The Vatican has announced that the first millennial saint will be canonized in September.

Pope Leo XIV made an announcement during a meeting with cardinals that Carlo Acutis will be inscribed into the Book of Saints on September 7.

Acutis died at the age of 15 in Northern Italy after a short bout with leukemia in 2006, according to the Associated Press.

Before Pope Francis’s death on April 21, Acutis was set to be canonized on April 27 during the Vatican’s Jubilee of Teenagers.

The first intercession by Acutis came from his own mother, Antonia, who told Fox News that it came four years after his death.

“When Carlo died, I was 39 years old, and then I started to try to have other children. I said, ‘I’m still young, maybe I can try, no?’ [But] the children didn’t arrive. Then I had started on my practice to adopt a child, but in Italy, it’s very difficult… I had lost all my hopes to have children by myself,” she explained. “Once I dreamed about Carlo, he told me, ‘listen, you will become, again, a mother. Don’t worry.’ And, one month after, I became pregnant.”

According to the National Catholic Register, the Vatican has recognized a second miracle by intercession on May 23, 2024.

The miracle involved a 21-year-old Costa Rican woman named Valeria Valverde.

Valverde sustained a serious brain injury in a bicycle accident while residing in Florence, Italy in 2022. Valverde was not expected to survive the injury.

However, she made a full recovery after her mother visited Acutis’s tomb and prayed for his intercession, according to the National Catholic Register.

Acutis’s tomb, which is located in Assisi, has been visited frequently by Catholics, most notably younger Catholics.

Acutis will be joined by the blessed Pier Giorgio Frassati when he is inscribed in the book of saints.
