A. God is said to be “one” to oppose polytheism (1 Cor. 8:4-6).
1. All life is from God: natural (Acts 17:23; 1 Tim. 6:13); spiritual (Eph. 2:1); eternal (Col. 3:4).
C. God is said to be “true” to oppose false gods (Isa. 44:9-20; 1 Thess. 1:9).

C. There are two truths to safeguard when stating the doctrine of the Trinity.
1. The unity of God.
2. The plurality within the Godhead.
D. There are three essential elements in asserting the doctrine of the Trinity.
1. There is only one God (monotheism).
2. There are three persons that are each God (Trinitarianism).
3. The three persons are each distinct.
a. It has been said that all error somehow traces back to a defective view of God.
b. This doctrine is practical, under-girding the plan of salvation, and is not just some abstract truth.
II. Jesus Christ and the Holy Spirit are the greatest proof of the Trinity.
A. The deity of the Father is not usually questioned (Ga. 1:1).
B. The deity of Jesus is proven through four lines of evidence: Name, Attributes, Work, and Worship.
C. The deity of Christ: Name.
1. The name of God is applied to Christ by the OT passages that pertain to Jehovah, and that the NT applies to Jesus.
a. The “Lord of lords” (Deut. 10:17; cf. Rev. 19:11-16).

9:5; Phil. 2:5-11; Col. 1:15-17; 1 Tim. 3:16; Tit. 2:13; Heb. 1:8-9; cf. Ps. 45:6-7; Heb. 1:10-12;
cf. Ps. 102:25-27; 1 Jn. 5:20; Rev. 4:8;).
f. John said that Isaiah saw the glory of Jesus (Jn. 12:41; cf. Isa. 6:1-8).
3. The name of God Jesus claims for Himself in His many “I AM” statements (Ex. 3:14; Jn. 8:58; cf. 5:18).
a. “I am the Bread of Life” (Jn. 6:35, 48, 51).

III. The deity of the Holy Spirit: Name, Attributes, Work, Worship.
A. The Holy Spirit is explicitly called God (Acts 5:3-4).
1. Paul said that He who was speaking to Isaiah was the Holy Spirit (Acts 28:25-27; cf. Isa. 6:9-10).
a. The Holy Spirit is further equated with Yahweh (Jer. 31:31, 33-34; cf. Heb. 10:15).
B. The Holy Spirit possesses the attributes of God.
1. The Holy Spirit is: omniscient (1 Cor. 2:10-11); eternal (Heb. 9:14); omnipresent (Ps. 139:7-10); omnipotent (Rom. 15:19); sovereign (Jn. 3:8); the object of faith (Matt. 28:19).

