We believe that God is Spirit (John 4:24; 2 Corinthians 3:17), and He is alive by His Spirit. The Holy Spirit is the Spirit of God; and He is the Person (i.e. Hypostasis) representing life in the Holy Trinity; therefore, there was no time when there was no Holy Spirit. The Spirit of God is the Spirit of the Father and the Spirit of the Son; always existing with the Father and the Son; perpetually worshipped and glorified with them in the oneness of the Holy Trinity. Therefore He is divine, holy, eternal, and uncreated. The Lord Jesus called Him “The Holy Spirit” as in His saying to His disciples, “Receive the Holy Spirit…” (John 20:22); and about commencing their ministry, He said, “But you shall receive power when the Holy Spirit has come upon you...” (Acts 1:8). St. Paul also called Him “The Holy Spirit” during his speech to the bishops of Ephesus, “Take heed to yourselves and to all the flock, among which the Holy Spirit has made you overseers…” (Acts 20:28). To the Jews in Rome, he said, “The Holy Spirit spoke rightly through Isaiah the Prophet to our fathers…” (Acts 28:25). You may also find verses mentioning the Holy Spirit by the word “The Spirit” (Revelation 2:29; 3:6, 13, 22; John 3:5; Acts 2:4; 1 Corinthians 12).
The Holy Spirit is the Spirit of the Lord God:
“The Spirit of the Lord God is upon Me, because the Lord has anointed Me…” (Isaiah 61:1).
“Now the Lord is the Spirit; and where the Spirit of the Lord is, there is liberty” (2 Corinthians 3:17).
“Do not take Your Holy Spirit from me” (Psalms 51:11).
The Holy Spirit is the Spirit of the Father (cf. Joel 2:28; Ezekiel 36:27; Psalms 139:7).
“For it is not you who speak, but the Spirit of your Father who speaks in you” (Matthew 10:20).
“God has sent forth the Spirit of His Son into your hearts” (Galatians 4:6).
“Searching what, or what manner of time, the Spirit of Christ who was in them was indicating when He testified beforehand the sufferings of Christ” (1 Pet 1:11).
The fact that the Holy Spirit is the Spirit of the Father and the Spirit of the Son, undoubtedly demonstrates the unity of the Holy Trinity.
Godhead of the Holy Spirit
The Lord Christ Himself asserted the Godhead of the Holy Spirit by saying, “God is Spirit, and those who worship Him must worship in spirit and truth” (John 4:24). God is Spirit, He is then the Holy Spirit, and both the Father and the Son (in His divinity) is Spirit as well. This fact is evident in the writings of the apostles:
St. Paul says, “The Lord is the Spirit” (2 Corinthians 3:17).
St. Peter reprimanding Ananias saying, “Why has Satan filled your heart to lie to the Holy Spirit… You have not lied men but to God” (Acts 5:3, 4).
St. Paul wrote that the Holy Spirit dwells within us, “Do you not know that your body is the temple of the Holy Spirit who is in you… Do you not know that you are the temple of God and that the Spirit of God dwells in you?” (1 Corinthians 6:19; 3:16).
The Divine Attributes of the Holy Spirit
The following attributes are of God alone; and attributing them to the Holy Spirit proves His divinity:
The Holy Spirit has the power to create: In the story of creation, the Holy Spirit of God was hovering over the face of the waters (Genesis 1:2). It is the same Spirit, who is the “breath of life” for man, made in the image and likeness of God (Genesis 1:30; 2:7). Generally speaking, the Spirit in Hebrew is called “breath” or the “wind” of Yahweh. The Psalmist says, “These all wait for You, that You may give them their food in due season… You take away their breath, they die and return to their dust. You send forth Your Spirit, they are created” (Psalms 104:27-30).
The Holy Spirit is omnipresent: The Psalmist says, “Where can I go from Your Spirit? Or where can I flee from Your presence? If I ascend to heaven, You are there; if I make my bed in hell, behold, You are there” (Psalms 139:7, 8).
The Holy Spirit gives His gifts to people: St. Paul says, “There are diversities of gifts, but the same Spirit… and there are diversities of activities, but it is the same God who works all in all. But the manifestation of the Spirit is given to each one for the profit of all: for to one is given the word of wisdom through the Spirit, to another the word of knowledge through the same Spirit, to another the working of miracles, to another prophecy… but one and the same spirit works all these things, distributing to each one individually as He wills” (1 Cor. 12: 4-11). All these are called by the apostle “gifts of the Holy Spirit” (Heb. 2:4). Of these gifts St. James the apostle said, “Every good gift and every perfect gift is from above, and comes down from the Father of lights; with whom there is no variation or shadow of turning” (James 1:17). Therefore all gifts are sent by God through His Holy Spirit.
The Holy Spirit is eternal: The Holy Spirit, being the Spirit of Christ, is eternal, as St. Paul says, “… How much more shall the blood of Christ, who through the eternal Spirit offered Himself without spot to God…” (Hebrew 9:14). It is proof of the divinity of Christ and of the Holy Spirit.
The Holy Spirit is the life-giver: The Holy Spirit is the giver of life. Ezekiel the Prophet said, “The hand of the Lord came upon me and brought me out in the Spirit of the Lord, and set me down in the midst of the valley; and it was full of bones… and He said to me, ‘Son of man, can these bones live?’ So I answered, ‘O Lord God, You know’… and breath came into them, and they lived.” (Ezekiel 37:1-3, 10). And the Lord said, “I will put My Spirit in you, and you shall live” (Ezekiel 37:14). No doubt it is God who gives life to the dead through His Holy Spirit. He puts His Spirit in them and they live. The Book of Revelation likewise says about the two witnesses who were killed, “The breath of life from God entered them, and they stood on their feet” (Revelation 11:11). The Lord Christ says, “It is the Spirit who gives life” (John 6:63).
The Holy Spirit is the Spirit of Truth: “When He, the Spirit of truth has come, He will guide you into all truth; for He will not speak on His own authority, but whatever He hears He will speak, and He will tell you the things to come” (John 16:13; c.f. John 14:25; John 15:26).
