One of the difficult skills a leader needs to learn is dealing with people who are damaging your organisation. A church environment is supposed to reflect Christian virtues such as love and joy and peace and harmony, so it is very difficult to confront someone who is dragging the team down, perhaps by malicious gossip or anger attacks or some other form of selfishness. But confrontation is necessary, as Paul indicated in the first chapter of his letter to Titus:
There are a lot of recalcitrant people, empty talkers and deceivers, especially those who claim that circumcision is necessary, and their mouths have to be shut. They are damaging whole families, teaching improper things as a disgraceful way of making a profit… Reprimand them sharply, so that they can come to a correct understanding of the faith, and stop listening to Jewish myths and the instructions of people who twist the truth.
If unhelpful conduct is allowed to continue unchecked, the problem festers. Other people’s attention is diverted to repairing the damage being caused by the offender, and the work of the church effectively grinds to a halt. So a leader has no choice: the offender has to be confronted and the problem has to be stopped. It can be very difficult to conduct a confrontation in a manner which reflects the love and self-control of Jesus, but a leader has to learn to do it.
