2 Corinthians 4:4

As to their affirming that Paul said plainly in the Second .
In accordance with this word, therefore, does the apostle say, in the Second the] to the Corinthians: "In whom the this world hath blinded the minds of them that believe not, lest the light of the glorious Gospel of Christ should shine

The latter method has been adopted by Marcion, by reading the passage which follows, "in whom the God of this world," as if it described the Creator as the God of this world, in order that he may, by these words, imply that there is another God for the other world.

Now the countenance (or person ) of the Lord here is Christ. Wherefore the apostle said above: Christ, who is the image of God." Since Christ, then, is the person of the Creator, who said, "Let there be light," it follows that Christ and the apostles, and the gospel, and the veil, and Moses-nay, the whole of the dispensations-belong to the God who is the Creator of this world, according to the testimony of the clause (above adverted to), and certainly not to him who never said, "Let there be light.

Who then is he? Undoubtedly he who has raised up "children of disobedience" against the Creator Himself ever since he took possession of that "air" of His; even as the prophet makes him say: "I will set my throne above the stars; ... I will go up above the clouds; I will be like the Most High." This must mean the devil, whom in another passage (since such will they there have the apostle's meaning to be) we shall recognize in the appellation the god of this world. For he has filled the whole world with the lying pretence of his own divinity.

For if it is a Christian who, after wandering far from his Father, squanders, by living heathenishly, the "substance" received from God his Father,-(the substance), of course, of baptism-(the substance), of course, of the Holy Spirit, and (in consequence) of eternal hope; if, stripped of his mental "goods," he has even handed his service over to the prince of the world -who else but the devil?-and by him being appointed over the business of "feeding swine"-of tending unclean spirits, to wit-has recovered his senses so as to return to his Father,-the result will be, that, not adulterers and fornicators, but idolaters, and blasphemers, and renegades, and every class of apostates, will by this parable make satisfaction to the Father; and in this way (it may) rather (be said that) the whole "substance" of the sacrament is most truly wasted away.

For the Son of God is Word and Righteousness. But every sinner is under the tyranny of the prince of this age, since every sinner is made a friend of the present evil age. For he does not hand himself over to the One who gave “himself for our sins to deliver us from the present evil age” and to deliver us “according to the will of our God and Father,” according to the verse in the letter to the Galatians. And the one who by voluntary sin is under the tyranny of the prince of this age is also ruled by sin. That is why we are commanded by Paul no longer to be subjected to sin that wishes to rule over us. We are so ordered through the following words, “Let not sin therefore reign in your mortal bodies, to make you obey their passions.”.

But if anyone dares to attribute corruption of substance to what was made according to the image and likeness of God, in my opinion he extends the charge of impiety also to the Son of God himself, since he is also called in Scripture “the image of God.” At least the one who holds the opinion will certainly find fault with the authority of Scripture, which says that humanity was made after the image of God. And the traces of the divine image are clearly recognized not through the likeness of the body, which undergoes corruption, but through the intelligence of the soul, its righteousness, temperance, courage, wisdom, discipline, and through the entire chorus of virtues that are present in God by substance and can be in humankind through effort and the imitation of God. The Lord points this out in the Gospel when He says, “Be merciful, even as your Father is merciful” and “Be perfect, as your Father is perfect.” Consequently, it is quite clear that in God all these virtues can never enter or leave, but they are acquired by us little by little and one by one.

When, therefore, the number of men had begun to increase, God in His forethought, lest the devil, to whom from the beginning He had given power over the earth, should by his subtilty either corrupt or destroy men, as he had done at first, sent angels for the protection and improvement of the human race; and inasmuch as He had given these a free will, He enjoined them above all things not to defile themselves with contamination from the earth, and thus lose the dignity of their heavenly nature. He plainly prohibited them from doing that which He knew that they would do, that they might entertain no hope of pardon. Therefore, while they abode among men, that most deceitful ruler of the earth, by his very association, gradually enticed them to vices, and polluted them by intercourse with women. Then, not being admitted into heaven on account of the sins into which they had plunged themselves, they fell to the earth. Thus from angels the devil makes them to become his satellites and attendants. But they who were born from these, because they were neither angels nor men, but bearing a kind of mixed nature, were not admitted into hell, as their fathers were not into heaven. Thus there came to be two kinds of demons; one of heaven, the other of the earth. The latter are the wicked spirits, the authors of all the evils which are done, and the same devil is their prince.

Therefore in this union of heaven and earth, the image of which is developed in man, those things which belong to God occupy the higher part, namely the soul, which has dominion over the body; but those which belong to the devil occupy the lower part, manifestly the body: for this, being earthly, ought to be subject to the soul, as the earth is to heaven.

Paul is saying that God dims the sight of worldly people because they are hostile to the faith of Christ. He is giving them what they want, since it is because they are hostile and tell lies that they move further toward not being able to believe what they do not want to believe. Commentary on Paul’s Epistles.

And the Image, as of one substance with him, and because he is of the Father, and not the Father of him. For this is of the nature of an image, to be the reproduction of its archetype and of that whose name it bears; only that there is more here. For in ordinary language an image is a motionless representation of that which has motion, but in this case it is the living reproduction of the living one and is more exactly like than was Seth to Adam or any son to his father.

