On September 7, 2025, Pope Leo XIV canonized Carlo Acutis, a London-born teenager who died of leukemia in 2006, during a Mass at St. Peter’s Square attended by tens of thousands. Acutis, known as “God’s Influencer,” used technology to document Eucharistic miracles and is hailed as a relatable role model for young Catholics. The ceremony also canonized Pier Giorgio Frassati, noted for his charity.
