Today’s feast of the great Franciscan friar, theologian, bishop and Doctor of the Church, Bonaventure of Bagnoregio (1221-1274), ought to be key on anyone’s radar screen is styles him or herself as well-read in theology. Famously he was cured of illness through the intercession of Saint Francis of Assisi. He was well-educated at the University of Paris where he became a popular preacher and teacher of theology and Scripture. For 17 years he guided the Franciscan fraternity and is known as a “second founder” of the Franciscans.
The pope nominated Bonaventure a bishop which he declined only to accept the papal honor of cardinal-bishop of Albano.
Dale M. Coulter wrote a very good appreciative of essay on Bonaventure: “On the Feast Day of St Bonaventure” (First Things online, July 15, 2014). I recommend it if you are serious about the study of sacred theology.
