"Those who cause division"

Kevin DeYoung on the "Distinguishing Marks of a Quarrelsome Person":

You don’t have to be a card-carrying member of the nice Nazis to believe that quarreling is wrong. You only have to believe the Bible (James 4:1). Hot-headed, divisive Christians are not pleasing to God (Proverbs 6:19). We are told to drive them out (Proverbs 22:10) and avoid such people (Romans 16:17). This doesn’t mean we only huddle with the people we like. We are not talking about awkward folks or those who disagree with us.
