Ethical monotheism is a form of exclusive monotheism in which God is the source for one standard of morality, who guides humanity through ethical principles.
Ethical monotheism originated within non-missionizing Judaism to the exclusion of other gods or higher powers in the biblical period. It is evident in many different religions, such as Zoroastrianism, Christianity, Islam, Bahá'í Faith, Sikhism, and many more; all of these religions carry the belief of having one sole higher power, who controls everything that occurs in the world.
Originally, ethical monotheism implied the adherence to the non-physical, non-corporeal, eternal, and in no way anthropomorphic "God of Abraham, God of Isaac, and God of Jacob" (Elohei Avraham, Elohei Yitzchak ve Elohei Ya`aqov). This original form of ethical monotheism is based on practice, tradition and—to some—the logical result of questions concerning the origin of the world, rather than arrived at as the conclusion of a philosophical argument. The worship of other gods that were not present at the revelation on Mount Sinai, in particular the God in Christianity, is referred to as avodah zarah in Judaism, and it is traditionally believed that there are neither other pagan gods nor other (incarnated) divine personages.
The God of ethical monotheism is worshiped in Islam and in Bahá'í Faith, but can also be the Zoroastrian higher divine uncreated spirit named Ahura Mazda, and in Sikhism the Supreme Being or the creator of all named Waheguru. In Christianity the original God of ethical monotheism is worshiped as part of the Trinity, or as part of non-trinitarian conceptions of God. Other gods are variously considered to be false or demonic, and it is believed that any other gods cannot be compared to the one true God.
