Cyril of AlexandriaCommentary on the Gospel of John, Book 8 (Fragments) · Written before 444.
It was not however with intent to fulfil the prophecies that the Jews slew the Lord, for in that case they would not have been impious; but it was by reason of their own malignity. For although the prophets foretold the things which were certainly to be brought to pass by their determined evil counsel, they foretold it for this cause, that the sober might leap over the pitfalls of the devil: for surely they who heard might also have taken heed. On which, account also the prediction was needful. That it was not God Who blinded the Jews.
This site's exposition
so many signs in their presence
on John 12:37-41
John steps out of the account to answer why Israel did not believe. He reaches for Isaiah 53:1 on unbelief and Isaiah 6:10 on a hardening that follows long refusal. Verse 41 puts the throne room vision of Isaiah 6 on Jesus.
This site's exposition
He has blinded their eyes
John gives the words of Isaiah in his own form. Augustine and Chrysostom read He has blinded their eyes as God leaving those who first turned from Him. Barnes reads it as a truth preached that hardened hearts set against seeing and understanding, and Clarke applies it to the nation.
The record, by era
The Church Fathers5 voices
(Tr. liii. 5) But what follows involved a deeper question: Therefore they could not believe, because that Esaias said again, He hath blinded their eyes, and hardened their hearts, that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them. That they should not believe; but if so, what sin is there in a man doing what he cannot help doing? And what is a graver point still, the cause is assigned to God; since He it is who blinded their eyes, and hardened their heart. This is not said to be the devil's doing, but God's. Yet if any ask why they could not believe, I answer, Because they would not. For as it is to the praise of the Divine will that God cannot deny Himself, so is it the fault of the human will that they could not believe.
But the words of the Gospel also, that follow, are still more pressing, and start a question of more profound import: for He goes on to say, "Therefore they could not believe, because that Isaiah said again, He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them." For it is said to us: If they could not believe, what sin is it in man not to do what he cannot do and if they sinned in not believing, then they had the power to believe, and did not use it. If, then, they had the power, how says the Gospel, "Therefore they could not believe, because that Isaiah said again, He hath blinded their eyes, and hardened their heart;" so that (which is of grave import) to God Himself is referred the cause of their not believing, inasmuch as it is He who "hath blinded their eyes, and hardened their heart"? "They could not believe," because that Isaiah the prophet foretold it; and the prophet foretold it because God foreknew that such would be the case. But if I am asked why they could not, I reply at once, because they would not; for certainly their depraved will was foreseen by God, and foretold through the prophet by Him from whom nothing that is future can be hid.
But the prophet, sayest thou, assigns another cause than that of their will. What cause does the prophet assign? That "God hath given them the spirit of remorse, eyes that they should not see, and ears that they should not hear; and hath blinded their eyes, and hardened their heart." This also, I reply, their will deserved. For God thus blinds and hardens, simply by letting alone and withdrawing His aid: and God can do this by a judgment that is hidden, although not by one that is unrighteous. This is a doctrine which the piety of the God-fearing ought to preserve unshaken and inviolable in all its integrity: even as the apostle, when treating of the same intricate question, says, "What shall we say then? is there unrighteousness with God? God forbid." If, then, we must be far from thinking that there is unrighteousness with God, this only can it be, that, when He giveth His aid, He acteth mercifully; and, when He withholdeth it, He acteth righteously: for in all He doeth, He acteth not rashly, but in accordance with judgment.
Through them, to wit, had "the heart of the People been made thick, lest they should see with the eyes, and hear with the ears, and understand with a heart" obstructed by the "fats" of which He had expressly forbidden the eating, teaching man not to be studious of the stomach.
(Hom. lxviii) For He does not leave us, except we wish Him, as He saith in Hosea, Seeing thou hast forgotten the law of thy God, I will also forget thy children. (Hos. 4:6) Whereby it is plain that we begin to forsake first, and are the cause of our own perdition. For as it is not the fault of the sun, that it hurts weak eyes, so neither is God to blame for punishing those who do not attend to His words.

That it was not God Who blinded the Jews. For else He would not have required them to give account thereof, forasmuch as He surely pardons involuntary offences. But the meaning is on this wise.
(Tr. liii. 5) But the Prophet, you say, mentions another cause, not their will; viz. that God had blinded their eyes, and hardened their heart. But I answer, that they well deserved this. For God hardens and blinds a man, by forsaking and not supporting him; and this He may by a secret sentence, by an unjust one He cannot. (Tr. liii. 11) And be converted, and I should heal them. Is not to be understood here, from the beginning of the sentence—that they should not see with their eyes, nor understand with their hearts, nor be converted; conversion being the free gift of God? or shall we suppose that a heavenly remedy is meant; whereby those who wished to establish their own righteousness, were so far deserted and blinded, as to stumble on the stumbling stone, till, with confusion of face, they humbled themselves, and sought not their own righteousness which puffeth up the proud, but God's righteousness, which justifieth the ungodly. For many of those who put Christ to death, were afterward troubled with a sense of their guilt; which led to their believing in Him.

