The Illness That Claimed His Life
In October 2006, Carlo developed what appeared to be a common illness. Within a short time, his health declined rapidly, and doctors diagnosed him with acute promyelocytic leukemia, a condition known for its sudden onset and severity. Despite modern treatment options, the disease overwhelmed his body in just days.
He was admitted to a hospital near Milan, where his condition worsened. Complications included internal bleeding, which eventually caused him to slip into a coma. On October 12, 2006, Carlo Acutis died at 6:45 p.m., surrounded by prayer and the comfort of his family.
His Faith in the Final Hours
Even during intense suffering, Carlo demonstrated remarkable spiritual strength. He told his family and caregivers that he wanted to offer his pain for the Pope and for the Catholic Church. Those who were with him remember how he remained calm, encouraging his mother not to fear death, and reminding her that for believers, death is a passage into eternal life.
These words and actions left a deep impression, showing maturity far beyond his years. His peaceful acceptance of death became one of the most powerful testimonies of his short life.
From Tragedy to Canonization
Though his earthly life ended early, Carlo’s story only grew in significance. His deep devotion to the Eucharist and his passion for using technology to share faith made him stand out in modern times. He created an online catalog of Eucharistic miracles, showing how the internet could be used as a tool for evangelization.
In 2013, his cause for sainthood officially began. By 2018, he was declared Venerable, and in 2020, he was beatified following the recognition of a miracle attributed to him. Finally, on September 7, 2025, Carlo Acutis was canonized in Rome, becoming the first millennial saint in the Catholic Church.
