Patterns of belief focused on one or more god of extrahuman origin is called a theism. The pattern may be a reflection of social organization, e.g., the more centralized and stratified the society, the fewer gods.
- Monotheism: belief in one god (Judaism, Christianity, Islam)
- Henotheism: worship of only one god, while acknowledging that other gods exist. Henotheists do not necessarily view other gods as legitimate objects of worship, even while acknowledging they exist (Hinduism)
- Polytheism: belief in many gods (Aztec, ancient Greeks, Egyptians)
