The real name of St Celestine was Pietro Da Morrone or Pietro Del Murrone, (born 1215, Isernia?, Kingdom of the Two Sicilies—died May 19, 1296, near Ferentino, Papal States; canonized May 5, 1313; feast day May 19), pope from July 5 to Dec. 13, 1294, the first pontiff to abdicate. He founded the Celestine order.
When the father of this Italian saint died, his good mother brought up her twelve children well, even though they were very poor. "Oh, if I could only have the joy of seeing one of you become a saint!" she use to say. Once when she asked as usual, "which one of you is going to become a saint?" little Peter (who was to become Pope Celestine V) answered with all his heart, "Me, mama! I'll become a saint!" And he did.
When he was twenty, Peter became a hermit and spent his days praying and reading the Holy Bible. If he was not praying or reading, he would copy books or do some hard work so that the devil would not find him doing nothing, and tempt him. Because other hermits kept coming to him and begging him to guide them, he started a new Order.
Peter was an old monk, eighty-four years of age when he was made Pope. It came about in a very unusual way. For two years, there had been no Pope, because the Cardinals could not decide whom to choose. St. Peter sent them a message to decide quickly, for God was not pleased at the long delay. Then and there, they chose the holy old hermit himself! Poor Peter wept when he heard the news, but he sorrowfully accepted and took the name Celestine V.
