Ambrose of Milan : The angels, too, were in doubt when Christ arose; the powers of heaven were in doubt when they saw that flesh was ascending into heaven. Then they said, "Who is this King of glory?" And yet some said, "Lift up your heads, O gates! And be lifted up, O ancient doors! That the King of glory may come in." In Isaiah, too, we find that the powers of heaven doubted. — On the Mysteries 7:36 Cyril of Alexandria : For he appeared to the powers above not only in the form in which he came for us, that is, as a human, but also showing the signs of his passion. Thus, we say that after his resurrection from the dead the marks of the nails and the other things of his wounds were marked on the holy flesh.… So that the angels asking each other might say, "Who is this?" He considers and replies to them, "I speak justice and the judgment of salvation." He calls "justice" the divine and good news-bearing message or every just word that the Lord speaks. And the judgment of salvation refers to the judgment we receive. He indicated the world also to Satan, who was accusing it, and he saved those burdened by terrible greed. And he expelled the rebel and foreign usurper from among them, saying, "Now is the judgment of this world." — COMMENTARY ON Isaiah 5:5.63:1-7 Cyril of Alexandria : The only-begotten Word of God ascended in the heavens with his flesh united to him, and this was a new sight in the heavens. The multitude of holy angels was astounded seeing the king of glory and the Lord of hosts in a form similar to ours. And they said, "Who is this that comes from Edom [that is, from earth], in crimsoned garments, from Bosor." But "Bosor" is to be interpreted as "flesh" or "anguish and affliction." — LETTER 41:17 Ishodad of Merv : "Who is this that comes from Edom?" It seems that the prophet sees God under the aspect of a warrior who marches at the head of his people, and, after destroying the Edomites, has come back and arrives; and the prophet asks who is this that comes from Edom and Bozrah, their royal cities. — COMMENTARY ON Isaiah 63:1 Jerome : Similarly, in Isaiah, "who is this that comes from Edom, in radiant garments?" Notice what the angels do; they proclaim his beauty but are silent about his essence. — HOMILIES ON THE PSALMS, ALTERNATE SERIES 69 (Psalms 91) Jerome : (Chapter 63, Verse 1) Who is this that comes from Edom, with dyed garments from Bozrah? This one is glorious in his apparel, marching in the greatness of his strength. (Chapter 70) Who is this that comes from Edom, with dyed garments from Bozrah? This one is beautiful in his attire, strong and mighty. From the place where it is said in the Septuagint: "Arise, shine, Jerusalem, for your light has come, and the glory of the Lord has risen upon you" (Chapter 60, Verse 1), to the present chapter where it says: Who is this that comes from Edom, with dyed garments from Bosrah? Many of our own refer to the end of the world, in which, whether in a physical or spiritual sense (for there are various opinions of many), they strive to fulfill. But we, because we have also read earlier in this same chapter: The Spirit of the Lord is upon me, because he has anointed me to bring glad tidings to the poor: he has sent me to proclaim liberty to captives, and recovery of sight to the blind, to let the oppressed go free (Luke 4:18). And now it is said of the same, that after his passion he ascended to the Father in a bloody manner, we are compelled by necessity to understand all that is said in reference to the first coming of the Savior. For it cannot happen, as many of our people strive to do, that things which are connected in the works should be varied in time; nor do we deny that it requires great effort to unite all these things to be fulfilled in a spiritual way in the consummation, so that we may teach that they have already been accomplished in Christ, both according to the flesh and according to the spirit. Therefore, since the Savior of the daughter of Zion has come, whose reward is with Him, and His work before Him; and the righteous One has gone forth as brightness, and the Savior has been kindled as a lamp, and the bridegroom has rejoiced over his bride the Church, indeed his God has exulted over her, who is Himself both bridegroom and Lord: therefore, according to the assumption of the flesh and the passion of the cross, it is said to Him: Let Your foot be dipped in blood (Ps. 68:24). And under the name Judah in Genesis it is prophesied: Judah, your brothers shall praise you; your hand shall be on the necks of your enemies. Your father's sons shall bow down to you. Judah, you have ascended as a lion's cub; you lie down and rest like a lion, and like a lioness; who shall rouse you? And again: He binds his foal