If a pastor wants to start a row, he needn’t preach heresy. All he needs to do is change the color of the carpet in the church nursery or bring a drum set onto the platform. People might not notice the heresy, but everyone will notice the carpet and the drum set.Churches are famous for their “we-never-did-it-that-way-before” mindset, though, in fact, churches are no more prone to such thinking than the Kiwanis, the Chamber of Commerce or the United States Senate.
