Why Faith Grows Small, Not Big
Written by Josh Chevalier
Why Start Small (and Stay That Way)
This past Christmas, I went to a Christmas Eve service in a formalized church with a thousand people. We sang some songs and listened to a pastor share stories about the birth of Jesus.
But what struck me most that night wasn’t the sermon or the music.
It was a phrase I saw and heard repeated everywhere: on the walls, on the screens, and from the Pastor on the stage.
“Welcome Home.”
On the surface, it sounded warm and inviting. But the more I sat there, the more it created a strange sense of cognitive dissonance. I don’t know many houses that come with a stage, and none that can hold a thousand people.
But sitting there, that phrase started to feel more like a question:
“Welcome, home?”
And I wasn’t really sure why.
Until I learned about Dunbar’s Number.
Dunbar’s Number
In the early 1990s, British anthropologist Robin Dunbar discovered that humans can maintain about 150 stable relationships on average. This became known as Dunbar’s number, representing the cognitive limit on the number of people we can maintain meaningful social ties with.
But Dunbar didn’t stop there.
Over the next decade, Dunbar discovered that inside those 150 connections are smaller circles of intimacy: made up of around 15 friends.
These are the people you interact with regularly.
People you talk about real life with. People who know what’s happening in your world and whose lives you follow closely as well. You support each other, laugh together, and show up for each other when life gets messy.
In other words: these are the kinds of friendships where you feel known.
And if we’re honest, that’s what most people are actually longing for: unconditional friendships where they are known and loved as they are.
Why Circles, Not Rows
But those kinds of friendships don’t happen in rows.
They happen in circles.
They happen around tables, not stages.
Think about the places where you’ve felt most known.
It probably wasn’t in a crowd of hundreds. It was likely in a living room, around a dinner table, or sitting around a fire with a small group of friends.
Those environments create something that large gatherings simply can’t replicate: relational awareness.
You notice when someone is quiet.
You notice when someone’s missing.
You notice when something in their life has changed.
Think about it this way.
A stage creates an audience.
A table creates participants.
A stage says: Listen to the expert.
A table says: Tell me your story.
And faith was never meant to be something we watch. It was always, by design, meant to be something we learn together.
Which is why the earliest Christians followed the same pattern.
Luke describes the rhythm of the first church like this: “They devoted themselves to the apostles’ teaching and to fellowship, to the breaking of bread and to prayer” (Acts 2:42).
Notice what sits right next to teaching.
Fellowship.
Meals.
Tables.
A few verses later, Luke says: “They broke bread in their homes and ate together with glad and sincere hearts” (Acts 2:46).
The early Church didn’t gather primarily in auditoriums. They gathered in homes. Around food. Around conversation. Around one another.
In large spaces, people can disappear. In small spaces, people are visible.
And visibility is the starting point of belonging.
But belonging doesn’t happen instantly. It grows slowly through something far more valuable than programming:
Trust.
The Linchpin of Intimacy
Trust is at the center of this whole thing. And trust is not something that grows through sitting in a row. It happens in a circle around a table.
Trust is the linchpin of intimate relationships. Because without it, vulnerability never happens. And without vulnerability, relationships stay stuck at the surface.
But trust isn’t built through good branding or clever messaging.
Trust is built through spending time together, the consistency of showing up, and the honesty of real conversation.
Time matters because trust grows through repeated shared experiences: ordinary meals, everyday conversations, and showing up during both good and hard moments.
Consistency turns those moments into reliability, creating a sense of safety where people know they can count on one another.
Honesty then opens the door to intimacy, as conversations move beyond the surface-level into what’s really happening in life.
People stop performing, and they start showing up as themselves. And when that happens, when people feel safe enough to be real, belonging begins to take root.
And over time, those simple rhythms create the kind of relationships many people long for: unconditional friendships where they are known and loved as they are.
These are things that naturally develop in groups of 15, but they are impossible to cultivate with 150 people, let alone a thousand.
The Need for More
Interestingly, groups that start small often feel pressure to grow bigger. That’s why the “small group” model in a larger, formalized church never leads to a free world.
Sure. Growth looks impressive. Bigger numbers feel like progress. But if the goal is cultivating intimacy, starting small and staying that way is the wiser move.
Because once a group grows past a certain size, the dynamics begin to change.
Side conversations form.
Quieter voices fade into the background.
A few people dominate the interaction.
And suddenly the room starts behaving less like a circle and more like an audience.
At that point, the healthiest thing a community can do isn’t manage the size more tightly.
It’s start another table.
Not because the group failed, but because the relationships matter too much to stretch them beyond what they can sustain.
In short: starting small isn’t a compromise. It’s a commitment.
A commitment to environments where people are more than faces in a crowd. Where stories are remembered. Where absence is noticed. Where friendships deepen over time.
If Dunbar’s research is right, and the human brain can only sustain around fifteen close friendships at once, then building communities around that scale isn’t limiting; it’s freeing.
It’s simply aligning with how people were made.
And when communities are designed around human capacity instead of fighting it, something remarkable can happen.
People begin to feel welcome.
People begin to feel known.
People begin to feel loved.
And eventually, they begin to feel something that marketing slogans alone can never manufacture.
They begin to feel at home.
Which is where this conversation comes to play:
