Well in my experience we get church and Christianity confused to a large degree. Church as in congregational organizations of various denominations that we generally know is largely a human organization and is fraught with human failings, i.e. big business, petty jealousy etc. Christianity on the other hand is a completely different thing which is a belief that Jesus was the true son of God , that he gave his life on Calvary for the remission of our sins and that he arose on the 3rd day in victory over death. He provided us with tenants of how we should strive to live our lives but in the end given our human frailty to measure up to these tenants it is through his sacrifice and resurrection that ultimately reconciles us with God.
