“and on this rock”

And I tell you, you are Peter, and on this rock I will build my church

Matthew 16:18

On this rock I will build my church

The term “church” means “assembly” a term often used of Israel in the Old Testament. There is no controversy that Jesus is talking about the raising up and the building of a people of God, a holy nation. And this is what the Gospel has done as it has spread across the world. But what is the foundation for the church, this assembly, this people or as Peter will later call it a “spiritual house”? Who or what is Jesus referring to when he says, “this rock”? And how does this all relate to the “gates of hell” and the “keys of the kingdom of heaven”? And how does this all center around “You are the Christ, the son of the living God”?

Is the rock Peter?

The Catholics believe that “this rock” refers to Peter and in turn the succession of popes. If the term “rock” is referring to Peter as the leader or “pope” of the church, we don’t see this elsewhere. And this understanding does not appear to be clear either to Peter or the other disciples because they argued multiple times about who would be the greatest after this event. Also, immediately after this Jesus rebukes Peter and says, “Get behind me, Satan”. And the reason Jesus rebukes Peter is because he has strayed from the foundation of the faith. There being no other passage associating Peter with being the foundation or rock of the church, this verse is not the most solid grounds for claiming scriptural support for the pope. There is no scriptural or historical reason to assume that Peter is the “rock” Jesus is referring to, without bringing something outside of the scripture into the text.

How is the symbology of the rock used elsewhere?

However, we do get a consistent theme that is carried throughout scripture of the “rock”, “stone”, or “foundation” upon which the church is built all referring to this central phrase, “You are the Christ, the son of the living God”. When these illustrations are used, they are referring to Jesus, Jesus’ words, or the teaching of the Gospel.

Jesus quotes the Old Testament

Jesus earlier in a sermon talked about a house built on a rock, “Everyone then who hears these words of mine and does them will be like a wise man who built his house on the rock” (Matthew 7:24, ESV). Jesus also talks about the cornerstone, the stone the builders rejected, referring to himself and the message of the Gospel (Mt 21:42, Mk 12:10, Lk 20:17). Jesus takes this from Psalm 118:22 and Isaiah 28:16 both of these verses talk about putting ones trust in this cornerstone for salvation.

     Open to me the gates of 
     righteousness, 
          that I may enter through 
            them 
          and give thanks to the 
            LORD. 
     This is the gate of the LORD; 
          the righteous shall 
          enter through it. 
     I thank you that you have 
     answered me 
         and have become my 
          salvation. 
     The stone that the builders 
     rejected 
         has become the 
          cornerstone. 
     This is the LORD’s doing; 
         it is marvelous in our 
          eyes. 
     This is the day that the LORD 
     has made; 
          let us rejoice and be 
          glad in it. 
       (Psalm 118:19–24, ESV) 

Therefore this is what the Lord GOD says: “Behold, I am laying a stone in Zion, a tested stone, A precious cornerstone for the foundation, firmly placed. The one who believes in it will not be disturbed. (Isaiah 28:16, NASB)

Paul’s use of these terms

Paul also uses these symbols in relationship to the Jesus and the foundational teaching of the Gospel. In his letter to the Ephesians he writes,

And he came and preached peace to you who were far off and peace to those who were near. For through him we both have access in one Spirit to the Father. So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God, built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone, in whom the whole structure, being joined together, grows into a holy temple in the Lord. In him you also are being built together into a dwelling place for God by the Spirit. (Ephesians 2:17–22, ESV)

Paul also writes to the Corinthians, making it clear that, “no one can lay a foundation other than that which is laid, which is Jesus Christ” (1 Corinthians 3:11). He later tells the Ephesians, “grow up in every way into him who is the head, into Christ, from whom the whole body, joined and held together by every joint with which it is equipped, when each part is working properly, makes the body grow so that it builds itself up in love” (4:15-16, ESV). Paul warns the Galatians, “I am astonished that you are so quickly deserting him who called you in the grace of Christ and are turning to a different gospel – not that there is another one, but there are some who trouble you and want to distort the gospel of Christ” (Galatians 1:6,7, ESV). Paul makes it clear that this distinction and honor does not fall on Peter, “So let no one boast in men. For all things are yours, whether Paul or Apollos or Cephas or the world or life or death or the present or the future – all are yours, and you are Christ’s and Christ is God’s” (1 Corinthians 3:21-23, ESV).

Paul also makes it clear that it is by our confession and belief in Jesus that the church is built. In Romans 9:32-33, he summarizes these two passages in Isaiah

And he will become a sanctuary and a stone of offense and a rock of stumbling to both houses of Israel, a trap and a snare to the inhabitants of Jerusalem. And many shall stumble on it. They shall fall and be broken; they shall be snared and taken.” (Isaiah 8:14-15, ESV)

therefore thus says the Lord GOD, “Behold, I am the one who has laid as a foundation in Zion, a stone, a tested stone, a precious cornerstone, of a sure foundation: ‘Whoever believes will not be in haste.’ (Isaiah 28:16, ESV)

This is how he understand the meaning of these passages,

Why? Because they did not pursue it by faith, but as if it were based on works. They have stumbled over the stumbling stone, as it is written, “Behold, I am laying in Zion a stone of stumbling, and a rock of offense; and whoever believes in him will not be put to shame.” (Romans 9:32-33 ESV)

Notice that the distinction for Paul is belief in who Christ is. And it is this belief that Peter is confessing in this passage. When Jesus says on this rock I will build my church, he is referring to Isaiah 28:16, and the true Zion, whose foundation is built on the confession of faith.

