John saw an angel announce,
“Babylon is fallen, is fallen, that great city, because she has made all nations drink of the wine of the wrath of her fornication” (Revelation 14:8).
Babylon in the Book of Revelation represents Rome in its various phases, and even as pagan Rome fell, so someday papal Rome shall fall.
The only thing that shall remain forever is the church. Are you an active member of the Body of Christ?
