What does the Bible say about the role of Christ in the Church?

The Apostle Paul emphasizes in Colossians 2:19 that Christ is the head of the Church, and it is from Him that the body of believers, each a member, derives its nourishment and spiritual growth. He encourages the Colossians to recognize that all the ceremonial laws and practices have been fulfilled in Christ. They are no longer bound by these old ways, and instead, they should hold fast to Christ, who is the source of life and unity in the Church. If the Church does not hold to Christ, it becomes disjointed and fails to thrive.
