Prop,
You wrote: The word "freedom" or "captivity" is not mentioned in Revelation 18. So why does this become a central part of your interpretation?
As I have said, Babylon was the nation which took God's people as captives and it was also the place where they were long held as slaves. So for the Jewish people, both at the time Revelation was written and even still today, the words "Babylon" and "bondage" were virtually synonymous. How this obvious symbolism can be missed by any reader of Revelation is beyond me.
If I were to write an allegory in which the city of "Washington D.C." played a central role, would it really be necessary for me to use the words "government" or "politics" to tip off my readers that those things were what I intended to draw attention to by my use of "Washington D.C." ?
You wrote: The command is "Get out of her my people". What are God's people doing in "false religion" or "false christianity"?
First of all, I don't view "Babylon the Great" as being "false religion" or even as being "false Christianity". I understand "Babylon the Great" as portraying corrupted Christianity, parts of which God approves of and parts of which he disapproves of. Just as I do not believe the legalistic Judaism which existed at the time of Christ, was considered by him as being "false" religion or "false" Judaism. Rather, I believe the Judaism which existed at the time of Christ was viewed by him as being a corrupted form true worship, a worship which God then partly approved of and partly disapproved of.
You wrote: If they have the label "my people" than they are free of any enslaving deception.
I disagree. Again consider the corrupted Jewish religion which existed at the time of Christ. Even though virtually all aspects of organized Judaism which then existed had become corrupted by various manmade traditions and teachings, Christ's followers and even Jesus Christ himself actively participated in Jewish religious services as they then existed.
You wrote: The command to "Get out of her" is given to those who have already left behind the enslaving ideas of this world.
I don't see it that way. I believe a time is coming when organized Christianity will be banned worldwide, possibly under penalty of death to those who continue to support it. As I said earlier, I believe this ban may be imposed upon all religion by a worldwide government. Or maybe radical Islam will one day conquer the world and then do on a global scale what it now does on a local scale when its practitioners gain political control of a region, ban all other religions and be particularly hard on Christians.
At that time many Christians will no doubt have a very hard time letting go of their particular Christian sectarian practices. By failing to understand that true Christianity is a way of life based upon a personal relationship with God and Christ, not a relationship with a manmade religious organization centered around a Church building, I fear many Christians will then refuse to "get out of" "Babylon the Great" and, by so doing, I fear many Christians may then unnecessarily end up losing their lives.
