40 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.
(Hom. lxviii. 1) But why did He hide Himself, when they neither took up stones to cast at Him, nor blasphemed? Because He saw into their hearts, and knew the fury they were in; and therefore did not wait till they broke out into act, but retired to give their envy time to subside.
(Hom. lxviii. 1) And thus the Evangelist tacitly explains it, when he adds, But though He had done so many miracles before them, yet they believed not on Him.
(Hom. lxviii. 2) But why then did Christ come? Did He not know that they would not believe in Him? Yes: the Prophets had prohibited this very unbelief, and He came that it might be made manifest, to their confusion and condemnation; That the saying of Esaias the prophet might be fulfilled, which He spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed?
(Hom. lxviii. 2) That the saying of Esaias might be fulfilled: that here is expressive not of the cause, but of the event. They did not disbelieve because Esaias said they would; but because they would disbelieve, Esaias said they would.
(Hom. lxviii. 2) This is a common form of speech among ourselves. I cannot love such a man, meaning by this necessity only a vehement will. The Evangelist says could not, to show that it was impossible that the Prophet should lie, not that it was impossible that they should believe.
(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.
(Hom. lxviii. 2) His glory means the vision of Him sitting on His lofty throne: I saw the Lord sitting upon a throne. Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? (Is. 6:1)
(Tr. liii. 2) It is evident here that the arm of the Lord is the Son of God Himself. Not that the Father has a human fleshly form; He is called the arm of the Lord, because all things were made by Him. If a man had power of such a kind, as that without any motion of his body, what he said was forthwith done, the word of that man would be his arm. Here is no ground to justify, however, the error of those who say that the Godhead is one Person only, because the Son is the arm of the Father, and a man and his arm are not two persons, but one. These men do not understand, that the commonest things require to be explained often by applying language to them taken from other things in which there happens to be a likeness, [cand that, when we are upon things incomprehensible, and which cannot be described as they actually are, this is much more necessary. Thus one man calls another man, whom he makes great use of, his arm; and talks of having lost his arm, of having his arm taken away from him.] But some mutter, and ask, What fault was it of the Jews, if it was necessary that the sayings of Esaias should be fulfilled? We answer, that God, foreseeing the future, predicted by the Prophet the unbelief of the Jews, but did not cause it. God does not compel men to sin, because He knows they will sin. He foreknows their sins, not His own. The Jews committed the sin, which He who knows all things foretold they would commit.
(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.
(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? ord, 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. (c. 12). These things said Esaias, when he saw His glory, and spake of Him. He saw Him not really, but figuratively, in prophetic vision. Be not deceived by those who say that the Father is invisible, the Son visible, making the Son a creature. For in the form of God, in which He is equal to the Father, the Son also is invisible; though He took upon Him the form of a servant, that He might be seen by men. Before His incarnation too, He made Himself visible at times to human eyes; but visible through the medium of created matter, not visible as He is.
(Tr. liii. 13) As their faith grew, their love of human praise grew still more, and outstripped it.
Nevertheless, among the chief rulers also many believed on Him; but because of the Pharisees they did not confess Him, lest they should be put out of the synagogue. For they loved the praise of men more than the praise of God. The praise of God is publicly to confess Christ: the praise of men is to glory in earthly things.
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.
Here again is another question, but it is not so if we rightly consider it. For as the sun dazzles the eyes of the weak, not by reason of its proper nature, so it is with those who give not heed to the words of God. Thus, in the case of Pharaoh, He is said to have hardened his heart, and so it is with those who are at all contentious against the words of God. This is a peculiar mode of speech in Scripture, as also the, He gave them over unto a reprobate mind Romans 1:28, and the, He divided them to the nations, that is, allowed, permitted them to go. For the writer does not here introduce God as Himself working these things, but shows that they took place through the wickedness of others. For, when we are abandoned by God, we are given up to the devil, and when so given up, we suffer ten thousand dreadful things. To terrify the hearer, therefore, the writer says, He hardened, and gave over. For to show that He does not only not give us over, but does not even leave us, except we will it, hear what He says, Do not your iniquities separate between Me and you? Isaiah 59:2, Septuagint. And again, They that go far away from You shall perish. Psalm 73:27, Septuagint And Hosea says, You have forgotten the law of your God, and I will also forget you Hosea 4:6, Septuagint; and He says Himself also in the Gospels, How often would I have gathered your children— and you would not. Luke 13:34 Esaias also again, I came, and there was no man; I called, and there was none to hearken. Isaiah 50:2, Septuagint These things He says, showing that we begin the desertion, and become the causes of our perdition; for God not only desires not to leave or to punish us, but even when He punishes, does it unwillingly; I will not, He says, the death of a sinner, so much as that he should turn and live. Ezekiel 18:32, Septuagint Christ also mourns over the destruction of Jerusalem, as we also do over our friends.
3. Knowing this, let us do all so as not to remove from God, but let us hold fast to the care of our souls, and to the love towards each other; let us not tear our own members, (for this is the act of men insane and beside themselves,) but the more we see any ill disposed, the more let us be kind to them. Since we often see many persons suffering in their bodies from difficult or incurable maladies, and cease not to apply remedies. What is worse than gout in foot or hand? Are we therefore to cut off the limbs? Not at all, but we use every means that the sufferer may enjoy some comfort, since we cannot get rid of the disease. This also let us do in the case of our brethren, and, even though they be diseased incurably, let us continue to tend them, and let us bear one another's burdens. So shall we fulfill the law of Christ, and obtain the promised good things, through the grace and lovingkindness of our Lord Jesus Christ, with whom to the Father and the Holy Ghost be glory for ever and ever. Amen.
Just as the sun blinds the eyes of the weak … this is also what happens to those who do not listen to the words of God. As so, in the case of Pharaoh, he is said to have hardened his heart, and so it is with those who are at all contentious against the words of God. This is a peculiar mode of speech of Scripture, as in, “He gave them over to a reprobate mind,” … that is, he allowed or permitted them to go. For the writer does not here introduce God as himself doing these things but shows that they took place through the wickedness of others. For when we are abandoned by God, we are given up to the devil.… It is to terrify the hearer that the writer says “he hardens” and “he gave over.” For to show that he does not give us over or even leave us unless we want him to, listen to what he says, “Isn’t it your iniquities that separate me and you.” … Isaiah also says, “I came, and there was no one; I called, and there was none who listened.” He says these things, showing that we begin the desertion and become the causes of our destruction. For God not only desires not to leave or to punish us, but even when he punishes, he does it unwillingly. “I desire not,” he says, “the death of the sinner but that he should turn and live.” … Knowing this, let us do everything we can so as not to remove ourselves from God. Let us instead be concerned about the care of our souls and about our love toward one another.
In this instance the prophet Isaiah is not quoted as saying that “God” blinded the people.” However, it is likely that someone else did the blinding in order that the Jews should not convert and find healing. But, even though we should accept the supposition that God blinded them, it must be understood that God allowed them to suffer blinding at the hands of the devil as a result of their evil character.
