‏ Revelation of John 17:5

5 And a name was written upon her forehead: Mystery, Babylon the great, the mother of the fornications and the abominations of the earth. ^{▼▼17:5 A mystery: That is, a secret; because what follows of the name and title of the great harlot is to be taken in a mystical sense.(Challoner)
,} ^{▼▼17:5 Babylon: Either the city of the devil in general; or, if this place be to be understood of any particular city, pagan Rome, which then and for three hundred years persecuted the church; and was the principal seat both of empire and idolatry.(Challoner)}
