Christology

Unitarians charge that the Trinity, unlike unitarianism, fails to adhere to strict monotheism. Unitarians maintain that Jesus was a great man and a prophet of God, perhaps even a supernatural being, but not God himself. They believe Jesus did not claim to be God and that his teachings did not suggest the existence of a triune God.

Unitarian Christology can be divided according to whether or not Jesus is believed to have had a pre-human existence. Both forms maintain that God is one being and one person and that Jesus is the (or a) Son of God, but generally not God himself.

In the early 19th century, Unitarian Robert Wallace identified three particular classes of Unitarian doctrines in history:

Unitarianism is considered a factor in the decline of classical deism because there were people who increasingly preferred to identify themselves as Unitarians rather than deists.

Several tenets of Unitarianism overlap with the predominant Muslim view of Jesus and Islamic understanding of monotheism.
