A very early Franciscan document, Sacrum Commercium, The Sacred Exchange, begins with words reminiscent of the Bible’s Song of Songs: “Francis began to go about in the streets and crossings of the city, relentlessly, like a persistent hunter, diligently seeking whom his heart loved. He inquired of those standing about, he questioned those who came near to him, saying, ‘Have you seen her whom my heart loves?’” This kind of language and imagery for Franciscan poverty makes of poverty and penance a joyful enterprise, the joyful knight, Francis, going about the countryside as the embodiment of the good knight whose virtues are those of a knight of the new Round Table of the Lord. Poverty and penance, then, are not a grim affair, but the kind of derring-do a knight would perform to impress the Lady of the Castle, even rolling in briar bushes in the dead of winter to show his fidelity to her. This charges the tone of the early Franciscan Order with the chivalry and adventure of the Quest, a Spiritual Battle, fired by a deep and abiding love for Christ the Lord whose self-emptying is symbolized in Lady Poverty who was Christ’s vesture.
