If Your Brother Sins Against You
15 “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. 16 But if he does not listen, take one or two others along with you, that every charge may be established by the evidence of two or three witnesses. 17 If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector. 18 Truly, I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed] in heaven. 19 Again I say to you, if two of you agree on earth about anything they ask, it will be done for them by my Father in heaven. 20 For where two or three are gathered in my name, there am I among them.” Matthew 18:15-20.
One point of contention is the responsibility to go to your brother, to tell the person of their fault in private, not to injure the person, but rather to win back your brother. Far too often, we fail to keep that command and harbor feelings that allow the root of bitterness to spring up in us (see Heb 12:15), whereby we no longer desire the unity of the spirit, and we walk away from congregations, brethren, and sadly, some even endeavor to leave the Lord! Paul however said,
22 You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires; 23 to be made new in the attitude of your minds; 24 and to put on the new self, created to be like God in true righteousness and holiness.
25 Therefore each of you must put off falsehood and speak truthfully to your neighbor, for we are all members of one body. 26 “In your anger do not sin”: Do not let the sun go down while you are still angry, 27 and do not give the devil a foothold. Ephesian 4:22-27
Further we are admonished in the Lord:
Let brotherly love continue – Hebrews 13:1
Love one another with brotherly affection. Outdo one another in showing honor.- Romans 12:10
Finally, all of you, have unity of mind, sympathy, brotherly love, a tender heart, and a humble mind. 9 Do not repay evil for evil or reviling for reviling, but on the contrary, bless, for to this you were called, that you may obtain a blessing. 1 Peter 3:8-9
Even Cain dared to ask, was he responsible for his brother Abel. But how is that different from our responsibility to go to our brother, so that no contention exists in the Body?
21 The eye cannot say to the hand, “I don’t need you!” And the head cannot say to the feet, “I don’t need you!” 22 On the contrary, those parts of the body that seem to be weaker are indispensable, 23 and the parts that we think are less honorable we treat with special honor. And the parts that are unpresentable are treated with special modesty, 24 while our presentable parts need no special treatment. But God has put the body together, giving greater honor to the parts that lacked it, 25 so that there should be no division in the body, but that its parts should have equal concern for each other.26 If one part suffers, every part suffers with it; if one part is honored, every part rejoices with it. 27 Now you are the body of Christ, and each one of you is a part of it. 1 Corinthians 12:21-27.
19 My brothers and sisters, if one of you should wander from the truth and someone should bring that person back, 20 remember this: Whoever turns a sinner from the error of their way will save them from death and cover over a multitude of sins. James 5:19-20.
