Over at First Things, Peter Leithart has written an article addressing the connection between social life and spiritual life. I commend this article for your reading.
This is dark, but the Christian assessment is darker still. According to the New Testament, social life is never merely social. It’s always also spiritual. According to St. Paul, supra-human “principalities and powers” infest and pervert political life. God is an active player in our politics, and no realistic appraisal of our situation can ignore the central role of the universal Judge.
