What is the Purpose of the Church?

I can't help but think that we are in the middle of new era of theological thinking in the Church. As I studied theology in graduate school, a blaring omission presented itself. We have a solid case for the authority and reliability of the Bible. We have beautifully elegant Christology and painstakingly detailed formulas concerning salvation. We even think we know a thing or two about angelic beings and the last days. But what is sorely inadequate is a theology of the purpose and practice of the Church in community and society.
