Prophecy of Malachy says city of seven hills will be destroyed, the book of revelation also says a city will be destroyed and is all related to the harlot who is the ROMAN Catholic Church. She will burn.

"And the woman was arrayed in purple and scarlet colour, and decked with gold and precious stones and pearls, having a golden cup in her hand full of abominations and filthiness of her fornication: And upon her forehead was a name written, MYSTERY, BABYLON THE GREAT, THE MOTHER OF HARLOTS AND ABOMINATIONS OF THE EARTH. And I saw the woman drunken with the blood of the saints, and with the blood of the martyrs of Jesus: and when I saw her, I wondered with great admiration. And the angel said unto me, Wherefore didst thou marvel? I will tell thee the mystery of the woman, and of the beast that carrieth her, which hath the seven heads and ten horns. The beast that thou sawest was, and is not; and shall ascend out of the bottomless pit, and go into perdition: and they that dwell on the earth shall wonder, whose names were not written in the book of life from the foundation of the world, when they behold the beast that was, and is not, and yet is. And here is the mind which hath wisdom. The seven heads are seven mountains, on which the woman sitteth." -- (Revelation 17:4-9 KJV)



The Roman Catholic Church is responsible for MILLIONS of Christian martyrs.
