'Sister' in the Bible

But you who eat vegetables only -- why do you judge your brother or sister? And you who eat everything -- why do you despise your brother or sister? For we will all stand before the judgment seat of God.

Therefore we must not pass judgment on one another, but rather determine never to place an obstacle or a trap before a brother or sister.

For if your brother or sister is distressed because of what you eat, you are no longer walking in love. Do not destroy by your food someone for whom Christ died.

Now I commend to you our sister Phoebe, who is a servant of the church in Cenchrea,

Greet Philologus and Julia, Nereus and his sister, and Olympas, and all the believers who are with them.
