Most utilized Unitarian (esp. JWs) Objections to the Trinity

Never was there a more deceptive doctrine advanced than that of the Trinity. It could have originated only in one mind, and that the mind of Satan the Devil (Reconciliation [Watchtower Bible and Tract Society, 1928], p. 101).

Since the beginning of human history, the nature of God (i.e., how He revealed Himself) has been furiously attacked (esp. ontological monotheism).[1] Though, one of the first heresies that emerged in first century church was that of the Judaizers.[2] And the second heresy that the early church dealt with was that of the Gnostics.[3] Both of which were thoroughly refuted by the apostles in there writings.[4]

Jesus was clear on the subject: eternal life is to have “knowledge” of the true God (cf. John 17:3; 8:24; 1 John 5:20). And Scripture presents that there is one true God who revealed Himself in three coequal, coeternal, and coexistent *distinct* persons—thus, God is Triune. The biblical data is undeniable. But many today (and historically) deny, in some way, shape, or form, the doctrine of the Trinity. We are not speaking of some peripheral, non-essential doctrine here: The belief in the doctrine of the Trinity is essential to ones salvation, for it is how God revealed Himself—the very nature or essence of His essential Being, the only true God.

If one removes the Son from the Trinity (in any way), the Son is reduced to either to a created being (as with, for example, Oneness believers and Jehovah’s Witnesses [JWs]) or the Son becomes a “separate” God (as in Mormonism). The Trinity is the biblical explanation of how there is one God and yet the Son is presented as both Creator[5] and “God” (theos)[6] distinct from the Father and Holy Spirit who are likewise presented as God.[7]

Main Objections to the Trinity 

1) The term “Trinity” is not found in the Bible.

2) The Trinity teaches three Gods.

3) The Trinity was invented in the fourth century (viz. at the Council of Nicaea, A.D. 325) and thus, it is not taught in the Bible.

First objection. This argument is nonsensical for many reasons. It is true that the exact word “Trinity” does not appear in the Bible. If the individuals using this argument were consistent, then, they would not believe that God is “1 person” either, because the word “unitarian” does not appear in the Bible. In point of fact, Christians today (as well as the early Christian church, as noted above) use the doctrinal term Trinity to describe God because it simply adequately denotes the teaching and concept of a triune multi-personal God presented throughout Scripture. Consider that the terms: incarnation, coequal, coeternal (with the Father), and the phrases: hypostatic union, God the Son, substitutionary atonement, etc., which are all true of Christ, do not appear in the Bible. Also, the terms omnipresent, omniscient, omnipotent, self-existent, etc., which are all ascribed to God, do not appear in the Bible; however, the teachings or concepts of these doctrinal words and phrases do. They are clearly expressed in the biblical content.

Here are some of the doctrinal (nonbiblical) words mentioned above with their corresponding biblical passages expressing the teachings and concepts of these words:

Incarnation. This defines the teaching of God the Son becoming flesh – John 1:14 et al. God the Son (Mark 14:61-64; John 1:1, 18; Heb. 1:8, 10; 1 John 5:20 et al.). Hypostatic union of Jesus Christ. This describes the two natures of Christ, God and man (John 1:14; 1 Cor. 2:8; Phil. 2:6-7-8; 2 Tim. 2:8). The Son’s coequality and coeternality with the Father (Gen. 19:24; John 1:1c; 5:17-18; 10:30-33; 17:5; Heb. 1:3, 6, 8-12; Jude 1:4; Rev. 1:8, 5:13-14; 22:13).

Substitutionary atonement. This describes Jesus’ atoning cross work as a literal substitution for and on behalf of the elect (John 6:37-39; 10:17; Mark 10:45; Rom. 8:32; Gal. 1:4; Eph. 5:25; 1 Tim. 2:6).

Omnipresent. An attribute ascribed to God (Ps. 139:6-10; John 14:23 et al.).Although there are many more doctrinal words that can be mentioned that are not contained in the Bible, they all do indeed express the biblical teachings and concepts they represent.

