Mystery, Babylon the Great and the Mysteries and Roman Catholicism by G H Pember and published by Classics Publications.
Revelation 17 and 18 speak of the Babylon in both its religious and political aspects, and indicate in what manner God will deal with these two systems at the end time. Mystery Babylon The Great considers the vision of Babylon in the the light of both the Bible and history. Pember also shows how the Roman Church, which he believes to be prefigured by the harlot in Revelation 17, has derived much of its liturgy and practices from ancient pagan sources.
