The following is from the editorial of issue 45/46 of The Briefing.
In Mark chapter 9, the apostles encounter an alarming scene—they find someone casting out demons in the name of Jesus without official authorization. After a stop-work meeting, they decide that the scab exorcist is acting outside the provisions of the award and should desist immediately or face a campaign of rolling stoppages.
Jesus, of course, rebukes them for their narrow, sectarian attitude. Jesus is not really talking about false teaching, but about whether it is necessary to wear the right badge and belong to the right club in order to be on the right side. The answer is clearly ‘No’.
In the New Testament, there is a spectrum of teaching on how we should relate to people with whom we disagree. At one end of the spectrum, there are passages like Mark 9, which warn us not to be too exclusive. We should warmly accept people who labour for the Lord Jesus in different ways or in different places or under different brand names. We should not censure them just because they aren’t ‘one of us’.
At the other end of the spectrum is Galatians 1:6-9—
I am astonished that you are so quickly deserting the one who called you by the grace of Christ and are turning to a different gospel—which is really no gospel at all. Evidently some people are throwing you into confusion and are trying to pervert the gospel of Christ. But even if we or an angel from heaven should preach a gospel other than the one we preached to you let him be eternally condemned!
There are a number of other passages that we could place at different points along the spectrum between these two, such as the following:
- Philippians 1:15-18: Even though the gospel is being preached from poor motives by Paul’s opponents, Paul rejoices that at least Christ is being preached!
- Romans 14: Paul exhorts the Roman Christians not to be picky with each other. They should accept each other generously, without passing judgement over disputable matters.
- 1 Timothy 1:3-4: Part of the elder’s responsibility is to silence those who promote false doctrines and idle speculation (also see Titus 1:9-11).
- 2 Timothy 2:24-26: In dealing with opponents, the Lord’s servant must resist the temptation to be resentful and unkind. Instead, he must gently correct and instruct in the hope that God will grant his opponents repentance.
- 2 Corinthians 11:1f: Paul is jealous for the Corinthians because he is worried that they are beginning to accept a different gospel.
With Mark 9 at one end of the spectrum and Galatians 1 at the other, it is not always easy, in the heat of the situation, to work out the right response. It is easy to say in hindsight that Paul was right to oppose Peter and Barnabas over the circumcision issue in Galatians 2. But how would it have been for Paul, eyeball-to-eyeball with Peter, that apostolic heavy weight, and Barnabas, Paul’s trusted colleague? In the situation, it is often hard to formulate the right response, especially given our sin and wiles of Satan.
