The three great monotheistic religions of the world are Judaism, Christianity, and Islam. All three claim to worship the one and only God, the God of the Bible. But all three disagree as to who this God is.
Most Christians are Trinitarians because they believe in their doctrine of the Trinity. (I was a Trinitarian for 22 years.) Their theologians explain that it means God is one essence subsisting in three co-equal and co-eternal Persons: the Father, the Son (Jesus Christ), and the Holy Spirit.
Both Jews and Muslims disagree with this doctrine of the Trinity. They allege that it seems like tritheism—the worship of three gods. Christians vehemently deny this; yet they contend that the Father is God, Jesus Christ is God, and the Holy Spirit is God, and they distinguish them as three separate Persons. To most unbiased souls, that presents simple arithmetic: these three Persons in a Godhead tallies up to be three Gods, thus agreeing with Jews and Muslims. Trinitarians reply by asserting that their doctrine is mysterious, inscrutable, and incomprehensible. If that is true, then the three Catholic theologians from Cappadocia who formulated this doctrine of the Trinity during the 370s, in their extensive treatises, must not have understood it either!
Most Trinitarians also presume that these “three members of the Trinity,” as they call them, are in heaven and that they are worshipped there by an innumerable company of angels. But this presumption cannot be verified in the New Testament (NT) regarding the Holy Spirit.
The NT declares that Jesus was crucified, died, raised from the dead, and that he ascended into heaven and sat down with God the Father on his throne at his right hand. So, a prominent image Christians have always had is of Jesus sitting alongside God the Father on the Father’s throne in heaven, with angels surrounding them with song and praise.
No Bible book or letter contains as much information about heaven as does the book of Revelation. Its most prominent theme is the sovereignty of “the God of heaven” (Rev 11.13; 16.11). Jesus constantly called him “the/my Father” and described him as “my Father who is in heaven.” He once addressed him as his “Father, Lord of heaven and earth” (Luke 10.21).
The primary image conveyed in the book of Revelation is of God enthroned in heaven. Thus, God’s heavenly throne serves as a symbol of his sovereign authority in heaven, in our universe, and thus on earth. God is depicted six times in this apocalyptic book as “he/him who sits on the throne.” A multitude of angels cry out with a loud voice, “Salvation to our God who sits on the throne, and to the Lamb” (Rev 7.10). The Lamb is a title for Jesus Christ. He is portrayed as sitting there alongside of God the Father on the Father’s throne. And the angels in heaven “worshiped God who sits on the throne” (Rev 19.4).
In the book of Revelation, God clearly and repeatedly is distinguished from the Lamb, Jesus Christ. This distinction always indicates that only the Father is God, so that Jesus Christ cannot also be God. Revelation quotes the heavenly Jesus calling the Father “My God” five times (Revelation 3.2, 12), and it tells of “his God and Father” (1.6), restricting the word “God” to the Father.
Jesus calling the Father “my God” is strong evidence that Jesus is not God. If so, and all three members of the Trinity are co-equal, it would seem that Jesus is the God of the Father, etc. But the Bible never says that. Instead, on the cross Jesus cried out, “My God, my God, why have you forsaken me?” (Matthew 27.46), a quotation from Psalm 22.1. And the risen Jesus told Mary Magdalene, “Go to my brothers [apostles] and say to them, ‘I am ascending to my Father, and your Father, to my God, and your God'” (John 20.17).
The Apostle Paul repeatedly writes likewise, “the God (and Father) of our Lord Jesus Christ” (2 C0rinthians 1.3; Ephesians 1.3, 17; cf. Colossians 1.3).
Furthermore, ten times the book of Revelation quotes heaven’s citizens, who are surely angels, as calling the Father “our God” (Revelation 4.11; 5.10; 7.3, 10, 12; 12.10; 19.1, 5-6). Sometimes, it does so when both God the Father and Jesus Christ are mentioned together. For example, a loud voice in heaven spoke about “the kingdom of our God and the authority of His Christ” (12.10). Thus, only the Father is the God of heaven’s citizens.
So, the book of Revelation reveals that Jesus Christ does not have his own throne in heaven, that is, one that is separate from the Father’s throne. There is only one throne that God the Father and Jesus Christ sit on in heaven, and they share it together. But it is the Father’s throne.
Trinitarians insist that the Holy Spirit, which most call “the third Person/member of the Trinity,” is a full-fledged Person just as God the Father and Jesus Christ are Persons. Yet, of all of the heavenly scenes in the book of Revelation that portray a multitude of angels, twenty-four elders, and four living creatures all praising God the Father and Jesus Christ, there is no mention of the Holy Spirit even existing in heaven let alone sitting on a throne or being worshipped there. (In all of the heavenly scenes described in the book of Revelation, which are in Revelation 4-19, the Holy Spirit is only mentioned once, in Revelation 14.13.)
Why isn’t the Holy Spirit mentioned in the book of Revelation in any of it heavenly scenes which portray God and Jesus? It is because the Holy Spirit is not a person. Rather, the Holy Spirit (=the Spirit of God) is to God what man’s spirit is to man because man was made in the image of God. If the Trinity was correct, man would have to consist of three persons. Instead, Jews and Muslims are right, that God is a single individual, one person, whom Jesus constantly called “my/the Father.”
That blessed act of Jesus’ heavenly exaltation—in which God the Father invited Jesus to sit with him on his throne—does not necessarily suggest that Jesus is essentially equal with the Father and thus possesses deity. Rather, this exaltation both magnifies Jesus’ dependence upon God and manifests his subordination to God. Otherwise, if Jesus is God, co-equal with the Father in essence, we would expect Jesus to have his own throne in heaven, perhaps alongside of the Father’s throne and at the same height. The Father’s throne is the highest of all other thrones in heaven. That is why he is often described in the Bible as “the Most High” (e.g., Daniel 7.9, 25; Luke 1.32, 35). God’s throne belonging only to him, and it being high and lifted up (Isaiah 6.1; cf. 52.13), symbolizes his exalted rank, thus his superior dignity, over all, including over Jesus Christ (John 10.29; 14.28; 1 Corinthians 11.3).
The existence of one throne in heaven for God, with Christ at his side on that throne, affirms strict monotheism, thus nullifying Binitarianism and Trinitarianism. Trinitarian Richard Bauckham at least acknowledges, “In Second Temple Judaism, then, the throne of God in the highest heaven became a key symbol of monotheism.” And Marinus de Jong insists that “God on his heavenly throne remains the center of all worship (Rev 7:11-17), and adoration of the Lamb in no way endangers or diminishes the worship due him.”
To conclude, the most formidable image which refutes the notion of the Trinity is God the Father literally sitting on his heavenly throne with Jesus sitting alongside him. If the Trinity was true, and it is not, one would expect all three of its members to either sit together on one throne or have their own thrones in heaven. Either way, no manner of mental gymnastics could escape the allegation that such an image presents three Gods. Yet the Bible repeatedly states the concept that there is only one true and living God.
