The Church a greek fraternity?

Discussion in class on Friday about a Greek association got my wheels to spinning. I have spent many years attempting to reconcile the church's practices with the practices of the early synagogue and was always coming up short. I often wondered where different forms of government and a constant need to eat that seems to crop up in Corinthians was all about. The light has been turned on. It was the Greek association that led to the modern church and a good deal of current societies. I think that the theological implications of this are numerous. It allows us to take a step back and realize that while our leadership in churches do need to be Godly people, we may not need to try to fit ourselves into mold of deacon/elder that we so tenaciously cling to. I think that much of the conflict that we face as a result of our strict adherence to this archaic system could be stemmed off if we would just look at more efficient and modern ways to run our church. Obviously Paul had no problems taking ideas from his culture in order to find molds for church. Why should we?
