Apologetics for the Doctrine of the Trinity, Part 3

1. The Trinity is not beyond our ability to understand and it is not confusing.

2. The Council of Nicea (A.D. 325) and the Council of Constantinople (A.D. 381), which asserted the deity of Christ and the Holy Spirit were convened to refute Arianism (A.D. 319).

3. The word ‘Trinity’ became a technical word for the three persons of the Godhead after the success of these councils.

4. The Trinity is taught in the O.T. (GEN 1:1; GEN 1:26-27; GEN 3:22; DEU 6:4)

5. The Trinity is taught in the N.T. where it is revealed that God is one (1TI 2:5), God the Father is God (1CO 8:6), Jesus Christ is God (JOH 1:1; ROM 9:5; TIT 2:13; 2PE 1:1), and the Holy Spirit is a person and is God (…).

“If Christ was in the form of God, equal with God, and very God, it was then an act of infinite love and condescension in him to become a man; but if he was no more than a creature, it was no surprising condescension to embark in a work so glorious; such as being the Savior of mankind, and such as would advance him to be Lord and Judge of the world, to be admired, reverenced, and adored, both by men and angels.”

4. God the Holy Spirit is a Person and is God.

a. The Holy Spirit is a person:

JOB 33:4
The Spirit of God has made me,
And the breath of the Almighty gives me life.

b. The Holy Spirit speaks.

MAT 10:20
For it is not you who speak, but it is the Spirit of your Father who speaks in you.

ACT 8:29
And the Spirit said to Philip, “Go up and join this chariot.”

ACT 10:19
And while Peter was reflecting on the vision, the Spirit said to him, “Behold, three men are looking for you.”

ACT 11:12
And the Spirit told me to go with them without misgivings. And these six brethren also went with me, and we entered the man’s house.

ACT 13:2
And while they were ministering to the Lord and fasting, the Holy Spirit said, “Set apart for Me Barnabas and Saul for the work to which I have called them.”

ACT 28:25
And when they did not agree with one another, they began leaving after Paul had spoken one parting word, “The Holy Spirit rightly spoke through Isaiah the prophet to your fathers

c. The third person masculine singular personal pronoun is used to describe God the Holy Spirit.

“He” here in verse 14 refers to the Spirit of truth mentioned in verse 13 – the Holy Spirit.

The word for “spirit” is pneuma.

The Greek noun pneuma was given the gender of neuter.

The first word in verse 14 in the Greek is the Greek pronoun ekeinos and it refers back to the Spirit of truth in verse 13 – it refers back to pneuma.

Nominative signifies that it is the subject of the sentence.
Singular makes it clear that ekeinos refers to the Spirit of truth, rather than any other noun in the previous sentence.

The neuter form of this pronoun in the nominative singular would be ekeino.
We have ekeinos. This is the MASCULINE form of this pronoun.

He used this opportunity to clarify for all future readers of this Gospel that the noun pneuma does not refer to an “it”. Pneuma is a He, the Third Person of the Trinity!

d. God the Holy Spirit is God:

Who spoke through Isaiah? Adonai who is Jehovah.

Adonai asks, “who will go for Us?” We have the plural use in the prepositional phrase for the Trinity.

Isaiah spoke these things because He saw His glory and he spoke of Him.

Isaiah saw the glory of Jehovah, which is Jesus Christ according to John 12:41.

The three uses of “Holy” refers to the three members of the Trinity. Interestingly Jehovah is used in verse three instead of Elohim to emphasize that they are one.

e. It is God the Holy Spirit that gives life.

1 Tim 6:13
I charge you in the presence of God, who gives life to all things

The Holy Spirit Sovereignly distributes spiritual gifts.

The Holy Spirit is eternal.

John 6:63 It is the Spirit who gives life; the flesh profits nothing; the words that I have spoken to you are spirit and are life. 1CO 12:11
But one and the same Spirit works all these things, distributing to each one individually just as He wills. HEB 9:14
how much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God?

“eternal” is the Greek adjective aionios which means eternal.

Kittel’s Theological Dictionary of the NT:
As a predicate of God aionios contains not merely the concept of unlimited time without beginning or end, but also of the eternity which transcends time.
