- Latin: trini, three each, or threefold
The term used as early as the days of Tertullian (c. 200) to denote the central doctrine of the Christian religion. God, who is one and unique in Ilis infinite substance or nature, or Godhead, is three really distinct Persons, the Father, the Son, and the Holy Ghost. Each of these Persons is truly the sanle God, and has all His infinite perfections, yet He is really distinct fronl each of the other Persons. The one and only God is the Father, the Son, and the Holy Ghost; yet God the Father is not God the Son, but begets the Son eternally, as the Son is eternally begotten. The Holy Ghost is neither the Father nor the Son, but a distinct Person having His Divine nature from the Father and the Son by eternal procession. To illustrate this inscrutable mystery of God’s inner life (made known by Christ and Christian Revelation, and defined by the Church of Christ) the Father engenders the Son as His spiritual image, or Word, conceived by His infinite and eternal thought, while the Holy Ghost issues forth eternally as the personal term of the infinite act of mutual love of the Father and the Son. Thus the unique and indivisible Godhead subsists in three Persons, Who are constituted by distinct internal Divine relations. These Persons are co-equal, co-eternal, and consubstantial, and deserve co-equal glory and adoration, which the Church expresses in the often repeated prayer: “Glory be to the Father, and to the Son, and to the Holy Ghost.
