Revelation 18 is depicting a three fold NWO union of "Babylon" which is the papacy, "kings of the Earth" which are the leaders in cahoots with her, and the "merchants of the Earth" which are the economic elite. Of course this union did not exist in John's day.
That's the easiest question I've had all day: "Here is the patience of the saints. Here are they who keep the commandments of God and have the faith of Jesus." Revelation 14:12
....and that's the stupidest thing I've heard all day...The Bible is clear that God has His people in Babylon (Revelation 18:4) and is calling for them to come out of Babylon before they are destroyed with it. So, do you now understand that while the Bible identifies the papacy (the union of the catholic church and the secular state) as "Babylon", it does not condemn anyone who has been deceived by Babylon's teachings, but calls for them to come out of her and follow only Christ?
Babylon has "daughters" - apostate Protestant churches which teach an unBiblical Christ, commandments of men, and will eventually unite with the papacy in persecution of God's true faithful...of course you won't believe it - most don't want to. Because the idea of giving one's self fully, totally, 110% in surrender to Christ -- what we think, what we say, what we eat, what we drink, where we go, what forms of entertainment we imbibe, etc. -- is just too much; it is "offensive" to them, as Paul said the Cross would be, so they delude themselves with false Christs which say, "do what thou wilt shall be the whole of the law", unto their own destruction.
