The Pope Who Quit

What a character! Let's let Sister Mary Martha tells us about it (she just finished reading the book):

"Peter Morrone, who became Celestine V had been a very charismatic and deeply holy monk who founded monasteries and oratorios and the Celestine order of monks and had many, many followers because he walked the walk.  He wore no shoes and a ragged robe. He lived in a cave by himself,up in the mountains. St. John the Baptist was his hero.
Back then there were only about 12 Cardinals around to elect a Pope.  They'd all go off to some really nice place and take their sweet time because the food and wine was terrific. That's why they finally got locked in a room that they couldn't leave until they elected someone, called a papal conclave.  
This time they dithered for two years,  and still couldn't come up with a good candidate.  How in the world did they come up with the idea of a man who lived far away in a cave? Peter Morrone had written them a letter about their foot dragging and said that their behavior would incur the wrath of God. It caused one of the Cardinals to exclaim that Peter was the best choice.
Then they all traveled over to the cave on the mountain where Peter lived. He refused the robes and the crown and the Vatican. He had his coronation procession on a donkey and lived in a castle of Charles II.  He was Pope for five months. During the five months he became more and more reclusive, eventually building a cell for himself in the basement where he signed anything anyone put in front of him. 
But ironically, two of his papal decrees are still with us. One is that the Pope will be elected by locking the cardinals in a room until they elect somebody. The other, that a Pope should be allowed to abdicate."
