Hello, John!
St. Bonaventure is not among the best-known Franciscan saints, but he was essential in solidifying the structure of the early Franciscan brotherhood. He helped shepherd the friars through a period of uncertainty and fragmentation after Francis's death.
Scholar Sister Ilia Delio, OSF, explores Bonaventure's inspiring theology in her book Crucified Love: Bonaventure's Mysticism of the Crucified Christ. In this comprehensive study, she explores the breadth and depth of medieval philosophy and theology in a way that makes it relevant to the 21st century.
