Colossians 3:10

"Seeing that ye have put off the old man with his doings, and have put on the new man, which is being renewed unto knowledge after the image of Him that created him." It is worth enquiring here, what can be the reason why he calls the corrupt life, "members," and "man," and "body," and again the virtuous life, the same. And if "the man" means "sins," how is it that he saith, "with his doings"? For once he said, "the old man," showing that this is not man, but the other. The moral choice doth rather determine one than the substance, and is rather "man" than the other. For his substance casteth him not into hell, nor leadeth him into the kingdom, but men the themselves: and we neither love nor hate any one so far as he is man, but so far as he is such or such a man. If then the substance be the body, and in either sort cannot be accountable, how doth he say that it is evil? But what is that he saith, "with his doings"? He means the choice, with the acts. And he calleth him "old," on purpose to show his deformity, and hideousness, and imbecility; and "new," as if to say, Do not expect that it will be with this one even as with the other, but the reverse: for ever as he farther advances, he hasteneth not on to old age, but to a youthfulness greater than the preceding. For when he hath received a fuller knowledge, he is both counted worthy of greater things, and is in more perfect maturity, in higher vigor; and this, not from youthfulness alone, but from that "likeness" also, "after" which he is. Lo! the best life is styled a creation, after the image of Christ: for this is the meaning of, "after the image of Him that created him," for Christ too came not finally to old age, but was so beautiful as it is not even possible to tell.

One royal form it hath, that, namely, of Christ. They whom he has in view, appear to me rather to be of the Gentiles. For like as earth, being but sand, even though one part be greater, another less, losing its own previous form, doth afterwards become gold; and like as wool, of whatever kind it be, receiveth another aspect, and hides its former one: so truly is it also with the faithful.

But the apostle himself also, being one who had been formed in a womb, and had issued thence, wrote to us, and confessed in his Epistle to the Philippians that "to live in the flesh was the fruit of [his] work;" thus expressing himself. Now the final result of the work of the Spirit is the salvation of the flesh. For what other visible fruit is there of the invisible Spirit, than the rendering of the flesh mature and capable of incorruption?

The new man is the will according to God; it does not grow old, but more and more blossoms and grows in the knowledge of God and of divine things, always and ever appearing more youthful and yet all the more strengthened, the fuller the …

The new nature or self is the mind, renewed from within, because before grace our mind is subject within to sin, and when it is renewed by grace it becomes new: "Your youth is renewed like the eagle's" (Ps 103:5); "For neither circumcision counts for …
