17:15-18 God so ruled the hearts of these kings, by his power over them, and by his providence, that they did those things, without intending it, which he purposed and foretold. They shall see their folly, and how they have been bewitched and enslaved by the harlot, and be made instruments in her destruction. She was that great city which reigned over the kings of the earth, when John had this vision; and every one knows Rome to be that city. Believers will be received to the glory of the Lord, when wicked men will be destroyed in a most awful manner; their joining together in sin, will be turned to hatred and rage, and they will eagerly assist in tormenting each other. But the Lord's portion is his people; his counsel shall stand, and he will do all his pleasure, to his glory, and the happiness of all his servants.
15. (Re 17:1; Isa 8:7.) An impious parody of Jehovah who "sitteth upon the flood" [Alford]. Also, contrast the "many waters" Re 19:6, "Alleluia."
peoples, and multitudes, and nations, and tongues—The "peoples," &c., here mark the universality of the spiritual fornication of the Church. The "tongues" remind us of the original Babel, the confusion of tongues, the beginning of Babylon, and the first commencement of idolatrous apostasy after the flood, as the tower was doubtless dedicated to the deified heavens. Thus, Babylon is the appropriate name of the harlot. The Pope, as the chief representative of the harlot, claims a double supremacy over all peoples, typified by the "two swords" according to the interpretation of Boniface VIII in the Bull, "Unam Sanctam," and represented by the two keys: spiritual as the universal bishop, whence he is crowned with the miter; and temporal, whence he is also crowned with the tiara in token of his imperial supremacy. Contrast with the Pope's diadems the "many diadems" of Him who alone has claim to, and shall exercise when He shall come, the twofold dominion (Re 19:12).
