1. The Cornerstone Defined: A Foundation of Strength

A cornerstone, in its most basic sense, is the first stone laid in the construction of a masonry foundation. But its significance goes far beyond just being the first stone. It is the reference point for the entire structure, determining the alignment and stability of everything built upon it. Therefore, “What is a cornerstone?” is a fundamental question for understanding construction and symbolic principles.

1.1. Historical Significance of Cornerstones

Throughout history, the cornerstone has held a place of honor and importance. The laying of a cornerstone was often a ceremonial event, marking the official beginning of a building project. This ceremony often included blessings, prayers, and the placement of items of significance within the stone itself, such as coins, newspapers, and historical documents.

Ancient Civilizations: The Egyptians and Babylonians used cornerstones in their temples and monumental structures, believing they provided spiritual and structural stability.
Roman Empire: Roman engineers meticulously placed cornerstones to ensure the longevity and durability of their roads, aqueducts, and buildings.
Medieval Europe: The laying of a cornerstone for a cathedral or castle was a major event, often presided over by royalty or religious leaders.

1.2. The Cornerstone in Modern Construction

In modern construction, while the ceremony may be less elaborate, the principle remains the same. The cornerstone is still a critical element, ensuring the accuracy and stability of the entire building. Modern cornerstones may be made of concrete, stone, or other durable materials, and their placement is carefully calculated using advanced surveying techniques.

1.3. Figurative Use of the Cornerstone Concept

Beyond its literal meaning in construction, the term “cornerstone” is also used figuratively to represent something essential, fundamental, or indispensable. It can refer to a key principle, a core value, or a critical component of a system, organization, or belief. Understanding the figurative meaning of “What is a cornerstone?” can provide insight into its wider relevance.

3. Biblical Significance: Jesus Christ as the Cornerstone

In Christian theology, Jesus Christ is often referred to as the cornerstone. This metaphor highlights his central and foundational role in the Christian faith. It’s vital to understand what it means that Jesus Christ is the cornerstone.

3.1. Old Testament Prophecies

The concept of the cornerstone is found in several Old Testament prophecies, particularly in the book of Isaiah. These prophecies foretell the coming of a Messiah who would serve as the foundation for God’s people.

Isaiah 28:16: “Therefore thus says the Lord God, ‘Behold, I am laying in Zion a stone, a tested stone, a costly cornerstone for the foundation, firmly placed; he who believes in it will not be disturbed.'”
- This verse speaks of a “tested stone” and a “costly cornerstone” that will provide a firm foundation for those who believe. Christians interpret this as a prophecy of Jesus Christ.

3.2. New Testament References

The New Testament authors frequently use the cornerstone metaphor to describe Jesus Christ and his role in the church.

Ephesians 2:19-22: “So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God, built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone, in whom the whole structure, being joined together, grows into a holy temple in the Lord. In him you also are being built together into a dwelling place for God in the Spirit.”
- This passage emphasizes that the church is built on the foundation of the apostles and prophets, with Jesus Christ as the chief cornerstone.
1 Peter 2:4-8: “As you come to him, a living stone rejected by men but in the sight of God chosen and precious, you yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ. For it stands in Scripture: ‘Behold, I am laying in Zion a stone, a cornerstone chosen and precious, and whoever believes in him will not be put to shame.’ So the honor is for you who believe, but for those who do not believe, ‘The stone that the builders rejected has become the cornerstone,’ and ‘A stone of stumbling, and a rock of offense.’ They stumble because they disobey the word, as they were destined to do.”
- Peter highlights that Jesus is the “living stone” rejected by men but chosen by God, and that believers are also “living stones” being built into a spiritual house.

3.3. The Significance of Jesus as the Cornerstone

The metaphor of Jesus as the cornerstone has several important implications for Christian belief and practice.

Foundation of Faith: Jesus is the foundation upon which the Christian faith is built. All Christian doctrines and practices are rooted in his life, teachings, death, and resurrection.
Unity and Stability: Just as a cornerstone provides unity and stability to a building, Jesus Christ unites believers and provides stability to their lives.
Rejection and Acceptance: The scripture also speaks of the “stone the builders rejected,” which has become the cornerstone. This refers to the rejection of Jesus by some, and his ultimate triumph as the foundation of God’s plan.
