Unity is of surpassing importance to God, and is essential for a church to stand firm. And it is always your responsibility to reconcile, regardless of who is at fault or who is upset. The command is to have the same attitude (the attitude of Christ described in ch.2). We must accept and welcome those with differing opinions on disputable matters, without condemning, judging, or looking down on the person. When there is a conflict, those involved must try to resolve it privately first, but if that is unsuccessful, they should seek outside help. Paul shows by example that the way to have this attitude is by loving one another.
