A Tale of Three Members
Three Church Members You Will Become Like (3 John)
3 John is the shortest letter in the New Testament, but it gives us something incredibly practical: three portraits of church membership.
Not as gossip.
Not as drama.
But as a mirror.
When you read 3 John, you can’t avoid the question:
Who am I becoming in the church?
- Gaius — the faithful supporter
- Diotrephes — the proud gatekeeper
- Demetrius — the man of integrity
1) Gaius: Faithfulness That Funds the Mission (3 John 1–8)
John calls him “beloved” and says he loves him “in truth” (v. 1). In John’s world, “truth” is not just correct information. Truth is Jesus Christ. So John is saying: I love you in Christ. John prays for Gaius’ health and his soul (v. 2), and then he explains why:
Gaius is the kind of church member who strengthens the mission.
“I rejoiced greatly when the brothers came and testified to your truth… as indeed you are walking in the truth.” (v. 3)
Here’s what Gaius was doing:
- welcoming traveling gospel workers (even “strangers”)
- supporting them
- sending them on their way “in a manner worthy of God” (v. 6)
In the first century, churches didn’t have buildings. They met in homes. Missionaries didn’t have apps, donors, or newsletters. They depended on faithful Christians like Gaius, who opened their homes and used their resources for the kingdom.
And John makes a major point:
“Therefore we ought to support people like these, that we may be fellow workers for the truth.” (v. 8)
The lesson
You might not preach. You might not travel. You might not be “platformed.”
But you can still become a fellow worker for the truth through faithfulness, hospitality, generosity, and service.
Gaius shows us this:
Faithfulness is not about fame. It’s about love that opens the door.
2) Diotrephes: A Warning Against Pride in the Church (3 John 9–11)
Then the tone shifts.
John says:
“Diotrephes, who likes to put himself first, does not acknowledge our authority.” (v. 9)
That is a terrifying sentence.
This isn’t a random opinion. This is the apostle John—the last living apostle—writing with Christ-given authority. And Diotrephes responds with pride.
What does pride look like in the church?
- he rejects apostolic authority
- he spreads “wicked nonsense” (v. 10)
- he refuses to welcome brothers
- he blocks others from welcoming them
- he kicks faithful people out of the church (v. 10)
Diotrephes didn’t just want influence. He wanted preeminence. He wanted to be “first.” And that spirit always damages the church.
That’s why John gives this command:
“Beloved, do not imitate evil but imitate good.” (v. 11)
The lesson
The church doesn’t need people who love being seen.
The church needs people who love being faithful.
3) Demetrius: Integrity That Builds Trust (3 John 12–15)
Finally, John highlights Demetrius:
“Demetrius has received a good testimony from everyone, and from the truth itself.” (v. 12)
Demetrius is probably the one carrying this letter. John wants Gaius to know: you can trust him.
Why?
Because Demetrius isn’t one person at church and another person outside of church. His life matches his confession. The “truth itself” testifies about him.
A church moves forward when it has people whose lives are consistent—people with integrity, reliability, and quiet faithfulness.
Not everyone is Gaius with resources.
But everyone can be Demetrius with integrity.
3 John forces a personal question:
Which one am I most like right now?
- Gaius (open-handed faithfulness)
- Diotrephes (self-first pride)
- Demetrius (integrity and trustworthiness)
And if you don’t like what you see, the gospel gives you hope: you can change—because Christ changes people.
Conclusion: The Church Needs Faithfulness, Not Hot Takes
Our culture rewards loud voices. The New Testament honors faithful lives.
God is not asking you to be famous.
God is not asking you to be impressive.
God is asking you to be faithful.
Faithfulness looks like:
- opening your life
- serving the saints
- supporting the work
- walking in truth
- resisting pride
- living with integrity
And when a church becomes full of Gaiuses and Demetriuses, the gospel advances.
