What does the Bible say about Christ's position in the church?

The Bible explicitly shows that Christ holds a preeminent position in the church. As described in Revelation 2, He is seen not only as the glorified Christ but also as being in the midst of His churches. This illustrates that without Christ, there is no true church because He is the foundation, head, and purpose of the body of believers. Paul emphasizes this in Colossians 1:18, stating that He is the head of the body, the church, ensuring that all actions and functions of the church either glorify Him or are rendered futile without His guidance and authority.
