It is spiritually styled Babylon; for it is as much a city of confusion as was the original Babylon when the language of mankind was confounded in the days of Nimrod.

...She is styled "Mystery," because she is the embodiment of that "Mystery of Iniquity," which Paul says, was working at the time he was writing (2 Thess. ii. 7).

Scaliger testifies that "Mystery" was once worn as an inscription on the Pope's tiara; but afterwards removed by Julius III. The term "Mother," as applied to the Great City in its ecclesiastical relations is recognized by all. As Jerusalem is the Mother of all the Saints; so Rome is the Mother of all their enemies -- "Romana Ecclesia," says the Council of Trent, "quae, omnium Ecclesiarum Mater est et Magistra" -- The Roman Church, which is the MOTHER and MISTRESS of all churches.

The Popes themselves seem determined that there shall be no lack of evidence to prove the identity of the ecclesiastical polity of which they are the deified head, with the apocalyptical Great City Babylon.

On occasion of the last Jubilee a medal was struck, a copy of which is given in Elliott. It is the size of a quarter of a dollar; on one face, is the effigy of Leo XII; and on the obverse, a Woman, symbolizing the Roman Church, sitting on a globe, with rays of glory on her head, a cross in the left hand, and a cup, signed with a cross in its mouth, in her extended right hand, as if presenting it to be drunk. Beneath her is the date, and around her face the legend "Sedet super Universam. Anno Iubi. MDCCCXXV." -- She sits upon the world.

In the year of Jubilee, 1825 -- (Apoc. xvii. 4,15). Yes, she sits upon the world, or "upon many waters," the shameless strumpet of the unmeasured court; and like certain notorious prostitutes of pagan times, bears her ignoble name upon her forehead.*

[* "In allusion," says Bp. Newton, of whose church she is Mother, "to the practice of some notorious prostitutes who had their names written on a label upon their foreheads, as we may collect from ancient authors. Thus Seneca says, Nomen tuum pepenit in fronte: pretia stupri accepisti -- 'Thy name hath hung upon thy forehead: thou hast received the reward of thy dishonour.'"]

But the Great City is not only spiritually styled Babylon because of the confusion of spiritual speech that obtains among all the "Names and Denominations" of which it is ecclesiastically constituted; but because it is the modern development of the same power that existed in the days of the Chaldean Babylon; whose golden head, for the time being, was the Dynasty of Nebuchadnezzar: and because a similar fate awaits her.

It is, I say, the same power, only modified by time and circumstances. I do not say by place as well as by time and circumstances; for, when the Gogue of Ezekiel shall have attained to the full extent of his latter day dominion, much of Babylonia, even more than he now possesses, will be his. He will be, in the full manifestation of his power, the very apex of the Little Horn of the Goat -- the Hellenistic Horn of the Great City, which even now includes the site of Babylon in its domain.
