Our conflicting brothers guide is found in Mat. 18:15-17 (ESV):
If your brother sins against you, go and tell him his fault, between you and him alone. If he listens to you, you have gained your brother. But if he does not listen, take one or two others along with you, that every charge may be established by the evidence of the two or three witnesses. If he refuses to listen to them, tell it to the church, let him be to you as a Gentile and a tax collector.These verses reflect the biblical process for resolving conflicts between brethren, but care must be taken to insure that following this process doesn't generate additional problems that end up worse than the original. If I honestly, though unjustly, perceive a sin has been committed against me, and I roundup some of my biased friends to confront the "sinner" as witnesses, and my biased friends deem the evidence to be weighted in my favor, this would be unfair. It would be unfair even if the brother was actually guilty as charged. Imagine the consequences if this Christian charged with sinning against his brother is innocent, yet because of tainted testimony he is suddenly treated by the church as a "tax collector."
We pride ourselves in conforming our thoughts to Gods' Word, but often the scriptures are twisted just enough to fit our way of thinking. If the brother in the previous paragraph was honest about solving the problem with his brother, he would seek unbiased brothers/sisters to establish evidence that would be fair to all concerned.
I wonder if Jesus forgave those who sinned against him?
