There is a not so well known prophecy known as the prophecy of Pope Malachy or the prophecy of the Popes. According to this prophecy the next Pope will be the last Pope in history!
"...In 1139 St. Malachy went to Rome to give an account of the affairs of his diocese to the pope, Innocent II, who promised him two palliums for the metropolitan Sees of Armagh and Cashel. While at Rome, he received (according to the Abbé Cucherat) the strange vision of the future wherein was unfolded before his mind the long list of illustrious pontiffs who were to rule the Church until the end of time...."
What does this mean?
According to this prophecy there will be a succession of 112 popes from the first until the end of days. Our current Pope is the 111th. According to this prophecy the next Pope will be an individual referred to as "Peter the Roman" and will be the last Pope.

Be sure to read the fine print (as usual)
"...it should be noted that some commentators over the centuries have pointed out that there is nothing that says there will be no popes between Gloria Olivæ and Petrus Romanus. It may be that there will be a long line of popes between them!"
