Monotheism is the belief in one god.[1][2][3][4] A narrower definition of monotheism is the belief in the existence of only one god that created the world, is omnipotent, omnipresent and omniscient.[5][6][7]

A distinction may be made between exclusive monotheism, and both inclusive monotheism and pluriform (panentheistic) monotheism which, while recognising various distinct gods, postulate some underlying unity.[1]

Monotheism is distinguished from henotheism, a religious system in which the believer worships one god without denying that others may worship different gods with equal validity, and monolatrism, the recognition of the existence of many gods but with the consistent worship of only one deity.[8] The term monolatry was perhaps first used by Julius Wellhausen.[9]

The broader definition of monotheism characterizes the traditions of Bábism, the Baháʼí Faith, Cao Dai (Caodaiism), Cheondoism (Cheondogyo), Christianity,[10] Deism, Druze faith,[11] Eckankar, Sikhism, Hindu sects such as Shaivism and Vaishnavism, Islam, Judaism, Mandaeism, Rastafari, Seicho no Ie, Tenrikyo (Tenriism), Yazidism, and Zoroastrianism, and elements of pre-monotheistic thought are found in early religions such as Atenism, ancient Chinese religion, and Yahwism.[1][12]
