How do we know that Jesus is the cornerstone of the Church?

The belief that Jesus is the cornerstone of the Church is firmly rooted in Scripture, specifically in Ephesians 2:20 and Psalm 118:22. In these passages, Jesus is depicted as not just a supporter but the essential foundation upon which the Church is built. He claimed this role in the Gospels (Mark 12:10, Luke 20:17), affirming that He fulfills the prophetic declaration about the rejected stone becoming the cornerstone.

Moreover, the theological implications of Jesus as the cornerstone extend to His unique position in the economy of salvation. He is not only foundational in terms of construction but also significant for believers’ salvation and community. His work on the cross forms the basis of our righteousness, enabling Jews and Gentiles alike to be united in faith. This foundational aspect underscores that without Him, the Church cannot stand firm. Thus, the doctrinal truths embedded in these scriptures provide a solid assurance of His identity as the cornerstone.
