Revelation 17:16

Christ, who teaches and shows that the people of the Gentiles were coming into that place that the Jews had lost and that we were arriving afterward through the merit of faith, made wine from water, that is, he showed that the people of the Gentiles rather would resort together and come to the nuptials of Christ and of his church when the Jews were leaving. For the divine Scripture declares in the Apocalypse that the waters signify the peoples, saying, “The waters that you saw on which that harlot sits are peoples and crowds and nations of the heathen and tongues.” We perceive that this is actually also contained in the sacrament of the chalice. For because Christ, who bore our sins, also bore us all, we see that people are signified in the water, but in the wine the blood of Christ is shown. But when water is mixed with wine in the chalice, the people are united to Christ, and the multitude of the believers is bound and joined to him in whom they believe. This association and mingling of water and wine are so mixed in the chalice of the Lord that the mixture cannot mutually be separated. Whence nothing can separate the church, that is, the multitude established faithfully and firmly in the church, persevering in that which it has believed, from Christ as long as it clings and remains in undivided love. But thus, in the consecrating of the chalice of the Lord, water alone cannot be offered, nor can wine alone. For if anyone offers wine alone, the blood of Christ begins to be without us. If, in truth, the water is alone, the people begin to be without Christ. But when both are mixed and, in the union, are joined to each other and mingled together, then the spiritual and heavenly sacrament is completed.

"And the beast which thou sawest is of the seven." Since before those kings Nero reigned.

"And he is the eighth." He says only when this beast shall come, reckon it the eighth place, since in that is the completion. He added:-

"And shall go into perdition." For that ten kings received royal power when he shall move from the east, he says. He shall be sent from the city of Rome with his armies. And Daniel sets forth the ten horns and the ten diadems. And that these are eradicated from the former ones,-that is, that three of the principal leaders are killed by Antichrist: that the other seven give him honour and wisdom and power, of whom he says:-

"These shall hate the whore, to wit, the city, and shall burn her flesh with fire." Now that one of the heads was, as it were, slain to death, and that the stroke of his death was directed, he speaks of Nero. For it is plain that when the cavalry sent by the senate was pursuing him, he himself cut his throat. Him therefore, when raised up, God will send as a worthy king, but worthy in such a way as the Jews merited. And since he is to have another name, He shall also appoint another name, that so the Jews may receive him as if he were the Christ. Says Daniel: "He shall not know the lust of women, although before he was most impure, and he shall know no God of his fathers: for he will not be able to seduce the people of the circumcision, unless he is a judge of the law." Finally, also, he will recall the saints, not to the worship of idols, but to undertake circumcision, and, if he is able, to seduce any; for he shall so conduct himself as to be called Christ by them. But that he rises again from hell, we have said above in the word of Isaiah: "Water shall nourish him, and hell hath increased him; "who, however, must come with name unchanged, and doings unchanged, as says the Spirit.

The harlot is the life of luxury that is lived by plunder and pleasures. It says that they would hate the harlot, for dissolute persons who are also proud, lustful and arrogant not only persecute the saints, but they also hold themselves in hatred. And in another way do those hate themselves in whom the word of Scripture is fulfilled, “Those who love iniquity hate their own soul.” “And they will make her desolate and naked.” Through the wrath of God and his just judgment by which they are abandoned by him, they themselves will make the world a desert, since they have been given over to it and use it unrighteously. “And they will devour her flesh.” This is so, because as the apostle says, “They will bite and eat one another.”

But how will Rome be laid waste by the kings? For we understood that this was indicated through the Revelation. Perhaps to them she will be fought over as a royal city and stronghold and populous and collecting tributes. Therefore in the war concerning her she is forced to suffer as the prize of victory laid up for all, being burned and laid waste.

What the apostle said, “God gave them up to a base mind to do what they ought not,” that is also now said. For God has placed in their hearts to do that which is pleasing to him. Righteousness is pleasing to God, through which we know that retribution is visited upon the impious. Moreover, [it is according to God’s will] that they who have given their kingdom to the beast pay their just penalties with the beast, until the words of God be fulfilled, which, to be sure, consist of justice and mercy. For “all the paths of the Lord are mercy and truth.”

This woman is the very one who was given over to the corruptions of flesh and blood and who had prospered through the power of the earthly kingdom. And since she consists of those very kings over whom she is said to reign according to her habit, [the text] has divided the very same one into parts, as though separating a genus into its species, so that the words of the Lord will be fulfilled in the woman, in the city, in the kings, on the kings and on [the woman], when he redeems his own by his mercy and by his justice condemns the insolent.

Since the angel explained these things clearly, a more detailed explanation of them is superfluous. It is remarkable to me how the devil is both enemy and avenger. For he will work through the ten horns, who are guided by him, to oppose that lover of good and virtue, Christ our God, and to lay waste that populous city that has abandoned the divine laws and become servant to his pleasures, and like a bloodthirsty beast they will glut themselves on its blood. He will regard its conflagration as an occasion for rejoicing and the mutilation of human flesh as proper food, and he who always rejoices in duplicity will grant harmony to those ten apostate horns. That which continues makes very clear that the woman who was seen is the great city that exercises power over the kings of the earth, and the sufferings of that power that is ruling during those times is prophesied. From these trials the beneficent God will redeem us and enlist us in the heavenly city, namely, in the Jerusalem above. In this city “he will be everything to everyone,” as the apostle says, “when he shall destroy every rule,” clearly every apostate rule, “and every authority and power.” In addition, he will recline with and serve those who have served him here faithfully and wisely, that is, he will give them the enjoyment of the eternal blessings that have been “prepared from the foundation of the world.” Of this bliss may also we be found worthy in Christ, the Savior and Redeemer of our souls, with whom be glory and power to the Father, together with the Holy Spirit forever and ever. Amen.

And the ten horns which you saw, etc. The glory of the world, which they now embrace with wanton love, they will begin to detest with great hatred when they see themselves condemned at the end by the Lamb's victory. It can also be understood in another way, whether it is that there are always quarrels among the proud, or that everyone who loves iniquity hates his own soul (Psalm 10).

And they will eat her flesh, etc. They will burn her, deprived of her usual luxuries, with the fires of hell.

And they will make her desolate and naked. For they themselves make the world desolate through the wrath of God, while they are devoted to it and use it unjustly.
