1. Christ is not divided and Christians should not be divided (1 Cor. 1:10-13). We must be diligent to keep the unity of the Spirit (Eph. 4:3) being unified in the same mind (Phil. 2:1-4; Rom. 15:6; Eph. 5:21).
2. Jesus prayed for unity the evening before being crucified (Jn. 17:13-23). We are perfected in unity (Jn. 17:23) by being sanctified in truth (Jn. 17:17, 19). The only basis for unity is God’s word (2 Tim. 3:16-17; 2 Jn. 1:9; cf. Rom. 2:8; 1 Cor. 3:1-4;Gal. 5:19-20)
3. Unity cannot be compromised. Unity commanded (1 Cor. 1:10).
4. Faithful Christians cannot be unified with unfaithful Christians (1 Cor. 11:17-19).
5. There is one unified body. We must be members of the body to be saved (Eph. 4:1-6; 5:23-24).
6. A congregation’s conduct is worthy of the gospel of Christ as the group strives together for the faith of the gospel (Phil. 1:27).
7. To avoid divisions, we must obey God and only do the things authorized by Christ (Acts 6:7; Rom. 10:17; 2 Tim. 3:16-17; Col. 3:17; 2 Jn. 1:9).
8. We must exercise church discipline (1 Cor. 5:1-13; 2 Th. 3:6, 14; Tit. 3:10-11; 2 Jn. 1:9-11), teach and preach God’s word, and not preach human doctrines.
