Homoousian

Homoousian (/ˌhɒmoʊˈuːsiən/ HOM-oh-OO-see-ən; Ancient Greek: ὁμοούσιος, from the Ancient Greek: ὁμός, homós, "same" and Ancient Greek: οὐσία, ousía, "being") is a technical theological term used in discussion of the Christian understanding of God as Trinity. The Nicene Creed describes Jesus as being homooúsios with God the Father — that is, they are equally God. This term, adopted by the First Council of Nicaea, was intended to add clarity to the relationship between Christ and God the Father within the Godhead. The term is rendered "consubstantialis" in Latin and in related terms in other Latin-derived languages which lack a present participle of the verb *to be*. It is one of the cornerstones of theology in Christian churches which adhere to the Nicene Creed.
