What about this for a suggestion:
Two key Scriptures in Revelation may help to give a clearer view as to whom the name "Babylon the Great" applies. At Revelation 17:5,6 it 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", and 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."
Firstly, Revelation 17:5 says that Babylon is the "mother" of the harlots - namely, the one who is supremely responsible for the existence of other "harlots". Therefore, since there are other harlots outwith the designation of Babylon the Great, then clearly, the mysterious Babylon the Great does not include these other harlots.
It cannot represent the "world empire of false religion" since other harlots exist outwith the title of B t G.
She stands alone, distinct! What makes her distinctive?
Both of the verses quoted above indict her; she has been responsible for the persecution and killing of a great number of particular individuals - and they were all faithful servants of the God of the Bible. It speaks of "prophets" and "the witnesses of Christ", namely, pre-Christian and Christian servants.
A study of the Hebrew and Greek Scripture 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, both Jewish or Christian, 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". (Rev. 18:4)
All who are sincere Christians have no need to be part of money-making religions to justify their faith. One is their Leader - Christ!
Just another line of reasoning to consider!
