It too is very important. It is the matter of the great New Testament concept of 'koinonia,' fellowship, oneness in Christ, one of the greatest themes in the Bible. A oneness that transcends barriers is one of the greatest evidences of the presence of God, but in Antioch this was being set aside for the sake of convenience. Thus, Paul faced a difficult problem. He could see that Barnabas, the man who had loved him even when he was Saul of Tarsus, the man who had stood by him and supported him when he was the persecutor of the church, 'even Barnabas' was led astray and needed to be challenged.
Christian leadership is a serious and difficult calling.
The pressures are great, but the need for righteousness is even greater. As it is true that all of us fail at times, it is a good thing to have a faithful brother or sister come alongside and straighten us out when failure occurs. We see before us the example of Christian leaders failing but being restored by one another. What I want to leave us with as a congregation are two things. First, I urge you to pray for anyone you know who has the mantle of leadership in Christ.
