The Franciscan traditions provides Franciscan friars with a simple and robust theology of fundraising.
Thomas of Celano, the first biographer of St. Francis, records his words:
"There is a contract between the world and the brothers: the brothers must give the world a good example, the world must provide for their needs. When they break faith and withdraw good example, the world will withdraw its hand in just censure."
(Remembrance of the Desire of a Soul / 2nd Life of St. Francis, XL/86:4, trans. Placid Hermann, OFM)
