Carlo Acutis, the first millennial saint, will be canonized on Sunday at the Vatican. Known as "God's influencer," Acutis, who died of leukemia at 15, used the internet to catalogue eucharistic miracles. His sainthood has inspired global devotion, with pilgrims visiting his tomb in Assisi and requesting miracles online. His rapid canonization, just 17 years after his death, is attributed to his digital outreach and the Church's efforts to engage younger generations. Miracles attributed to his intercession, including the healing of a Brazilian boy and a Costa Rican woman, solidified his canonization.
