Someone has a nice exegesis of the 4 Gospels in which he says that each one addresses a particular social order--tribe, empire, Israel, Greece. In addition, they make a circle, in that the end of Matthew leads into the beginning of Mark, and so on, such that the end of John leads back to Matthew. And these social orders remain in layers of calendars. Community, tribal; empires, business/work; Israel, church; Greece, education. This is very wise. And this one says that we now enter a neo-tribal era, where ridding ourselves of the perpetual warfare of the tribe is the key, while keeping the small, enthusiastic groups. We rid ourselves of the worst of the other two already, and Greece should never be an imperative, only a companion.
