NASHVILLE, Tenn. (CNS) — Father Ryan High School theology teacher Brent Fernandez grows a garden at home, raises chickens, and rides his bicycle to school when he can. In the summer, he takes students to visit Bethlehem Farm in West Virginia, a Catholic intentional community where he once lived for two years. He is passionate about treading lightly on the earth and embracing a less consumer-driven lifestyle. “I’m not perfect, but I try to live sustainably as much as possible,” he said. On the June morning when Pope Francis’ encyclical “Laudato Si’, on Care for Our Common Home” was released, Fernandez “was like a teenager on the day their favorite band drops a new album.” He pored over it, immediately connecting with so much of what Pope Francis wrote about, formulating how he would incorporate the encyclical into his junior-level Catholic social teaching class at Father Ryan. Fernandez is one of many theology and science teachers at the three Catholic high schools in the Diocese of Nashville who will be incorporating the papal encyclical into their curriculum this school year.
