On Isaiah

20 of 208
  1. Isaiah 1:4
    When Isaiah calls them “evil seed,” he does not mean to insult the ancestors of those to whom he was speaking. Rather he was denouncing their own wickedness, just as John the Baptist called the Jewish leaders “a brood of vipers” and the Lord called them “an evil and adulterous generation.” They were called these things because they did not preserve the virtuous life of those who went before them.

  2. Isaiah 1:5
    Isaiah calls the kings and the leaders the heads and the priests and teachers the heart. For what the heart is to the body, the priests and teachers are for the people, and what the head is for the body, the kings and leaders are for their subjects.

  3. Isaiah 2:2
    [Isaiah] announces the wonderful and widespread demonstration of piety everywhere: idolatry will be destroyed, while the house of God will receive its due sign of universal respect.… After our Savior’s appearing, idolatry will be shown and the beauty of truth will be unveiled. In this we will see the fulfillment of this announcement. Furthermore, by “last days” he means that time following incarnation.

  4. Isaiah 2:3
    I am amazed at the persistence of some to interpret this passage in such a way as to conclude that this is a prediction of the return from Babylonian captivity. Which nations rushed to the temple after its rebuilding? What law was given from there? God gave the ancient law on Sinai, not Zion. Clearly Isaiah is referring to the New Testament, where the law was first given to the apostles and then delivered to all peoples by them. He announces that in addition to the law, the word would come from Zion. The term word is a title given to the message of the gospel. The blessed Luke says, “Those who were from the beginning eyewitnesses and ministers of the word delivered them to us.” He is not talking about God the Word but the message of the divine word. Zion is not where God the Word was from but where he taught the truth.

  5. Isaiah 3:12
    Those who are zealous in the service of God, however, do not get a reward of praise, nor indeed do those who are concerned about the laws of God look for this return. For praise is often known to injure many, since it makes them less attuned and slows their pace. If a person thinks he has reached the goal of his endeavor—and praise gives him to understand that he has—he stops his race and victory eludes him. This was revealed by the God of the universe, speaking through the prophet: “My people, they that call you blessed, the same deceive you and destroy the way of your steps.” For praise slackens the intensity of their zeal and prevents them from reaching the goal.

    ON DIVINE PROVIDENCE 9:9

  6. Isaiah 6:1
    Isaiah has revealed the Father’s existence but not his essence (WHICH CANNOT BE SEEN). In other places God reveals himself in ways that also demonstrate that no one has seen his essence. Abraham saw him in one way, Moses in another, Micah saw him in yet another way, which was different from the way Daniel saw him. Ezekiel saw God in yet another way. God’s essence, however, does not have many different forms, because God is incorporeal, indivisible, simple, invisible and inaccessible.

  7. Isaiah 6:1
    By speaking of Uzziah’s death, the prophet informs us that it was Uzziah’s sin that had brought an end to prophetic activity. At the beginning of his reign Uzziah had God’s favor and was victorious over the Allophyles [foreigners]and other neighboring enemies. But he became blinded by pride because of his victory. His pride caused him to usurp the honor of the priesthood. He took it on himself to trespass into the sanctuary of the temple and offer incense, though even the priests were not allowed to do this, as only the high priest had the right to enter the Holy of Holies. Azarias and other priests tried to stop him from doing this, but he ignored their warning.… It was not until after the death of the king that God granted this vision to the prophet, who had angered God by not identifying the culpability of the king.

  8. Isaiah 6:3
    Because the seraphim use the title Lord singularly in this song, but repeat “holy” three times (in reference to the Trinity), we know they are referring to the one essence of Deity. The praise “holy, holy, holy” properly indicates the Trinity, and the appellation “Lord of Hosts” indicates the oneness of the divine essence. Furthermore, the seraphim, in their song, praise the eternal essence for having filled both heaven and the entire earth with his glory. This happened through the incarnation of our God and Savior; because after the appearing of the Master, the nations received the illuminating ray of divine knowledge.

  9. Isaiah 9:6
    But the prophet who predicted the Emmanuel has written of him a little further on that “unto us a child is born, unto us a son is given; and the government shall be upon his shoulders; and his name is called angel of great counsel, wonderful, counselor, mighty God, powerful, Prince of peace, Father of the age to come.” Now if the baby born of the virgin is styled “Mighty God,” then it is only with reason that the mother is called “mother of God.” For the mother shares the honor of her offspring, and the Virgin is both mother of the Lord Christ as man and again is his servant as Lord and Creator and God.

