Monolatry (Ancient Greek: μόνος, romanized: monos, lit. 'single', and λατρεία, latreia, 'worship') is the belief in the existence of many gods, but the insistence on the exclusive worship of only a single chosen deity. The term was possibly first used by Julius Wellhausen.
Monolatry is distinguished from monotheism, which asserts the existence of only one god, and henotheism, which accepts both the existence of other gods and the validity of their worship.
