And upon her forehead was a name written,.... As the high priest had on his mitre upon his forehead written, holiness to the Lord, Exodus 28:36 only a different inscription from that; the allusion is thought to be to harlots, who not only used to put their names over their doors, but some of them upon their foreheads, that all might know who they were; of which Mr. Daubuz has given proofs out of Seneca, Martial, Juvenal, and Petronius; and such might be said to have an whore's forehead indeed: and this is expressive of the openness and impudence of the church of Rome, in her idolatrous worship; she openly declares it, and pleads for it, and invites and ensnares persons to join with her in it: the name follows,

mystery, Babylon the great, the mother of harlots and abominations of the earth; her name is "mystery"; not the mystery of godliness, that she dislikes and opposes, but the mystery of iniquity; which is the name antichrist went by in the Apostle Paul's time, when he was but in embryo, 2 Thessalonians 2:7. Some reference may be had to the mystery of the Mass, in which the Papists pretend are the very body and blood of Christ; to their seven sacraments, for wherever almost they find the word mystery, they make a sacrament of that to which it is applied; and to their unwritten traditions, and the sense of the Scriptures, which are locked up in the pope's breast: and it is very remarkable what has been observed by some, that the word "mystery" was formerly upon the frontlet of the pope's mitre, and was removed by Pope Julius the Third, when it was observed that the Protestants made use of this passage of Scripture, and applied it to the Romish antichrist. Joseph Scaliger l affirms, that he saw mitres at Rome with this inscription on them. Though others think that this is not any part of the name, but only signifies that this woman was, in a mysterious or mystical sense, called Babylon, c. just as the great city is spiritually called Sodom and Egypt, Revelation 11:8 but to me it seems to be a part of the name, as well as what follows, "Babylon the great" that is, the great city, Revelation 14:8 by which name the church of Rome may well be called, because of the signification of it, confusion, Genesis 11:9 its doctrine and worship being a confused mixture of Paganism, Judaism, and Christianity; and because of the pride and haughtiness of it, its tyranny and cruelty, and its sorceries and idolatry; see Isaiah 14:12.

And the mother of harlots, of all antichristian states and kingdoms; and is different from the heavenly Jerusalem, the Gospel church, which is the mother of true believers, Galatians 4:26 or the "mother of fornications": as some copies read, and the Vulgate Latin and eastern versions render it; that is, the author and encourager of them, as the church of Rome has been; of corporeal fornication, by commanding celibacy, and forbidding marriage to priests, and setting up of brothel houses; and of spiritual fornication or idolatry, everywhere required and encouraged by it: and of "the abominations of the earth"; of abominable doctrines and practices; all manner of wickedness that is to be found in the earth, as murder, adultery, sodomy, perjury, &c. these, with everything that is vile and wicked, are practised and connived at by her.

l In Scaligeran.

And upon her forehead - In a circlet around her forehead. That is, it was made prominent and public, as if written on the forehead in blazing capitals. In Revelation 13:1 it is said that “the name of blasphemy” was written on the “heads” of the beast. The meaning in both places is substantially the same, that it was prominent, and unmistakable. See the notes on that verse. Compare the note on Revelation 14:1.

Was a name written - A title, or something that would properly indicate her character.

Mystery - It is proper to remark that there is nothing in the original as written by John, so far as now known, that corresponded with what is implied in placing this inscription in capital letters; and the same remark may be made of the “title” or inscription that was placed over the head of the Saviour on the cross, Matthew 27:37; Mark 15:26; Luke 23:38; John 19:19. Our translators have adopted this form, apparently for the sole purpose of denoting that it was an inscription or title. On the meaning of the word “mystery,” see the notes on 1 Corinthians 2:7. Compare the notes on 1 Timothy 3:16. Here it seems to be used to denote that there was something hidden, obscure, or enigmatical, under the title adopted; that is, the word “Babylon,” and the word “mother,” were symbolical. Our translators have printed and pointed the word “mystery” as if it were part of the inscription. It would probably be better to regard it as referring to the inscription, thus: “a name was written - a mysterious name, to wit, Babylon,” etc. Or, “a name was written mysteriously.” According to this, it would mean, not that there was any wonderful “mystery” about the thing itself, whatever might be true on that point, but that the name was enigmatical or symbolical; or that there was something hidden or concealed under the name. It was not to be literally understood.

Babylon the great - papal Rome, the nominal head of the Christian world, as Babylon had been of the pagan world. See the notes on Revelation 14:8.

The mother of harlots -

1. Of that spiritual apostasy from God which, in the language of the prophets, might be called adultery. See the notes on Revelation 14:8.
2. The promoter of lewdness by her institutions. See the notes on Revelation 9:21. In both these senses, there never was a more expressive or appropriate title than the one here employed.

And abominations of the earth - Abominable things that prevail on the earth, Revelation 17:4. Compare the notes on Revelation 9:20-21.
