Justine Callis was raised in a Christian home, and became a successful gymnast. Her athletic pursuits led her to Arizona, where she plugged into an Evangelical megachurch and her faith began to grow. She also worked in Evangelical campus ministry at Arizona State, where she was coaching.

When she met Catholics who were on fire for their faith, it shocked her; she’d thought Catholicism was a “dead religion.” She began to explore Catholicism, especially the doctrine of the Eucharist and the concept of a Magisterium, and over the course of two years of prayer and study, discerned that God was calling her to become Catholic.
