Babylon used to be a City!
A city of wealth (also found in the old testament of the Bible (and in the Torah). One of the reasons why it became so popular was because there was a lot of perversion, black market and stuff, and like in rich countries usually the case is, no hope or faith in a God.
God destroyed that city, just like He will destroy all the new Babylons that possibly will arrise (places that reject theMaker).
There is a legend there will arrise (again) a new Babylon (-on the spot of the old city or not- I don't know), and the Antichrist would arrise from that place.
When the name 'Babylon' is given to a city, it has got nothing to do with the well-fare of the city, for God doesn't judge wellfare, but He does judge unbelief!
But many explenations can indeed be told.
The history of the Bible learns us that people of that time, who lived in disgrace, wore a bad name 'till the end of their lives, or even longer.
Evry time they spoke of that bad name again, they remind that bad person (Look to Jezebel, who died falling off a wall (in the Bible), and the dogs eating her flesh; That woman's name is still been seen as a demon, or a extremely bad habit).
If someone of that time called you a Jezebel, she spoke a curse over you, or resembled your character with Jezebels.
Or look to Thomas: a man who doubted the ressurected Jesus was real. Still today the saying remains (in our language (= Dutch) it says The unbelieving Thomas; or the doubting Thomas)
So of the city, Babylon, it's a name reminding people of what happened there when the first Babylon (the one of the Bible) still existed.
It is a way of living; If you have a Babylon system in religious terms it means with no order, no laws, no God...
I'm not a theologican, and most of wha I wrote came of the little knowledge I have.
Should I have said anything wrong, I appologise for that; as you know I'm also but a man.
I thank the Holy Spirit, who grabbed these thoughts from my heart, and placed them in text; I tried to be as carefull as possible
but again Im still human
I hoped to be of service to you with this
Greetings in Christ Jesus
