'Brother' in the Bible

But you, why do you judge your brother? Or you again, why do you despise your brother? For we will all stand before the judgment seat of Christ.

Yet if because of food your brother is grieved, you walk no longer in love. Don't destroy with your food him for whom Christ died.

It is good to not eat meat, drink wine, nor do anything by which your brother stumbles, is offended, or is made weak.

Gaius, my host and host of the whole assembly, greets you. Erastus, the treasurer of the city, greets you, as does Quartus, the brother.
