Stigmata is a miracle ... and one Saint had apparitions, biolocation and stigmata, and that is Padre Pio, the following account may be a little long but wonderful to witness :
PADRE PIO (d. 1968), the only priest to bear the Wounds of Our Lord, experienced many mystical favors, not the least of which was bilocation, which he first experienced while he was still a divinity student at San’Elia a Pianisi. The archives of the friary of Santa Maria delle Grazie at San Giovanni Rotondo preserve the original handwritten pages in which the holy student explains what happened. Several days ago I had an extraordinary experience. Around 11:00 p.m. on January 18, 1905, Fra Anastasio and I were in the choir when suddenly I found myself far away in a wealthy home where the father was dying while a child was being born. Then there appeared to me the Most Blessed Virgin Mary who said to me: “I am entrusting this child to you . . . I want you to work with her because one day I wish to adorn myself with her.” I answered, “How is this possible, since I am still a mere divinity student and do not yet know whether I will one day have the fortune and joy of being a priest? And even if I become a priest, how can I take care of this child, since I am so far away?” The Madonna said, “Do not doubt. She will come to you, but first you will meet her at St. Peter’s in Rome.” After that, I found myself again in the choir.
The dying man was Giovanni Battista Rizzani, a fervent Mason who refused to be baptized. At the same time that his wife, Leonilde Rizzani, was praying at his bedside, Padre Pio was having “the extraordinary experience” at San’ Elia a Pianisi. Leonilde looked up and saw a young man wearing a Capuchin habit. As soon as she saw him, the young monk turned and left the room, but when she went to look for him he was nowhere to be found. She soon went into labor pains, gave birth to a baby girl and later returned to her husband’s bedside. A priest soon arrived, and over the objections of his Masonic friends who did not want a priest to minister to him, the dying man looked at the priest and said, “My God, my God. Forgive me!” and died within a few hours. This took place in 1905. After her husband’s death, Leonilde moved to Rome with her children. Seventeen years later, Giovanna, who was named for her father and was born the night of her father’s death, was in St. Peter’s Basilica with a friend when they encountered a young Capuchin who agreed to hear Giovanna’s confession. After confessing, Giovanna and her friend stood close by to speak again with the Capuchin priest, but a guard insisted they leave since the basilica was closed. He also added that no priest was in the basilica to hear confessions. An examination of the confessional by the guard left the two young women confused, since the Capuchin was not there and they had stood there waiting for him to leave and had not seen him.
Later that year Giovanna was shown a picture of Padre Pio, whom she promptly recognized as the priest who had heard her confession. This prompted her to visit San Giovanni Rotondo to see Padre Pio, and she did so with an aunt and several friends. When the Padre saw Giovanna, he smiled and exclaimed, “Why, Giovanna, I know you. You were born the night your father died.” He then revealed that her father had been saved because of her mother’s prayers and his intercession, that he was the priest who had heard her confession in St. Peter’s Basilica, and then told her about his strange experience when he had visited the room of her dying father. He also told her about the vision of Our Lady, who placed her in his charge. Padre Pio then invited her to come often to see him for spiritual direction. Giovanna told her mother all that had taken place, and by comparing Giovanna’s experience to those of her mother, both were convinced that Padre Pio had bilocated twice on their account, once to the death chamber and another time to the confessional. Padre Pio had told Giovanna that it was not in God’s plan for her to enter religious life. She later married and became the Marchioness Boschi of Cesena. She remained a devoted disciple of the holy Padre and gave a detailed deposition before the Archiepiscopal Curia of Manfredonia for the cause of beatification. The Curia compared her document to that written by Padre Pio in 1905 and noted the similarities. The document of Padre Pio was never read by Giovanna and the priest’s bilocations were known up to that time only by his superiors. But there were many other times when Padre Pio was seen at two places during the same time period, sometimes speaking, sometimes not. There were other times when only his presence was detected, or at other times there was the perfume of his stigmata which indicated his presence. A number of these bilocations are mentioned in the many biographies of this holy priest, which prove to be of great wonder and edification to those who study them.
