Unitarianism (from Latin unitas "unity, oneness", from unus "one") is a Christian theological movement named for its belief that the God in Christianity is one person, as opposed to the Trinity (tri- from Latin tres "three") which in most other branches of Christianity defines God as one being in three persons: the Father, Son, and Holy Spirit.[1] Unitarian Christians, therefore, believe that Jesus was inspired by God in his moral teachings, and he is a savior,[2][3] but he was not a deity or God incarnate. As is typical of dissenters, Unitarianism does not constitute one single Christian denomination, but rather refers to a collection of both existing and extinct Christian groups, whether historically related to each other or not, which share a common theological concept of the oneness nature of God. Unitarian communities have developed in Britain, South Africa, India, Canada, the United States, Jamaica, Nigeria, and Japan.
