor for two, nor for three, but he would have us ever arrayed in virtue, and never stripped of this garment. For a man is not so disfigured when he is stripped of his clothing, as when he is stripped of his virtue. In the former case his fellow-servants behold his nakedness, in the latter his Lord and the Angels. If ever thou happen to see any one going out naked through the public square, tell me, art thou not distressed? When then thou goest about stripped of this garment, what shall we say? Seest not those beggars whom we are wont to call strollers, how they roam about, how we pity even them? And yet nevertheless they are without excuse. We do not excuse them when they have lost their clothes by gaming; and how then, if we lose this garment, shall God pardon us? For whenever the devil sees a man stripped of his virtue, he straightway disguises and disfigures his face, and wounds him, and drives him to great straits. Let us strip ourselves of our riches, that we be not stripped of righteousness. The garb of wealth mars this garment. It is a robe of thorns. Thorns are of this nature; and the more closely they are wrapped around us, the more naked are we made. […]

Do you see that the subject is one and the same, which draws into itself and is clothed upon, but the garments are different, namely vice and virtue? For just as it is easy to undress and dress, so too are vice and virtue easy, …
