What Is the Underground Church? House Churches Under Pressure, Explained
From Beijing apartments to Algerian garages, millions of Christians worship where public church is restricted or dangerous. Here is what the underground church is, where it is, how it survives — and how to stand with it
The short answer
An underground church, or house church, is a Christian congregation that meets privately — in homes, apartments, garages or outdoors — because public worship is restricted, unregistered or dangerous. Underground churches exist in countries such as China, where unregistered congregations like Beijing's Zion Church and Chengdu's Early Rain Covenant Church have seen leaders imprisoned; Iran, where much of the church meets in secret; Algeria, where nearly all Protestant churches have been sealed; and North Korea, ranked first on Open Doors' 2026 World Watch List. The model echoes the earliest church, which met in homes (Acts 2:46; Romans 16:5).
When Christians in the West hear "church," they usually picture a building. For millions of believers around the world, church is a living room with the curtains drawn, a rented apartment that changes every few months, or a garage where the singing stays quiet. This is the underground church — and it's the setting for many of the stories we report.
What the Underground Church Is
An underground church (often called a house church) is a congregation that meets privately — in homes, apartments, garages, offices or outdoors — because public worship is restricted, requires registration believers won't accept, or is simply dangerous.
"The underground church is believers meeting in homes and hidden places where public worship is restricted or dangerous — in China, North Korea, Iran, Algeria, Malaysia and beyond. It's the church's original shape, it pays a real price, and it asks the rest of us not to forget it."
Click to copy and share"Underground" doesn't mean hidden in every case. Some house churches are well known to authorities and tolerated until they aren't. What they share is that they meet outside the official, approved structures — and pay a price for it.
It's How the Church Began
House churches aren't a modern workaround; they're the church's original shape. The first believers "broke bread in their homes and ate together with glad and sincere hearts" (Acts 2:46). The church prayed for Peter's release in Mary's house (Acts 12:12). Paul greeted "the church that meets at their house" (Romans 16:5). For its first three centuries, Christianity grew largely without church buildings.
Where Underground Churches Are Today
Our reporting has followed several:
- China. Unregistered congregations refuse state control of their teaching. Eight leaders of Beijing's Zion Church remain imprisoned, and advocates cite more than 200 church leaders behind bars (our report). Pastor Wang Yi of Chengdu's Early Rain Covenant Church is serving nine years, and elderly members were detained this autumn for a teahouse Bible reading group (our report).
- North Korea. First on Open Doors' 2026 World Watch List; Open Doors estimates around 400,000 Christians there, worshipping in the deepest secrecy.
- Iran. Much of the church meets in homes, and many believers come from Muslim backgrounds. Across the region, ministry leaders report Muslims describing dreams and visions of Jesus (our report).
- Algeria. With nearly all Protestant churches sealed, believers gather in homes, garages and outdoors (our report).
- Malaysia. Malay converts can't legally leave Islam, so many live a double life, worshipping where no ID is checked.

Why Believers Choose It
Underground churches usually exist for one of three reasons:
- Worship is illegal or banned outright.
- Registration comes with control — over what can be preached, who can attend (often no children) or how the church relates to the state — and believers won't accept it.
- Converts face danger from family, community or authorities, so gathering publicly would expose them.
Their answer echoes the apostles: "We must obey God rather than human beings!" (Acts 5:29).
How They Survive — and Grow
House churches stay small so they can move. Leaders train other leaders, Scripture is shared on phones and memorised, and groups multiply rather than grow large. The pressure is real — arrests, raids, sealed buildings, lost jobs — yet in several of these places the church has grown under it, much as it did in the book of Acts, where persecution scattered believers who "preached the word wherever they went" (Acts 8:4).
How to Stand With the Underground Church
- Pray specifically. Name countries, churches and leaders. Our guide on how to pray for the persecuted church is built around what believers under pressure actually ask for — and the first request is usually that the church elsewhere wouldn't forget them.
- Stay informed. Follow their stories; we keep them on our Christian persecution page.
- Support Scripture access. More than 500 million Christians live where access to the Bible is restricted.
- Give thanks for your freedom — and use it. Gather, worship and share your faith openly, for those who can't.

Biblical Perspective
The first Christians met house to house (Acts 2:46; Romans 16:5). When ordered to stop teaching in Jesus' name, the apostles answered, "We must obey God rather than human beings!" (Acts 5:29), and persecution scattered believers who "preached the word wherever they went" (Acts 8:4). Scripture calls the wider church to "remember those in prison as if you were together with them in prison" (Hebrews 13:3).
"Continue to remember those in prison as if you were together with them in prison, and those who are mistreated as if you yourselves were suffering."
— Hebrews 13:3 (NIV)
Pray With Us
Lord, we pray for Your church meeting in secret — in China, North Korea, Iran, Algeria, Malaysia and every hidden place. Protect believers from raids and betrayal, strengthen leaders in prison, and give them Scripture, courage and joy. Multiply their small gatherings. Help us never to forget them, and to use our freedom well. In Jesus' name, amen.
