Many people misunderstand Jesus’ words in Matthew 16:18—“on this rock I will build my church”—and use them to justify claims of exclusive authority or elevate one church tradition above others. But when you look at the context and original language, it’s clear Jesus wasn’t declaring Peter the supreme leader of all Christians. Instead, He was pointing to something bigger: the unshakable truth of who He is—“the Christ, the Son of the living God.” That truth is the real foundation of the Church.
Understanding what “this rock” actually means helps you defend your faith, avoid false teachings, and keep your focus on Jesus as the true cornerstone. It clears up confusion about church authority and gives you solid ground to stand on in conversations about doctrine and leadership. Keep reading to dive deeper into this important verse and learn how to explain it clearly and biblically.
If you’ve ever had a conversation about church leadership or doctrine, there’s a good chance someone brought up Matthew 16:18:
“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 one verse has sparked debates for centuries. The phrase “on this rock” is often misunderstood or misused, especially when people try to use it to claim absolute authority for one church tradition or leader. If you’re trying to understand what Jesus actually meant—and how to explain it clearly to others—you’re in the right place.
Let’s walk through the most common misinterpretations, what the Bible really says, and how you can confidently explain it.
1. The Context: What’s Actually Happening in Matthew 16?
Before we look at the phrase itself, let’s understand what’s going on in the passage.
In Matthew 16:13–20, Jesus asks His disciples who people say He is. Then He asks them directly:
“Who do you say I am?”
Peter answers boldly in verse 16:
“You are the Messiah, the Son of the living God.”
Jesus responds by affirming Peter’s statement and says:
“Blessed are you, Simon son of Jonah… and I tell you that you are Peter, and on this rock I will build my church.”
So the big question is: What exactly is “this rock”?
2. Misinterpretation #1: Peter Is the Sole Rock and Supreme Authority
This is the most common misunderstanding—especially in Catholic tradition. The claim goes something like this:
Since “Peter” means “rock,” Jesus was declaring Peter the first pope, and all authority in the Church flows from him.
But let’s look closely at the Greek.
- “Peter” is Petros — a masculine noun meaning a small stone or rock.
- “Rock” is petra — a feminine noun referring to a large bedrock or foundation.
So while there’s a wordplay going on, Jesus is not saying Peter is the entire foundation. In fact, the language suggests a distinction between Peter (Petros) and the foundational rock (petra). That’s why many scholars, especially in Protestant circles, interpret “this rock” as:
- Peter’s confession that Jesus is the Christ.
- Jesus Himself as the ultimate foundation.
Supporting 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.”
Nowhere else in the New Testament is Peter singled out as the foundation of the universal Church. He’s a key figure, yes, but the Church is ultimately built on Christ and His truth, not one man.
3. Misinterpretation #2: The Verse Grants Unlimited Authority to Church Leaders
Some use Matthew 16:18–19 to claim that Jesus gave Peter—and by extension, church leaders—infallible authority to make decisions, declare doctrine, and even override Scripture.
Let’s clear this up:
“I will give you the keys of the kingdom of heaven…” — Matthew 16:19
The “keys” represent responsibility and stewardship, not supreme control. Peter and the other apostles were given authority to teach and lead, but not independent of Christ or His Word.
Compare Matthew 18:18
Just two chapters later, Jesus gives the same “binding and loosing” language to all the disciples—not just Peter.
Also, when Peter later made mistakes, like refusing to eat with Gentiles, Paul publicly corrected him (Galatians 2:11–14). If Peter had infallible authority, this wouldn’t have happened.
Bottom line:
The Church’s authority is real, but it’s always under the authority of Christ and Scripture—never above it.
4. Misinterpretation #3: Only One Denomination Is the True Church
Some groups take Matthew 16:18 to mean:
