NEW: Carlo Acutis, who died in 2006 at age 15, will be canonized as the first millennial Catholic saint this Sunday.
Acutis, who succumbed to leukemia, gained fame for documenting miracles online, earning the title "God's influencer."
"Carlo was an ordinary kid—playing, making friends, attending school. But his extraordinary trait was opening his heart to Jesus, placing Him first," his mother shared.
"He used his skills to share the Gospel, aiming to strengthen people's faith and remind them of the afterlife, showing we are pilgrims in this world."
Since his beatification in 2020, Acutis' body, displayed in Assisi, Italy, has drawn over 100,000 visitors annually.
