Cyril of Alexandria : No one can deny that the prophet saw the Son in the glory of God the Father, as John said: "Isaiah said this because he saw his glory and spoke of him [Christ]." Look and see the great honor that is due to God, and see the authority he has over all creation. God is high and lifted up on a throne, crowned with the splendor of his reign.… In my view we should not think of the throne of God as lifted up in a physical way. That would be foolish and absurd. Rather, that the throne is said to be lifted up means that the reign of God transcends all things. That God is sitting refers to his immovability and that his blessings are everlasting and unchanging. — COMMENTARY ON Isaiah 1:4 Eusebius of Caesarea : The prophet had seen Christ and the glory of Christ in the vision in which he said, "I saw the Lord of hosts sitting upon a throne, high and lifted up," and what follows. — PROOF OF THE GOSPEL 9:16 Jerome : We have talked about standing; we have talked about walking; let us talk about sitting. Whenever God is represented as seated, the portrayal takes one of two forms: either he appears as the ruler or as the judge. If he is like a king, one sees him as Isaiah does: "I saw the Lord seated on a high and lofty throne." There he is presented as the sovereign king. — HOMILIES ON THE Psalms 14 (Psalms 81) Jerome : (Chapter 6, Verse 1) In the year when King Uzziah died, I saw the Lord sitting on a high and lofty throne. Isaiah prophesied under the reign of four kings over Judah and Jerusalem, as indicated in the introduction to the first vision: Uzziah, Jotham, Ahaz, and Hezekiah. After Uzziah died, under whom all the things we have mentioned above were spoken, his son Jotham succeeded him. Jotham reigned for sixteen years and did what was right in the sight of the Lord. He also built a high gate for the temple. When he saw this, Isaiah saw the Lord sitting on a high and lofty throne, to show the appearance of a ruler. And those things which were under him, filled the Temple, whether as Theodotius and Symmachus carried it over: And those things which were under his feet, filled the Temple. For which reason the Seventy interpreted. And the house was full of his glory. About thirty years ago, when I was in Constantinople, with the most eloquent man Gregory Nazianzen, then bishop of the same city, I recall having dictated a brief and sudden treatise on this vision, in order to test my little talent and to obey my friends' advice. Therefore, I send this little book to the reader, and pray that he may be satisfied with a brief explanation of this time. It tells the sacred story of Aziah, who claimed for himself an illicit priesthood and was struck with leprosy; and when he died, the Lord appeared in the Temple that he had defiled (2 Chronicles 26). From this, we understand that while we have a leprous king ruling within us, we cannot see the Lord reigning in His majesty, nor understand the mysteries of the Holy Trinity. And in Exodus, after Pharaoh, who oppressed Israel with mud and bricks, and later with straw, died, the people cried out to the Lord, who they could not cry out to while he was still alive. And when Phaltia son of Bananiah, a wicked ruler, died, Ezekiel fell on his face and with a loud voice cried out to the Lord. And it is beautifully said in the Hebrew: the Lord does not fill the Temple, whose heaven is his throne and the earth is his footstool; and as we read elsewhere: The Lord is in his holy Temple, the Lord's throne is in heaven (Psalms 11:5); but the things under his feet filled the Temple (Isaiah 66). But who is this Lord that is seen, as we learn more fully in the Gospel of John and in the Acts of the Apostles. Of whom John says: These things said Isaiah when he saw his glory and spoke of him (John 12:41), undoubtedly referring to Christ. Again, Paul in the Acts of the Apostles, where he speaks to the Jews in Rome, says: Well said the Holy Spirit through Isaiah the prophet to our fathers, saying: Go to this people, and say: Hearing you will hear and shall not understand, and seeing you will see and not perceive; for the heart of this people has grown dull, their ears are hard of hearing, and their eyes they have closed, lest they should see with their eyes and hear with their ears, lest they should understand with their heart and turn, so that I should heal them (Acts 28:26-27). However, the Son appeared in the form of one who reigns, and the Holy Spirit spoke because of the sharing of majesty and the unity of substance. Someone may ask, how can the Prophet say that he saw the Lord now, and not just the Lord, but the Lord of hosts, as he himself testifies in the following text; since the evangelist John said: No one has ever seen God (John 1:20). And God speaks to Moses: You cannot see my face, for no one can see me and live (Exodus 33:20). To this we will respond, not only regarding the divinity of the Father, but also of the Son and the Holy Spirit, because there is one nature in the Trinity, that is able to see with the eyes of the flesh; but with the eyes of the mind, as the Savior himself says: Blessed are the pure in heart, for they shall see God (Matthew 5:8). We read that Abraham saw the Lord in the form of a man, and that Jacob wrestled with him as a man, who was God. Therefore, that place itself was called Peniel, which means 'face of God': For I have seen the Lord face to face, and my soul has been saved (Genesis 32). Ezechiel also saw the Lord in the form of a man sitting upon Cherubim, from his loins downwards he was like fire, and the upper parts had the appearance of electricity. Therefore, the nature of God is not seen, but appears to humans as he chooses. — Commentary on Isaiah John Chrysostom : It is obvious from the very words of Isaiah that he saw God because of God's condescension. He said, "I saw the Lord sitting on a high and lofty throne." But God is not sitting down. Beings with bodies sit. Isaiah also said, "on a throne." But God is not encompassed by a throne, because divinity cannot be contained within boundaries. That said, the seraphim could not endure the condescension of God although they were nearby.… He said, "And the seraphim stood around him," because he wanted to make it clear that although the seraphim are closer to the essence of God than human beings are, they cannot look upon his essence simply because they are closer to it. He is not referring to place in a localized sense. When he speaks of nearness, he is demonstrating that the seraphim are closer to God than we human beings are. — AGAINST THE ANOMOEANS 3:16 John Chrysostom : Why does God appear to be sitting on a throne with seraphim, when God does not sit? He is accommodating himself to the ways of human beings. — COMMENTARY ON Isaiah 6:1.78-81 Theodoret of Cyrus : 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. — COMMENTARY ON Isaiah 6:1 Theodoret of Cyrus : 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. — COMMENTARY ON Isaiah 6:1
