5 Bible Verses about Accusations, In Church Affairs

Do not take as true any statement made against one in authority, but only if two or three give witness to it.

And if your brother does wrong to you, go, make clear to him his error between you and him in private: if he gives ear to you, you have got your brother back again. But if he will not give ear to you, take with you one or two more, that by the lips of two or three witnesses every word may be made certain. And if he will not give ear to them, let it come to the hearing of the church: and if he will not give ear to the church, let him be to you as a Gentile and a tax-farmer.read more.
Truly I say to you, Whatever things are fixed by you on earth will be fixed in heaven: and whatever you make free on earth will be made free in heaven. Again, I say to you, that if two of you are in agreement on earth about anything for which they will make a request, it will be done for them by my Father in heaven. For where two or three are come together in my name, there am I among them.

Come to an agreement quickly with him who has a cause against you at law, while you are with him on the way, for fear that he may give you up to the judge and the judge may give you to the police and you may be put into prison. Truly I say to you, You will not come out from there till you have made payment of the very last farthing.

For if anyone has a cause at law against you, and you are going with him before the ruler, make an attempt, on the way, to come to an agreement with him, for if you do not, he may take you before the judge and the judge will give you up to the police, and they will put you in prison. I say to you, You will not come out of it till you have made payment to the very last farthing.

How is it, that if any one of you has a cause at law against another, he takes it before a Gentile judge and not before the saints? Is it not certain that the saints will be the judges of the world? if then the world will be judged by you, are you unable to give a decision about the smallest things? Is it not certain that we are to be the judges of angels? how much more then of the things of this life?read more.
If then there are questions to be judged in connection with the things of this life, why do you put them in the hands of those who have no position in the church? I say this to put you to shame. Is there not among you one wise man who may be able to give a decision between his brothers? But a brother who has a cause at law against another takes it before Gentile judges. More than this, it is not to your credit to have causes at law with one another at all. Why not put up with wrong? why not undergo loss? So far from doing this, you yourselves do wrong and take your brothers' property.
