Except for the Vatican, St. Anthony’s Chapel in Pittsburgh, Pennsylvania, has the largest collection of sacred relics of the Catholic Church. On the outside, it’s a small chapel that blends into the drab, working-class neighborhood surrounding it. But inside, there are over 5,000 relics, most of which are first or second class, meaning they were the body parts or possessions of saints. The collection was amassed by Father Suitbert Godfrey Mollinger, popularly known in the late 1800s as the “healing priest,” who practiced a combination of faith healing and medicine. Neither St. Anthony’s nor Father Mollinger is well known today.
