17:9 seven mountains. Many commentators have alleged the “seven heads” to be the “seven-hilled city” of Rome, hence deducing the great harlot to be the Roman Catholic Church. Such identification is impossible, however. Many cities have seven hills, and Rome actually has more. Besides, the Catholic Church does not sit on the hills of Rome, for its churches are all over the world and its headquarters are in Vatican City. Furthermore, a “hill” (Greek bounos) is not a “mountain” (Greek oros). The seven “mountains” are quite clearly expounded in the next verse as seven kings and/or kingdoms.
