Revelation 15:6

“And the seven angels came out of the temple, etc.] By which it appears, that they are such who are of, or belong to the church of Christ; and are either ministers, or members of churches, who will be the executioners of God's wrath upon the beast, and his followers; some copies, and the Complutensian edition, read, “out of heaven”: having the seven plagues; that is, they were appointed to inflict them, and were preparing and furnishing for it, and quickly had orders to do it: clothed in pure and white linen; in which habit angels have been used to appear, as at our Lord's resurrection and ascension, and is by some thought to be expressive of the purity and holiness of angels; but rather…”

“having--So B reads. But A and C, read "who have": not that they had them yet (compare Rev 15:7), but they are by anticipation described according to their office. linen--So B reads. But A, C, and Vulgate, "a stone." On the principle that the harder reading is the one least likely to be an interpolation, we should read, "a stone pure ('and' is omitted in A, B, C, and ANDREAS), brilliant" (so the Greek): probably the diamond.

“And the seven angels - See the notes on Revelation 15:1. Came out of the temple - Were seen to come from the temple; that is, from the immediate presence of God. Having the seven plagues - See the notes on Revelation 15:1. Each one entrusted with a single “plague” to be executed upon the earth. The meaning here is, that they were designated or appointed to execute those plagues in judgments. The symbols of their office - the golden vials - were given to them afterward, Revelation 15:7. Clothed in pure and white linen - The emblem of holiness - the common representation in regard to the heavenly inhabitants. See the notes on Revelation 3:4; Revelation 7:13. Compare Matthew 17:2; Luke 9:29;…”

“And the seven angels came out of the temple - As having received their instructions from the oracle of God himself. St. John saw them in heaven, Rev 15:1, before they went into the temple. They appeared in habits like those the high priest wore when he went into the most holy place to consult the oracle. In this was the visible testimony of God's presence. Clothed in pure white linen - Linen is the habit of service and attendance. Pure - unspotted, unsullied. White - Or bright and shining, which implies much more than bare innocence. And having their breasts girt with golden girdles - In token of their high dignity and glorious rest. Revelation 15:7”
