I will never forget one particular testimony I heard on one particular occasion in the church I served in Atlanta. He was a seminary professor, and he and his family were joining the church. And when it came his turn, he said, "I'm joining this church because those cannons across the street on the grounds of the State Capitol Building are pointed directly at us."

I thought at the time, "That's a strange answer." I had never noticed the cannons across the street. And I would look for them the next day, and, sure enough, there they would be, sitting there as mute relics of some war and pointing straight at the stone gothic sanctuary of my church across the street. I would note that, were they loaded, they could blow away the whole narthex. But at that particular moment in that particular Session meeting, I thought to myself, "That's a strange answer." "I'm joining this church," he said, "because those cannons are pointed directly at us."

People join the church for many reasons, but have you ever heard a reason like that?

As I got to know this seminary professor, I began to understand why he would join a church because of cannons pointed at it. Holding a Ph.D. from Duke, he was a student of Stanley Hauerwas. If you've never read any Hauerwas, I hope you will before you leave this place. Hauerwas has written widely about the modern-day perils of attempting to follow Jesus Christ in this culture. He and others have described Christians in our time as being something like "resident aliens" — faithful colonists in an otherwise hostile, post-Christian, secular society. He has tracked the decline of what he calls "the Constantinian arrangement" between the church and the powers-that-be, and he has asserted — rightly, I think — that that arrangement between the church and the emperor, which got started with Constantine, is breaking down in our time. I know enough about Stanley Hauerwas to have a sense of why a student of his would be intrigued at the thought of joining a church because it sits across the street from a hall of power and has cannons pointed at it.