“Jesus said He’d build His church—so if you’re not in our denomination, you’re outside of it.”
This narrow interpretation misses the entire point of what Jesus was doing.
Jesus wasn’t founding a denominational system. He was:
- Confirming His identity as Messiah.
- Establishing His mission to build a unified, global Church.
- Declaring that truth, not tradition, would be the foundation.
The “Church” (Greek: ekklesia) means “the called-out ones”—all believers in Christ. That includes people across time, cultures, and traditions who hold to the truth of the gospel.
5. So What Is the Rock?
Here’s a clear explanation you can use:
- Jesus is using wordplay with Peter’s name, but He’s pointing to something bigger.
- The “rock” is either Peter’s confession that Jesus is the Messiah or Jesus Himself as the foundation.
- In either case, it’s truth, not personal status, that’s the foundation of the Church.
Remember:
“You are the Christ, the Son of the living God.” — That’s the rock-solid truth the Church is built on.
6. How to Respond When Someone Misuses This Verse
Here’s a simple way to handle it:
If someone says:
“This verse proves Peter was the first pope.”
You can say:
“Peter was a key leader, but Jesus didn’t make him the foundation of the Church. Scripture shows that Christ is the cornerstone, and Peter himself pointed to Jesus as the ‘living stone’ (1 Peter 2:4–6).”
If someone says:
“Only our church has the authority Jesus gave in this passage.”
You can say:
“Jesus gave authority to all His disciples to preach, teach, and make disciples—not just one group. The Church is built on truth, not exclusivity.”
7. Why This Matters Today
Understanding what “on this rock” really means helps you:
- Defend your faith with confidence.
- Avoid being misled by false claims of exclusive authority.
- Stay focused on Jesus as the true foundation of the Church.
It’s not about elevating one man or one institution. It’s about pointing to the truth of who Jesus is—and building your life on that solid ground.
🔑 Key Takeaways
- “On this rock” is often misinterpreted to promote exclusive or infallible church authority.
- The biblical context and original language point to Christ or His truth as the true foundation.
- The Church’s authority is real—but it’s always under Jesus and guided by Scripture.
- Jesus promised to build His Church, and He still is—on the solid foundation of gospel truth.
Conclusion
When Jesus said “on this rock,” He wasn’t handing over unchecked power to a single person or group. He was anchoring the Church in a truth that never changes: He is the Christ, the Son of the living God. That truth is the foundation we still stand on today—and it’s one you can defend with clarity and confidence.
10 FAQs for Debunking Misinterpretations of “On This Rock”.
1. What does Jesus mean by “on this rock” in Matthew 16:18?
Jesus is referring to the foundational truth that He is the Messiah, the Son of the living God—not just to Peter himself. This truth is what the Church is built on.
2. Is Peter the rock that Jesus was talking about?
Peter plays a role, but the language and context suggest the “rock” is more likely his confession of faith or Jesus Himself, not Peter as an individual with supreme authority.
3. Why does the Greek text matter in understanding this verse?
In Greek, “Peter” (Petros) means a small stone, while “rock” (petra) refers to a large foundation. This distinction supports the view that Jesus wasn’t declaring Peter as the sole foundation.
4. Did Jesus make Peter the first pope?
There’s no biblical evidence that Jesus established Peter as a pope. While Peter was a key leader, Scripture emphasizes Christ as the foundation of the Church (1 Corinthians 3:11).
5. What are the keys of the kingdom mentioned in verse 19?
The keys represent spiritual authority and responsibility to proclaim the gospel and lead the Church—but this authority is under Christ, not above Him.

Yes. Verses like Ephesians 2:20 and 1 Peter 2:6 clearly say Jesus is the cornerstone of the Church, not any one apostle.

No. In Matthew 18:18, Jesus gives similar authority (“binding and loosing”) to all the apostles, not just Peter.

10. What’s the big takeaway from Matthew 16:18?
The Church stands on the unshakable truth of who Jesus is. That truth—not a person or tradition—is the rock Christ builds His Church upon.
