1 Corinthians 6:6

but when a contest arises, you must refer the decision to infidels?

the next day seeing some that were fighting, he would have persuaded them to agree, saying, sirs, ye are brethren; why do ye injure one another?

When any controversy arises among you, will any one presume to appeal to the Gentiles, and not to Christians?

beside, you are absolutely in the wrong in going to law with one another at all: why don't you rather take wrong? why do ye not rather suffer loss?

Are you not become associates with infidels? but what affinity is there between virtue and vice? and what communication has light with darkness?

do every thing without murmuring and disputes:

he that says, he is in the light, and yet hates his brother, is still in darkness.

for this is the doctrine that you have heard from the beginning, that we should love one another.

But brother goeth to law with brother, and that before the unbelievers.

When any controversy arises among you, will any one presume to appeal to the Gentiles, and not to Christians?

the next day seeing some that were fighting, he would have persuaded them to agree, saying, sirs, ye are brethren; why do ye injure one another?

do every thing without murmuring and disputes:

he that says, he is in the light, and yet hates his brother, is still in darkness.

for this is the doctrine that you have heard from the beginning, that we should love one another.

but if you bite and tear one another, take heed that you be not consumed by one another.
