Chapter 2 – God and the Holy Trinity

2nd – ASSERTIONS OF THE DEITY OF JESUS CHRIST AND THE HOLY SPIRIT

B.B. Warfield, Works (vol.2, p.146) - ‘...that Jesus Christ is God manifested in the flesh, and that the Holy Spirit is a divine Person, is just so much evidence for the doctrine of the Trinity; and that when we go to the New Testament for evidence of the Trinity we are to seek it, not merely in the scattered allusions to the Trinity as such, numerous and instructive as they are, but primarily in the whole mass of evidence which the New Testament provides of the Deity of Christ and the Divine personality of the Holy Spirit.'

In other words, if we believe that the Scriptures teach that there is only one, true and living God; and if we find that the Scriptures also teach that the incommunicable attributes, names, and the worship of God, belong to Jesus and the Holy Spirit; then we must conclude that there is one God revealed to us in three persons.
