Monotheism

Monotheism, the term usually employed to denote a belief in the unity of the Godhead, or belief in and worship of one God. It is thus the opposite of Polytheism. The doctrine of the Trinity is thought by some (e.g. the Unitarians) to be incompatible with the monotheism taught by Jesus Christ, and is therefore rejected as no part of His teaching. Mohammedans and Jews, of course, reject with vehemence the least approach to a Trinitarian conception of the Deity.
