Deity | Definition, Examples, Major Religions, & Facts | Britannica (2024)

deity, a god, goddess, or other supernatural being considered divine. While not all religions involve deities, deities are central to most of the world’s largest religions today. The exact qualities of a deity will vary from one belief system to another, but they generally have powers and knowledge far beyond those of humanity, often including omnipotence and omniscience.

Because deities are conceived of so differently by different cultures, and even by different belief systems and traditions within cultures, it is difficult to describe them generally. In some religions deities are immortal and eternal, while in others they are merely long-lived and changeable. In some religions one deity encompasses all of existence, while in others nature is ruled by a wide variety of lesser deities. In some religions deities are fundamentally good, while in others they have all the moral failings of humans or the indifference of nature itself. In some religions a deity may exist outside the physical universe, while in others they are tied to material objects. A deity is a spiritual being that is held as sacred, more deeply important and worthy of worship than mundane reality.

The belief in a deity or multiple deities is often described as theism. However, theism can also refer to a specific religious proposition that all worldly things depend on the existence of a single supreme deity that is personally involved in the world. It can be contrasted with deism, the belief in a creator deity that is not involved in the world created, or pantheism, in which the deity is synonymous with the universe rather than supreme over it.

Religions that include deities are sometimes called theistic religions (though this term also has more specialized uses). They are frequently divided into categories on the basis of their views on the nature of deities, most notably whether there is a single supreme god or goddess or whether there are multiple gods and goddesses. Monotheistic religions are those in which there is only one god or goddess, and polytheistic religions are those in which there are multiple gods or goddesses. However, the distinction between monotheism and polytheism can sometimes be complicated, as deities are not defined by physical, earthly traits and may have more complicated natures, as with the Christian Trinity or the Hindu brahman.

In monotheistic religions, adherents worship a single supreme deity who is usually the source of all existence as we know it. The deity in monotheistic religions is often considered omnipotent (all-powerful), omniscient (all-knowing), and omnibenevolent (perfectly good). In some traditions a monotheistic deity may be a creator who rules over the universe. In pantheistic belief systems the deity is a universal spirit that is one with the universe itself, while in panentheistic traditions the universe is a mere part of the creator deity, who transcends the universe itself. Monotheists may view their supreme deity as immanent, meaning that it manifests in the physical universe, or transcendent, meaning that it exists outside the physical universe, or both.

In polytheistic religions, adherents recognize the existence of at least two deities. These deities may form a pantheon, as in Greek mythology. In some religions, the deities may be dualistic in nature, meaning the divine forces compete or complement each other, as in most gnostic and Zoroastrian traditions. Polytheistic deities are by necessity less likely to possess omnipotence or omniscience, though in many traditions there is a supreme deity, such as the Greek Zeus, who is above the other gods and goddesses and may be termed omnipotent due to unmatched (but not strictly limitless) power. Some Buddhist traditions, in contrast, hold that deities are transient and subordinate to the greater spiritual reality of the universe. In some cases, though the existence of many gods is recognized, one deity is considered most worthy of worship, such as in certain interpretations of Zoroastrianism. In other cases, such as in Shintō, there may be an abundance of local deities worshipped by individual tribes, cities, or villages.
