Two 20th-century popes who changed the course of the Catholic Church became saints Sunday as Pope Francis honored John XXIII and John Paul II.
An estimated 800,000 people — many of them from John Paul II's native Poland — filled St. Peter's, the streets around it and bridges over the Tiber River, a huge turnout but only half the size of the crowd that came out for John Paul's 2011 beatification.
