A triad, in a religious context, refers to a grouping of three gods, usually by importance or similar roles. A triad of gods were usually not considered to be one in the same being, or different aspects of a single deity as in a Trinity or Triple deity. Triads of three closely associated deities were commonly found throughout the ancient world, and in particular in the religious traditions of Ancient Greece and Egypt.

Christian Trinity

The Christian doctrine of the Trinity (, from "threefold") defines God as being one god existing in three coequal, coeternal, consubstantial persons: God the Father, God the Son (Jesus Christ) and God the Holy Spirit — three distinct persons sharing one essence. In this context, the three persons define God is, while the one essence defines God is. This doctrine is called Trinitarianism and its adherents are called trinitarians, while its opponents are called antitrinitarians or nontrinitarians. Nontrinitarian positions include Unitarianism, Binitarianism and Modalism.
