VATICAN CITY, VATICAN - 2016/02/06: Faithful gather in St. Peter's Square before the arrival of Pope Francis for an audience to the Padre Pio Prayer Groups at the Vatican. Padre Pio became famous for bearing the stigmata, which are the marks of Christ, for most of his life, thereby generating much interest and controversy. He was both beatified (1999) and canonized (2002) by Pope John Paul II. (Photo by Giuseppe Ciccia/Pacific Press/LightRocket via Getty Images)
