Pope Leo XIV is set to declare a 15-year-old computer whiz, Carlo Acutis, the first millennial saint on Sunday, giving the next generation of Catholics a relatable, modern-day role model who used technology to spread the faith and earn the nickname “God’s influencer.” The first saint-making ceremony of Leo's pontificate drew hundreds of thousands of people and was also set to canonize another popular Italian figure who died young, Pier Giorgio Frassati. Both ceremonies were scheduled for earlier this year, but were postponed following Pope Francis’ death in April. Francis fervently willed the Acutis sainthood case forward, convinced that the church needed someone like him to attract young Catholics to the faith while addressing the promises and perils of the digital age.
