Matthew Henry Commentary Revelation 15:5-8

"And after these things I saw, and the temple of the tabernacle of the testimony in heaven was opened: and there came out from the temple the seven angels that had the seven plagues, arrayed with [precious] stone, pure [and] bright, and girt about their breasts with golden girdles. And one of the four living creatures gave unto the seven angels seven golden bowls full of the wrath of God, who liveth for ever and ever. And the temple was filled with smoke from the glory of God, and from his power; and none was able to enter into the temple, till the seven plagues of the seven angels should be finished." — Revelation 15:5-8 (ASV)

In the judgments God executes upon antichrist and his followers, he fulfills the prophecies and promises of his word. These angels are prepared for their work, clothed with pure and white linen, their breasts girded with golden girdles, representing the holiness, and righteousness, and excellence of these dealings with people. They are ministers of Divine justice and do everything in a pure and holy manner.

They were armed with the wrath of God against his enemies. Even the lowliest creature, when armed with the anger of God, will be too strong for anyone in the world. The angels received the vials from one of the four living creatures, one of the ministers of the true church, in answer to the prayers of the ministers and people of God. Antichrist could not be destroyed without a great shock to all the world, and even the people of God would be in trouble and confusion while the great work was being done.

The greatest deliverances of the church are brought about by awesome and astonishing steps of Providence, and the happy state of the true church will not begin until obstinate enemies are destroyed and lukewarm or formal Christians are purified. Then, when whatever is against Scripture has been purged away, the whole church shall be spiritual; and the whole, being brought to purity, unity, and spirituality, shall be firmly established.
