Scripture commands unity among believers while insisting on doctrinal fidelity. Paul rebuked the Corinthians for saying "I follow Paul" or "I follow Apollos" — such factionalism is carnal (1 Corinthians 3:3-4). Yet Paul also commanded separation from false teachers (Romans 16:17) and warned that divisions would come to reveal who is genuine (1 Corinthians 11:19). The tension is real: Christians must contend for truth, which sometimes requires organizational distinction, while guarding against the sinful tribalism that elevates a label above the Lord.
Denomination: a class or collection of individuals called by the same name.
DENOMINATION, n. 1. The act of naming. 2. A name or appellation; a class or collection of individuals called by the same name. Webster applied the term broadly, not specifically to church divisions. The system of denominationalism as an organized feature of American Christianity was already emerging in Webster's era.
• 1 Corinthians 1:10-13 — "Is Christ divided? Was Paul crucified for you?"
• 1 Corinthians 3:3-4 — "When one says, 'I follow Paul,' and another, 'I follow Apollos,' are you not being merely human?"
• Ephesians 4:3-6 — "Eager to maintain the unity of the Spirit in the bond of peace."
• Romans 16:17 — "Watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught."
Denominationalism has produced both carnal tribalism and shallow non-denominationalism that avoids accountability.
Denominationalism corrupts in two directions. Some treat their denomination as an identity marker stronger than their identity in Christ — Baptist first, Christian second. Others react by becoming "non-denominational," which often means no theological accountability, no confessional standard, and a pastor answerable to no one. The irony is that many "non-denominational" churches are simply independent denominations of one — all the isolation, none of the accountability. The biblical model is local churches in fellowship with one another, united by common confession, with elders who are accountable to sound doctrine and to each other.
• "Paul did not ask 'Are you Baptist or Presbyterian?' — he asked 'Is Christ divided?'"
• "'Non-denominational' often means no confession, no accountability, and a pastor who answers to no one."
• "Denominational identity is useful for theological clarity but sinful when it replaces identity in Christ."
