Babylon is said to be ‘the mother of harlots’ (Revelation 17:5). By her daughters must be symbolized churches that cling to her doctrines and traditions, and follow her example of sacrificing the truth and the approval of God, in order to form an unlawful alliance with the world. The message of Revelation 14, announcing the fall of Babylon must apply to religious bodies that were once pure and have become corrupt. Since this message follows the warning of the judgment, it must be given in the last days; therefore it cannot refer to the Roman Church alone, for that church has been in a fallen condition for many centuries. Furthermore, in the eighteenth chapter of the Revelation the people of God are called upon to come out of Babylon. According to this scripture, many of God’s people must still be in Babylon. And in what religious bodies are the greater part of the followers of Christ now to be found? Without doubt, in the various churches professing the Protestant faith. At the time of their rise these churches took a noble stand for God and the truth, and His blessing was with them. Even the unbelieving world was constrained to acknowledge the beneficent results that followed an acceptance of the principles of the gospel. … But they fell by the same desire which was the curse and ruin of Israel—the desire of imitating the practices and courting the friendship of the ungodly. ‘Thou didst trust in thine own beauty, and playedst the harlot because of thy renown.’ Ezekiel 16:14, 15.” The Great Controversy, 382, 383.

“The fallen denominational churches are Babylon. Babylon has been fostering poisonous doctrines, the wine of error. This wine of error is made up of false doctrines, such as the natural immortality of the soul, the eternal torment of the wicked, the denial of the pre-existence of Christ prior to His birth in Bethlehem, and advocating and exalting the first day of the week above God’s holy and sanctified day. These and kindred errors are presented to the world by the various churches, and thus the Scriptures are fulfilled that say, ‘For all nations have drunk of the wine of the wrath of her fornication’ (Revelation 18:3). It is a wrath which is created by false doctrines, and when kings and presidents drink this wine of the wrath of her fornication, they are stirred with anger against those who will not come into harmony with the false and satanic heresies which exalt the false sabbath, and lead men to trample underfoot God’s memorial.” Testimonies to Ministers and Gospel Workers, 61, 62.
