The meaning of the name he chose should not be underestimated. Cardinal Bergoglio is a Jesuit and the Jesuits were founded by St. Ignatius Loyola, who said he wanted to be like St. Francis of Assisi.
One of the most famous moments in St. Francis’s life is the day he was passing by the church of St. Damiano. It was old and near collapse. From St. Bonaventure’s “Life of Francis of Assisi”: “Inspired by the Spirit, he went inside to pray. Kneeling before an image of the Crucified, he was filled with great fervor and consolation. . . . While his tear-filled eyes were gazing at the Lord’s cross, he heard with his bodily ears a voice coming from the cross, telling him three times: ‘Francis, go and repair my house which, as you see, is falling into ruin.'” Francis was amazed “at the sound of this astonishing voice, since he was alone in the church.” He set himself to obeying the command.
