I found the following article by T.  David Gordon, “The Decline of Christianity in the West: A Contrarian View” while looking for something else. I think this is an important and relevent essay regarding the relation between the Christian Church and the State, and the dangers of the Church being to cozy with the State, or “using” the State to advance its cause. This is a controversial subject. T. David Gordon is former professor of New Testament at Gordon Conwell Seminary, and currently is on the faculty of Grove City College. I would be interested in your response to his position.
