St. Francis had a horror of expensive clothes and used to be delighted with coarse garments, adding that John the Baptist was praised by our Lord for being roughly clad. If the habit he was given felt too soft, he used to sew pieces of cord on the inside because, as he used to say, it is in the palaces of the rich that we must look for men who go clad in soft garments, not in the hovels of the poor. He knew from experience that the devils were afraid when they saw a person wearing rough clothes, whereas soft or luxurious garments gave them courage to attack more fiercely.
