3 The Foundation of the Church
Christ is the foundation and cornerstone of the church.
He declares Himself as the Rock on which the church is founded. “And I say also unto thee, That thou art Peter, and upon this rock I will build my church” (Matt. 16:18). The church was not founded on Peter, nor Peter’s confession, nor upon truth as such, but upon the immovable Rock of Ages. “Thou art Peter,” from the Greek petros, meaning a stone that can be moved, used in a metaphorical sense of Peter whom Satan threw around yet was he never crushed. The Greek word for rock on which the church was founded is petra, meaning a large and immovable rock.
The apostle Paul declares that Christ is the foundation, I Cor. 3:11 – “For other foundation can no man lay than that is laid, which is Christ Jesus.” This should settle all cavil forever.
Prophecy designates Christ as the foundation of the church, Isaiah 28:16: “Therefore thus saith the Lord God, Behold, I lay in Zion for a foundation a stone, a tried stone, a precious cornerstone, a sure foundation: he that believeth shall not make haste.” The apostle Peter alludes to this prophecy in his message to the Jewish Christians scattered abroad, and also applies it to Christ (I Peter 2:6). Furthermore, Christ is not only the foundation of the church; He is also its cornerstone, thus tying all the building and its foundation together.
The apostle Paul testifies that Christ is the foundation, Eph. 2:20: “And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief cornerstone.” Christ was the foundation of the apostles and prophets, on which foundation the church was founded. He was their foundation, and He is the church’s foundation.
