Knowra Nontrinitarianism Nontrinitarianism Nontrinitarianism is the belief that rejects the Christian doctrine of the Trinity, holding that God is not three coequal, coeternal persons in one being.
Trinity : The Christian doctrine that God is one being in three coequal, coeternal persons: Father, Son, and Holy Spirit. This is the doctrine nontrinitarianism rejects.
Modalism : The view that Father, Son, and Holy Spirit are modes or manifestations of one divine person, rather than distinct persons. It rejects the Trinity’s three-person distinction but differs from many nontrinitarian accounts.
First Council of Nicaea : The 325 council that addressed the Arian controversy and affirmed the Son as of the same substance as the Father. Its creed made the Son’s coeternity and full divinity defining disputes.
Jehovah's Witnesses : A Christian restorationist movement that identifies Jehovah as the Almighty God and regards Jesus as his created Son. Its teachings reject the Trinity and distinguish Jesus from Almighty God.
Nicene Creed : A Christian creed affirming the Son’s full divinity and defining the relationship of Father, Son, and Holy Spirit. Its formulations established the creed nontrinitarian Christians do not affirm.
Unitarianism : A Christian theological tradition that understands God as one person and denies the coequal divinity of Jesus. It is a major nontrinitarian tradition, though the term also names broader religious movements.
First Council of Constantinople : The 381 council that reaffirmed Nicene teaching and articulated the divinity of the Holy Spirit. Its expanded creed addressed a doctrine nontrinitarian groups reject or reinterpret.
Christadelphians : A nontrinitarian Christian movement founded in the nineteenth century that emphasizes biblical authority and the coming Kingdom of God. Its theology denies the personal preexistence and coequality of Jesus.
Homoousion : A theological term meaning “of the same substance,” used at Nicaea to describe the Son’s relation to the Father. Its use in the Nicene Creed became a central point of nontrinitarian dispute.
Binitarianism : A theological view that understands divinity in terms of two persons, commonly the Father and the Son. It differs from nontrinitarian views that affirm only one divine person.