    LETTER 152

  10. Isaiah 10:14
    Behold, then, how the Maker of the universe has always shown a loving care for humanity, not merely for the race of the descendants of Abraham but for all the descendants of Adam; through one tribe he has led all tribes to a knowledge of himself. He used them for this purpose both when they were religious and when they were paying the penalty for their sins. For instance, Nebuchadnezzar, the arrogant tyrant, who raised up the golden image and called on all to adore it, said, “I will gather in my hand the whole earth as a nest, as eggs that lie abandoned will I gather it.”

    ON DIVINE PROVIDENCE 10:54

  11. Isaiah 11:10-11
    Now Jesse was the father of David, and the promise with an oath was made to David. The prophet would not have spoken of the Lord Christ as a rod growing out of Jesse if he had only known him as God.

  12. Isaiah 19:1
    Therefore all the human qualities of the Lord Christ, hunger, I mean, and thirst and weariness, sleep, fear, sweat, prayer, and ignorance, and the like, we affirm to belong to our nature which God the Word assumed and united to himself in effecting our salvation. But the restitution of motion to the maimed, the resurrection of the dead, the supply of loaves and all the other miracles we believe to be works of the divine power. In this sense I say that the same Lord Christ both suffers and destroys suffering; suffers, that is, as touching the visible, and destroys suffering as touching the ineffably indwelling Godhead. This is proved beyond question by the narrative of the holy Evangelists, from whom we learn that when lying in a manger and wrapped in swaddling clothes, he was announced by a star, worshiped by magi and hymned by angels. Thus we reverently discern that the swaddling bands and the lack of a bed and all the poverty belonged to the manhood; while the journey of the magi and the guiding of the star and the company of the angels proclaim the Godhead of the unseen. In like m…

In like manner he makes his escape into Egypt and avoids the fury of Herod by flight, for he was man; but as the prophet says, “He shakes the idols of Egypt,” for he was by nature God.

    LETTER 151

  13. Isaiah 23:4
    To convince you of this, return again to the sea, and observe its depths, its extent, its division into bays, its shores, its port, the islands in its midst, the kinds of fishes in it and their species, shapes, variety and fondness for the shore.…Since journeying by land is fraught with difficulty and the satisfaction of all our needs on such journeys is not only difficult but impossible, the surface of the sea is there to take vessels, small and large, and to provide much necessary cargo for those in short supply. A single frigate can be seen taking as much as many thousand beasts. To ease the burden for seafarers the Creator made islands as ports in which they could call, rest, buy their needs and then set sail again for their destination. “Be ashamed” then “at this multitude of blessings, said the sea.” For the words of the prophet apply more to you than to Sidon. For Sidon, ignoring the Creator, divided the divinity into many gods, mutilated the monotheistic form of worship and extended it to nonexistent deities, not indeed denying providence but ascribing it also to these false…
    To convince you of this, return again to the sea, and observe its depths, its extent, its division into bays, its shores, its port, the islands in its midst, the kinds of fishes in it and their species, shapes, variety and fondness for the shore.…Since journeying by land is fraught with difficulty and the satisfaction of all our needs on such journeys is not only difficult but impossible, the surface of the sea is there to take vessels, small and large, and to provide much necessary cargo for those in short supply.

    For the words of the prophet apply more to you than to Sidon. For Sidon, ignoring the Creator, divided the divinity into many gods, mutilated the monotheistic form of worship and extended it to nonexistent deities, not indeed denying providence but ascribing it also to these false gods. For it would not offer sacrifice to these false gods unless it had fully persuaded itself that they provide assistance and avert disaster. But you who have been delivered from the error of polytheism and agree that all visible things are created; you, who adore their Creator, banish him from his creatures, set him completely outside his creation, assert that such an ordered universe is without a pilot and is borne about aimlessly like a ship without ballast. Be ashamed, then, at the blessings received from the sea, from the earth, from the air, from the sun and the sky that affords a roof over our heads. Respect the tribute you receive from creation.

