A man named Malachi Martin made a prophecy when he received a vision concerning all the future popes from his day.
According to his prophecy, only 2 popes remain until the "end" after John Paul II. After Benedict, the current pope, Malachi Martin describes the last pope as the following:
"Peter the Roman, who will nourish the sheep in many tribulations; when they are finished, the city of seven hills will be destroyed, and the dreadful judge will judge his people. The end."
