Religious beliefs  are beliefs that induce worship or worship-related activities — This feature is also defeated by the counterexamples of Brahmin Hinduism and Theravada Buddhism, neither of which practices worship. The same is true for the religious beliefs of some ancient Greeks such as Aristotle and later the Epicureans who thought the gods neither knew about nor cared about humans. They certainly felt no obligation to worship such apathetic beings.
Having excluded gods and worship from our definition, we are left with very few features that all religious beliefs could possibly share in common. As philosopher Roy Clouser asks, “What common element can be found in the biblical idea of God in Judaism, Christianity and Islam, in the Hindu idea of Brahman-Atman, in the idea of Dharmakaya in Mahayana Buddhism, and the idea of the Tao in Taoism?” The answer, he argues, is that every religious tradition considers something or other as divineand that all of them have a common denominator in the status of the divinity itself.
While many religions disagree on what is divine, they all agree on what it means to be divine . The divine is simply whatever is unconditionally, nondependently real; whatever is just there. By contrast, everything nondivine ultimately depends for existence (at least in part) on whatever is divine. This idea of nondependence or its equivalent is the shared feature in all religious beliefs.
Clouser uses this common element to formulate a precise definition: A belief is a religious belief provided that it is (1) a belief in something as divine or (2) a belief about how to stand in proper relation to the divine, where (3) something is believed to be divine provided it is held to be unconditionally nondependent.
