A house church or home church is a label used to describe a group of Christians who regularly gather for worship in private homes. The group may be part of a larger Christian body, such as a parish, but some have been independent groups that see the house church as the primary form of Christian community.

Some recent Christian writers like Francis Chan have supported the view that the Christian Church should meet in houses, and have based the operation of their communities around multiple small home meetings. Other Christian groups choose to meet in houses when they are in the early phases of church growth or when membership is small, because a house is the most affordable option for the small group to meet until the number of people attending the group is sufficient to warrant moving to a commercial location such as a church building. (as in the beginning phase of the British New Church Movement). Sometimes this meeting style is advantageous because the group is a member of a Christian congregation which is otherwise banned from meeting as is the case in China and Iran. House church organizations claim that this approach is preferable to public meetings in dedicated buildings because it is a more effective way of building community and personal relationships, and it helps the group to engage in outreach more naturally. Some believe small churches were a deliberate apostolic pattern in the first century, and they were intended by Christ.

Origins In the early church, Christian fellowship, prayer, and service took place mainly in private homes, as described in the book of Acts of the Apostles.Philip Carrington, The Early Christian Church: Volume 1, The First Christian Century, Cambridge University Press, UK, 2011, p. 41-42 The Latin term often used is domus ecclesiae.Encyclopædia Britannica online version.

Several passages in the New Testament specifically mention churches meeting in houses. The first house church is recorded in Acts 1:13, where the disciples of Jesus met together in the "Upper Room" of a house, traditionally believed to be where the Cenacle is today. "The churches of Asia greet you, especially Aquila and Prisca greet you much in the Lord, along with the church that is in their house." I Corinthians 16:19. The church meeting in the house of Priscilla and Aquila is again mentioned in Romans 16:3, 5. The church that meets in the house of Nymphas is also cited in the Bible: "Greet the brethren in Laodicea, and Nymphas, and the church which is in her house." Colossians 4:15. There is another reference to the church meeting in Philemon's home ("To Philemon our dear friend and fellow worker—also to Apphia our sister and Archippus our fellow soldier—and to the church that meets in your home:...." Philemon 1:2), but scholars recognize this as simply the meeting place of the Corinthian church—not a separately-meeting house church.

For the first 300 years of Early Christianity, until Constantine legalized Christianity and churches moved into larger buildings, Christians typically met in homes, if only because intermittent persecution (before the Edict of Milan in 313) did not allow the erection of public church buildings.George Thomas Kurian, Mark A. Lamport, Encyclopedia of Christianity in the United States, Volume 5, Rowman & Littlefield, USA, 2016, p. 1142. Clement of Alexandria, an early church father, wrote of worshipping in a house. The Dura-Europos church, a private house in Dura-Europos in Syria, was excavated in the 1930s and was found to have been used as a Christian meeting place in AD 232, with one small room serving as a baptistry creating the current style church seen today.

Modern History During the 20th and 21st centuries, in some countries of the world which apply sharia law or have communist governments, government authorizations for worship are complex for Christians.Erwin Fahlbusch, Geoffrey William Bromiley, The Encyclopedia of Christianity, Volume 4, Wm. B.

In China

In the People's Republic of China (PRC), house churches or family churches () are Protestant assemblies that operate independently from the state-sanctioned Three-Self Patriotic Movement (TSPM) and China Christian Council (CCC), and came into existence due to the change in religious policy after the end of the Cultural Revolution in the early 1980s. The TSPM was set up after the Communist Party established the PRC in 1949, for Protestants to declare their patriotism and support of the new government. However, by the time of the Cultural Revolution (1966–1976), all public religious practice came to an end; the government of the People's Republic of China officially espouses state atheism, and has conducted antireligious campaigns to this end. Many churches, temples and mosques were destroyed during the Cultural Revolution, which also criminalized the possession of religious texts. Due to the changes in religious policy after the end of the Cultural Revolution, in 1980, the TSPM was reinstated and the China Christian Council was formed. Protestant congregations that wished to worship publicly registered with the TSPM, but those that did not were eventually termed house churches.

