The first mention of the “church” in the Bible appears in Matthew 16:18, where Jesus tells Peter, “I will build my church.” This moment is foundational because it reveals that the church isn’t a building or an institution, but a community of people called out to follow Jesus. The “rock” Jesus refers to is the truth Peter declared—that Jesus is the Messiah. Jesus promises that this church will stand strong against all opposition, assuring believers of its unstoppable nature.
Understanding this helps you see that being part of the church means being part of God’s family, united by faith in Jesus and called to live out His mission. The church is a living body of believers, not just a Sunday event. If you want to grasp more about what Jesus really meant and how this shapes your faith and community today, keep reading for a deeper dive into the first mention of the church in the Bible.
When most people think of “church,” they picture a building, a Sunday service, or maybe a group of believers singing worship songs. But what did Jesus really mean when He first used the word “church”? Was He talking about a religious institution or something much deeper?
Let’s go straight to the source: the Bible. The first time the word “church” appears is in Matthew 16:18, and understanding this moment is key to understanding what Jesus really intended.
1. Where Is “Church” First Mentioned in the Bible?
The very first time the word “church” is used in Scripture is in Matthew 16:18 (ESV), where Jesus says to Peter:
“And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it.”
That’s it. That’s the first mention. But there’s a lot packed into that one sentence. To fully understand it, we need to break it down.
2. What Did Jesus Mean by “Church”?
The word “church” in this passage is translated from the Greek word “ekklesia”, which literally means “called-out ones” or “assembly.” It wasn’t a religious word at the time. In ancient Greek society, an “ekklesia” was a political gathering of citizens called together to make decisions.
So, when Jesus said, “I will build my church,” He wasn’t talking about a building or a denomination. He was talking about a people—specifically, those called out of the world to follow Him.
Key Point:
- Church = a community of believers, not a physical place.
3. The Context: Why Did Jesus Say This?
To understand what Jesus meant, you’ve got to look at what happened right before this verse.
In Matthew 16:13–17, Jesus asks His disciples a crucial question:
“Who do you say that I am?”
Peter answers boldly in verse 16:
“You are the Christ, the Son of the living God.”
That’s when Jesus responds with the famous declaration:
“Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven. And I tell you, you are Peter, and on this rock I will build my church…”
Jesus ties the foundation of the church to Peter’s confession—not just Peter the man, but the truth he spoke: Jesus is the Christ.
4. What’s “the Rock” the Church Is Built On?
This part has caused debate for centuries. Let’s clear it up.
- The Greek word for Peter is Petros, meaning “small stone.”
- The word Jesus uses for “rock” is petra, meaning “massive rock.”
So Jesus says something like: “You are Petros, and on this petra I will build my church.”
Most Bible scholars agree: the church isn’t built on Peter himself, but on the truth of his confession—that Jesus is the Messiah.
That truth is the immovable foundation of the church.
5. “The Gates of Hell Will Not Prevail” — What Does That Mean?
Jesus makes a bold promise: the gates of hell (Greek: Hades) won’t overcome His church.
This doesn’t just mean the church will survive—it means it’s on the offensive. Gates don’t attack; they’re defensive. Jesus is saying His church will be so strong that even death and darkness can’t stop it.
It’s a promise of victory, not survival.
6. The Church Isn’t a Place, It’s a People
Jesus used the word “church” only twice in the Gospels:
- Matthew 16:18 – the verse we’ve been unpacking.
- Matthew 18:17 – where He talks about resolving conflict in the church community.
In both cases, He wasn’t talking about buildings or religious institutions. He was talking about a group of people living out God’s Kingdom on earth.
What the Church Is (Biblically):
- A community of believers (Acts 2:42–47)
- A body with many parts (1 Corinthians 12:12–27)
- The bride of Christ (Ephesians 5:25–27)
- God’s dwelling place (Ephesians 2:19–22)
The church is a living organism, not an organization. And it began with Jesus’ call to build it Himself.
7. What Does This Mean for You?
Let’s make this personal.
If you believe Jesus is the Christ, you’re part of that church He talked about. You don’t have to “join” the church like a club. You’re born into it spiritually through faith in Christ.
Being part of Jesus’ church means:
- You belong to God’s family.
- You have a purpose in His mission.
- You’re called to live differently.
- You don’t fight alone—you’re part of a spiritual army.
8. A Brief Timeline: How the Church Grew After Jesus
Understanding the first mention helps you appreciate how the church exploded in the early years. Here’s a quick timeline:
| Event | Reference | Significance |
| Jesus mentions the church | Matthew 16:18 | First time the word is used |
| Pentecost: church is empowered | Acts 2 | Holy Spirit comes, 3,000 saved |
| Early church life | Acts 2:42–47 | Believers gather, share, grow |
| Gentiles added to the church | Acts 10 | Gospel spreads beyond Jews |
| Church expands across the Roman world | Acts 13–28 | Paul and others plant churches |
It all started with a single sentence: “I will build my church.”
9. Final Thoughts: Why Jesus’ Words Still Matter Today
The church isn’t man’s idea—it’s Jesus’ idea. He said He would build it, and for over 2,000 years, He’s been doing just that.
When Jesus first used the word “church,” He made it clear:
- It’s His church.
- It’s built on the truth of who He is.
- It’s unstoppable.
You don’t need to wait for Sunday to be the church. If you follow Jesus, you are the church—wherever you are.
So the next time you hear the word “church,” don’t just think of pews and pulpits. Think of a global movement of believers who confess that Jesus is the Christ, the Son of the living God.

- The first time “church” is mentioned in the Bible is Matthew 16:18.
- Jesus used the Greek word ekklesia, meaning a called-out community—not a building.
- The church is built on the truth that Jesus is the Messiah.
