One of the Main Functions of the Church
Jesus asked the disciples in Matthew 16:13, “Who do people say that the Son of Man is?” They said in the next verse, “Some say John the Baptist; and others, Elijah; but still others, Jeremiah, or one of the prophets.” Jesus then asked them in verse fifteen, “But who do you say that I am?” At this time Simon boldly answered in verse sixteen, “You are the Christ, the Son of the living God.” In the next verse we see that Jesus was greatly pleased with Simon’s answer and said, “Blessed are you, Simon Barjona, because flesh and blood did not reveal this to you, but My Father who is in heaven.” Jesus then renamed Simon Peter saying, “I also say to you that you are Peter, and upon this rock I will build My church.”
When Jesus renamed Simon He called him Peter which is Petros in Greek. Petros is a small stone or a rock. A brick can fall under the category of a petros. It is certainly not a foundational stone that someone would build a house on. Rather it would be the small stones, like bricks, that would rest upon the foundational stone.
After Jesus named Simon Petros, He said “upon this rock I will build my church.” The word that Jesus used for rock was a different word than the one He used for Simon Peter. Jesus used the Greek word petra as the rock that the church would be built upon. Petra is a large rock, a foundational stone that is much different than the small stone, petros, Simon was called. Clearly Peter is not the foundational stone that the church is built upon; Jesus is. Jesus is the one who gave His life so He could redeem the church. To say any other is the foundation of the church is not only biblically inaccurate, it is outright blasphemous.
Peter clearly understood what Jesus was talking about. Peter wrote in I Peter 2:4-5, “And coming to Him as to a living stone which has been rejected by men, but is choice and precious in the sight of God, you also, as living stones, are being built up as a spiritual house.” Who is the living stone? Jesus is. He is the one that was rejected by men, but choice and precious in the sight of God. We are the ones who come to Him also as living stones that are being built up as a spiritual house. This is the perfect portrait of the church.
The church is not a physical building, an address, or location. The church is a spiritual house. Jesus is the living stone that is the foundation. We are living stones being built up on that foundation. Just as bricks are laid atop of the foundation of the building we are laid atop of Jesus who is the foundation of the church. We are also laid atop of all of the other believers who came before us such as Peter. Peter was named Petros because he was the first to confess Jesus as the Christ. Upon our confession of Christ we are saved and therefore laid atop of the foundation of Christ as the church.
After Peter gave us this wonderful picture of the structure of God’s spiritual house he then gave us an understanding of its function. He said in I Peter 2:9, “you are a chosen race, a royal priesthood, a holy nation, a people for God’s own possession, so that you may proclaim the excellencies of Him who has called you out of darkness into His marvelous light.” Jesus didn’t save us to give us a get out of hell free card. He saved us out of darkness and into light so we would have a relationship with Him and so we would proclaim to the rest of the world, which remains in darkness, of His excellencies and His marvelous light so they too would be drawn to the light and have a relationship with Him and not stand in darkness separated from God doomed to eternal condemnation. Clearly, this is one of the main functions of the church; the whole church.
