The 15-year-old Italian teenager Carlo Acutis was canonized as a saint of the Catholic Church by Pope Leo XIV at the Vatican. Acutis died of leukemia in 2006 at age 15 and became known as God’s “influencer.” Crowds gathered from Saturday morning in St. Peter’s Square to watch the ceremony, with giant screens set up for the occasion.

Thus, Acutis became the first saint of the Catholic Church belonging to the millennial generation.

The 15-year-old, who used his computer skills to create websites with religious content, has inspired thousands of young Catholics worldwide. His mother, Antonia Salzano, told Reuters that her son’s appeal was based on the fact that he was a normal child like others, but his uniqueness was that he prioritized God and used his talent to spread the Gospel. “He wanted to help people have more faith, to understand that there is life after death,” she said characteristically.

The canonization ceremony was originally scheduled for April but was postponed following the death of Pope Francis. Pope Leo, who was elected in May, presided over his first canonization ceremony today.
Acutis’ body is housed in the city of Assisi, as was his wish, and his tomb has become an important pilgrimage site. There he is displayed with a wax figure depicting him wearing a tracksuit, jeans, and sneakers.
Besides Acutis, the Pope also canonized Pier Giorgio Frassati, a young Italian who died of polio in the 1920s and was known for his charitable work.
