In this article, we explore whether Matthew 16:18 truly proves the existence of one “true” Church. While many argue that the verse establishes a single institution with exclusive authority, we examine three common interpretations of the phrase “on this rock” and how they align with the broader teachings of Scripture. By diving into the original Greek and comparing the verse with other biblical passages, we see that the foundation of the Church is not a person or denomination, but the truth of who Jesus is as the Christ, the Son of the living God.
The article clears up common misconceptions about church authority and shows that the true Church is made up of all believers in Christ, united in faith. If you’ve been curious about the significance of this verse or want to better understand what it says about Church structure and unity, keep reading for a deeper dive into what Matthew 16:18 really teaches and how to use it in conversations about faith and doctrine.
One of the most quoted verses in church authority debates is Matthew 16:18. Jesus says to Peter:
“And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it.” — Matthew 16:18 (NIV)
This verse is often used to argue that Jesus established one visible, institutional church—and that any group outside of it is illegitimate. But is that really what Jesus meant? Does Matthew 16:18 prove there’s only one “true church,” and if so, which one is it?
If you’ve wrestled with these questions—or faced them in conversations—you’re not alone. Let’s take an honest, biblical look at this verse and explore what it really means.
1. The Claim: One Church, One Authority
Some Christian traditions, particularly the Roman Catholic Church, use Matthew 16:18 to support the idea that:
- Jesus founded a single, visible Church.
- Peter was the first pope.
- That authority continues through apostolic succession in one specific church.
From this view, Matthew 16:18 is seen as exclusive proof of one true institution, and all other Christian expressions are “less than” or even invalid.
But here’s the problem: this interpretation depends on assumptions not directly supported by the verse—or the rest of Scripture.
2. What the Verse Actually Says
Let’s read it again, slowly:
“You are Peter, and on this rock I will build my church.”
There’s a wordplay happening in the original Greek:
- “Peter” = Petros (a stone or small rock)
- “Rock” = Petra (a massive bedrock)
So what’s the “rock”?
There are three common interpretations:
- Peter himself is the rock (Roman Catholic view).
- Peter’s confession that Jesus is the Messiah (Protestant view).
- Jesus Himself as the rock (also supported by Scripture).
Let’s break each one down briefly.
3. View #1: Peter Is the Rock (Catholic View)
Yes, Peter was a leader. Yes, Jesus gave him a special role. But does that mean Peter was the supreme leader of a global institution?
Problems with this view:
- The rest of the New Testament never refers to Peter as the singular head of the Church.
- Peter is later corrected publicly by Paul (Galatians 2:11–14).
- The “keys of the kingdom” given in Matthew 16:19 are later given to all the apostles (see Matthew 18:18).
- No mention of succession from Peter to future “popes” appears in Scripture.
This interpretation reads more into the verse than Jesus actually says.
4. View #2: Peter’s Confession Is the Rock
Right before verse 18, Peter says:
“You are the Christ, the Son of the living God.” — Matthew 16:16
Jesus blesses Peter and responds to that confession. Many Bible scholars believe it’s this truth—that Jesus is the Messiah—that is the true rock.
This lines up with other Scripture:
- 1 Corinthians 3:11 — “For no one can lay any foundation other than the one already laid, which is Jesus Christ.”
- Ephesians 2:20 — The Church is built on the foundation of the apostles and prophets, with Christ Jesus Himself as the chief cornerstone.
This view makes better sense of the whole Bible and puts the focus where it belongs: on Christ, not a man.
5. View #3: Jesus Is the Rock
Throughout Scripture, God is called “the Rock”:
- Psalm 18:2 — “The Lord is my rock, my fortress and my deliverer.”
- 1 Corinthians 10:4 — “They drank from the spiritual rock… and that rock was Christ.”
It would be totally consistent for Jesus to be calling Himself the rock—the unshakable foundation of the Church. This is both theologically solid and biblically consistent.
6. What “My Church” Actually Means
Jesus says, “I will build my church.”
Let’s be clear—this is His Church, not Peter’s, not ours, not any one denomination’s.
The Greek word for “church” here is ekklesia, which means assembly or called-out ones. It refers to people, not buildings or institutions.
Nowhere in this verse does Jesus say:
- Which structure the church will take.