D. The Holy Spirit is worshiped (Matt. 12:31; 28:19).
E. The Holy Spirit is a distinct person.

IV. Christ taught that God was triune and the disciples were firmly convinced Trinitarians.
A. The baptismal formula of Christ proves the Triune nature of God (Matt. 28:19).
1. Jesus said baptize them into the “name.”
a. The name is singular.
(1). To the Jewish mind the “name” would have been taken to be God (Lev. 24:11; Deut. 28:58; Isa. 59:19).
(2). The name of someone pertains to his nature (1 Sam. 25:25).
b. The name is not “of the Father, Son, and Holy Ghost” as if synonymous, but distinguishes each as having their own identity and personality.
(1). The Son and the Holy Spirit each take a definite article (“the”).
(2). The Father, Son, and Holy Spirit are each in the genitive case, showing possession of the one “name.”
B. The Trinitarian benediction (2 Cor. 13:14) shows that each person is distinct and equal in power and glory.
C. Each person being God and manifesting Himself as such caused the disciples to believe in the Trinity (Matt. 3:16-17; Eph. 2:18; 4:4-6; 2 Th. 2:13; 1 Pet. 1:2; Rev. 1:4-6).
D. Gregory of Nazianzus (c. 329-389 AD ) said: “I cannot think of the One, but I am immediately surrounded with the splendor of the Three; nor can I clearly discover the Three, but I am suddenly carried back to the One.”
V. Christ is not subordinate ontologically, but is subordinate in His role.
A. Christ said He could do nothing of Himself because He came to do His Father’s will (Jn. 5:19, 30; cf. 6:38).
B. Christ said that the Father was “greater” than Himself (Jn. 14:28).
1. In His role as servant, and as man (Phil. 2:7) the Father is greater.
a. Note Christ did not say “better,” which is a value judgment.
b. Note Christ had just told Phillip that if he had seen Him he had seen the Father (Jn. 14:9).
(1). Analogy: The President of the United States is greater than a citizen; the warden of a prison is greater than an inmate.
C. Some terms and passages referring to Christ are often twisted to deny His deity.
1. The term “only begotten” (Gk., monogenes) is used 5 times in the NT in reference to Christ (e.g., Jn. 1:14). The most authoritative grammars and lexicons all render it “only” or “unique,” the “only member of a kin or kind.”
a. Christ is the unique Son of God, who has the preeminence (Col. 1:15-18).
2. “Sonship” in the Western meaning means derivation, inferiority, subordination. The Bible uses sonship in the Semitic sense of a likeness of essence—a sameness.
a. Jesus is the express image of the Father (Heb. 1:3) just as we say a son is the “spitting image” of his father.
3. “Firstborn” (Gk., prototokos [e.g., Col. 1:15, 18]) also can be rendered “first begetter” or “original bringer forth.”
a. In Colossians this term is a comparison between Christ and created things. Christ is the “firstborn” from the dead, that is, the One with the preeminence, or right to rule over death (v. 18).
(1). Jesus, Creator of all things, clearly can’t be created Himself (v.16).
(2). In Romans “firstborn” is applied to Christ denoting His preeminence (8:29).
4. In Mark’s gospel Jesus said that even He did not know the time of His Second Coming (13:32).
a. This pertains to His human nature, which was not omniscient.
(1). Christ was fully man (Heb. 2:17-18).
VI. There is a unity between the Father, the Son, and the Holy Spirit.
A. The sheep are kept by both the Father and the Son because they are “one” (Jn. 10:28-30).
B. The Father is “in” the Son and the Son is “in” the Father (Jn. 14:9-11).
C. The Father and Son make their home with the believer through the indwelling of the Holy Spirit (Jn.
D. The Spirit of God is the Spirit of Christ (Rom. 8:9).
VII. The OT does not contain a full revelation of the Trinity, but does contain several indications.
A. The plural references to God (Gen. 1:26; 3:22; 11:7; Isa. 6:8).
B. The “threeness” found in Scripture (Gen. 1:1-3; cf. Ps. 33:6, 9; Jn. 1:1).
C. The mysterious trio (Gen. 18:1–19:24).
D. The Angel of the Lord identified as God, and yet distinct (Gen. 16:10, 13; 31:11-13).
1. The Angel as both Yahweh and distinct from Yahweh is a paradox solved in Christ who is also God and man. The Angel appearing at significant moments and taking a redemptive role to God’s people surely foreshadows Christ’s work. God initiating (Hagar [Gen. 16:7], Jacob [32:22-32], etc.), and drawing close to His people in the Angel (His “presence” [Ex. 32; 33; cf. 1 Cor. 10:1-10]).
E. The Spirit of God is present.
1. The Holy Spirit: creates (Job 26:13); gives wisdom for artisanship (Ex. 31:2-4); came upon David when anointed (1 Sam. 16:13); left Saul when he offended God (v.14); was grieved (Isa. 63:10); is spoken of as anointing the Messiah (Isa. 61:1); is the Spirit of grace and supplication (Zech. 12:10); indwells (Ps. 51:11).
a. The clear revelation of the personhood of the Spirit in the NT mandates that the OT portions must be similarly interpreted.
VIII. The full revelation of the Trinity was the inevitable outcome of redemption being accomplished.
A. The Son of God came to be a sacrifice (Incarnation).
B. The Spirit came to convict of sin, righteousness, and judgment (Pentecost).
C. The Father sends the Son, and the Father and the Son send the Spirit.
D. The Father elects, the Son atones for sin, and the Spirit applies redemption.
1. B.B. Warfield used a metaphor regarding the OT’s revelation of the Trinity: “[A] chamber richly furnished but dimly lighted; the introduction of light brings into it nothing which was not in it before; but it brings out into clearer view much of what is in it but was only dimly or even not at all perceived before. The mystery of the Trinity is not revealed in the OT; but the mystery of the Trinity underlies the OT revelation, and here and there almost comes into view. Thus the OT revelation is not corrected by the fuller revelation which follows it, but only perfected, extended and enlarged.”
A. Use, of knowledge.
1. This article of faith is essential to salvation. The mystery of the Trinity undergirds all of Christianity; without it there can be no true faith, right worship, or obedience.
B. Use, of testing.
1. Are we truly Trinitarians?
2. Do we esteem one person of the Trinity above the others?
C. Use, of exhortation: sinners and saints.
1. Sinners. Those who: are without God have no hope in the covenant (Eph. 2:12); deny the Son have not the Father (1 Jn. 2:23); have not the Spirit are not of Christ’s (Rom. 8:9).
2. Saints. Adore the Holy Trinity and though it is the highest mystery of our faith endeavor to be prepared to defend this hope which is in you.
