Babylon is said to be "the mother of harlots." By her daughters must be symbolized churches that cling to her [RCC] 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}

Many of the Protestant churches are following Rome's example of iniquitous connection with "the kings of the earth"--the state churches, by their relation to secular governments; and other denominations, by seeking the favor of the world. And the term "Babylon"--confusion--may be appropriately applied to these bodies, all professing to derive their doctrines from the Bible, yet divided into almost innumerable sects, with widely conflicting creeds and theories. {GC 383.1}

Dear Brethren of the General Conference:

I testify to my brethren and sisters that the church of Christ, enfeebled and defective as it may be, is the only object on earth on which He bestows His supreme regard. While He extends to all the world His invitation to come to Him and be saved, He commissions His angels to render divine help to every soul that cometh to Him in repentance and contrition, and He comes personally by His Holy Spirit into the midst of His church. {TM 15.1}

Although there are evils existing in the church, and will be until the end of the world, the church in these last days is to be the light of the world that is polluted and demoralized by sin. The church, enfeebled and defective, needing to be reproved, warned, and counseled, is the only object upon earth upon which Christ bestows His supreme regard. The world is a workshop in which, through the cooperation of human and divine agencies, Jesus is making experiments by His grace and divine mercy upon human hearts. {TM 49.1}

My brother, I learn that you are taking the position that the Seventh-day Adventist Church is Babylon, and that all that would be saved must come out of her. You are not the only man the devil has deceived in this matter. For the last forty years, one man after another has arisen, claiming that the Lord has sent him with the same message; but let me tell you, as I have told them, that this message you are proclaiming is one of the satanic delusions designed to create confusion among the churches. {TM 58.4}

And all that believed were together, and had all things common; (Acts 2:44, KJV)
And sold their possessions and goods, and parted them to all men, as every man had need. (Acts 2:45, KJV)
And they, continuing daily with one accord in the temple, and breaking bread from house to house, did eat their meat with gladness and singleness of heart, (Acts 2:46, KJV)
Praising God, and having favour with all the people. And the Lord added to the church daily such as should be saved. (Acts 2:47, KJV)

Not salvation through church membership, but church membership through salvation.
