Description of Babylon
But, but, but Lord--we're your people and the foremost growing denomination worldwide. After all, we're reaching out to Rome, seeking unity in brotherhood.
TEKEL; Thou art weighed in the balances, and art found wanting. Daniel 5:27
Babylon is said to be “the mother of harlots.” 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. In the words of the prophet to Israel: “Thy renown went forth among the heathen for thy beauty: for it was perfect through My comeliness, which I had put upon thee, saith the Lord God.” 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. GC 382.3
Thus the message of the third angel will be proclaimed. As the time comes for it to be given with greatest power, the Lord will work through humble instruments, leading the minds of those who consecrate themselves to His service. The laborers will be qualified rather by the unction of His Spirit than by the training of literary institutions. 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. In amazement they hear the testimony that Babylon is the church, fallen because of her errors and sins, because of her rejection of the truth sent to her from heaven. As the people go to their former teachers with the eager inquiry, Are these things so? the ministers present fables, prophesy smooth things, to soothe their fears and quiet the awakened conscience. But since many refuse to be satisfied with the mere authority of men and demand a plain “Thus saith the Lord,” the popular ministry, like the Pharisees of old, filled with anger as their authority is questioned, will denounce the message as of Satan and stir up the sin-loving multitudes to revile and persecute those who proclaim it. GC 606.2
Babylon is any church clinging to her doctrines and tradition.
And why call ye me, Lord, Lord, and do not the things which I say? Luke 6:46
Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.  Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?  And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
