holy trinity

Christian doctrine that God is one God, but three coeternal consubstantial persons

The Christian doctrine of the Trinity holds that God is one God, but three coeternal and consubstantial persons: the Father, the Son, and the Holy Spirit. 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.
