How do we know that church unity is important?

The importance of church unity is rooted in the biblical teaching that all believers are members of one body in Christ (Romans 12:4-5). Unity is not merely an ideal; it is essential for the spiritual health of the church. The Apostle Paul emphasizes that despite the diversity of gifts and functions within the body of Christ, all members work together for the edification of the church. This unity signifies a collective witness to the truth of the Gospel and glorifies God as the church represents His love and truth to the world.
