Matheus Vianna & Valeria Valverde — St. Carlo Acutis

Two miracles were attributed to Carlo Acutis's intercession, leading to his beatification (2020) and canonization (2025).

Beatification miracle (2013). Matheus Vianna, a three-year-old boy from Campo Grande, Brazil, suffered from annular pancreas — a rare congenital condition in which the pancreas constricts the duodenum and prevents food from leaving the stomach. By age three, Matheus weighed only 20 pounds, was restricted to a liquid diet, and vomited constantly. Doctors concluded he needed surgery but feared he would not survive it.

On October 12, 2013 — exactly seven years after Carlo Acutis's death — Matheus attended Mass at the Parish of São Sebastião. Father Marcelo Tenorio had obtained a first-class relic of Carlo's clothing from his mother, Antonia Salzano. When Matheus touched the relic, he asked to "stop throwing up." He was immediately cured. On the way home, he asked for solid food — French fries, rice, beans, and steak — and ate normally without vomiting for the first time in his life.

Canonization miracle (2022). Valeria Valverde, a 21-year-old student from Costa Rica studying in Florence, Italy, suffered severe head trauma in a cycling accident on July 2, 2022. She required emergency craniotomy surgery to reduce intracranial pressure. Doctors told her family the situation was critical and she could die at any moment.

Six days after the accident, Valeria's mother Liliana traveled to Assisi and prayed at Carlo Acutis's tomb, leaving a written note requesting her daughter's healing. That same day, Valeria began breathing on her own. The following day, she recovered the use of her upper limbs and partially regained her speech. A CT scan revealed that the hemorrhagic right temporal cortical contusion in her brain had completely disappeared. Contrary to medical predictions of months of rehabilitation, Valeria spent only one week in physical therapy. Two months after her accident, she returned to Assisi with her mother to celebrate her complete recovery.

• Instant, medically documented cure of a congenital defect. Matheus Vianna's annular pancreas was confirmed by imaging and clinical examination. The condition does not resolve spontaneously — it is a structural malformation that requires surgical correction. His instant cure upon touching the relic, with immediate ability to eat solid food, had no medical explanation.

• Catastrophic brain injury with complete reversal. Valeria Valverde's hemorrhagic brain contusion was documented by CT scan before and after the healing. The complete disappearance of a traumatic brain lesion within days — without surgical intervention — contradicts established neurology.

• Temporal precision. Matheus's healing occurred on October 12, 2013 — the exact seventh anniversary of Carlo Acutis's death. Valeria's recovery began on the same day her mother prayed at Acutis's tomb in Assisi.

• Vatican medical and theological review. Both miracles underwent the full Vatican process: examination by the Consulta Medica (panel of independent physicians), review by the Theological Consultors, and final approval by Pope Francis. The beatification miracle was approved February 22, 2020. The canonization miracle was approved May 23, 2024.

• Carlo Acutis was canonized September 7, 2025 — the first millennial saint — alongside Pier Giorgio Frassati, confirming the Church's confidence in both miracles.
