Pope Leo will canonize Blessed Carlo Acutis, the first millennial saint, on September 7th in St. Peter's Square. Acutis, a British-born Italian who died of leukemia at 15, used his tech skills to spread his faith. His canonization follows the confirmation of two miracles attributed to his intercession: the healing of a Brazilian boy and a Costa Rican girl. The ceremony also includes the canonization of Pier Giorgio Frassati. This is Pope Leo's first canonization.
