Padre Pio was canonized upon the recognition of a miracle attributed to him. The miracle was the healing of a nun, Sister Marie Rose, who had been blind for over 20 years. After praying to Padre Pio, Sister Marie Rose regained her sight. The miracle was approved by the Vatican in 1999, and Padre Pio was canonized in 2002.
