Do not see artistic expression as "secular." Don’t consider artistic expression as "worldly." As God created them they are reflections of His image in us; and in fact, it is our duty to dedicate them—all our imaginative expressions and efforts—to His glory and for His purposes . . . of reflecting His truth, and beauty, and reconciliation in Jesus!! (1 Cor. 10:31)
Francis of Assisi (1182-1226) was the founder of the Franciscan order.
