On his journey to the Franciscan General Council in 1259, Bonaventure, having recently been elected minister general of the Order, stopped off to make a spiritual retreat on Mt. Alverna, the place where St. Francis had seen a vision of a six-winged Seraph with an image of the crucified Christ at its center from which he received the stigmata. It was here that Bonaventure was inspired to write a six-stage ascent of the mind into God, associating each stage of the ascent with one of the six wings of the Searph. By creatively adapting contemporary preaching techniques of the so-called “modern sermon” or sermo modernus style, Bonaventure was able to craft a work of which Bernard McGinn would say: “Perhaps no other treatise of comparable size in the history of Western mysticism packs so much into one seamless whole.” I also broach an issue that has divided commentators on Bonaventure’s leadership of the Franciscan Order since the moment he took office as minister general. In helping to foster the Franciscans presence at the University of Paris and other leading universities, did Bonaventure lead the Order in a direction contrary to the spirit of St. Francis?
