What is the mystery of the scarlet woman and the beast, and how does the Lamb achieve victory over their worldly confederacy?

One of the seven angels bearing the bowls of judgment approaches John, summoning him into the wilderness to witness the condemnation of the notorious courtesan seated upon expansive waters. Earthly sovereigns have engaged in spiritual adultery with her, while terrestrial populations have become intoxicated drinking the wine of her unchaste indulgences. Carried away in spirit, the prophet observes a woman mounted upon a scarlet-hued monster covered with blasphemous inscriptions, possessing seven heads and ten horns. She appears regally attired in royal purple and crimson, adorned with gold, glittering gems, and precious pearls, while holding aloft a golden goblet filled with the foul abominations of her corrupting influence. Upon her brow rests a cryptic title: a mystery denoting the great city Babylon, the mother of worldwide fornications and abhorrent defilements. Bishop Challoner notes that the term mystery signifies a hidden mystical meaning, and that Babylon represents either the kingdom of the devil generally or pagan Rome specifically, which for three centuries violently persecuted the faithful as the capital of empire and idolatrous religion. John watches in stunned bewilderment as the woman reels in drunken ecstasy from the shed blood of consecrated saints and martyrs of Jesus.

Observing John's amazement, the celestial guide explains the hidden significance of both the woman and the scarlet creature sustaining her. The angel explains that this beast once existed, currently is not, yet will ascend out of the abyssal pit before proceeding toward final perdition, causing earthbound souls omitted from the book of life to marvel in wonder. Bishop Challoner suggests that the beast may signify the tyrannical power of the adversary, drastically curtailed by the advent of Christ yet destined to exert ferocious malice during the reign of Antichrist. The seven heads represent seven summits upon which the courtesan reclines, as well as seven imperial sovereigns. Five dynasties have already fallen, one holds present sway, and a seventh has not yet arrived, whose eventual reign will prove brief. The creature itself embodies an eighth sovereign power derived from the seven, uniting their wicked tyranny under demonic impulse before plunging into irrevocable doom.

The angel further discloses that the ten horns correspond to ten confederate kings who have not yet received formal kingdoms, but will assume temporary royal authority one hour after the beast. Sharing a unified intent, they surrender their military might to the monster and wage war against the Lamb. Yet the Lamb conquers them, because He is the supreme Lord of lords and King of kings, accompanied by followers who are chosen, called, and faithful. The waters where the courtesan sits are revealed as multifaceted nations, tribes, and language groups. Under divine providence, the ten confederate rulers develop fierce hatred toward the courtesan, stripping her garments, devouring her flesh, and burning her with fire to execute divine chastisement. As Bishop Challoner explains, these lesser monarchies, understood by some as Goths, Vandals, Huns and other nations that destroyed Rome’s empire, are described as instruments of God's sovereign retribution until every prophetic word reaches fulfillment, culminating in the downfall of that dominant capital governing earthly monarchs.
