Book excerpt: This volume unpacks the psychological insights found in the writings of three early monks--Evagrius Ponticus (fourth century), John Cassian (fifth century), and Gregory the Great (sixth century)--to help us appreciate the relevance of these monastic writers and apply their wisdom to our own spiritual and psychological well-being. The book addresses each of the seven deadly sins, offering practical guidance from the early monastic tradition for overcoming these dangerous passions. As Dennis Okholm introduces key monastic figures, literature, and thought of the early church, he relates early Christian writings to modern studies in psychology. He shows how ancient monks often anticipated the insights of contemporary psychology and sociology, exploring, for example, how their discussions of gluttony compare with current discussions regarding eating disorders. This book will appeal to readers interested in spirituality, early monastic resources, and ancient wisdom for human flourishing, as well as students of spirituality and spiritual formation.
