I looked around me and marveled at this ninety-year-old man from whose hand had sprung everything I could see. He had carved the door, made the stained-glass windows and every other object in sight. Pacem in Terris, I realized, was one man’s act of artistic faith: a work of art outside the parameters of the art world, and also a religious statement unconfined by any religion.
