A 15-year-old computer whiz, Carlo Acutis, is being declared the first millennial saint Sunday. Acutis, who died in 2006 after an acute case of leukemia, has been dubbed “God’s Influencer” because of his savvy use of information technology to spread the Catholic faith. Acutis was born on May 3, 1991, in London to a wealthy, but not particularly observant Catholic family.
