An early-aughts blog is probably not where you’d expect to find the next Mother Teresa, but that is where Carlo Acutis — soon to become the first millennial saint in the Catholic church — made a name for himself documenting miracles.

The Holy See said Thursday that Pope Francis has recognized a second miracle linked to Acutis, paving the way for his canonization — the final step in a process that can sometimes take decades. It will place the online evangelizer — who died in 2006 from leukemia at age 15 — among thousands of saints recognized by the church.
