Origin and history: The Unitarian Universalist denomination, as its name suggests, believes in the unitary nature of God. Unlike most Christian sects, it rejects the concept of the trinity or the idea that God is made up of the Father, the Son and the Holy Spirit. Although the modern Unitarian Universalist Association was founded in 1961, the denomination has a long history in America. Unitarians stood out from other religious groups early in their history because they believed in universal salvation, in contrast to Calvinists who believed in the possibility of salvation only for a small, select group of people. The Unitarian Universalist Association (UUA) unifies two religious movements, that of Unitarianism (believers in the unity of God) and Universalists (believers in universal salvation). The idea of ​​a "unitary" Christian God has origins that date back to the first Christian fathers. Origen of Alexandria and Gregory of Nyssa supported the idea of ​​a singular deity, although the Council of Nicaea declared the idea heretical in 325 BCE. (Unitarian Universalism) Another early supporter of Unitarianism, Michael Servetus was martyred in 1553 during the Reformation “for his criticism of the doctrine of the trinity and his opposition to infant baptism… Servetus rejected the doctrine of original sin and the entire theory of salvation based on it, including the doctrines of the dual nature of Christ and the vicarious atonement effected by his death. He believed that Jesus had a nature, both fully human and divine, and that Jesus was not another being of divinity separate from the Father, but God come to earth. Other human beings, touched by Christian grace, might overcome sin and become progressively divine themselves” (Hughes)...... half of the paper ......alism in America, A Documentary History.
