And upon her forehead... — It was usual with harlots to wear their name on the forehead; but the name here is more than a name. Like the name impressed upon the foreheads of the saints, it is “the expression of her nature” —
“MYSTERY, BABYLON THE GREAT, THE MOTHER OF THE HARLOTS AND OF THE ABOMINATIONS OF THE EARTH.”
The word “mystery” is, perhaps, part of the name; it is, at any rate, a prefix which tells us that the name is not literal, but symbolical. Something lies behind, which will be made manifest in due time. (Comp. 2 Thessalonians 2:7.) She is mother of harlots. Others, in smaller spheres, will follow her example; but she is the origin and type of all.
(6) And I saw the woman drunken with the blood of the saints. — It is said later (Revelation 18:24) that in her was found the blood of prophets, and saints, and of all that have been slain upon the earth. The cruel spirit of persecution marked old Pagan Rome. She was drunk with their blood. It is not literally true that “all the blood shed on the earth” would be found in Rome, either Pagan or Papal; but it is spiritually true. Just as all the blood from righteous Abel to Zacharias was required of Jerusalem, so also of Babylon; for the spirit is the same spirit of hatred of holiness and love of worldliness. To slay one is to slay all, as to be guilty in one point of the Law is to be guilty of all; for it is not to mere acts, but also to the spirit and drift of men’s conduct, that the Scriptures look. It is the Babylon spirit, whether dominant in Rome or in London, that kills the good. Wherever the spirit of worldliness (in its widest sense) is to be found, there is the spirit at enmity with God and good, and there is the Babylon which has slain the saints.
And when I saw her, I wondered... — Rather, And I wondered when I saw her with great wonder (not “admiration” in our modern sense). Why did St. John wonder? Was it at the splendour or the blasphemous names? Hardly these; for he was familiar with the former in descriptions of Babylon given by the prophets, and with the latter from his own vision in Revelation 13. The wonder probably rose from the strange alliance of the woman with the wild beast. It was not wonderful to see the vision of a wild beast or monster dealing out death and slaughter, but to see a woman allied with the monster and drunken with the blood of the holy provoked astonishment. The woman, too, was a harlot. The prophets had spoken of Israel and Judah as harlots, where they had allied themselves with the world and its dark idolatries (comp. Isaiah 1:21; Jeremiah 2:20; Ezekiel 16:15; Hosea 2:5). Did he read in the form of the vision the hint that in the lapse of years the Church of Christ, like Israel of old, might fall from her high calling and become the ally of the world-power? The hint of it slumbered in the vision.
(7) And the angel said unto me, Wherefore didst thou marvel? — Better, Wherefore didst thou wonder? The angel explains the mystery or hidden meaning. In doing so he identifies the wild beast which carries the woman with the wild beast of Revelation 13. In that chapter the wild beast was seen wounded to death; the same thought is expressed in this chapter. The wild beast was and is not It has received its death wound: the dying and risen Lord has given the death-blow to the world-power, as He has cast down Satan (Revelation 12:9), put limits to his power (Revelation 20:2), and destroyed him that had the power of death (Hebrews 2:14). In the victory of Christ the wild beast that was (i.e., that had in successive ages been seen in the great world-powers) is slain, or, as the angel expresses it, is not. But though he is not, though he is to be reckoned as doomed, yet he will show signs of vitality: he will rise into temporary power. He shall come up out of the abyss. But the march of his power is only a march to the grave. He goes to destruction. Yet this transient revival and apparent recovery from its death-wound will be viewed (as was said in Revelation 13:3 : “all the earth wondered after the wild beast”) as a marvel by those whose [??] are not heaven-taught, and whose minds are set upon earthly things. They that dwell upon the earth shall wonder, whose name is not written on the book of life from the foundation of the world, seeing the wild beast that he was, and is not, and shall be present (i.e., shall come again).