Every unbeliever is of this world. No one who has overcome it and been deemed worthy of the world to come is blinded in his understanding, for his eyes have been enlightened.

"That the light of the Gospel of the glory of Christ should not dawn upon them."

Not that they might disbelieve in God, but that unbelief might not see what are the things within, as also He enjoined us, commanding not to "cast the pearls before the swine." For had He revealed even to those who disbelieve, their disease would have been the rather aggravated. For if one compel a man laboring under ophthalmia to look at the sunbeams, he the rather increases his infirmity. Therefore the physicians even shut them up in darkness, so as not to aggravate their disorder. So then here also we must consider that these persons indeed became unbelievers of themselves, but having become so, they no longer saw the secret things of the Gospel, God thenceforth excluding its beams from them. As also he said to the disciples, "Therefore I speak unto them in proverbs, because hearing they hear not." But what I say may also become clearer by an example; suppose a Greek, accounting our religion to be fables. This man then, how will he be more advantaged? by going in and seeing the mysteries, or by remaining without? Therefore he says, "That the light should not dawn upon them," still dwelling on the history of Moses. For what happened to the Jews in his case, this happeneth to all unbelievers in the case of the Gospel. And what is that which is overshadowed, and which is not illuminated unto them? Hear him saying, "That the light of the glorious Gospel of Christ who is the Image of God, should not dawn upon them." Namely, that the Cross is the salvation of the world, and His glory; that this Crucified One himself is about to come with much splendor; all the other things, those present, those to come, those seen, those not seen, the unspeakable splendor of the things looked for. Therefore also he said, "dawn," that thou mayest not look for the whole here, for that which is [here] given is only, as it were, a little dawning of the Spirit. Therefore, also above as indicating this, he spoke of "savor;" and again, "earnest," showing that the greater part remaineth there. But nevertheless all these things have been hidden from them; but had been hidden because they disbelieved first. Then to show that they are not only ignorant of the Glory of Christ, but of the Father's also, since they know not His, he added, "Who is the Image of God?" For do not halt at Christ only. For as by Him thou seest the Father, so if thou art ignorant of His Glory, neither wilt thou know the Father's.

Then because the unbelievers knew not its power, he added, this is no fault of ours, but of their own insensibility. Wherefore also he saith,

"But if our Gospel is veiled, it is veiled in them that are lost; in whom the God of this world hath blinded the eyes of the unbelieving."

As he said also before, "To some a savor from death unto death, to others a savor from life unto life," so he saith here too. But what is "the God of this world?" Those that are infected with Marcion's notions, affirm that this is said of the Creator, the just only, and not good; for they say that there is a certain God, just and not good. But the Manichees say that the devil is here intended, desiring from this passage to introduce another creator of the world besides the True One, very senselessly. For the Scripture useth often to employ the term God, not in regard of the dignity of that so designated, but of the weakness of those in subjection to it; as when it calls Mammon lord, and the belly god. But neither is the belly therefore God, nor Mammon Lord, save only of those who bow down themselves to them. But we assert of this passage that it is spoken neither of the devil nor of another creator, but of the God of the Universe, and that it is to be read thus; "God hath blinded the minds of the unbelievers of this world." For the world to come hath no unbelievers; but the present only. But if any one should read it even otherwise, as, for instance, "the God of this world;" neither doth this afford any handle, for this doth not show Him to be the God of this world only. For He is called "the God of Heaven," yet is He not the God of Heaven only; and we say, 'God of the present day;' yet we say this not as limiting His power to it alone. And moreover He is called the "God of Abraham, and the God of Isaac, and the God of Jacob;" and yet He is not the God of them alone. And one may find many other like testimonies in the Scriptures. How then "hath" He "blinded" them? Not by working unto this end; away with the thought! but by suffering and allowing it. For it is usual with the Scripture so to speak, as when it saith, "God gave them up unto a reprobate mind." For when they themselves first disbelieved, and rendered themselves unworthy to see the mysteries; He Himself also thereafter permitted it. But what did it behove Him to do? To draw them by force, and reveal to those who would not see? But so they would have despised the more, and would not have seen either.

The god of this world may be understood to be the devil, on the ground that he has claimed to rule over unbelievers. Or, on account of the attacks of the heretics it may be understood to mean that God has blinded the minds of unbelievers precisely because of their unbelief.

What is the face of God like? As his image, certainly, for as the apostle says, the image of the Father is the Son. With his image, therefore, may he shine upon us, that is, may he shine his image, the Son, upon us in order that he himself may shine upon us, for the light of the Father is the light of the Son. He who sees the Father sees also the Son, and he who sees the Son sees also the Father. Where there is no diversity between glory and glory, there glory is one and the same.

Paul is saying that unbelief is limited to this world, because in the next life the truth will be plain to everyone.

A hermit said, ‘When the donkey’s eyes are covered it walks round the mill-wheel. If you uncover its eyes, it will not go on walking in the circle. So if the devil succeeds in covering a man’s eyes, he leads him into every kind of sin. But if the man’s eyes are uncovered, he can more easily escape.’
