TRINITY, THE HOLY
A term used since A.D. 200 to denote the central doctrine of the Christian religion. God, who is one and unique in his infinite substance or nature, is three really distinct persons, the Father, Son, and Holy Spirit. The one and only God is the Father, the Son, and the Holy Spirit. Yet God the Father is not God the Son, by generates the Son eternally, as the Son is eternally begotten. The Holy Spirit is neither the Father nor the Son, but a distinct person having the divine nature from the Father and the Son by eternal procession. The three divine persons are co-equal, co-eternal, and consubstantial and deserve co-equal glory and adoration.
