Pope Francis made an impromptu stop minutes after arriving at the Philadelphia airport this morning when he had his driver pull over so he could bless a 10-year-old boy with cerebral palsy, NBC Philadelphia reports. The pope leaned over a barricade and kissed Michael Keating, who uses a wheelchair. He also blessed others nearby, including a nun who drew his attention to Michael. The boy's mother thanked the pope through tears. KTRK reports the boy's father is the director of the marching band whose rendition of the theme from Rocky greeted the pope as he disembarked his plane. (More Pope Francis stories.)
