House church in the context of "Early Christian"

A church, church building, or chapel is a building used for Christian worship services and Christian activities. The earliest identified Christian church is a house church founded between 233 AD and 256 AD. The word church also describes a body or assembly of Christian believers, while "the Church" refers to the worldwide Christian religious community.

In traditional Christian architecture, the plan view of a church often forms a Christian cross. The center aisle and seating create the vertical beam, while the bema and altar form the horizontal arms. Towers or domes rise above the heaven-facing roof line to encourage contemplation of the divine. Modern churches employ varied architectural styles, and many buildings originally designed for other purposes have been converted to churches. From the 11th to the 14th centuries, Western Europe experienced a wave of church construction.

Early Christianity, otherwise called the Early Church, describes the historical era of the Christian religion up to the First Council of Nicaea in 325. Christianity spread from the Levant, across the Roman Empire, and beyond. Originally, this progression was closely connected to already established Jewish centers in the Holy Land and the Jewish diaspora throughout the Eastern Mediterranean. The first followers of Christianity were Jews who had converted to the faith, i.e. Jewish Christians, as well as Phoenicians, i.e. Lebanese Christians. Early Christianity contains the Apostolic Age and is followed by, and substantially overlaps with, the Patristic era.

The Apostolic sees claim to have been founded by one or more of the apostles of Jesus, who are said to have dispersed from Jerusalem sometime after the crucifixion of Jesus, c. 26–33, perhaps following the Great Commission. Early Christians gathered in small private houses, known as house churches, but a city's whole Christian community would also be called a "church"—the Greek noun ἐκκλησία (ekklesia) literally means "assembly", "gathering", or "congregation" but is translated as "church" in most English translations of the New Testament.

The Epistle to Philemon is a Pauline epistle of the New Testament of the Christian Bible. It is a prison letter, authored by Paul the Apostle (the opening verse also mentions Timothy), to Philemon, a leader in the Colossian church. Paul does not identify himself as an apostle with authority, but as "a prisoner of Jesus Christ", calling Timothy "our brother", and addressing Philemon as "fellow labourer" and "brother" (Philemon 1:1; 1:7; 1:20). Onesimus, a slave who had escaped from his master Philemon, was returning with this epistle wherein Paul asked Philemon to receive him as a "brother beloved" (Philemon 1:9–17). The letter appeals on behalf of Onesimus, who had subsequently became a Christian through Paul. Paul requests that Philemon receive Onesimus not as a slave but as a beloved brother in Christ, offering to repay any debt Onesimus owes.

Philemon was a wealthy Christian, possibly a bishop of the church that met in his home (Philemon 1:1–2) in Colossae. This letter is now generally regarded as one of the undisputed works of Paul. It is the shortest of Paul's extant letters, consisting of only 335 words in the Greek text.
