The concept of the "Cornerstone in Zion" is a significant theological and prophetic theme found throughout the Bible, symbolizing the foundation of God's redemptive work through Jesus Christ. This cornerstone is both a literal and metaphorical element, representing strength, stability, and the fulfillment of divine prophecy.

Old Testament Foundations

The cornerstone imagery is rooted in the Old Testament, where it is often associated with the establishment of God's covenant and His chosen people. In Isaiah 28:16, the prophet declares, "So this is what the Lord GOD says: 'See, I lay a stone in Zion, a tested stone, a precious cornerstone, a sure foundation; the one who believes will never be shaken.'" This passage highlights the cornerstone as a divine provision, a tested and precious stone laid by God Himself, ensuring stability and security for those who trust in Him.

The cornerstone is also mentioned in Psalm 118:22, "The stone the builders rejected has become the cornerstone." This verse, while initially reflecting Israel's experience, prophetically points to the coming Messiah, who would be rejected by the leaders of His time but ultimately exalted by God.

New Testament Fulfillment

In the New Testament, the cornerstone imagery is explicitly applied to Jesus Christ, affirming His role as the foundation of the Church and the fulfillment of Old Testament prophecy. In Matthew 21:42, Jesus refers to Himself using Psalm 118:22, saying, "Have you never read in the Scriptures: 'The stone the builders rejected has become the cornerstone. This is from the Lord, and it is marvelous in our eyes'?" Here, Jesus identifies Himself as the cornerstone, rejected by the religious leaders but chosen by God as the foundation of His redemptive plan.

The Apostle Peter further elaborates on this theme in 1 Peter 2:6-7, quoting Isaiah 28:16 and Psalm 118:22: "For it stands in Scripture: 'See, I lay in Zion a stone, a chosen and precious cornerstone; and the one who believes in Him will never be put to shame.' To you who believe, then, this stone is precious. But to those who do not believe, 'The stone the builders rejected has become the cornerstone.'" Peter emphasizes the dual response to the cornerstone: belief leading to honor and unbelief resulting in stumbling.

Theological Significance

The cornerstone in Zion represents the centrality of Christ in God's salvific work. As the cornerstone, Jesus is the essential foundation upon which the Church is built, as stated in Ephesians 2:20-21: "built on the foundation of the apostles and prophets, with Christ Jesus Himself as the cornerstone. In Him the whole building is fitted together and grows into a holy temple in the Lord."

This cornerstone is not only foundational but also a point of division, as seen in 1 Peter 2:8, where it is described as "a stone of stumbling and a rock of offense" to those who reject Him. The cornerstone thus serves as a test of faith, distinguishing between those who accept Christ and those who reject Him.

Conclusion

The cornerstone in Zion is a profound biblical symbol that encapsulates the fulfillment of God's promises through Jesus Christ. It underscores the necessity of faith in Christ as the foundation of spiritual life and the Church, while also highlighting the consequences of unbelief. Through the cornerstone, believers find security, identity, and purpose in the redemptive work of God.
