Is the Babylon mentioned in 1 Peter 5 the same Babylon that is mentioned in Revelation?....
Babylon is a code-word for Rome. It is used that way multiple times in works like the
Sibylline Oracles (5:159f), the
Apocalypse of Baruch (2:1), and
4 Esdras (3:1). Eusebius Pamphilius, in
The Chronicle, composed about A.D. 303, noted that “It is said that Peter’s first epistle, in which he makes mention of Mark, was composed at Rome itself; and that he himself indicates this, referring to the city figuratively as Babylon.”
Consider now the other New Testament citations: “Another angel, a second, followed, saying, ‘Fallen, fallen is Babylon the great, she who made all nations drink the wine of her impure passion’” (Rev. 14:8). “The great city was split into three parts, and the cities of the nations fell, and God remembered great Babylon, to make her drain the cup of the fury of his wrath” (Rev. 16:19). “[A]nd on her forehead was written a name of mystery: ‘Babylon the great, mother of harlots and of earth’s abominations’” (Rev. 17:5). “And he called out with a mighty voice, ‘Fallen, fallen is Babylon the great’” (Rev. 18:2). “[T]hey will stand far off, in fear of her torment, and say, ‘Alas! alas! thou great city, thou mighty city, Babylon! In one hour has thy judgment come’” (Rev. 18:10). “So shall Babylon the great city be thrown down with violence” (Rev. 18:21).
These references can’t be to the one-time capital of the Babylonian empire. That Babylon had been reduced to an inconsequential village by the march of years, military defeat, and political subjugation; it was no longer a “great city.” It played no important part in the recent history of the ancient world. From the New Testament perspective, the only candidates for the “great city” mentioned in Revelation are Rome and Jerusalem.
