8:8 {6} And the second angel sounded, and as it were a great mountain burning with fire was cast into the sea: and the third part of the sea became blood;
(6) The second execution on the sea, in this verse and all things that are in Re 8:9.
8:8,9 THE SECOND TRUMPET.
And the second angel sounded. Then the scene changes.
And as it were a great mountain burning with fire was cast into the sea. Now a great burning mountain is cast into the sea. The sea is the theater of destruction.
And the third part of the sea became blood. Again there is fire and blood indicating carnage and destruction. In the first judgment the third part of the earth suffers (Re 8:7); but now a third part of the sea. The symbols imply that some mighty volcanic power shall be turned upon the sea, and make it a scene of awful warfare and destruction.
8:8 And the second angel sounded, and as it were a great mountain burning with fire was cast into the sea - By the sea, particularly as it is here opposed to the earth, we may understand the west, or Europe; and chiefly the middle parts of it, the vast Roman empire. A mountain here seems to signify a great force and multitude of people. Jer 51:25; so this may point at the irruption of the barbarous nations into the Roman empire. The warlike Goths broke in upon it about the year 250: and from that time the irruption of one nation after another never ceased till the very form of the Roman empire, and all but the name, was lost. The fire may mean the fire of war, and the rage of those savage nations. And the third part of the sea became blood - This need not imply, that just a third part of the Romans was slain; but it is certain an inconceivable deal of blood was shed in all these invasions.
8:7-13 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.