  14. Isaiah 36:1-2
    The book of 2 Kings also speaks of this event. Isaiah has included it to his prophecy in order to show that his prophecy is true. Previously the prophet has made announcements concerning Babylon, Tyre, Egypt and other nations, but he is mostly concerned with the incarnation of our Savior, the unbelief and resultant judgment of Israel, and the call and salvation of the Gentiles. He has also announced Assyria’s attack and their ultimate destruction. It follows that he would include this event here to demonstrate that his prophecies are true. By showing that the announcement related to Sennacherib is true, he can show that all his other prophecies will be fulfilled in the same way.

  15. Isaiah 40:2
    The God of the universe has left the king aside to invite the priests to give courage back to Jerusalem, as if the chastisement with which it had been threatened had already occurred. This is made clear in the passage to follow: “Comfort [Jerusalem], for its humiliation is accomplished.” The words of the threat have received a perfect accomplishment. “[Its] sin is put away: for it has received of the Lord’s hand double the amount of its sins.” It is worthwhile to admire the kindness of the Master at this point: because he is good and his compassion is unfathomable, and although he inflicted a punishment less than equal to the sin, he says, by reason of great benevolence, that this lesser punishment is double the amount of the sin. Now that the chastisement was less than the sin, the same prophet has cried in testimony: “Your chastening was to us with small affliction.” Nevertheless, because he tempers his justice with infinite mercy, the lesson that the victims of the chastisement call small, the judge has called double [the amount of the sin]. Then he teaches the comforters the mean…

Then he teaches the comforters the means of comfort.

  16. Isaiah 40:3
    The true consolation, the genuine comfort and the real deliverance from the iniquities of humankind is the incarnation of our God and Savior. Now the first who acted as herald of this event was the inspired John the Baptist. Accordingly, the prophetic text proclaims the realities that relate to him in advance, for that is what the three blessed Evangelists have taught us and that the most divine Mark has even made the prologue of his work. As for the inspired John, whom the Pharisees asked whether he himself was the Christ, he declared on his part: “I am ‘the voice of one crying in the wilderness, Make straight the way of the Lord’ ” as the prophet Isaiah said; I am not God the Word but a voice, for it is as a herald that I am announcing God the Word, who is incarnate. Moreover, he refers to the Gentiles as the “untrodden [land]” because they have not yet received the prophetic stamp.

  17. Isaiah 40:4
    He has clearly shown by these terms the facility of the evangelical proclamation: thanks to this facility, in a short time it filled the whole world. One should understand by “filled valleys” and “mountains and hills brought low” that literally it relates to a way that is level and cleared of all obstacles, but in a figurative sense, the souls of the unbelievers are the valleys, those who are lying in some way at the bottom of a pit and who do not have the intelligence to turn toward the heavens, while the mountains and the hills are the demons who are worshiped on the mountains and on the hills, whose deceit has been ended by the incarnation of our Savior.

  18. Isaiah 40:5
    The one who has made these declarations, he says, is incapable of deceit. As for me, I am greatly astonished at those who think that the prophet has made these prophecies on the subject of the return from Babylon; for they should have considered that the prophetic text has clearly proclaimed in advance that the salvation of God would be evident for all people, whereas this return [from exile] was not evident for all, while the cross of the Savior and the sufferings of the Master have reached even to the ends of the earth.

  19. Isaiah 40:9
    It is the chorus of the apostles that the prophetic text raises here. It is precisely for this reason that after expressing this exhortation in the singular the text shifts into the plural and says, “Lift up [the voice], do not fear.” In the same way, in his turn, Christ our Master said to the apostles, “Do not fear those who kill the body but cannot kill the soul.” And again, after bringing them out from the prison, he bade them to proclaim quite freely the words of this life. Moreover, he calls “mountain” the summit of the knowledge of God.

  20. Isaiah 40:10
    These words are a glimpse of the second coming of the Savior. It is then that he will give the laborers their reward. “He will reward each according to his works,” according to the word of the apostle. “For the Day,” he says, “will declare it, because it will be revealed by fire; and the fire will test each one’s work, of what sort it is.” This is the proclamation that the Lord has ordained to the holy apostles to make in their turn. “Go,” he has said, “to the lost sheep of the house of Israel. And as you go, preach, saying, ‘The kingdom of heaven is at hand.’ ” One can therefore see that the oracles of the prophet are thus in agreement with the words of the Gospel.
