Complete Commentary on the Whole Bible, by Matthew Henry, at sacred-texts.com
(Rev 8:1, Rev 8:2) The seventh seal is opened and seven angels appear with seven trumpets, ready to proclaim the purposes of God.
(Rev 8:3-5) Another angel casts fire on the earth, which produces terrible storms of vengeance.
(Rev 8:6) The seven angels prepare to sound their trumpets.
(Rev 8:7-12) Four sound them.
(Rev 8:13) Another angel denounces greater woes to come.
The seventh seal is opened. There was profound silence in heaven for a space; all was quiet in the church, for whenever the church on earth cries through oppression, that cry reaches up to heaven; or it is a silence of expectation. Trumpets were given to the angels, who were to sound them. The Lord Jesus is the High Priest of the church, having a golden censer, and much incense, fulness of merit in his own glorious person. Would that men studied to know the fulness that is in Christ, and endeavoured to be acquainted with his excellency. Would that they were truly persuaded that Christ has such an office as that of Intercessor, which he now performs with deep sympathy. No prayers, thus recommended, was ever denied hearing and acceptance. These prayers, thus accepted in heaven, produced great changes upon earth. The Christian worship and religion, pure and heavenly in its origin and nature, when sent down to earth and conflicting with the passions and worldly projects of sinful men, produced remarkable tumults, here set forth in prophetical language, as our Lord himself declared, Luk 12:49.
The first angel sounded the first trumpet, and there followed hail and fire mingled with blood. A storm of heresies, a mixture of dreadful errors falling on the church, or a tempest of destruction. The second angel sounded, and a great mountain, burning with fire, was cast into the sea; and the third part of the sea became blood. By this mountain some understand leaders of the persecutions; others, Rome sacked by the Goths and Vandals, with great slaughter and cruelty. The third angel sounded, and there fell a star from heaven. Some take this to be an eminent governor; others take it to be some person in power who corrupted the churches of Christ. The doctrines of the gospel, the springs of spiritual life, comfort, and vigour, to the souls of men, are corrupted and made bitter by the mixture of dangerous errors, so that the souls of men find ruin where they sought refreshment. The fourth angel sounded, and darkness fell upon the great lights of heaven, that give light to the world, the sun, and the moon, and the stars. The guides and governors are placed higher than the people, and are to dispense light, and kind influences to them. Where the gospel comes to a people, and has not proper effects on their hearts and lives, it is followed with dreadful judgments. God gives alarm by the written word, by ministers, by men's own consciences, and by the signs of the times; so that if people are surprised, it is their own fault. The anger of God makes all comforts bitter, and even life itself burdensome. But God, in this world, sets bounds to the most terrible judgments. Corruption of doctrine and worship in the church are great judgments, and also are the usual causes and tokens of other judgments coming on a people. Before the other three trumpets were sounded, there was solemn warning how terrible the calamities would be that should follow. If lesser judgments do not take effect the church and the world must expect greater; and when God comes to punish the world, the inhabitants shall tremble before him. Let sinners take warning to flee from the wrath to come; let believers learn to value and to be thankful for their privileges; and let them patiently continue in well doing.