- What leadership hierarchy it must follow.
- That there will only be one visible, infallible organization.
Instead, He promises that His people, built on the truth of who He is, will prevail—even against the powers of death.
7. What About Unity?
Yes, the Bible calls for unity:
- John 17:21 — Jesus prays that His followers would be one.
- Ephesians 4:4–6 — One body, one Spirit, one Lord, one faith.
But biblical unity is rooted in truth, not just external alignment. The Church is united in Christ, not necessarily in a single organization.
The idea that only one institution can be “the true church” ignores the reality of:
- Millions of faithful believers across denominations.
- Shared core doctrines (like Christ’s divinity, resurrection, and salvation by grace).
- The universal Church (capital “C”) made up of all true believers worldwide.
8. What This Means for You
If someone claims Matthew 16:18 proves there’s only one true church—and it’s theirs—you need to ask:
- Is that what Jesus actually said?
- Does the rest of Scripture support their claim?
- Are they pointing to Christ, or to human authority?
Here’s what you can know for sure:
✅ Jesus builds His Church.
✅ That Church is founded on the truth of who He is.
✅ No power—hell, culture, sin, or death—can defeat it.
✅ You don’t need to belong to one specific denomination to be part of it.
9. A Clear, Biblical Apologetic Answer
If someone challenges you, here’s a simple response:
“Matthew 16:18 shows that Jesus is building His Church on the truth that He’s the Christ—not on one person or one group. The true Church is made up of all believers who hold to that truth. That’s what Scripture consistently teaches.”
🔑 Summary: What Matthew 16:18 Really Teaches
- The “rock” is best understood as either Jesus Himself or the truth Peter confessed.
- There’s no biblical support for one infallible, visible institution ruling over all Christians.
- Jesus’ Church is built on truth, not tradition.
- The real “one true Church” is made up of all who believe in and follow Jesus as Lord.

10 FAQs
1. What does Matthew 16:18 really mean?
Matthew 16:18 is often interpreted as Jesus declaring Peter the foundation of the Church, but a deeper look shows that the “rock” refers to the truth of Peter’s confession—that Jesus is the Christ, the Son of the living God—not to Peter himself.
2. Does Matthew 16:18 prove there’s only one true Church?
No, the verse doesn’t establish the idea of a single, infallible Church. The Church is built on the truth of who Jesus is, not on any specific human leader or denomination.
3. What does “on this rock” refer to in Matthew 16:18?
The “rock” is likely a reference to Peter’s confession of faith or, more likely, Jesus Himself as the Messiah. The verse emphasizes the foundational truth about Christ, not the person of Peter.
4. Is Peter the foundation of the Church according to the Bible?
Peter played a crucial role, but the Bible consistently teaches that Jesus is the ultimate foundation of the Church (1 Corinthians 3:11; Ephesians 2:20).
5. Why do some believe Matthew 16:18 refers to Peter’s authority?
Some interpret this verse to support the idea that Jesus gave Peter, as the first pope, ultimate authority over the Church. However, this view isn’t supported by the broader context of Scripture.
6. Does the Catholic Church have a valid claim to be the one true Church based on this verse?
While the Catholic Church interprets Matthew 16:18 as evidence of papal authority, the verse doesn’t support the idea of one institution holding exclusive authority. The Church is made up of all believers who confess Jesus as the Christ.
7. How does the Greek language influence the interpretation of this verse?
In Greek, “Peter” (Petros) means a small stone, and “rock” (petra) refers to a large foundation. This distinction suggests the “rock” is more than just Peter—it’s the truth of who Jesus is.
8. What does “the gates of Hades will not overcome it” mean?
This phrase means that the Church, built on the truth of Jesus, will be indestructible, even in the face of death and evil. Nothing will defeat it, as Christ’s power is the ultimate foundation.
9. Can this verse be used to argue for unity in the Church?
Yes, it can. Matthew 16:18 emphasizes that the Church is unified in the truth of who Jesus is. True unity comes from faith in Christ, not alignment with a specific institution.
10. What is the main takeaway from Matthew 16:18?
The main takeaway is that the Church is built on the unshakable truth of Jesus Christ. This truth, not a human leader or institution, is the foundation that guarantees the Church’s enduring strength.
