"As there is a harsh and evil zeal which separateth from God and leadeth to hell, so there is a virtuous zeal which separateth from vice and leadeth to God and life everlasting. Let the monks, therefore, practice this zeal with most ardent love; namely, that in honor they forerun one another (cf Rom 12:10). Let them bear their infirmities, whether of body or mind, with the utmost patience; let them vie with one another in obedience. Let no one follow what he thinketh useful to himself, but rather to another. Let them practice fraternal charity with a chaste love."

--Rule of Saint Benedict Chapter 73
