He's known as the patron saint of the internet, for using social media and technology to draw people to Jesus.

The soon-to-be millennial-era saint died at the young age of 15.

On Tuesday, a piece of his heart was on display at Mass in Bucktown.

At 7 p.m. Wednesday night, it will be at Christ Our Light Parish in Hegewisch.

Acutis' canonization was originally scheduled for April 27, but was postponed following the death of Pope Francis on April 21.
