What does the Bible say about religious divisions?

In Luke 11:14-20, Jesus addresses the absurdity of division by illustrating that a kingdom divided cannot stand. This principle applies to the body of Christ; unnecessary divisions among believers over non-essential matters not only weaken the church but also bring scandal upon the faith. While separating from those who teach false doctrines is necessary, divisions over secondary issues should be avoided. Christians are encouraged to pursue a humble spirit, seeking unity through an enlightened understanding of Scripture, and distinguishing essentials from non-essentials. This pursuit reflects the desire for a united body working towards common goals in Christ.
