181 After this I saw another angel coming down from heaven, having great authority, and the earth was made bright with his glory. 2 And he called out with a mighty voice, "Fallen, fallen is Babylon the great! She has become a dwelling place for demons, a haunt for every unclean spirit, a haunt for every unclean bird, a haunt for every unclean and detestable beast. 3 For all nations have drunk[1] the wine of the passion of her sexual immorality, and the kings of the earth have committed immorality with her, and the merchants of the earth have grown rich from the power of her luxurious living." 4 Then I heard another voice from heaven saying, "Come out of her, my people, lest you take part in her sins, lest you share in her plagues; 5 for her sins are heaped high as heaven, and God has remembered her iniquities. 6 Pay her back as she herself has paid back others, and repay her double for her deeds; mix a double portion for her in the cup she mixed. 7 As she glorified herself and lived in luxury, so give her a like measure of torment and mourning, since in her heart she says, 'I sit as a queen, I am no widow, and mourning I shall never see.' 8 For this reason her plagues will come in a single day, death and mourning and famine, and she will be burned up with fire; for mighty is the Lord God who has judged her."

The downfal and destruction of the mystical Babylon are determined in the counsels of God. Another angel comes from heaven. This seems to be Christ himself, coming to destroy his enemies, and to shed abroad the light of his gospel through all nations. The wickedness of this Babylon was very great; she had forsaken the true God, and set up idols, and had drawn all sorts of men into spiritual adultery, and by her wealth and luxury kept them in her interest. The spiritual merchandise, by which multitudes have wickedly lived in wealth, by the sins and follies of mankind, seems principally intended. Fair warning is given to all that expect mercy from God, that they should not only come out of this Babylon, but assist in her destruction. God may have a people even in Babylon. But God's people shall be called out of Babylon, and called effectually, while those that partake with wicked men in their sins, must receive of their plagues.
