I will put my spirit within you…and ye shall keep my judgments, and do them. —Ezekiel 36:27
How shall we think of the Holy Spirit? The Bible declares that He is God. Every quality belonging to Almighty God is freely attributed to Him. All that God is, the Spirit is declared to be. The Spirit of God is one with and equal to God just as the spirit of a man is equal to and one with the man….
The historic Church when she formulated her “rule of faith” boldly wrote into her confession her belief in the Godhood of the Holy Ghost. The Apostles’ Creed witnesses to faith in the Father and in the Son and in the Holy Ghost and makes no difference between the three. The fathers who composed the Nicene Creed testified in a passage of great beauty to their faith in the deity of the Spirit:
And I believe in the Holy Ghost, the Lord and Giver of life, who proceedeth from the Father and the Son; who with the Father and the Son together is worshiped and glorified. POM066-067
[A]ll that the Son is the Holy Ghost is, and all that the Father is the Holy Ghost is, and the Holy Ghost is in His Church. HTB020
