Parenthetical Scene 6.2: The image of this messenger descending in Revelation 18:1 may connect thematically with the events surrounding Revelation 14:1–8. The repeated phrase "is fallen, is fallen Babylon the great" strengthens that connection, since Revelation 14:8 gives the announcement before the mark warning and before the promised wrath is poured out. If this messenger is understood to be Jesus, as can be argued from "the earth was lightened with his glory" (Ezekiel 43:2), then the scene would represent the period when Jesus is depicted as active on earth in the early part of the tribulation. After this moment, He is again seen in heaven by 19:5 for his own wedding supper.

Furthermore, the expression "another messenger" does not automatically exclude a Christophanic identification. Revelation 10 demonstrates that Christ can be described in messenger terms within the visionary framework. And in Revelation, glory is associated with God and the Lamb (Rev 5:12–13; 21:23). To attribute such radiant, earth-illuminating glory to an unnamed messenger feels out of place, especially given Revelation's deep connection to Ezekiel and, thereby, possibly Ezekiel 43:2's messenger of the Lord. Therefore, while the identification of this messenger as Jesus cannot be asserted dogmatically, the possibility that this descending figure could represent Christ is not impossible.

Yet, this might not be the case. Here is why this messenger might not be Jesus.

Glory is not attributed exclusively to the Lamb and God in Revelation. Making that claim of glory being only used for God, on its own, is a weak argument. In Revelation 21:10, holy Jerusalem has the glory of God, and the kings bring their "glory" into New Jerusalem. Further, while Ezekiel 43:2 is a strong case of Jesus being the messenger's parallel for lighting the earth, there is also a messenger in Luke 2:9 who shines with the glory of God on earth: "an angel of the Lord suddenly stood near them, and the glory of the Lord shone around them" (NASB). Thus, having light and glory is not a rare attribute for a messenger. Further, this messenger in 18:1 does not light the "whole" earth; the messenger only lights the earth in general. Yet, this messenger in 18:1 does not qualify his glory with God as the one in Luke 2:9 does.

Also, the mirror speaker in Isaiah 21:6-9 is identified contextually as the watchman appointed by the LORD, a figure who observes and proclaims what is revealed. This establishes a broader biblical pattern in which a commissioned messenger declares divine judgment. A similar function appears here in Revelation 18:2 (cf. Rev 14:8), where the messenger announces, “is fallen, is fallen Babylon the great.” While the texts do not explicitly equate the figures, the shared role — receiving and proclaiming God’s verdict — suggests a functional parallel, in which the messenger may be understood as fulfilling a watchman-like office, acting as a herald under divine authority, not as the Lord himself.

If the figure in Revelation 18:1 were identified as Jesus, then the voice in 18:4 becomes difficult to account for, since that voice also carries features that strongly suggest Christ—particularly in the covenantal language, “my people.” The text presents the messenger of 18:1 as having descended to the earth, while the voice of 18:4 speaks from heaven, creating a clear spatial and functional distinction between the two. Taken together, these differences indicate that the speakers are being presented as separate figures within the passage.

Finally, in Revelation 14:8, we appear to see the same messenger with no descriptive terms, saying "is fallen, is fallen." And Revelation 14 is a chapter in which Jesus is clearly present and described multiple times (14:1 and 14:15). Thus, if the messenger in 18:1 is the messenger in 14:8, it does not make sense for the text to portray Jesus as a nondescript messenger a few verses later in 14:8 (even if the messenger in 14:8 is nondescript intentionally to bring focus to the message and the speaker).

18And After these things, I saw another messenger (j) come down from heaven, having great power; and the earth was lightened with his glory. [r.0]

αλλον — another (of the same kind).

[fn]

If this messenger is Jesus—which is not implausible—then Revelation 14:1-5 may function as an overlay to Revelation 14:6-8. This pattern of overlaying is not exclusive to Revelation 14, nor does it introduce a unique narrative structure. We already see possible examples of overlapping scenes elsewhere in Revelation, such as in chapter 6, where the four horsemen appear to emerge in rapid succession or at the same time, and in chapter 7, with the sealing of the 144,000 alongside the vision of the multitude in heaven. In other words, Revelation appears to contain tightly grouped events that may be presented either linearly or as compressed overlays.

(j)

Re 18:1, Re 14:8This messenger's announcement, "is fallen, is fallen Babylon the great," sounds again from the messenger of 18:1-2. If the two are the same messenger, then the announcement of 14:8 is also cried out greatly (see the note at 14:8).

