There are differences over fundamental truths of the gospel, where the whole question of what defines a Christian is at issue. There also may be failings in the lives and Christian profession of believers. But there also may be differences over matters of personal judgement or behaviour in relations between those who are faithful believers. What may we learn about this kind of problem?
There are two New Testament examples that are of help, one involving two men and another involving two women.
Paul and Barnabas
This was a difference between two leaders of the church, about another believer, John Mark (Acts 15v36-41). He had assisted Paul and Barnabas during the Cyprus part of their first missionary journey (Acts 13v5), but then had left and returned to Jerusalem. Paul later suggests that they revisit the churches, but thought best not to take Mark. Barnabas disagrees, and “there arose a sharp disagreement, so that they separated from each other”. They both agreed that Paul’s proposal to revisit the churches was a good idea. But on the matter of Mark, Paul is adamant. Barnabas is equally convinced, and their emotions became heated. Age, family loyalties, upbringing – all were different.