Revivals Recent developments in the house church movement in North America and the United Kingdom are often seen as a return to a New Testament church restorationist paradigm, a restoration of God's eternal purpose, and the natural expression of Christ on Earth, urging Christians to reject hierarchy and rank, and return to practices described and encouraged in Scripture. According to some proponents, many churchgoers are turning to house churches because traditional churches fail to meet their relational needs and are not representative of the structure exhibited throughout the Acts of the Apostles and Epistles of the New Testament.

Some authors who are often associated with "house church" by others (for example Jon Zens and Frank Viola) consider the term "house church" to be a misnomer, asserting that the main issue for Christians who gather together is not the location of the meeting, but whether or not Jesus Christ is the functional head of the gathering and face-to-face community is occurring. Other names which may be used to describe these kinds of churches simple church, "relational church", "primitive church", "body life", "organic church" or "biblical church". Some authors do not believe "house church" or "organic church" are "movements", and they distinguish between a house church/simple church and an organic expression of the church.

House churches can adopt an organic church philosophy, which is not necessarily a particular method, technique or movement, but rather a particular church expression that the group takes on when the organization is functioning according to the pattern of a living organism. The church represented in the New Testament is based on this principle, and both traditional & contemporary versions of "Westernized" Christianity has reversed this order.

The origins of the modern house church movement in North America and the UK are varied. Some have viewed it as a development and logical extension of the Plymouth Brethren movement, both in doctrine and practice. Many individuals and assemblies have adopted new approaches to worship and governance, while others recognize a relationship to the Anabaptists, the Free Christians, the Quakers, the Amish, the Hutterites, the Mennonites, the Moravians, the Methodists, the much earlier conventicles movement, the Waldenses or the Priscillianists. Another perspective sees the house church movement as a re-emergence of the move of the Holy Spirit during the Jesus Movement of the 1970s in the US or the worldwide Charismatic Renewal of the late 1960s and 1970s. Others believe that the House Church movement was pioneered by the Reverend Ernest Southcott in the 1950s, when he was Vicar of St Wilfred's Church in Halton, Leeds, in England. Southcott believed that if people would not come to church, the church must go to the people, and his book The Parish Comes Alive spread this idea widely among Anglicans.The Parish Comes Alive by Ernie Southcott, London: Mowbray, 1961

Limited financial resources can encourage church leaders to rethink the pattern of ministry and look for ways to forward the outreach of the church with unpaid members.

Simple church The simple church is an Evangelical Christian movement that reinterprets the nature and practice of church. A simple church may meet anywhere with or without trained leaders, formal liturgy, programs or structures.House2House Magazine Website, "What Do We Mean By Simple Church To facilitate relationship, discipleship (spiritual formation), multiplication, mobility, and member ownership, a simple church is usually a small group of no more than 20–25 persons. Most Church "programs" privately meet during some days of the week and discuss troubles that they are having with their faith, and personal life. Church "programs" are virtually nonexistent and small group participation is essential. The process of moving from worship to small group, small group to mission work, and mission work to worship is a primary focus.

Authors Tony and Felicity Dale, founders of House2House Ministries, have promoted the term "simple church" in their book "Simply Church".Dale, T. and Dale, F. (2000) Simply Church. Karis Books, What We Do: Planting Simple Churches The term is often used interchangeably with other terms like organic church,Cole, N. (2005) Organic Church: Growing faith where life happens. John Wiley & Sons, essential church, primitive church, bodylife, relational church, and micro-church.Larry Kreider, "House Churches & Micro Churches" (Accessed 29 September 2006)

In the early twenty-first century a number of established Christian denominations and mission organizations have officially supported efforts to develop house church networks.

Origins and influences The simple church movement is part of the broader house church movement. Simple church has also been influenced by overseas missions and the growth of church planting movements.See David Garrison, "Church Planting Movements" (International Missionary Board Southern Baptist Convention, 2004); and Rad Zdero, "The Global House Church Movement" (William Carey Library Publishers, 2004, ). Church planting movements are spontaneously growing church multiplication efforts.

The missional Movement has also influenced simple church.

Values As in any decentralized, spontaneous movement, a variety of values are expressed in simple church. Due to the influence of some key groups and Acts 2:42–47, three overarching values have emerged in many circles. Adherents Paul Kaak (who began ministry in one of the largest and most systematized mega-churches in America) and Neil Cole originally articulated these values using the letters DNA. According to him:
