The Christian doctrine of the Trinity (Latin: Trinitas, lit. ' triad ', from trinus, "threefold '') holds that God is three consubstantial persons or hypostases -- the Father, the Son (Jesus Christ), and the Holy Spirit -- as "one God in three Divine Persons ''. The three persons are distinct, yet are one "substance, essence or nature '' (homoousios). In this context, a "nature '' is what one is, whereas a "person '' is who one is. The opposing view is referred to as Nontrinitarianism.
