ChristadelphiansThe Christadelphians (ˌkrɪstəˈdɛlfiənz) are a restorationist group that hold a view of biblical unitarianism. There are approximately 50,000 Christadelphians in around 120 countries. The movement developed in the United Kingdom and North America in the 19th century around the teachings of John Thomas, who coined the name Christadelphian from the Greek words for Christ (Christos) and brothers (adelphoi). Asserting the Bible as the sole basis of their beliefs, Christadelphians differ from mainstream Christianity in a number of doctrinal areas.
Restoration MovementThe Restoration Movement (also known as the American Restoration Movement or the Stone–Campbell Movement, and pejoratively as Campbellism) is a Christian movement that began on the United States frontier during the Second Great Awakening (1790–1840) of the early 19th century. The pioneers of this movement were seeking to reform the church from within and sought "the unification of all Christians in a single body patterned after the church of the New Testament.
SocinianismSocinianism (səˈsɪniənɪzəm) is a Nontrinitarian Christian belief system developed and co-founded during the Protestant Reformation by the Italian Renaissance humanists and theologians Lelio Sozzini (Latin: Laelius Socinus) and Fausto Sozzini (Latin: Faustus Socinus), uncle and nephew, respectively. It was developed among the Polish Brethren in the Polish Reformed Church between the 16th and 17th centuries, and embraced by the Unitarian Church of Transylvania during the same period.
NontrinitarianismNontrinitarianism is a form of Christianity that rejects the mainstream Christian theology of the Trinity—the belief that God is three distinct hypostases or persons who are coeternal, coequal, and indivisibly united in one being, or essence (from the Ancient Greek ousia). Certain religious groups that emerged during the Protestant Reformation have historically been known as antitrinitarian.
