According to Wikipedia: "Unitarianism as a theology is the belief in the single personality of God, in contrast to the doctrine of the Trinity (three persons in one God).[1] It is the philosophy upon which the modern Unitarian movement was based, and, according to its proponents, is the original form of Christianity. Unitarian Christians believe in the teachings of Jesus Christ, as found in the New Testament and other early Christian writings, and hold him up as an exemplar. Adhering to strict monotheism, they maintain that Jesus was a great man and a prophet of God, perhaps even a supernatural being, but not God himself. Unitarians believe in the moral authority, but not necessarily the divinity, of Jesus. Their theology is thus distinguishable from the theology of Catholic, Orthodox, Anglican, mainline Protestant, and other Christian denominations which hold the Trinity doctrine as a core belief."
