Two key Scriptures in Revelation give a description of BTG, and by doing so, identify to whom the name "Babylon the Great" applies.
Revelation 17:5,6 says, "Babylon the Great, the mother of the harlots and of the disgusting things of the earth." And I saw that the woman was drunk with the blood of the holy ones and with the blood of the witnesses of Jesus".
Revelation 18:24 says, "Yes, in her was found the blood of prophets and of holy ones and of all those who have been slaughtered on the earth."
Revelation 17:5 reveals that Babylon is the "mother" of the harlots - namely, the one who is considerably worse in her practices than that of her counterparts, the other "harlots".
Therefore, since there are other harlots outwith the designation of Babylon the Great, then clearly, the mysterious designation of "Babylon the Great" does not include these other harlots. She stands alone, distinct! What makes her distinctive?
Both of the verses quoted above indict her and condemn her, because she has been liable for the persecution and deaths of a great number of particular individuals who were all faithful servants of the God of the Bible.
The verses speak of "prophets" and "the witnesses of Christ", individuals who were pre-Christian and Christian servants. A study of the Scriptures identifies who has been overwhelmingly responsible for the evil committed on God's servants; not the governments, not Baal worshipers or any other heathen people - it was the religious leaders of these people, who perverted true worship and persecuted all who tried to expose them!
Consequently, all those involved with religions claiming to be Christian, are in reality part of Babylon the Great! Hence the cry from God, "Get out of her my people if you do not want to share in her sins." (Rev.18:4) As 1 Peter 4:17 states, "the judgment starts first with the house of God" Of all the religions in the world, the religious leaders who have claimed to represent the God of the Bible have been the most reprehensible in God's eyes, because of their treatment of sincere worshippers of the one true God. (Matt. 21:31-41) All who are sincere Christians have no need to be part of money-making religions to justify their faith. The Bible states that there is "one Lord, one faith, one baptism". It does not say "one religion". Faith is required for salvation, not religion!
