Benedict
In the 500's AD, Benedict was the founder of a new Christian movement toward monasticism. Already in the 300's, especially in Egypt, men and women had been going off by themselves into the desert, away from people, to live a life of prayer, devoted entirely to God. These men and women were called monks (and the women gradually came to be called nuns). But as there got to be more and more of these monks, and not just in Egypt but all over the Christian world, and not just in the desert but even in towns and cities, it got harder and harder to figure out whether somebody was really devoting herself to God, or if she was really some kind of scam artist. Benedict organized a community of monks in Italy, and wrote up a set of rules for them to live by. Gradually people agreed, all over the Christian world, that you should only trust monks who lived by the rules of these communities, with somebody who was in charge of them and could vouch for their character.
