“Most attempts to discern the structure of Revelation have found it particularly difficult to see how chapters 12-14 fit into the overall structure. The beginning of chapter 12 seems an uncharacteristically abrupt fresh start, devoid of literary links with anything that precedes. The formula used in 12:1 and 12:3 (καὶ σημεῖον μέγα ὤφθη ἐν τῷ οὐρανῷ…καὶ ὤφθη ἀλλο σημεῖον ἐν τῷ οὐρανῷ…) is a quite fresh introductory formula, unlike any John has used before, and the two protagonists it introduces, the woman and the dragon, have not been mentioned in the book hitherto. Chapter 12 cannot be read as a continuation of the account of the seventh trumpet (11:15-19) because we know that the imagery of 11:19b describes the final judgment and concluded the account of the seventh seal in 8:1-5. There are not even the kinds of literary links backwards to preceding sections of the book which John provides elsewhere at major transitions which might otherwise seem like entirely fresh beginnings (4:1; 17:1; 21:9). It seems we must accept that the abrupt transition is intentional. John has made it abrupt precisely in order to create the impression of a fresh start. ¶The fresh start is required because the narrative of the woman and the dragon begins chronologically earlier than any previous part of his visionary narrative. It recalls the enmity between the woman and the serpent (Gen 3:15) and portrays the people of God (Israel) as mother of the Messiah. The story of the conflict between the dragon and the woman leads into an account of the contemporary conflict between the people of God (the church) and the enemies of God. This account ends with the vision of the conquerors of the beast triumphant in heaven (15:2-4), which is the upshot of the confrontation between the beast (chapter 13) and the followers of the Lamb (14:1-5). But if John has not integrated this section into the rest of his book at the beginning of the section, he has done so at its end. He links it to the account of the seven bowls which follows by the same technique of overlapping or interweaving as he had used to link the series of seal judgments to the series of trumpet judgments. He vision of the people of God triumphant over the beast in heaven (15:2-4) is sandwiched between the introduction of the seven angels with the seven last plagues (15:1) and the account of their preparation for pouring out the bowls on the earth (15:5-8). Moreover, the seven angels are introduced by a variation of the formula which has previously been used only to introduce the dragon and the woman at the beginning of chapter 12: καὶ εἰδον ἀλλο σημεῖον ἐν τῷ οὐρανῷ μέγα καί θαυμαστόν (15:1). This clearly makes the series of seven bowls a continuation of the narrative begun at the beginning of chapter 12. We have already noticed how 15:5 echoes 11:19a and 16:17-20 expands 11:19b, making the seven bowls a fuller version of the seventh trumpet. This means that chapter 15 is the point where the narrative begun in chapter 12 with the dragon’s threat to the pregnant woman converges with the narrative begun in chapter 5 with the Lamb receiving the scroll in order ot open it. Both narratives reach a provisional conclusion in the sequence of seven bowls (pending a further conclusion in 19:11-21:8). The convergence of the two narratives is shown by the fact that the seven bowls, a sequence of judgments which continues and completes the two previous sequences of seven judgments, refers as the previous sequences had not, to the forces of opposition to God in the terms which have been introduced in chapters 12-14: those who had the mark of the beast and worshipped its image (16:2), the throne and the kingdom of the beast (16:10), the dragon, the beast and the false prophet (16:13), Babylon the great (16:19).
The main function of chapters 12-15 is to deal much more fully with the subject that was adumbrated in the two intercalations (7:1-17; 10:1-11:13): the people of God in their conflict with the forces opposed to God. The links with the two intercalations are thematic rather than structural, but it is worth noting the most important: the 144,000 (7:4) reappear in 14:1, the apocalyptic period of the church’s suffering and witness (11:2-3) appears in 12:6, 14; 13:5, the beast who appears very enigmatically in 11:7 is properly introduced in chapter 13, where he makes war on the saints and conquers them (13:7) as he had already in 11:7.”