2 And he cried with a strong voice, saying, is fallen, is fallen Babylon the great (b) [r.1] [r.2], and is become the dwelling place of demons [r.3] [r.4], and the prison of every unclean spirit, and the prison of every unclean and hateful bird[, and the prison of every unclean beast].
[lex]

“ἰσχυρᾷ φωνῇ” — “with a strong voice” — This phrase occurs only once in the New Testament, here in Revelation 18:2. In contrast, the more common expression, used roughly sixty times, is φωνῇ μεγάλῃ (“with a great voice”). The distinction is significant. This messenger is not merely portrayed as speaking with great volume—though he may be—but as speaking with strength, force, and authority. His words carry weight; they are deliberate, powerful, and commanding. The closest parallel is found in Hebrews 5:7, where Christ offers prayers with “strong crying” (κραυγῆς ἰσχυρᾶς), yet there the expression conveys anguish and supplication, not the authoritative proclamation seen here.

This phrase also reinforces what is already revealed about the messenger: he comes with “great power” (Rev 18:1). And the strong-word (ἰσχυρός) runs through the whole Babylon judgment in a deliberate chain of five: the messenger cries with a strong voice (18:2), “strong is the Lord God who judges her” (18:8), Babylon is mourned as “the strong city” (18:10), a strong messenger casts the millstone that is her fall (18:21), and the strong thunders join the Alleluia over her judgment (19:6). The announcers of the judgment, the God who judges, and the voices that celebrate it all stand against the city’s claimed strength with her own word — and theirs is the greater.

Re 14:8, Re 17:2, Re 18:3

Important Note: Greek grammar suggests this voice should belong to someone other than the angel we just saw who lightens the earth. Now, we might be tempted to say this is the Father. But in verse 5, the voice says "…God has remembered her unjust deeds." The Father is not likely to refer to Himself in the third person. That alone makes a direct speech from the Father unlikely. Also, keep in mind that prophecy can break ordinary storytelling rules. It can intentionally leave out details and expect you to use prior knowledge to simply "know" who is speaking. The expectation is that we know the details well enough to identify the speaker from context.

4 And I heard another voice from heaven [r.6], saying, Come out of her, my people (r) [r.7], that you all be not partakers of her sins, and that you all receive not of her plagues.
[fn]

This heavenly voice that calls "my people" to "come out" does not use the same Greek word as we first see when John is told to "Come up" or "Ascend" in Revelation 4:1. That observation should stand: because the text does not use the established ascent formula, we should not jump right to reading this call as the same kind of summons. A command like this can fall into two kinds: a command of initiative, where the hearers act, or a command of power, where the call itself carries the movement, like the calls to ascend in 4:1 and 11:12. The wording itself follows the Old Testament come-out-of-Babylon formula: "My people, go ye out of the midst of her" (Jeremiah 51:45), "Go ye forth of Babylon" (Isaiah 48:20), "go ye out of the midst of her" (Isaiah 52:11) — a formula of self-agency, a call to run out. Because the context is the same — leaving Babylon — this is where the call most confidently lands: it follows the prophets' flee-Babylon formula, not the ascent formula, so by its wording it does not appear to be a catching-up call. Isaiah 26:20 uses a similar address, "Come, my people," in a setting of resurrection and shelter from indignation, but that setting is general rather than Babylon-specific, so it should not be imported here directly. And the "come out" connection is not needed to establish where the saints arrive. In Revelation 19 we see the ultimate destination apart from any need to interpret "come out" in any direction, out or up: the fall of Mystery Babylon is bound directly to the wedding — the great multitude is in heaven (19:1), the woman has prepared herself, and she is given her garments (19:7-8). Revelation 19 places the saints in heaven for a wedding already, without the need for that connection. So we need not build up a connection the text does not demand and that fits loosely — though one might with Isaiah 26.

Re 18:4, Re 7:14ἔρχομαι — to come. Used in many places and not distinct to 7:14 and 18:4, but a connection in the language nonetheless. The call at 18:4 follows the prophets’ come-out-of-Babylon wording (Jeremiah 51:45; Isaiah 48:20), and the group called out is then seen in heaven directly after her fall (19:1) — the arrival standing on Revelation 19’s own scene, whichever way the verb is read.

The Father does not speak of himself in third person in the way this speaker is talking. Thus, the grammar suggests that the speaker is not the Father Himself, but one who speaks on His behalf with covenantal authority, most coherently understood as the risen Christ, who both claims the people and announces the Father’s judicial action.

6 Repay her even as she repaid you, and double unto her double according to her works [r.8]: in the cup which she has mixed, mix to her double. Jeremiah 17:18
[lex]

In the Critical Text, "Repay her" does not state that "you" (σύ), the saints, are to be the ones rewarding her as the TR/KJV does.

