This weekend I watched a very unique documentary called Into Great Silence, about the daily lives of the monks at the Grande Chartreuse, which is the seat of the Carthusian order of monks in the Catholic church. At one point the monks are eating together while one brother reads a book of monsatic rules which I couldn't identify, but it was a text something like the rule of St. Benedict, and at one point it began talking about proper behavior if one must pass through a town. I cannot find the text (likely because the subtitles where a freelance translation) but it it specifically prohibited 'entering the house of seculars' or eating or drinking anything while in the area.
This naturally stuck out like a sore thumb to me after reading the Cross an text. I'm honestly not sure why this change took place in Christianity. What was it in Christianity that changed? Was it the simple fact that it went from being a peasent's movement to something institutionalised and thus became antipopulist in exactly the way it was populist in the beginning?
