What is a monk? The word evokes the image of a man robed and cowled, tonsured in the West, bearded in the East. It recalls the architecture of the monastery, the chanting of the Daily Office, the monastic rules and vows. Defined thus, monasticism is for the disciplined and committed few. In fact, in many streams of Christianity, those few are none at all. But what if those external things—the robes, rites, and rules—don’t make the monk? What if the essence of monasticism is something internal, something akin to the Gospel faith in which all Christians stand equal? In this episode of Christian Humanist Profiles, David Grubbs interviews Dr. Greg Peters, associate professor of medieval and spiritual theology in the Torrey Honors Institute at Biola University, and author of The Monkhood of All Believers: The Monastic Foundation of Christian Spirituality (Baker Academic, 2018).
