In 590 AD, seven years before Augustine of Canterbury would venture over to Britain, St. Columban crossed the channel the other direction to Gaul. Columban was an Irish monk, a scholar of Bangor Abbey, that great center of monastic learning. With faithful companions, he set out on a mission to spread the Irish monastic way among the Franks of Gaul and (later) the Lombards of Italy. This way he encoded in a rule: The Rule of St. Columban. In this episode of Christian Humanist Profiles, David Grubbs interviews Fr. Terrence Kardong, noted Benedictine scholar and monk of Assumption Abbey in Richardton, ND, about his new book Saint Columban: His Life, Rule, and Legacy (Liturgical Press, 2017).
