Who Is the Harlot Babylon?

Opening: A Crowded, Confusing Scene

Revelation 17 throws a lot at you at once: a beast, seven heads that are also seven hills, ten horns that are also ten kings, and — riding on top of all of it — a woman dressed in purple and scarlet, glittering with gold and jewels, holding a golden cup, with a strange title written on her forehead: “Babylon the Great, Mother of Harlots.” It can read like a riddle wrapped in a nightmare.

But this scene resolves faster than it looks like it will, once you know where to start looking. And once it resolves, it stops being a first-century puzzle and becomes one of the most searching questions Revelation asks of the Church in any century — including ours.

Where to Start: The Seven Hills

The angel who guides John through this vision doesn’t leave the identification a total mystery. “The seven heads are seven hills on which the woman sits” (Revelation 17:9). Everyone in the ancient world knew a city built on seven hills: Rome. This is not a contested reading dreamed up by modern scholars trying to be clever — it is about as close to a unanimous identification as you’ll find anywhere in Revelation’s symbolism, held by ancient and modern interpreters alike, Catholic scholarship very much included. Whatever else this vision is doing, it is doing it with Rome specifically in view.

A Mocking Counterfeit

Look closer at the beast the woman rides, and something sharper comes into focus. It is described as one “who was, and is not, and is to come” (Revelation 17:8, 11). Stop and set that beside how God describes himself at the very opening of this book: “who is, and who was, and who is to come, the Almighty” (Revelation 1:8).

That is not a coincidence. It’s a parody — and a deliberately mocking one. Imperial Rome, in John’s vision, is dressed up in language that imitates God’s own eternity, God’s own sovereignty over history. The point is not subtle: political power that postures as ultimate, as though it holds the keys to history the way only God does, is putting on a costume it has no right to wear. Revelation is exposing the theft.

The Puzzle of the Kings — and Why We Don’t Need to Solve It

Revelation 17:10 adds a harder detail: “five have fallen, one is, the other has not yet come.” Readers across the centuries have tried to match this to specific Roman emperors, starting the count at Julius Caesar, Augustus, or Caligula, and land in different places — the text doesn’t say where to start counting. It’s worth naming that disagreement honestly rather than pretending it isn’t there.

But Revelation uses numbers symbolically everywhere else — seven for completeness, twelve for God’s people, ten for a full but limited span. Read that way, “five fallen, one is, one to come” is less a puzzle for a history textbook than a way of saying the countdown is far along and the end is close. You don’t need to resolve the emperor-counting debate to receive that point.

Dressed Like the Sacred, Wearing Something Profane

Now look at what the woman is wearing. Purple, scarlet, gold, pearls, precious stones (Revelation 17:4; 18:16) — this is not incidental luxury. It closely echoes the description of the high priest’s sacred vestments in Exodus 25 and 28, woven with the same purple and scarlet, set with precious stones. That’s the parody again, this time aimed at religion rather than politics: the harlot dresses like something holy while being, underneath, profane. She has the appearance of sanctity draped over an entirely different reality.

An Old Accusation, Reused

This is not a new accusation — it’s Israel’s own prophets’ oldest complaint, redirected. Jeremiah 2-4 pictures unfaithful Judah as a harlot chasing other lovers. Ezekiel 16 does the same to Jerusalem in searing detail: a city given everything by God, who used his gifts to seduce and be seduced by foreign powers. Isaiah 23 levels a similar charge at Tyre, a wealthy trading city, using the same “harlot’s wages” language (Isaiah 23:16-18) that Revelation echoes.

Revelation takes the accusation Israel’s own prophets once aimed at unfaithful Jerusalem and aims it at Rome. And notice what the charge actually is: never simply “this city has money,” but that covenant loyalty gets traded away for wealth, security, and status — a trade that rarely announces itself as apostasy. It arrives through alliances that look practical: tribute dressed as temple gifts, trade dependency that becomes political dependency, a royal marriage (Jezebel’s, most famously) importing foreign gods along with foreign wealth. Scripture doesn’t treat commerce and idolatry as separate categories. Economic entanglement has a way of becoming religious entanglement.

The Takeaway: Babylon Is a Pattern, Not Just a Place

So who is the harlot? In the first century, the answer is concrete: Rome, the empire that demanded worship of the emperor, that seduced the known world with wealth and spectacle and promised security, that clothed raw political power in the trappings of the sacred.

But if that were the whole answer, this vision would have nothing to say to us. The deeper answer Revelation is pointing toward is this: “Babylon” is less a single place than a recurring pattern — any system, economic, political, or cultural, that seduces God’s people into trading covenant faithfulness for wealth, security, and status, all while wearing the appearance of legitimacy or even holiness. That is precisely why Revelation later commands, “Come out of her, my people” (Revelation 18:4) — not as a call to flee a city on a map, but as a summons the Church must be willing to hear addressed to itself, in every age, including our own.

Living This Out

This isn’t a comfortable session to sit with, and it isn’t meant to be. The real question Revelation 17-18 leaves for the Church isn’t “was Rome bad?” History has settled that. It’s whether we have quietly moved into Babylon ourselves — whether comfort, security, prestige, or wealth have become non-negotiables we protect even at the cost of faithfulness, dressed up in language that sounds sacred. Ask concretely: where is loyalty to Christ quietly losing out to loyalty to comfort or status in my own life, while still looking entirely respectable from the outside? That is the harlot’s oldest trick — never announcing herself as an enemy of God, always arriving dressed like something you’d want to trust.

Closing

Revelation names Rome, but it doesn’t stop there. Every generation of the Church is invited to ask the same question John’s first readers had to ask: have we been seduced by a power that promises security and glitter in exchange for our first loyalty? The good news is that the same book that exposes Babylon also promises her fall is certain (Revelation 18:2) and that a wedding feast, not a funeral, is what God’s people are ultimately headed toward (Revelation 19:7-9). Babylon’s glamour is not the last word.

For Preparation

Discussion questions:

1. Where do you see wealth, security, or status quietly outcompeting faithfulness to Christ in your own life — even in ways that look perfectly respectable to others?
2. Read Ezekiel 16 alongside Revelation 17-18. How does it change the force of Revelation’s accusation against Rome to know that Israel’s own prophets first leveled nearly identical language at unfaithful Jerusalem?
3. The harlot dresses like the high priest but is corrupt underneath. Where might the Church, or you personally, need to examine whether an appearance of holiness is covering something less faithful underneath?
4. “Come out of her, my people” (Revelation 18:4) is addressed to God’s own people, inside Babylon. What would “coming out” concretely look like for you this week, without requiring you to physically go anywhere?

Song/hymn suggestions: “Turn Back, O Man”; “O Jesus, Thou Art Standing”; “Lord, Whose Love in Humble Service” (for its themes of costly, uncompromised discipleship); consider closing with quiet reflection rather than a triumphant hymn, letting the challenge of this session settle before moving to the hope of Revelation 19-21 in coming sessions.