Second objection (The Trinity = 3 separate Gods.): To say that the Trinity teaches three Gods is a gross misrepresentation of the doctrine. As noted, the very foundation of the Trinity is monotheism—namely, the Bible teaches that there is only one true God.
 
Three Gods/gods is not biblical trinitarianism rather, it is polytheism (many true Gods/gods. Or henotheism (hen, “one” Theos, “god”), which is the belief that although many true Gods/gods exist, worship and devotion is to only one God. Hinduism and the LDS Church, that is, Mormonism hold to this view. Mormons acknowledge the existence of many true Gods of other planets, but they only worship and the God for this planet. See our article: Are Mormons Christians? Contra to the many “true” Gods of Mormonism, both the OT and NT condemns that (Exod. 20:5; Isa. 43:10; 45:5; Mark 12:28-29; 1 Tim. 2:5 et al.). As shown above, the Bible teaches that there are three distinct persons who share the nature of the one true God. Or, there is one true God (one Being) who is revealed in three coequal coeternal coexistent distinct persons—the Father, and the Son, and the Holy Spirit. As delineated above, the three biblical propositions or truths affirm the Trinity.

1. There is one true eternal God (viz., one Being).

2. There are three persons referred to as God, YHWH, and the Creator of all things— the Father, and the Son, and the Holy Spirit.

3. These three persons are distinct from each other.

Third objection (The Trinity wasn’t invented until the Council of Nicaea, A.D. 325). First, the issue at the Council of Nicaea was not the Trinity, that had already been established in the early church decades before Nicaea. In point of fact, there are no primary source documents that came out of Nicaea that even mention the term “Trinity” or specifically discuss it. Instead, the Council primarily addressed the heretical teachings of Arius who openly taught that the Son was created, “a god,” but not “Almighty God,” similar to what the JWs teach. Arius taught that Jesus was of a “different substance” than that of the Father in direct opposition to the orthodox position, which taught that Jesus was of the “same substance” (homoousios, viz. coequal, consubstantial) as that of the Father, but not the same person. So, the chief issue at Nicaea was the question of the ontological relationship between the Father and the Son—not the Trinity per se

NOTES

[1] Ontological (by nature) monotheism (one God) is the doctrine that there exists only one God by nature (cf. Deut. 4:35; Jer. 10:10-11). Mormons, although, claim that the Father, Son, and Holy Ghost are “one God,” but only in the sense of “unity,” not one in essence. But, as they assert, these three are three “separate” Gods, with the Father as the head God in whom they worshiped alone—thus, the Mormon view of the Godhead. But whether one or more Gods are worshiped is irreverent, the question is: how many true Gods exist? The fact that the Mormons believe that many “true” Gods exist, therefore, categorizes the Mormon people as overt polytheists (the belief in many true Gods) and hence, non-Christian. Not only in the OT, but in the NT as well, strict monotheism was strongly asserted (e.g., Mark 28:29; John 17:3; 1 Tim. 2:5).

[2] Simply, the Judaizers taught that one had to practice the OT law, rituals, ordinances, etc. (esp. circumcision), to obtain salvation. And this, was the primary reason as to why Paul wrote to the Galatians.

[3] The Gnostics (from gnōsis, meaning “knowledge”) held to a dualistic system: spirit was good and all “matter” (esp. flesh) was inherently evil; some even taught that “matter” did not exist; it was illusory—as with the theology of Christian Science today. Both the Apostle John and Paul specifically refuted this teaching (esp. in Col. and 1 & 2 John).

[4] As seen above.

[5] E.g., Isa. 9:6; John 1:3; Col. 1:16-17)

[6] E.g., John 1:1, 18; Titus 2:13; Heb. 1:3, 8-10

[7] Of course, the OT and NT teaching of “one God” (i.e., monotheism) does indicate or equate “one person” as *unitarian* groups such as Jews, Muslims, JWs, Oneness Pentecostals, etc. presuppose. Monotheism simply means “one God” (viz. “one Being”). To argue that “one God” equals “one person” is to argue in a circle. It assumes what is meant to be proven.
