The sins of Babylon will be laid open
“After these things I saw another angel coming down from heaven, having great authority, and the earth was illuminated with his glory. And he cried mightily[a] with a loud voice, saying, “Babylon the great is fallen, is fallen, and has become a dwelling place of demons, a prison for every foul spirit, and a cage for every unclean and hated bird! For all the nations have drunk of the wine of the wrath of her fornication, the kings of the earth have committed fornication with her, and the merchants of the earth have become rich through the abundance of her luxury.” Revelation 18: 1-3
“Men of faith and prayer will be constrained to go forth with holy zeal, declaring the words which God gives them. The sins of Babylon will be laid open. The fearful results of enforcing the observances of the church by civil authority, the inroads of Spiritualism, the stealthy but rapid progress of the papal power,–all will be unmasked. By these solemn warnings the people will be stirred. Thousands upon thousands will listen who have never heard words like these.” (The Great Controversy, p. 606)
