What Is The Trinity?

The Trinity

The Trinity can be defined as God eternally and necessarily existing as three persons, Father, Son, and Holy Spirit, and each person is fully God, and there is one God (Deuteronomy 6:4-5).

  • The Trinity is partially revealed in the OT (Psalms 45:6-7).
  • There are three distinct persons in the Trinity, and the being of each person is equal to the whole being of God (John 1:1-2).
  • There are no differences in deity, attributes, or essential nature between Father, Son, and Holy Spirit. The only distinctions between the members if the Trinity are in the ways they have and will always relate to each other and in the ways they relate to creation (1 Corinthians 15:28).
  • The doctrine of the Trinity denies both Tritheism (belief in three Gods) and Modalism (belief in only one person of God who appears in different forms).
  • Arianism and Subordinationism denied the full deity of the Son and the Holy Spirit.  Through the leadership of Athanasius, both of these were condemned as heresy at the Council of Nicea in AD 325, where it was affirmed that Christ is of the same nature as the Father.
  • If God were not triune, the atonement, justification by faith, worship of Christ, God as the source of salvation, the independent and personal nature of God, and the basis of the unity of the universe would all be lost.
  • Eternal equality is being but subordination in role has been essential to the church’s doctrine of the Trinity.
