Henotheism is the worship of one supreme God. Friedrich Schelling & Friedrich Welcker were the first to coin this term in order to describe primitive monotheism among ancient Greeks. A person who follows henotheism does not deny the existence of lower deities.
Hinduism
Hinduism is monotheistic religion that believes in a supreme spirit that lives in all creatures. The highest goal of a Hindu is to attain "moksha" (saved state). Upon attaining moksha, an individual is exempt from rebirth and becomes part of an absolute soul. Hindus believe in karma. It is believed that one's spiritual ramifications will be balanced cyclically.
Hinduism is a monotheistic religion, although it's often perceived as a polytheistic religion. Although Hindus may believe in other gods, they don't worship these. They view their gods as personifications a unifying power. Hindus believe Jesus is a manifestation these gods.
Hinduism is the third most-popular religion in the world. The majority of its followers live in India. It is unique among Abrahamic religions in the fact that it has no identified founder or central religious authority. However, it believes in the afterlife and recognizes other gods.
Greco-Roman religion
In ancient Greece, both Romans (and Greeks) worshipped gods every single day. Major life events were celebrated with religious rituals. There were many gods in ancient cultures, each with their own powers. Roman gods emphasized raw power while Greek gods believed in balance between law, nature, and law. They also included foreign gods into the pantheon.
Greek philosophy stressed logic and reasoned questions. It was one of the earliest attempts at presenting rational explanations of the nature and origin of the universe. The Milesian School, a precursor to Greek philosophy, sought the underlying element that created all matter. Later, the Stoic school added social, political and ethical theories to the philosophy already developed. This philosophy was the basis of Western philosophy.
Henotheism is a combination of the idea of God's unity and the belief that God exists in many different forms. Although the gods can take many forms, they all share the same firstness. This is the central tenet in henotheism. Although henotheism was a part of early Christianity and paganism, it slowly fell out of favor in the twenties.
Assyrian religion
The Neo-Assyrian Empire was the birthplace of the Assyrian henotheistic religious religion. Assur was the Assyrian god supreme and his role as god was considered to be ideal. Assur's cosmology was influenced by the Assyrian philosophers Marduk, Ellil. Asshur, the Assyrian supreme god, decided human destiny in the far future and was an awe-inspiring figure.
The Assyrians ruled over a region that included modern-day Turkey and northern Mesopotamia. The Assyrian empire grew to its zenith during Ashurbanipal's reign (ca. 1750 BC) and then began to unravel. Ashurbanipal died, and more parts of the empire fell apart. In 612 BCE the Assyrians lost to an alliance made up of nations. For more than 500 years, the Kassites ruled the area.
The myths surrounding these ancient civilizations reflected a democratic pantheon of gods. Over the affairs of the universe, many gods worked together to create one supreme God. Babylon's local god Marduk rose to the rank of god in Babylonian mythology. He was granted greater powers and attributes as a result.
