Peter didn’t write Revelation, so his use of “Babylon” doesn’t necessarily correlate with that in Revelation.
Peter didn’t write Revelation...
But he did know the guy who did (John) and spent a lot of time around and with him. Peter also knew Jesus Christ, who just happens to be God. Babylon = ROME. The 4th beast is ROME. The LITTLE HORN comes out of ROME and last until the second coming of Jesus Christ. The Catholic Church = ROME. No doubt about it.
