He went to the old church at San Damiano to pray, during which he heard Christ on the Cross say to him "Francis, repair my church." Taking this to mean repairing the building of San Damiano, he went to his father's shop and took some of the fine fabrics, selling them on the street so he could give the money to the church.
His father, Pietro, was furious. He took Francis to the bishop in the town square, accusing Francis of theft and demanding that he be forced to repay for the cloth he took. The bishop took Pietro's side and told Francis to return the money and not worry, because "God would provide." Francis not only gave his father the money, but right there in the town square he divested himself of his clothing (since it had come from his father), stripping down to just a hair shirt he had been wearing. He declared "Pietro Bernardone is no longer my father. From now on I can say with complete freedom, 'Our Father who art in heaven.'"
He walked away from town to live in the woods, a hermit with nothing. He later begged people to bring him stones and started to rebuild the crumbling San Damiano himself. He started to preach openly about returning to God and obeying the Church. People started to listen. Then they started to adopt his lifestyle, wanting to live simply, rejecting shelter and money. They slept in the open and begged for food.
Now that he had followers, Francis became concerned about the responsibilities of leadership. He now had to think about how his actions were influencing others. To do that, he had to think more deliberately about what his actions should be. He decided to open the Bible randomly and take its advice. He opened it in three places, and his inspiration formed the basis for his life and the Order he reluctantly founded. The first steps on the path to the Franciscans were taken. We will see how that turned out next.
