There are many one another passages in the New Testament which show the need Christians have for each other. The church consists of “one body in Christ with many members, like the many parts of a human body function in harmony (Romans 12:5). Christians are connected to one another.
Before his death, Jesus gave this commandment to his disciples: “A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another. By this all people will know that you are my disciples” (Jn 13:34-35). Most of the “one another” passages are found in Paul’s letters, too many to list here. A few are: Rom 12:10; 12:16;15:7,14; Gal 5:13; 6:1-2; Eph 4:3-4, 25, 32; 5:21; Col 3:12-14). Perhaps a hundred more could be given if space allowed. Several other passages teach what we must NOT do in our relations with each other (Rom 14:13; Gal 5:15, 26; Col 3:9; Jam 4:11-12).
Good shepherds (elders) oversee members in the local church body, assuring harmony among the various members. Acts 20:28-30 predicts some elders would later distort the truth, which would cause division in the church body. In such cases, Christians must “obey God rather than man” (Acts 5:29) when elders are not faithful to the Word.
