How do we know that Christ represents His Church?

The relationship between Christ and His Church is richly portrayed throughout the New Testament, emphasizing that Christ represents His Church in both a mystical and tangible manner. In 1 Corinthians 12:12, it is stated, 'For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ.' This illustrates the deep interconnection and representation of Christ within the collective of believers. Moreover, Ephesians 5:30 says, 'For we are members of his body, of his flesh and of his bones,' signifying that the identity of Christ encompasses His people. This theological understanding emphasizes that the life of believers reflects Christ's own life, establishing His intimate and enduring presence with them.
