Pier Giorgio's plans were to work as a lay missionary once he was a qualified engineer and then to get married. It was not God's will for him, however, as he fell gravely ill with polio and died. His family were astonished at the thousands of people who lined the streets for his funeral, not realising how many people in the city had experienced his kindness. Devotion to him continued to grow as his friends gathered for a day of recollection each year on the anniversary of his death.
Pope John Paul II beatified him in 1990 and his tomb is in the Cathedral of Turin, the Church that houses the Shroud.
At the beatification, Blessed John Paul II said of Pier, “By his example he proclaims that a life lived in Christ’s Spirit, the Spirit of the Beatitudes, is “blessed”, and that only the person who becomes a “man or woman of the Beatitudes” can succeed in communicating love and peace to others. He repeats that it is really worth giving up everything to serve the Lord. He testifies that holiness is possible for everyone, and that only the revolution of charity can enkindle the hope of a better future in the hearts of people.”
