'Brother' in the Bible

But you, why do you criticize your brother? Or you again, why do you look down on your [believing] brother or regard him with contempt? For we will all stand before the judgment seat of God [who alone is judge].

Then let us not criticize one another anymore, but rather determine this—not to put an obstacle or a stumbling block or a source of temptation in another believer’s way.

If your brother is being hurt or offended because of food [that you insist on eating], you are no longer walking in love [toward him]. Do not let what you eat destroy and spiritually harm one for whom Christ died.

It is good [to do the right thing and] not eat meat or drink wine, or do anything that offends your brother and weakens him spiritually.

Gaius, who is host to me and to the whole church here, greets you. Erastus, the city treasurer, and our brother Quartus, greet you.
