Notre Dame celebrated the Feast of Saint Francis on Friday by blessing bikes.
Saint Francis is the patron saint of the environment, so the university held a special Mass and blessed bikes that people brought to the South Quad.
Parents used this as a way to teach their kids about Saint Francis.
"He was a big proponent of nature and God's creations and keeping our Earth beautiful," said Christine Green. "By using our bikes, that's one way we're definitely keeping less of a footprint on the Earth. So, we try to do that. And it's a great way for the kids to understand a little more about Saint Francis and his mission and again keeping God's Earth beautiful."
Notre Dame's Feast of Saint Francis program started in 2010 after the university held a conference on sustainability in 2009.
