Good luck getting through an entire day without experiencing the impact of Catholicism. Woken up by an alarm or checked the time? The mechanical clock was invented in the tenth century by a monk who became pope. A bowl of cereal for breakfast? Your milk is safe thanks to Louis Pasteur, a devout Catholic whose research was driven by a love of God and humanity. Knock on wood? It’s actually an ancient Catholic practice invoking the power of the Cross when facing trouble or danger.

Each entry in 150 People, Places, and Things You Never Knew Were Catholic is rich with detail and nuance. Here are Catholic stories full of drama, decisions, and inspiration.

The fruits of our Catholic Faith are all around us, and the ways in which the Church has shaped history and the secular world can be found in science, art, pop culture, sports, and more.

You’ll discover things you never knew — and come away with inspiration for how you, too, can impact the world.
