How do we know Christ is the cornerstone of the church?

The importance of Christ as the cornerstone is underscored in 1 Peter 2:6-7, where it is stated that Jesus is 'a chief cornerstone, elect, precious.' This passage confirms that Christ's identity as the cornerstone is divinely ordained, establishing the church's foundation on His sacrificial work and sovereign grace. Unlike Peter, who played a significant role in early church history, it is Christ's finished work and His authority that anchor the faith of believers and the structure of the church. The church stands firm in its teachings as long as it aligns itself with the gospel of Christ.
