Carlo Acutis, who died of leukemia at the age of 15 in 2006, was beatified on Saturday in the Italian city of Assisi.
Beatification is the penultimate step in the holiness process and means that the candidate can be called “blessed” and that a miracle has been confirmed in his name.
Another miracle is needed for canonization, the formal act of declaring someone a saint.
The teenager used his taste for technology to create a website tracing the history of Eucharistic miracles, which has been used by more than 10,000 parishes around the world, the Vatican said.
The Vatican has announced that Acutis will be beatified following claims that he healed a Brazilian boy suffering from a rare disease through intercession.
Acutis was born in London to Italian parents before the family moved to Milan, where he lived until his death, the Vatican said.
Acutis, described by the Vatican as a “computer genius with a love for the Eucharist” is believed to be the youngest of the beatified contemporaries.