to the vine, and his donkey's colt to the choice vine; he washes his garments in wine, and his robe in the blood of grapes. This is the one whom the angelic powers, seeing him ascend to the Father, command the other angels, and they hear from them: Lift up your gates, O princes, and be lifted up, eternal gates, that the King of glory may enter. Who is this King of glory? The Lord, strong and mighty, the Lord, mighty in battle (Psalms 24:7-8). And again: The Lord of hosts, he is the King of glory (ibid., 10). We have said this as a prelude, so that we may show that this chapter agrees with other testimonies as well. And in the Song of Songs it is said: My beloved is ruddy and white (Song of Songs 5:10); ruddy in passion; white in resurrection. Therefore, the angels ask, terrified by the novelty of the matter (for the mystery of the passion and resurrection of Christ, according to the apostle Paul (1 Corinthians 2), had been unknown to all previous generations). Who is this coming from the land of Edom, with garments stained crimson? Indeed, Edom is expressed in our language as both earthly and bloody. With dyed garments from Bozrah? Many, in their pious error, think that it refers to the flesh of the Lord: that is, Basar (בשר), which word, if it signified flesh, would be written with the middle letter Sin, but is now written with the letter Sade, and is interpreted as firm and fortified: which we either understand as referring to Jerusalem (Psalms 59:11), which was surrounded by very strong walls, in which the Lord suffered; or to hell, of which it is written in Psalms 59:11 and Psalms 107:10: 'Who will bring me into the fortified city?' In which the souls of the dead are closed, and they are surrounded by the strongest custodies. It should also be known that according to the history of Bosra, it is not in Edom but in Moab. It follows: So beautiful in his robe, walking in the multitude of his strength. Of which the forty-fourth psalm also sings: Beautiful in beauty above the sons of men. Gird thy sword upon thy thigh, O most mighty. With thy comeliness and thy beauty, proceed prosperously and reign (Psalms 44, 3-5). Why they translated the Septuagint, violence with strength. A wise reader will inquire into the meaning. I am the one who speaks of justice, and I am a champion for salvation. LXX: I am the one who speaks of justice, and the judgment of salvation. The Lord replied to the questioning Angels: Do you ask who I am, who will ascend to the bloody heavens, and the blood with which I am covered will not give me ugliness, but beauty? I am the one to whom the Father has entrusted all judgment (John 5). Of whom the Psalmist also said: Grant your judgment to the king, O God, and your justice to the king's son (Psalms 72:1). I speak justice: to give evil to the wicked, and to repay good to the righteous; to come and fight against opposing powers, and to preach freedom to the captives, and to release those in prison, so that both adversaries may feel punishment and captives may experience freedom. — Commentary on Isaiah Tertullian : He likewise, when mentioning the cup and making the New Testament to be sealed "in his blood," affirms the reality of Christ's body. For no blood can belong to a body that is not a body of flesh. If any sort of body were presented to our view, which is not one of flesh, not being fleshly, it would not possess blood. In order, however, that you might discover how anciently wine is used as a figure for blood, turn to Isaiah, who asks, "Who is this that comes from Edom, from Bosor with garments dyed in red, so glorious in his apparel, in the greatness of his might? Why are your garments red, and your clothing as his who comes from the treading of the full winepress?" The prophetic Spirit contemplates the Lord as if he were already on his way to his passion, clad in his fleshly nature; and as he was to suffer therein, he represents the bleeding condition of his flesh under the metaphor of garments dyed in red, as if reddened in the treading and crushing process of the winepress, from which the laborers descend reddened with the wine juice, like men stained in blood. — AGAINST MARCION 4.40 Theodoret of Cyrus : They call the red land "Edom," and "Bosor" to the flesh; they were amazed at the ineffable beauty of the one wrapped in earthly and fleshly apparel, such as to drive those who looked to love. The blessed David is mindful of this beauty: "Fair and beautiful among the sons of humankind." That Edom means flame-colored is affirmed in the Song of Songs by the bride, who cries, "My beloved is red and white." Christ's nature is twofold. Therefore, white means the inaccessible light of divinity, red the human appearance. — COMMENTARY ON Isaiah 19:63.1-6