It is clear from these Paul’s writing that the rock, the stone, the foundation of the church is Jesus and the teaching of the Gospel, which was given by the apostles, but how did Peter to whom Jesus spoke the words “on this rock I will build my church” see this? As we will see Peter will confirm this understanding and say that we who believe and confess that Jesus is the Christ, the son of the living God are by this confession built together into the temple of God.

Revelation

 When John describes Jerusalem coming down out of heaven, he describes “the wall of the city had twelve foundations, and on them were the twelve names of the twelve apostles of the Lamb” (Revelation 21:14). This is similar to Paul’s description of “of the household of God, built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone”. Notice Peter is not singled out, but instead this refers to the teaching of the apostles as they spread the Gospel throughout the world. The apostles had the unique role of initiating teaching to others the words of Christ as a firsthand account. Both Catholic, Orthodox, and Protestant agree that the apostles’ teachings are foundational to the church.

Daniel

Daniel in his interpretation of Nebuchadnezzar dream describes a stone,

As you looked, a stone was cut out by no human hand, and it struck the image on its feet of iron and clay, and broke them in pieces. Then the iron, the clay, the bronze, the silver, and the gold, all together were broken in pieces, and became like the chaff of the summer threshing floors; and the wind carried them away, so that not a trace of them could be found. But the stone that struck the image became a great mountain and filled the whole earth. (Daniel 2:34–35, ESV)

It is clear that this stone that becomes a mountain is the Kingdom of God, or the church, as it spreads, and the message of the Gospel conquers the hearts of men throughout the whole world. This dream emphasizes the fact that this stone was cut out by no hand, or no human. Paul also describes, “For we know if the tent that is our earthly home is destroyed, we have a building from God, a house not made with hands, eternal in the heavens” (2 Corinthians 5:1, ESV).

The writer of Hebrews describes this mountain,

For you have not come to what may be touched, a blazing fire and darkness and gloom and a tempest and the sound of a trumpet and a voice whose words made the hearers beg that no further messages be spoken to them. For they could not endure the order that was given, “If even a beast touches the mountain, it shall be stoned.” Indeed, so terrifying was the sight that Moses said, “I tremble with fear.” But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect, and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.

See that you do not refuse him who is speaking. For if they did not escape when they refused him who warned them on earth, much less will we escape if we reject him who warns from heaven. At that time his voice shook the earth, but now he has promised, “Yet once more I will shake not only the earth but also the heavens.” This phrase, “Yet once more,” indicates the removal of things that are shaken—that is, things that have been made—in order that the things that cannot be shaken may remain. Therefore let us be grateful for receiving a kingdom that cannot be shaken, and thus let us offer to God acceptable worship, with reverence and awe, for our God is a consuming fire.

(Hebrews 12:18–29, ESV)

Peter’s understanding of the rock

So who or what did Peter believe “this rock” to be? Peter is the one to whom Jesus is talking to when he says, “this rock”, and therefore has some authority in interpreting Jesus’ words and defining what Jesus meant by this phrase. So how does he use this symbology. In Acts 4:11, Peter clarifies who the cornerstone is, “This Jesus is ‘the stone you builders rejected, which has become the cornerstone.’ Salvation exists in no one else, for there is no other name under heaven given to men by which we must be saved”. This statement is similar to when Peter says to Jesus, “You are the Christ, the son of the Living God.” When Peter made this declaration, he is declaring Jesus to be the foundation and the one by whom we are saved. Elsewhere when Jesus asks his disciples if they too will leave him as many others had, Peter responds, “Lord, to whom shall we go? You have the words of eternal life, and we have believed, and have come to know, that you are the Holy One of God” (John 6:68,69). Peter understood who the foundation of the church was.

In Peter’s first letter in the Bible, he writes,

As you come to him, a living stone rejected by men but in the sight of God chosen and precious, you yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ. For it stands in Scripture:

     “Behold, I am laying in 
     Zion a stone, 
          a cornerstone chosen 
          and precious, 
     and whoever believes in 
     him will not be put to 
       shame.” 
     So the honor is for you 
     who believe, but for those 
     who do not believe, 
     “The stone that the 
     builders rejected 
          has become the 
          cornerstone,” 
     and 
     “A stone of stumbling, 
         and a rock of 
          offense.” 

They stumble because they disobey the word, as they were destined to do.

But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light. Once you were not a people, but now you are God’s people; once you had not received mercy, but now you have received mercy.

(1 Peter 2:4–10, ESV)

It is clear that Peter understood that the church was built on and centered on Jesus and the teaching of the Gospel and it is on this foundation alone that we as living stones are being built into the temple of God.

               In coming posts, we will explore how the “keys of the kingdom of heaven” and Jesus’ comment about the “gates of hell” fit in with the theme of the Gospel being preached to the world, further confirming that this is what Jesus meant by the “rock” and that this passage centers around Peter’s confession.
