What does the Bible say about the union between Christ and the church?

Scripture elaborates on this union in Ephesians 5:30-32, highlighting that we are united with Christ both legally and spiritually. This intimate relationship mirrors the marriage bond, illustrating the depth of love and commitment between Christ and His people. Paul states, 'For we are members of his body, of his flesh, and of his bones,' signifying that this relationship is not merely metaphorical but rooted in a profound spiritual reality, as believers are represented as the body of Christ, collectively dwelling in Him and deriving their identity and purpose from Him.
