Arianism is a Christological doctrine considered heretical by all mainstream branches of Christianity. It is first attributed to Arius, a Christian presbyter who preached and studied in Alexandria, Egypt. Arian theology holds that Jesus Christ is the Son of God, who was begotten by God the Father with the difference that the Son of God did not always exist but was begotten/made before time by God the Father; therefore, Jesus was not coeternal with God the Father, but nonetheless Jesus began to exist outside time as time applies only to the creations of God.
A creed, also known as a confession of faith, a symbol, or a statement of faith, is a statement of the shared beliefs of a community in a form which is structured by subjects which summarize its core tenets.
In Christianity, Christology, translated from Greek as 'the study of Christ', is a branch of theology that concerns Jesus. Different denominations have different opinions on questions such as whether Jesus was human, divine, or both, and as a messiah what his role would be in the freeing of the Jewish people from foreign rulers or in the prophesied Kingdom of God, and in the salvation from what would otherwise be the consequences of sin.
The Christian countercult movement or the Christian anti-cult movement is a social movement among certain Protestant evangelical and fundamentalist and other Christian ministries and individual activists who oppose religious sects that they consider cults.
Gilbert Keith Chesterton was an English writer, philosopher, Christian apologist, and literary and art critic.
Apologetics is the religious discipline of defending religious doctrines through systematic argumentation and discourse. Early Christian writers who defended their beliefs against critics and recommended their faith to outsiders were called Christian apologists. In 21st-century usage, apologetics is often identified with debates over religion and theology.
Orthodoxy is adherence to correct or accepted creeds, especially in religion.
Father Brown is a fictional Roman Catholic priest and amateur detective. He is featured in 53 short stories by English author G. K. Chesterton, published between 1910 and 1936. Father Brown solves mysteries and crimes using his intuition and keen understanding of human nature. Chesterton loosely based him on the Rt Rev. Msgr John O'Connor (1870–1952), a parish priest in Bradford, who was involved in Chesterton's conversion to Catholicism in 1922. Since 2013, the character has been portrayed by Mark Williams in the ongoing BBC Television Series Father Brown.
Christian tradition is a collection of traditions consisting of practices or beliefs associated with Christianity. These ecclesiastical traditions have more or less authority based on the nature of the practices or beliefs and on the group in question. Many churches have traditional practices, such as particular patterns of worship or rites, that developed over time. Deviations from such patterns are sometimes considered unacceptable by followers or are regarded as heretical. There are certain Christian traditions that are practiced throughout the liturgical year, such as praying a daily devotional during Advent, erecting a nativity scene during Christmastide, chalking the door on Epiphany Day, fasting during Lent, waving palms on Palm Sunday, eating easter eggs during Eastertide, and decorating the church in red on Pentecost.
Christian apologetics is a branch of Christian theology that defends Christianity.
Conservative Christianity, also known as conservative theology, theological conservatism, traditional Christianity, or biblical orthodoxy is a grouping of overlapping and denominationally diverse theological movements within Christianity that seeks to retain the orthodox and long-standing traditions and beliefs of Christianity, it is contrasted with Liberal Christianity and Progressive Christianity which are seen as heretical heterodoxies by theological conservatives. Conservative Christianity should not be mistaken as being synonymous with the political philosophy of conservatism nor the Christian right which is a political movement of Christians who support conservative political ideologies and policies within the realm of secular or non-sectarian politics. The two major subdivisions of Conservative Christianity within Protestantism are Evangelical Christianity and Christian Fundamentalism while the Confessing Movement, Confessionalism, and to an extent Neo-orthodoxy make up the remaining within Protestantism. Theological conservatism is also found in Roman Catholicism and is also found within Eastern Orthodoxy, Oriental Orthodoxy, the Church of the East; and throughout all of Mainstream-Nicene Christianity in both Western Christian and Eastern Christian traditions, although not every community has had a direct connection with the Fundamentalist–Modernist controversy.
The New Apostolic Reformation (NAR) is a movement which seeks to establish a fifth branch within Christendom distinct from Catholicism, Protestantism, Oriental Orthodoxy, and Eastern Orthodoxy. The NAR movement largely consists of churches nominally or formerly associated with Pentecostal denominations and Charismatic movements but have diverged from traditional or classical Pentecostal and Charismatic theology in that it advocates for the restoration of church governance by the lost offices of prophet and apostle, which they believe were lost in the first centuries of Christianity in favor of pastors, elders, and administrators.
The Everlasting Man is a Christian apologetics book written by G. K. Chesterton, published in 1925. It is, to some extent, a deliberate rebuttal of H. G. Wells' The Outline of History, disputing Wells' portrayals of human life and civilisation as a seamless development from animal life and of Jesus Christ as merely another charismatic figure. Chesterton detailed his own spiritual journey in Orthodoxy, but in this book he tries to illustrate the spiritual journey of humanity, or at least of Western civilisation. The author Ross Douthat credits that, "Chesterton's somewhat loosey-goosey outline of history doubles as the best modern argument for Christianity I've ever read. You have to give in to the Chestertonian style, but if you do, be careful—you might just be converted."
Branch theory is an ecclesiological proposition that the One, Holy, Catholic, and Apostolic Church includes various different Christian denominations whether in formal communion or not. The theory is often incorporated in the Protestant notion of an invisible Christian Church structure binding them together.
Heresy in Christianity denotes the formal denial or doubt of a core doctrine of the Christian faith as defined by one or more of the Christian churches.
Christianity in late antiquity traces Christianity during the Christian Roman Empire — the period from the rise of Christianity under Emperor Constantine, until the fall of the Western Roman Empire. The end-date of this period varies because the transition to the sub-Roman period occurred gradually and at different times in different areas. One may generally date late ancient Christianity as lasting to the late 6th century and the re-conquests under Justinian of the Byzantine Empire, though a more traditional end-date is 476, the year in which Odoacer deposed Romulus Augustus, traditionally considered the last western emperor.
Heretics is a collection of 20 essays by English writer G. K. Chesterton published by John Lane in 1905.
The theology of John Calvin has been influential in both the development of the system of belief now known as Calvinism and in Protestant thought more generally.
