When Fellowship Goes Deeper Than What You Have in Common
What keeps people together? Ask anyone who has walked away from a marriage, a friendship, or a church, and you'll often hear the same reason: we just didn't have anything in common. It's one of the most natural explanations in the world — and according to Pastor Benjamin Robinson of Lineage Church, it might also be one of the most spiritually dangerous assumptions we bring into the body of Christ.
In part two of the Koinonia series, Pastor Robinson unpacks what true Christian fellowship really means — and why it runs far deeper than shared ethnicity, life stage, socioeconomic status, or even personality.
What Does Koinonia Actually Mean?
The Greek word koinonia appears throughout the New Testament and is most often translated as "fellowship." But the word carries a richer meaning than a potluck dinner or a Sunday handshake. Koinonia means common, shared, participation together in something. It describes the very substance of what binds people to one another.
Pastor Robinson frames it this way: just as the church doesn't simply have an assembly — the church is an assembly — the church doesn't simply have fellowship. The church is a fellowship. You cannot opt out of genuine koinonia and still claim to be fully participating in the life of the church.
The key passage anchoring this message is Acts 2:42–47:
"And they continued steadfastly in the apostles' doctrine and fellowship, in the breaking of bread, and in prayers… Now all who believed were together and had all things in common."
All things in common. That phrase is the heartbeat of koinonia.
The Problem With Natural Fellowship
Human beings are wired to bond over shared experiences and identities. Pastor Robinson illustrates this with a disarmingly relatable story about golf. As a 26-year player who freely admits he still doesn't play well, he describes how walking into an airport and spotting a stranger wearing a Titleist hat is enough to ignite instant brotherhood. No introduction needed. No shared history required. One common passion creates immediate connection.
That kind of affinity-based fellowship isn't wrong in ordinary life. But when it becomes the primary filter for how we build community in the church, something breaks down. We start sorting ourselves by:
- Ethnicity and cultural background
- Age and life stage
- Socioeconomic status
- Shared language or accent
- Whether our kids are the same age
These are all natural, understandable categories. But Paul, writing in Ephesians 4:1–6, calls the church to something categorically different:
"There is one body and one Spirit, just as you were called in one hope of your calling; one Lord, one faith, one baptism; one God and Father of all, who is above all and through all and in you all."
The foundation of Christian fellowship isn't what we share naturally — it's what we share supernaturally.
Pentecost and the Reversal of Babel
To understand why Acts 2 is so radical, you have to understand the crowd. The Day of Pentecost was one of three major Jewish feasts that drew Jewish people from across the known world back to Jerusalem. Parthians, Medes, Elamites, residents of Mesopotamia — people who shared an ancestral faith but had lived for generations in different nations, speaking different languages, absorbing different cultures. In the most practical sense, they had very little in common.
And then the Holy Spirit fell.
The disciples began speaking in tongues, and the miracle wasn't just one of speaking — it was one of hearing. Every person in that crowd heard the message in their own native language. Someone heard Persian. Someone else heard Parthian. Another, Mede. They were talking to each other in Greek, the common language of the diaspora, and yet each one was hearing something deeply personal and native to them.
Pastor Robinson draws a powerful contrast here: at the Tower of Babel, God used language to divide humanity. At Pentecost, God used language to unite what had been scattered. The miracle of tongues wasn't chaos — it was the beginning of a new kind of community that transcends every human boundary.
Peter stood up, interpreted the moment through the prophecy of Joel, and preached Jesus — his death, his resurrection, his lordship. Three thousand people repented, were baptized, and were added to the church in a single day. And what happened next? All who believed were together and had all things in common.
Before Christ, they had nothing in common. After Christ, they had everything in common.
One Lord, One Faith, One Baptism
This is the theological core of Ephesians 4. Paul doesn't build unity on cultural affinity. He builds it on a sevenfold foundation:
- One body — we belong to the same church
- One Spirit — we are all indwelled by the same Holy Spirit
- One hope — we share the same eternal destination
- One Lord — Jesus Christ is Lord over all of us equally
- One faith — we hold the same apostolic gospel
- One baptism — we have each made the same public declaration
- One God and Father — we are all children of the same Father
This isn't a list of preferences or personality traits. These are the deepest realities of who we are as believers. And if these are truly what we hold in common, then every other difference — age, background, skin color, income, language — becomes secondary.
What This Means for the Local Church
For anyone who has ever walked away from a church because they "didn't have anything in common" with the people there, this message is both a challenge and an invitation. The question isn't whether you share hobbies, life stages, or cultural backgrounds with the people sitting near you. The question is whether you share the same Lord, the same Spirit, the same hope.
If the answer is yes, you have everything in common that actually matters.
True koinonia asks us to walk worthy of our calling — with lowliness, gentleness, long-suffering, and bearing with one another in love (Ephesians 4:1–2). That's not passive tolerance. It's active, Spirit-empowered commitment to a unity that the world didn't create and cannot manufacture.
The early church in Acts 2 didn't bond over demographics. They bonded over a resurrection. They shared possessions, broke bread together daily, and praised God with gladness and simplicity of heart — and the Lord added to their number every single day.
That's what koinonia looks like when it's rooted in the right foundation. Not in what we naturally share, but in what we have been given in Christ.
