A hallmark of the body of Christ is being one as the people of God. This oneness permeates all that we believe and all that we are in identity.

The church is our family, we are related through the blood of Jesus and remember that we are on equal footing when it comes to our salvation in Him (Galatians 3:27-28).
The church is precious to Jesus because He shed His blood for it (Acts 20:28). We must careful not to disrupt the unity that exists in this blood-purchased body among brothers and sisters in Christ. To be guilty of causing division is a most serious charge (Proverbs 6:19; 1 Corinthians 1:10-13).
"Division is clearly branded a sin in Galatians 5:19-21. Of the fifteen items listed "works of the flesh," eight have to do with those things that create disharmony or describe division among people: enmities, strife, jealousy, anger, quarrels, dissensions, factions, envy. People are following the flesh and not the Spirit if they allow nationality, color, social status, cultural mores, economic and political doctrines; educational attainments, or personality differences to keep them apart. Brotherhood is based on having the same divine Spirit" (1 Cor. 12:13) (Everett Ferguson, The Church of Christ (400-401).
