Unitarianism is historically a Christian theological movement named for the affirmation that God is one entity, in direct contrast to Trinitarianism, which defines God as three persons in one being. Traditional Unitarians maintain that Jesus of Nazareth is in some sense the "son" of God (as all humans are children of the Creator), but that he is not the one God himself. They may believe that he was inspired by God in his moral teachings and can thus be considered a savior, but all Unitarians perceive Christ as human rather than a Deity. Unitarianism is also known for the rejection of several other Western Christian doctrines, including the soteriological doctrines of original sin and predestination, and, in more recent history, biblical inerrancy. Unitarians in previous centuries accepted the doctrine of punishment in an eternal hell, but few do today.
