The term "Chief Cornerstone" in the Bible signifies Jesus Christ as the foundational stone of faith and the Church. The imagery of the cornerstone, which is the principal stone in a building that determines its structure and integrity, implies that Christ is the essential element for spiritual stability and unity. This concept is notably articulated in Ephesians 2:19-22, where Paul describes believers as being built upon the foundation of the apostles and prophets, with Christ Himself as the chief cornerstone. Additionally, this imagery is echoed in 1 Peter 2:6-7, which quotes Isaiah 28:16, stating, "Behold, I lay in Zion a chief cornerstone, elect, precious: and he that believeth on him shall not be confounded." The cornerstone metaphor emphasizes not only the foundational role of Christ in establishing the Church but also His unique authority and preciousness to believers. Thus, the Chief Cornerstone represents both the stability that faith in Christ provides and the unifying element of the Christian community, affirming that all spiritual life is built upon Him.
