Rev 10:1

“"I saw another mighty angel coming down from heaven, clothed with a cloud; and a rainbow was upon his head, and his face was as it were the sun, and his feet as pillars of fire: and he had in his hand an open book: and he set his right foot upon the sea, and his left foot upon the earth." He signifies that that mighty angel who, he says, descended from heaven, clothed with a cloud, is our Lord, as we have above narrated. "His face was as it were the sun." That is, with respect to the resurrection. "Upon his head was a rainbow." He points to the judgment which is executed by Him, of shall be. "An open book." A revelation of works in the future judgment, or the Apocalypse which John received. "His feet," as we have said above, are the apostles. For that both things in sea and land are trodden under foot by Him, signifies that all things are placed under His feet. Moreover, he calls Him an angel, that is, a messenger, to wit, of the Father; for He is called the Messenger of great counsel. He says also that He cried with a loud voice. The great voice is to tell the words of the Omnipotent God of heaven to men, and to bear witness that after penitence is closed there will be no hope subsequently.”

“In this angel the person of our Savior is indicated. On his body he wears the church as though she were a cloud. For the church was constituted in the body of Christ and is often described in diverse manners. At times we read of her as a cloud, as a robe, as the sun, as the moon and as clothes white as snow. And even the saints are compared with clouds, as we read in the prophet Isaiah, "These are they who will fly as the clouds." To be sure, the cloud with which he is clothed is his body, which was conceived by the Holy Spirit. The "rainbow over his head" indicates the promise and the perseverance of his church. "His face was like the sun, and his feet as pillars of fire." There is here a great and marvelous plan, so that at the beginning of this book he might show the fire of the last persecution and afterward might indicate the future brightness of the saints as a fire. For at first he spoke of "his feet as refined in a furnace," and afterward he describes his face "as the shining in full strength." That he might show how great is the brightness of the church, he now mentions the face before the feet, which are refined, and afterward compares his feet with pillars of fire.”

“He sees the Lord Christ coming down from heaven dressed in a cloud, which is the church. Or, he is clothed by the cloud of his flesh, which is elsewhere said to be a new bride who descends from heaven, or as Daniel says, the Son of man has come on the clouds of the heavens. The arc above his head represents the promise of propitiation, which remains among those who are good, but it signifies also those who will be decorated with martyrdom before the advent of the Lord, as Abel and others.… And his face was as the sun, since the Lord Jesus Christ was made manifest through the glory of the resurrection, of which we read, "In the sun he has set his tabernacle," that is, where he is revealed so that he might no longer be hidden. For by his face is indicated the revelation of the present, which the prophet awaited and said, "Show your face, and we shall be saved." His feet are the apostles who were enflamed by the words of God and by the Holy Spirit and were sent out to preach. As it says, "Did not our hearts burn within us while he talked to us on the road and opened to us the Scriptures?" They are called "pillars" on account of the stability of the church, and of them the prophet said, "I have strengthened its pillars," and "How beautiful upon the mountains are the feet which announce and declare peace." Finally, the apostle said, "Who [Peter, James, John] were reputed to be pillars of the church."”

“And I saw another mighty angel coming down from heaven, clothed with a cloud. The Lord, the angel of great counsel, descended from heaven, clothed with the cloud of flesh. As Isaiah also says: Behold, the Lord is riding on a swift cloud and will come to Egypt (Isaiah XIX), and a rainbow was upon his head. Around the good, the promise of propitiation remains.”

“And his face was like the sun, etc. With the face of the Lord shining, that is, his knowledge manifested through the glory of the resurrection, his feet are prepared to evangelize and proclaim peace on the mountains (Romans X), illuminated by the fire of the Holy Spirit, and established like pillars. For James, Cephas, and John seemed to be pillars of the Church.”

“And I heard another mighty angel come down from heaven, clothed with a cloud. It is right for him to be called an angel, because he appeared to men as the new messenger of eternal life, about whom we read, angel of great counsel; and to be called strong, because it is demonstrated that he overcame the aerial powers when he died, whence this: the Lord mighty in battle. [Ps. 23:8] When he says another, it does not mean that he is actually talking about something different, but it is the habit of recapitulation: he saw another angel because he repeated another vision. The angel appeared clothed with a cloud because it was clothed in the flesh that the Lord was seen among men, and his descent from heaven was precisely his adoption of the flesh. And a rainbow was on his head. The head of Christ, as the apostle says, is the divinity itself. [1 Cor. 11:3] By the rainbow is symbolized the reconciliation of the world that was achieved by the plan of the Word incarnate; its mystery was explained earlier. Note also that, having described the last struggle, and passing over the seventh seal, with which both the end of the consummation and the Lord's coming are expected to take place, he comes back to the beginning of Christ's incarnation, which has just been spoken about, and describes his preaching. Once this narration is finished, he comes back to the things he had left aside for a while. Let us however remember that when he has brought this narration to its end, the end needs to be joined to the broken order; for the passage where it is said, in the following, The second woe is past, [Rev. 11:14] implicitly refers to the one where, in the end of the previous book, we spoke of the destruction of the wicked horses and Gentiles. Note also that he behaves in an unusual manner in this narration, and delimits both narrations not with one end, but with two, because he distinguishes the interrupted order and the recapitulation separately, as will become apparent a bit later. And his face was as the sun. The angel's face is Christ's incarnation, by means of which he became known to mortals, and concerning which the Psalmist says, Shew us thy face, and we shall be saved. [Ps. 79:4] This face is not compared to the sun because of its brightness, in which it is incomparably greater than the sun, but because, like the sun, it had a rising in being born, a setting in dying, and again a rising in being resurrected; whence Solomon, The sun riseth, and goeth down, etc. [Eccles. 1:5] The face may also be understood to mean the saints. And his foot as a pillar of fire. The angel's feet are the preachers, thanks to whom God's wisdom incarnate has, so to speak, walked through the whole world. It is fitting for them to be compared to a pillar and to fire because they both bear the Church's edifice, which is laid upon them, and, kindled by the Holy Spirit, set the hearts of their listeners on fire to the love of God by their preaching.”

“Moreover, John, the divine narrator in the present discourse, recounts the events that occurred when the sixth angel sounded his trumpet, which I have not yet fully explained all at once, since the fifth discourse is so long, I therefore did not reveal it in full. But what else does he write that has happened? Therefore, those who, while still alive, having heard or even seen the punishments inflicted upon the wrongdoers, did not repent, but remained wicked as previously stated, John says that I saw an angel descending from heaven, bringing images of punishments. He says that his vision and form were as follows: he was clothed with a cloud. The cloud symbolizes the eternal and invisible nature of the holy angels; for the cloud is a symbol of the unseen. The prophet, indicating the invisible nature of God, describes "clouds and thick darkness are round about him." (Ps. 97:2) And a rainbow was upon his head; as if the head and the foremost among the good angels were saying, it is brightness; for angels are beings of light. (2 Cor. 11:14) And his face is said to be like the sun; and this too is an appearance of pure brightness. But the rainbow is the brightness of a created nature, signifying virtue; therefore, the brightness of the rainbow is not uniform, but varied, indicating all the virtues of the angels. The sun, indeed, signifies their natural brilliance by a gleaming light. Therefore, it was surrounded by a rainbow, for virtues are around us; but its face resembled the sun, for in us all natural excellence is present in abundance. And his feet were like pillars of fire. The fire signifies the punishment that he came to bring upon the impious.”
