This groundbreaking four-hour documentary series shares the journeys of Catholics, Evangelical Christians, Muslims, and Jews who have decided to enter the clergy. An in-depth exploration of religion in the U.S. from the perspective of its future leaders, The Calling begins with the subjects’ first steps across the thresholds of academia, follows them through years of study and training, and continues into their early practice as ordained religious professionals. The series includes Rob Pene, a Samoan American Christian rapper. The culturally diverse subjects offer an engaging portrait of how faith is lived in a modern and largely secular world. (Distributed on the PBS National Program Service on December 20–21, 2010.)
