Rev 8:10

“The "great star" is the devil, of whom the Lord spoke in the Gospel, "I saw Satan fall from heaven as fire or lightning." It is possible that this passage also refers to ecclesiastical people, who living the spiritual life in the church, have become forgetful of themselves and like animals bend down to the things of the earth and fall from their positions of authority. We read what has been written of such persons: "Although he is in honor, he does not understand; he is compared to the senseless cattle and has become like them."”

“It speaks of men who have fallen from heaven as though from the church, that is, of those who have the public reputation of shining brightly with good merits. For that reason they are compared to stars and torches, as did the apostle Jude, who called them "stars of seduction," since they lead astray by a superficial splendor. And the Lord also compared such people with walls and "whitewashed tombs."”

“Some say that the bitterness revealed through the wormwood is symbolic of the torment that comes to those sinners being punished in Gehenna, who, on account of their number, are reasonably called "waters." But we think that these depictions signify the sufferings at the time, which has been shown. The star indicates either that these things come upon people from heaven, or it refers to the devil, of whom Isaiah says, "How has the Day Star, which rose in the morning, fallen from heaven." For, through pleasure he gives people a foul and bitter destruction to drink and through this allows punishing torments to come upon them, although not to everyone, but by the longsuffering of God to a third part.… It is necessary, therefore, that we examine ourselves lest we be judged. As the holy apostle says, "For if we judged ourselves, we should not be judged, but when we are judged by the Lord, we are chastened," and we receive the sufferings that come upon us with thanksgiving. For those who are concerned about sicknesses in the body bear patiently the cuts and cauteries of the physician, for they desire to be healed. Therefore, [we should examine ourselves] so that being spiritually healthy and bringing no wood to fuel the fire of Gehenna, we might not be condemned with the world but eternally rule with Christ, to whom be glory, honor and worship, together with the Father and the Holy Spirit forever. Amen.”

“And a great star fell from heaven, burning like a torch, etc. Heretics, whom Jude the apostle calls stars of seduction, falling from the height of the Church, try to infect the springs of divine Scriptures with the flame of their wickedness. They are not afraid to falsify not only the meaning but also the words frequently. They are worthy of the name "wormwood," whose slight mixing tends to embitter great sweetness.”

“And the third angel sounded the trumpet, and a great star fell from heaven, as it were a burning torch. The Devil is called a star, whether because of the rank he first had or because he transformeth himself into an angel of light; [2 Cor. 11:14] a great star because he was given precedence over all other angels, and a burning torch because of the fervor of his evilness. We should not understand this fall to be the one when he was first ejected from the heavenly abodes, but the one when he was excluded from among the elect by the angel sounding the trumpet, that is by the Church preaching; for heaven is the Church, which the Lord inhabits by presiding over it. And it fell on the third part of the rivers, and upon the fountains of waters, that is upon human nature, which flows by from its birth with the currents of carnal pleasures and thus runs down to death.”

“I believe this refers to the falling of the star, which, having angered God, made the waters bitter. Waters are metaphorically called humans, as stated by the prophet regarding "the sounds of many waters; the wonders of the sea's waves are marvelous," (Ps. 92:4) and again "the rivers lifted up their voices, saying, Lord, the rivers lifted up their voices; the rivers lifted up their waves." (Ps. 92:3) These things are to be understood as a form of allegorical speech. However, it must not be disregarded that such events and similar ones occur perceptibly.”
