How do you treat people who disagree with you theologically?
There has been a lot of dissension in the church over this question. My computer’s dictionary describes “dissension” as a “disagreement that leads to discord,” and this may be part of the key. There is a type of disagreement that does not produce discord, disagreement over which friends can agree to disagree. That’s just healthy discussion.
Then of course there are those who think that any minor disagreement is worthy of a church battle, church discipline, and a church split. The words of Paul to Titus apply to them. “Warn a divisive person once, and then warn them a second time. After that, have nothing to do with them” (3:10).