[fn]

The motif of “double” recompense reflects the principle of full and just repayment rooted in the Law (Exod 22:4, 7) and developed in the Prophets (Jer 16:18; 17:18), culminating in the judgment of Babylon where she receives “double” according to her works (Rev 18:6), a pattern that can also reverse into restoration for God’s people (Isa 40:2; 61:7).

Re 11:8, Re 16:19, Re 17:18, Re 18:10, Re 18:16, Re 18:18, Re 18:19The phrase “the great city” (ἡ πόλις ἡ μεγάλη) appears to function as a theologically loaded designation in Revelation, used predominantly for Babylon (Rev 17:18, 18:10, 18:16, 18:18, 18:19), yet applied to Jerusalem in Revelation 11:8—“where also their Lord was crucified.” In that context, Jerusalem is “spiritually” called Sodom and Egypt, indicating a transformation from its identity as the “holy city” (Rev 11:2) into one aligned with paradigmatic centers of rebellion and judgment. This suggests that Revelation is not using the term merely geographically, but associating it with a city’s spiritual condition and opposition to God.

Because Revelation 17:18 defines “the great city” as the one that “has kingship over the kings of the earth,” it may be inferred that the designation corresponds to a center of dominant, God-opposing power. When read alongside Revelation 11:8, this raises the possibility that Jerusalem, in its corrupted state and in connection with the rise of the beast, temporarily participates in that same category (it is possible to infer from Daniel 11:45 and 2 Thessalonians 2:4 that Jerusalem becomes a focal point of the final ruler’s activity). However, while this pattern allows for a typological relationship—because Babylon is “the great city”—the text does not explicitly state that the title transfers sequentially or that Jerusalem becomes identical with “Mystery Babylon.” Thus, “the great city” may function as a theological marker for a ruling, rebellious center.

As for Revelation 16:19, also marked as "the great city," it does not automatically become Jerusalem or Mystery Babylon; such a claim must remain a reasoned inference drawn from the book’s patterned language rather than an explicit textual claim. And, since it is not likely Mystery Babylon for numerous reasons, it very well could be Jerusalem as the ruling city of the sea beast.

Important Note: In Revelation 16, when Jerusalem is split into three parts, it also says "the cities of the nations fell." So this Babylon cannot be the same immediate scene because the kings weep and wail and the merchants weep and mourn for her fall, which implies their cities are still standing. Who will lament her if all have fallen? This does not erase the Babylon language in Revelation 16:19; it simply keeps the judgment scene in 16:19 distinct from the lament scene in Revelation 18.

11 And the merchants of the earth shall weep and mourn over her; for none buys their merchandise any more:

The expression “such vast riches” renders the Greek ὁ τοσοῦτος πλοῦτος (NA28). The adjective τοσοῦτος (tosoutos) denotes quantity or extent—“so much,” “of such magnitude”—rather than merely describing quality. Thus, the phrase emphasizes the immense scope of the riches rather than simply calling them “great.” A more strictly literal sense would be “so much riches” or “riches of such extent,” highlighting the overwhelming abundance that is suddenly brought to ruin “in one hour.”

Re 18:8, Re 18:20, Re 19:2

Important Note: This is an echo, using prophetic imagery, of the fall of Mystery Babylon. We have already seen Mystery Babylon fall, and now the text foretells that same event again for emphasis. The event is sure and will happen.

21 And a strong messenger [r.37] lifted up a stone as a great millstone, and cast it into the sea [r.38], saying, So with violence shall the great city Babylon [r.39] be cast down, and shall be found no more at all [r.40].
[fn]

Babylon's "no more" is emphatic and absolute. The Greek carries the strong double negative with ἔτι (οὐ μὴ εὑρεθῇ ἔτι, "shall not be found any longer"), and 18:21-23 repeats the formula against her — found no more, heard no more, shine no more — while the book's other absolutes speak the same way: death "no more" (21:4), curse "no more" (22:3). And where Revelation intends a bounded "no more," it says so in the same breath: Satan deceives the nations no more "till the thousand years should be finished" (20:3). Babylon's formula carries no "till." Therefore, when Mystery Babylon is said to be "found no more at all," it must be understood as final. This cannot refer directly to the "great city" in Revelation 16 as the same immediate city-event, because in Revelation 16:19, "the great city was divided into three parts, and the cities of the nations fell." That city is shaken but not destroyed—it remains the city to which Christ returns. Mystery Babylon, by contrast, is utterly annihilated and remembered no more.

Re 5:2, Re 10:1, Re 18:21"strong messenger" does not appear to identify a specific identity; "strong" appears to be a characteristic of at least two messengers.
