Jesus has given the Church primary responsibility and authority for resolving conflict among Christians, and says we each should initiate the process of reconciliation. It is for us individually to take the first step, and Jesus describes a process involving private discussions, forgiveness, mediation, and the use of authority to make a binding decision to settle disputes.

“If your brother sins against you, go and show him his fault,
just between the two of you. If he listens to you, you have won your brother over.   But if he will not listen, take one or two others along so that every matter
may be established by the testimony of two/three witnesses.
If he refuses to listen to them, tell it to the church.
I tell you that if two of you on earth agree about anything you ask for,
it will be done for you by my Father in heaven.
For where two or three come together
in my name, there am I with them.”
(Matthew 18:15-20).

Jesus commands us to seek reconciliation with someone we have wronged or offended, even ahead of public worship:
“Therefore, if you are offering your gift at the altar and there remember
that your brother has something against you, leave your gift there
in front of the altar. 
First go and be reconciled to your brother; then come and offer your gift.   
Settle matters quickly with your adversary who is taking you to court. 
Do it while you are still with him on the way.”
 (Matthew 5:23-25).

This command is not conditional on how serious the other person’s complaint might be, or whether it is even justified. Even in difficult circumstances the Bible instructs us to make every effort to resolve personal differences outside the courtroom.

It is important for a Christian to resolve disputes privately
or by mediation or arbitration to prevent the dispute becoming public and thereby giving others opportunity to criticise
and mock Christianity.
