Several priests of various orders were celebrating a liturgy during a retreat. They were Franciscans, Benedictines, Dominicans, Carmelites, and Jesuits.
Suddenly the lights of the retreat house dimmed and went out. The Franciscans burst into a song praising God for the darkness. The Benedictines continued the prayers from memory, without missing a beat. The Dominicans began to discuss light as a signification of the transmission of divine knowledge. The Carmelites fell into silence and started to practice slow, steady breathing. The Jesuits sent one of their guys into the basement to replace the fuse.
