Monolatrism

Monolatrism or monolatry (Greek: μόνος (monos) = single, and λατρεία (latreia) = worship) is recognition of the existence of many gods but with the consistent worship of only one deity. The term was perhaps first used by Julius Wellhausen.

Monolatry is distinguished from monotheism, which asserts the existence of only one god, and henotheism, a religious system in which the believer worships one god without denying that others may worship different gods with equal validity.
