Where is Christ described as the 'chief cornerstone'?

• A. In Ephesians 3:6.
• B. In Ephesians 2:20.
• C. In Colossians 1:18.
• D. In 1 Peter 2:6.

Answer: (B)

The main idea here is how Christ anchors and unites the church. In Ephesians 2:20, Paul explicitly states that believers are “built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief cornerstone.” This image shows Jesus as the central, alignment-keeping piece of the entire structure—the church—so that all parts fit together in unity under his teaching and role. The surrounding context in Ephesians 2 reinforces that Jews and Gentiles are reconciled and brought into one dwelling for God, with the church described as a holy temple in the Lord, precisely held together by Christ as the chief cornerstone. While other verses speak of Christ’s leadership or use similar imagery, this verse directly names him as the chief cornerstone of the church’s foundation.
