Holy Knights? They were as combative as George, the dragon slayer, or Joan of Arc, brave like Romedius, who rode on a bear. Initially, they were soldiers of their earthly rulers, later dedicating themselves entirely to the service and obedience of their heavenly Lord, like Martin and Francis. Or they gave their lives for another, like Maximilian Kolbe, originally the founder of the Knights of the Immaculata. Throughout all times, people have felt within themselves the special fire of a calling. This book gathers six very different life stories from the beginnings of Christianity to the 20th century. In this unusual collection, knighthood and chivalric virtues form the common themes that create a fascinating arc: What constitutes a holy life? It is about adventures, faith strength, and courage in the face of death.
