In warning about complicity and taking part in Rome’s excesses - Babylon the Great - Jesus in Revelation quoted from God speaking a similar warning about the original Babylon (Jeremiah 51) which shows that the reason for it all is the vengeance to be shown against what remains of the Roman Empire and especially Rome itself because of all those past crucifixions of Christians and persecutions along such lines and self-obsessed oppulence and wrongly acruee wealth. We need to part company and remove ourselves from involvement so as not to share in its ongoing sins and the ensuing plagues which result from them. This means political AND commercial exit.
6“Flee from Babylon!
Run for your lives!
Do not be destroyed because of her sins.
It is time for the Lord’s vengeance;
he will repay her what she deserves.
7Babylon was a gold cup in the Lord’s hand;
she made the whole earth drunk.
The nations drank her wine;
therefore they have now gone mad.
8Babylon will suddenly fall and be broken.
Wail over her!
Get balm for her pain;
perhaps she can be healed.
...
11“Sharpen the arrows,
take up the shields!
The Lord has stirred up the kings of the Medes,
because his purpose is to destroy Babylon.
The Lord will take vengeance,
vengeance for his temple.
12Lift up a banner against the walls of Babylon!
Reinforce the guard,
station the watchmen,
prepare an ambush!
The Lord will carry out his purpose,
his decree against the people of Babylon.
13You who live by many waters
and are rich in treasures,
your end has come,
the time for you to be destroyed.
14The Lord Almighty has sworn by himself:
I will surely fill you with troops, as with a swarm of locusts,
and they will shout in triumph over you.
15“He made the earth by his power;
he founded the world by his wisdom
and stretched out the heavens by his understanding.
16When he thunders, the waters in the heavens roar;
he makes clouds rise from the ends of the earth.
He sends lightning with the rain
and brings out the wind from his storehouses.
