Have the right proportion. Keep disputable matters in their place as third-level issues. Don’t treat them like first- or second-level issues. And don’t become preoccupied with them or divisive about them. They shouldn’t be so important to you that it’s all you want to talk about. They shouldn’t be the main reason that you choose what church to join. They shouldn’t be issues that you are the most passionate about such that you are constantly trying to win people over to your position and then looking down on them if they decide not to join your side.
