Carlos Acutis, an Italian teenager and the first millennial to be beatified, was known for his devotion to the Eucharist and passion for technology, creating the website 'Eucharistic Miracles of the World'. Despite his brief life ending at age 15 from leukemia, he inspired many through his faith, charity work, and advocacy for marginalized individuals. His legacy continues as Pope Francis cites him as a role model for young people navigating modern challenges.
