“Who is God?” does not have one answer shared by every religion. Some traditions describe one personal Creator, some speak of ultimate reality in several ways, and some do not place a creator deity at the center of religious life.
God in Judaism, Christianity, and Islam
Judaism teaches one God, the Creator of the world and the God of Israel’s covenant. Jewish tradition uses several names and titles for God while treating the divine name with particular reverence.
Christianity also teaches one God, understood as Father, Son, and Holy Spirit. This doctrine of the Trinity does not mean three gods; classical Christian theology describes one divine being in three persons. Jesus Christ is understood by mainstream Christianity as the incarnate Son of God.
Islam teaches absolute divine unity, known as tawhid. The Arabic word Allah simply means God. Muslims believe that God is the Creator, merciful and just, and unlike created things. Islamic theology rejects the idea that God has partners or is divided into persons.
Sikh and Hindu understandings
Sikhism begins with the affirmation of one ultimate reality, commonly expressed as Ik Onkar. God is described as one, eternal, without fear or hatred, and beyond limitation, while also known through divine names and devotion.
Hindu traditions are highly diverse. Some schools emphasize Brahman as ultimate reality. Some worship Vishnu, Shiva, Devi, Krishna, or other deities as the supreme personal form of the divine. Other schools interpret the relationship between the individual self, the world, and ultimate reality in different ways. It is therefore misleading to reduce Hinduism to either simple monotheism or simple polytheism.
Buddhism and non-creator traditions
Buddhism does not generally center on belief in a creator God. Buddhist texts include devas and other non-human beings, but these beings are also part of conditioned existence and are not treated as creators of the universe. The central Buddhist concern is awakening from suffering through ethics, meditation, and wisdom.
Jainism also does not teach a creator God in the Abrahamic sense. Many Indigenous and traditional religions understand sacred power, spirits, ancestors, or divine beings through frameworks that do not fit neatly into Western categories of monotheism and polytheism.
Why the word “God” can be difficult to compare
Religions use different languages for creation, transcendence, sacred presence, revelation, and ultimate reality. Even within one tradition, philosophers, theologians, mystics, and ordinary believers may emphasize different attributes.
A careful comparison therefore asks what a tradition itself means by its terms rather than assuming that every religion is describing the same concept in different words.
Other monotheistic and philosophical approaches
The Bahá’í Faith teaches one God whose reality exceeds complete human comprehension and whose guidance is known through a succession of divine messengers. Deism, found in some modern philosophical and religious thought, speaks of a creator while often rejecting continuing revelation or miraculous intervention.
Atheist and agnostic positions approach the question differently. Atheism denies or lacks belief in gods, while agnosticism emphasizes uncertainty or the limits of knowledge. These are not religions in a single uniform sense, but they are important positions in modern discussion of God.
Personal language and philosophical language
Some traditions speak of God as personal, knowing, willing, and responsive. Others use language such as ground of being, absolute reality, or the source of existence. These descriptions can carry very different meanings, so comparison works best when each tradition’s own concepts are kept distinct.
