Carlo Acutis

Carlo Acutis was born on May 3, 1991, in London, where his Italian parents were temporarily living. He was raised in Milan, and from his earliest years showed an unusual spiritual seriousness that coexisted with an entirely ordinary boyhood. He played video games, loved soccer, kept a dog and a cat, and counted among his friends children from the margins of his neighborhood — the homeless, the elderly, the disabled — whom he visited and helped regularly.

He began attending daily Mass as a young child and spent time in Eucharistic Adoration each day, which he described as the source of everything. He said the Eucharist was his "highway to heaven." He received his First Communion at age seven, earlier than the standard age, after convincing his parish priest that he was ready.

He taught himself computer programming and web design. At eleven, he began cataloguing authenticated Eucharistic miracles from across the centuries — cases where the consecrated host or wine had undergone visible physical changes confirmed by Church investigation. He built a website, miracolieucaristici.org, that documented these cases with photographs, medical evidence, and sources. He later designed a traveling multimedia exhibition of the same material that has since been displayed in dozens of countries. He never sought recognition for it. He considered himself only a documentarian.

He was diagnosed with M3 acute promyelocytic leukemia on October 1, 2006. He died eleven days later, on October 12, in Monza. He was fifteen. His last words, according to his mother, were an expression of contentment — that he had given everything to God and kept nothing for himself.

His body was transferred to Assisi and is displayed in the crypt of the Sanctuary of the Spoliation. Unlike some saints whose bodies are displayed incorrupt, Carlo's body has undergone natural decomposition; the displayed figure wears a wax mask molded to resemble his living appearance — an Italian tradition also used for other beatified and canonized figures. He wears a tracksuit and sneakers. He was beatified there on October 10, 2020, by Cardinal Agostino Vallini. On September 7, 2025, Pope Leo XIV canonized him in Rome alongside Blessed Pier Giorgio Frassati. He is the first person born in the twentieth century's final decade to be declared a saint.