And I should heal them - This verse is taken from Isa 6:9, and, perhaps, refers more to the judgments that should fall upon them as a nation, which God was determined should not be averted, than it does to their eternal state. To suppose that the text meant that God was unwilling that they should turn unto him, lest he should be obliged to save them, is an insupportable blasphemy.

The lesson of the words is generally applicable to the whole professing Church of Christ. Its time for doing good in the world is short and limited. The throne of grace will not always be standing—it will be removed one day, and the throne of judgment will be set up in its place. The door of salvation by faith in Christ will not always be open—it will be shut one day forever, and the number of God's elect will be completed.
THE BLINDNESS of Israel concerning our Lord was sadly remarkable. It was a blindness of the eyes, for they saw his many miracles, and yet believed not: their ears also seemed to be stopped, for they heard his words and did not understand them; and their hearts also were heavy, for they did not relent under the plaintive admonitions of a Saviour's love. Their hearts were cruel towards the Messiah; they hated him without a cause.

The door of salvation by faith in Christ will not always be open—it will be shut one day forever, and the number of God's elect will be completed. The fountain for all sin and uncleanness will not always be accessible; the way to it will one day be barred, and there will remain nothing but the lake that burns with fire and brimstone. These are solemn thoughts; but they are true. They cry aloud to sleeping Churchmen and drowsy congregations, and ought to arouse great searchings of heart. "Can nothing more be done to spread the Gospel at home and abroad? Has every means been tried for extending the knowledge of Christ crucified? Can we lay our hands on our hearts, and say that the Churches have left nothing undone in the matter of missions? Can we look forward to the Second Advent with no feelings of humiliation, and say that the talents of wealth, and influence, and opportunities have not been buried in the ground?" Such questions may well humble us, when we look, on one side, at the state of professing Christendom, and, on the other, at the state of the heathen world. We must confess with shame that the Church is not walking worthy of its light. But the lesson of the words is specially applicable to ourselves as individuals . Our own time for getting good is short and limited; let us take heed that we make good use of it. Let us "walk while we have the light." Have we Bibles? Let us not neglect to read them. Have we the preached Gospel? Let us not linger halting between two opinions, but believe to the saving of our souls. Have we Sabbaths?
THE BLINDNESS of Israel concerning our Lord was sadly remarkable. It was a blindness of the eyes, for they saw his many miracles, and yet believed not: their ears also seemed to be stopped, for they heard his words and did not understand them; and their hearts also were heavy, for they did not relent under the plaintive admonitions of a Saviour's love. Their hearts were cruel towards the Messiah; they hated him without a cause. No door was open to the heart of Israel; they had hardened their heart, they had shut their eyes, they had stopped their ears, and even he that spake as never man spake gained no access to their souls. They went so far as to crucify him, and cried as they did so, "His blood be on us, and our children,"—words so sadly verified when Jerusalem was destroyed, and her children slaughtered, sold as slaves, or scattered to the four corners of the earth. It was indeed, a terrible blindness which happened unto Israel. Her rejection of the Lord Jesus is the more amazing because Isaiah gave so clear an account of the Messiah, and so clearly pictured Jesus of Nazareth. Descriptions of him could not have been more explicit than were the prophecies of Isaiah. It would be very easy to construct an entire life of Christ out of the book of Isaiah, beginning with "a virgin shall conceive and bear a son, and shall call his name Immanuel," and ending with "he made his grave with the wicked and with the rich in his death." Isaiah spake of John the Baptist as the "voice crying in the wilderness, prepare ye the way of the Lord, make straight in the desert a highway for our God," and he foretold our Lord's ministry by the way of the sea beyond Jordan in Galilee of the Gentiles, where the people who sat in darkness saw great light.

He hath blinded their eyes - The expression in Isaiah is, “Go, make the heart of this people fat, and shut their eyes.” That is, go and proclaim truth to them truth that will result in blinding their eyes. Go and proclaim the law and the will of God, and the effect will be, owing to the hardness of their heart, that their eyes will be blinded and their hearts hardened. As God knew that this would be the result - as it was to be the effect of the message, his commanding Isaiah to go and proclaim it was the same in effect, or in the result, as if he had commanded him to blind their eyes and harden their hearts. It is this effect or result to which the evangelist refers in this place. He states that God did it, that is, he did it in the manner mentioned in Isaiah, for we are limited to that in our interpretation of the passage. In that case it is clear that the mode specified is not a direct agency on the part of God in blinding the mind - which we cannot reconcile with any just notions of the divine character - but “in suffering the truth to produce a regular effect on sinful minds, without putting forth any positive supernatural influence to prevent it.” The effect of truth on such minds is to irritate, to enrage, and to harden, unless counteracted by the grace of God. See Rom 7:8-9, Rom 7:11; 2Co 2:15-16. And as God knew this, and, knowing it, still sent the message, and suffered it to produce the regular effect, the Evangelist says “he hath blinded their minds,” thus retaining the substance of the passage in Isaiah without quoting the precise language; but in proclaiming the truth there was nothing wrong on the part of God or of Isaiah, nor is there any indication that God was unwilling that they should believe and be saved. That they should not see ... […]
