Pope Francis created 10 new saints on Sunday, rallying from knee pain that has forced him to use a wheelchair to preside over the first canonization ceremony at the Vatican in over two years. Francis stood for a long period at the start to greet priests concelebrating the Mass, presided over the nearly two-hour ceremony and then stood and walked for a good 15 minutes after it ended to greet dozens of cardinals and bishops. Vatican cameras lingered on the scene as if to showcase the pope's mobility and refute speculation about his health and the future of his pontificate.
