W.H. Griffith Thomas (A.D. 1861 - 1924)
"The threefold distinction in God, which is expressed by the word "Trinity," is an attempt of man to conceive and express the meaning of the Infinite God in terms of Jesus Christ, and we believe that the use of the phrase, "The Father, the Son, and the Holy Spirit," is the very best rendering of the mystery that can be given .... The true meaning of Trinitarian doctrine, therefore, is not separate spheres of Divine operation in connection with each Person, but the united and inclusive operations of three Persons in one God .... When we turn to St. Paul, we find substantially the same set of ideas. The language about the indwelling of Christ and of the Spirit is practically identical ....We are therefore not at all surprised at the variation of the theological expression connected with the Holy Spirit. Sometimes He is regarded as a separate Personality within the Godhead, having self-consciousness separate from and yet connected wth Jesus and the Father. At other times the Spirit is used for the Name of God's own personal activity, as He dwells in the soul of man. But however difficult it may be to express the difference between Christ and the Spirit regarded as within God Himself, no difficulty must allow us to ignore the plain teaching of the New Testament and the personal testimony of Christian consciousness. In our Lord's discourse, while He distinquishes between the relations of the Father and the Spirit with Himself to the disciples, yet there is no essential dfference or separation. Whether the Father lives or the Son lives; whether the Father comes or the Son comes; whether the Father gives the Spirit or the Son gives Him, the essential relationship is the same. But while closely and intimately connected, Christ and the Spirit are never identical ... It is essential to preserve with care both sides of this truth. Christ and the Spirit are different yet the same, the same yet diffeent. Perhaps the best expression we can give is that while their Personalities are never identical, their presence always is."
