The story

Matheus Lins Vianna was a Brazilian child from Campo Grande, Mato Grosso do Sul, diagnosed with annular pancreas, a rare congenital malformation that left him unable to eat normally and suffering constant vomiting.^{[2] [3]}

Catholic reports say that during a celebration in Campo Grande in 2013, he was brought to venerate a relic of Carlo Acutis. After touching the relic, he immediately asked for food and stopped vomiting, and later medical tests confirmed that the condition had resolved.^{[2] [3]} So the basic story is very simple: a child who normally could not keep food down suddenly became hungry and, according to the family and later church reports, did not return to the earlier pattern.

Open full graphic

Matheus Lins Vianna's file is unusually easy to follow: a child with a named congenital disorder, a 2013 relic-veneration event, a sudden reported change, and a later Vatican decree. Local explainer graphic

The Vatican formally recognized the miracle in May 2020, clearing the way for Carlo Acutis’ beatification later that year.^[1]

Public Vatican chronology Matheus’s case is unusually easy to picture because the Vatican sources keep repeating the same simple sequence: diagnosed congenital disorder, relic veneration, sudden hunger, later medical confirmation, then the 2020 decree.

That direct sequence is one reason this file is more accessible than many older canonization miracles, even though the full medical dossier still is not public.

Publicly documented case file

The public record for Matheus Lins Vianna is anchored by one Holy See decree and two Vatican News reports focused on the family and the local church in Campo Grande.^{[1] [2] [3]}

Those sources place the following in the file:

• a congenital pancreatic disorder diagnosed in early childhood^{[2] [3]}
• relic veneration during a 2013 celebration in Campo Grande^{[2] [3]}
• immediate cessation of vomiting and the return of appetite according to family testimony^[2]
• the decree of May 27, 2020 recognizing the miracle for Carlo Acutis’ beatification^[1]

Publicly documented chronology

The sequence usually reported

The two Vatican News features on the case give a stable outline of the event and its aftermath.^{[2] [3]}

• Matheus had severe feeding problems from early childhood because of annular pancreas.^[3]
• His mother, Luciana Lins Vianna, prayed insistently for Carlo Acutis’ intercession.^[2]
• During the 2013 celebration, Matheus kissed or touched the relic and later described the moment simply: “I kissed the relic and I was cured and felt very hungry.”^[2]
• Vatican News reported that once home he was able to eat without vomiting and that the healing was confirmed by medical examinations.^{[2] [3]}

The claim is simple, immediate, and tied to a condition that should not suddenly disappear during an ordinary parish celebration. That directness is one reason this case is easier to follow than many older miracle files.

Role in the Acutis cause

This was the miracle that opened the way to Carlo Acutis’ beatification.^[1] The case passed through the Vatican’s formal process for miracles in sainthood causes.

The official reporting states:

• the Vatican recognized the miracle in 2020^[1]
• the event was tied to Campo Grande and to relic veneration connected with Carlo Acutis^{[2] [3]}
• the healed condition was a specific congenital pancreatic disorder rather than a vague symptom cluster^[3]

What the public record includes

Canonization and beatification causes generate another stream of medically investigated healings. This page documents one example drawn from the Acutis cause. It is not mainly a shrine-devotion file. It is a sainthood-cause file built around one child, one diagnosed congenital disorder, one reported turning point, and one later Vatican decree.
