Henotheism, or worship of one supreme deity, is defined as the worship of this god. Friedrich Schelling & Friedrich Welcker were the first to coin this term in order to describe primitive monotheism among ancient Greeks. A person who believes in henotheism doesn't deny the existence and power of lower deities.
Hinduism
Hinduism is monotheistic religion that believes in a supreme spirit that lives in all creatures. Hindus seek to attain "moksha", a state of absolute salvation. Moksha means that an individual is free from the cycle of rebirth and can be considered an absolute soul. Hindus also believe that karma is the belief in which the spiritual ramifications one's actions have a cyclical balance.
Hinduism, though monotheistic, is often viewed as a polytheistic religion. While this does not mean Hindus aren't religious believers in other gods or worship them, it does indicate that they do not believe in them. Hindus see their gods to be personifications for a unifying force. Hindus believe Jesus is a manifestation the gods.
Hinduism is the third most-popular religion in the world. The majority of its followers live in India. It differs from Abrahamic religions in that it has no identifiable founder and no central religious authority. However, it recognizes other gods as well as believes in the afterlife.
Greco-Roman religion
The Romans and Greeks of ancient Greece worshipped Gods every day. They also celebrated important life events with religious rituals. The ancient cultures believed that there were many gods, each with different powers. Roman gods focussed on raw power, while Greek gods believed they could find balance between law (nature) and law (law). They also included foreign deities into their pantheon.
Greek philosophy emphasized the need for logical reasoning and reasoned questions. It was the first attempt to present rational explanations for the origin and nature of the universe. The Milesian School was a precursor of Greek philosophy, and sought an underlying element that formed all matter. Later, the Stoic school added ethical, political, and social theories to the philosophy that had been developed previously. This philosophy was the basis of Western philosophy.
Henotheism combines the idea of the unity of God with the idea that God exists in many forms. Although the gods can take many forms, they all share the same firstness. This is the core tenet henotheism. While henotheism was present in paganism and early Christianity, it gradually fell into disuse after the twenties.
Assyrian religion
In the Neo-Assyrian Empire, Assyrian Henotheistic religious traditions developed. Assur was the supreme god of the Assyrians, and his role as a god was viewed as ideal. Assur's philosophy was informed by Marduk and Ellil, which Assyrian philosophers also incorporated. Asshur, the supreme god of the Assyrians, determined human destiny in the distant future, and was the ultimate awe-inspiring figure.
The Assyrians ruled over an area that included modern Turkey and northern Mesopotamia. The Assyrian empire grew to its zenith during Ashurbanipal's reign (ca. 1750 BC), and started to fall apart. After the death of Ashurbanipal, more areas of the empire broke away. The Assyrians gave up to an alliance consisting of nations in 612 BCE. Over 500 years, the Kassites ruled this region.
These myths were based on a democratic pantheon. The gods negotiated over matters of the universe, but eventually one supreme god emerged. Babylon's Marduk was the local god of Babylon and rose to the level of god according to Babylonian mythology. He was granted greater powers and attributes as a result.
