From the field of Christian Bible Study...does anyone know where the Apostle Paul writes about when to or not to sue a brother?

Christians are recommended to go to a Christian non-involved 3rd party for arbitration. In Matthew 18, Jesus Christ recommended that a problem between 2 Christians be taken to the person directly first, then if no progress, another 2 or 3 witnesses go with while the original 2 parties try again to work out the issue. If the problem is unresolved and one party refuses God's instructions, then the matter goes before the entire church. And finally if one person still refuses God's instructions, then the church considers them a heathen and the matter can go public at that point.

I also want to point out that this is for when both parties consider themselves to be Christians. However, someone who refuses God's instructions is not Christian as Jesus Christ points out in Luke 8:21 KJV and Luke 6:46-49 KJV. If one of the people involved does not consider themselves Christian and has no interest in following God's instructions, then they go by civil law and it is lawful for a Christian to sue or press charges in order to expect justice and/or reparation of any financial damages or injuries caused by unlawful actions. It is loving to help someone realize the consequences of having to repair damages or restore people that their criminal actions have caused. It may help them consider ever committing that crime again if they are convicted and ultimately that helps them and any potential future victims of criminal actions they might commit if not being held accountable for crimes already committed.

1 Corinthians 6:1 KJV Dare any of you, having a matter against another, go to law before the unjust, and not before the saints? 2 Do ye not know that the saints shall judge the world? and if the world shall be judged by you, are ye unworthy to judge the smallest matters? 3 Know ye not that we shall judge angels? how much more things that pertain to this life? 4 If then ye have judgments of things pertaining to this life, set them to judge who are least esteemed in the church. 5 I speak to your shame. Is it so, that there is not a wise man among you? no, not one that shall be able to judge between his brethren? 6 But brother goeth to law with brother, and that before the unbelievers. 7 Now therefore there is utterly a fault among you, because ye go to law one with another. Why do ye not rather take wrong? why do ye not rather [suffer yourselves to] be defrauded? 8 Nay, ye do wrong, and defraud, and that [your] brethren.

Matthew 18:15 KJV Moreover if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother. 16 But if he will not hear [thee, then] take with thee one or two more, that in the mouth of two or three witnesses every word may be established. 17 And if he shall neglect to hear them, tell [it] unto the church: but if he neglect to hear the church, let him be unto thee as an heathen man and a publican.

Luke 8:21 KJV And he answered and said unto them, My mother and my brethren are these which hear the word of God, and do it.

Luke 6:46 KJV And why call ye me, Lord, Lord, and do not the things which I say? 47 Whosoever cometh to me, and heareth my sayings, and doeth them, I will shew you to whom he is like: 48 He is like a man which built an house, and digged deep, and laid the foundation on a rock: and when the flood arose, the stream beat vehemently upon that house, and could not shake it: for it was founded upon a rock. 49 But he that heareth, and doeth not, is like a man that without a foundation built an house upon the earth; against which the stream did beat vehemently, and immediately it fell; and the ruin of that house was great.

A person can know many truths by reciting daily and with care the angelic psalter of the Virgin Mary.

Of course it's best not to sue. But sometimes it is more loving to sue a brother than to allow another to suffer as a result. Ex: You have a child from an ex-husband who owes your child support. it'd be great if he's able and willing to bring his past due payments to date. But if not, it's better to take him to court that your son/daughter not suffer.

1 Corinthians 6:1-8

6 Does any one of you who has a dispute with another+ dare to go to court before unrighteous men, and not before the holy ones? 2 Or do you not know that the holy ones will judge the world?+ And if the world is to be judged by you, are you not competent to try very trivial matters? 3 Do you not know that we will judge angels?+ Then why not matters of this life? 4 If, then, you do have matters of this life to be tried,+ is it the men looked down on in the congregation whom you assign as judges? 5 I am speaking to move you to shame. Is there not one wise man among you who is able to judge between his brothers? 6 Instead, brother goes to court against brother, and before unbelievers at that!

7 Really, it is already a defeat for you when you have lawsuits with one another. Why not rather let yourselves be wronged?+ Why do you not rather let yourselves be defrauded? 8 Instead, you wrong and defraud, and your brothers at that!

1Co 6:3 Know ye not that we shall judge angels? how much more things that pertain to this life?

1Co 6:4 If then ye have judgments of things pertaining to this life, set them to judge who are least esteemed in the church.

1Co 6:5 I speak to your shame. Is it so, that there is not a wise man among you? no, not one that shall be able to judge between his brethren?

1Co 6:6 But brother goeth to law with brother, and that before the unbelievers.

1Co 6:7 ¶ Now therefore there is utterly a fault among you, because ye go to law one with another. Why do ye not rather take wrong? why do ye not rather suffer yourselves to be defrauded?

1Co 6:8 Nay, ye do wrong, and defraud, and that your brethren.

1Co 6:9 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,

1Co 6:10 Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.

Christians should always figure out how to get along.

if need be use a Christian arbiter when needed (someone without bias).

using the court systems may cause more problems and also far more money.

Christians should not sue Christians (unless they don't act like a Christian).

GOD will always help the Christian in such matters.

1 Corinthians 6:1-11.

I'm not sure where or even if Paul speaks about this but Jesus did. (oops... looks like Paul did in the answer below) At Matthew 5:25 Jesus states: "Be quick to settle matters with your legal opponent, while you are with him on the way there, so that somehow the opponent may not turn you over to the judge, and the judge to the court attendant, and you get thrown into prison.

In essence Jesus is telling us to seek peace even if it is not in our own best interests. He urged his disciples to be mild tempered and peacemakers and to eliminate causes for anger. Even to love our enemies as his heavenly Father Jehovah did.

Thanking all for their serious and exacting answers!! <><

1 Corinthians 6:1-8

Dare any of you, having a matter against another, go to law before the unrighteous, and not before the saints? 2 Do you not know that the saints will judge the world? And if the world will be judged by you, are you unworthy to judge the smallest matters? 3 Do you not know that we shall judge angels? How much more, things that pertain to this life? 4 If then you have judgments concerning things pertaining to this life, do you appoint those who are least esteemed by the church to judge? 5 I say this to your shame. Is it so, that there is not a wise man among you, not even one, who will be able to judge between his brethren? 6 But brother goes to law against brother, and that before unbelievers!

7 Now therefore, it is already an utter failure for you that you go to law against one another. Why do you not rather accept wrong? Why do you not rather let yourselves be cheated? 8 No, you yourselves do wrong and cheat, and you do these things to your brethren!

the lord your god....
