Introduction
At the centre of the Christian faith stands one figure—Jesus Christ. The entire Christian experience—salvation, doctrines, practices, worship, and hope—revolves around His identity and work. Scripture describes Christ as the author and finisher of the faith of everyone who believes in Him (Hebrews
Yet, disputes persist regarding Jesus’ eternality and deity. Is Jesus a created being, the first and highest of God’s creations, created before the other creations? Was He just a man whom God chose and placed His power upon? Or is He the eternal Son of God who has eternally existed with the Father and shares the same essence with the Father?
The Bible’s witness about Christ is unambiguous: He was with God in the beginning, He is God, He is before all things, and all things were created through Him and for Him (John 1:1–3; Colossians 1:16–17). The Bible provides more than enough evidence for the eternality and divine identity of the Son.
Grasping Christ’s Sonship requires distinguishing His eternal existence from His incarnation, as well as His personal distinction from the Father. In this study, we will examine the Bible’s witness for the eternality and deity of the Son, address key objections to His divine identity, and consider the theological significance of these truths for knowing the Father and understanding salvation, faith in Christ, and Christian worship.
Understanding the Eternal Sonship of Christ
One of the titles by which Jesus is described in the New Testament is Son of God. This describes His unique relationship with the Father and His deity. It does not mean that God physically fathered Him or that He is a created being. It means, rather, that Christ is personally distinct from the Father, and possesses the divine nature.
The Father and the Son are distinct persons, not different titles for one person. Their personal distinction is evident throughout the New Testament. For example, in Matthew 3:16–17, as the Son was being baptized, the Spirit descended upon Him, and the Father spoke from heaven.
Yet this distinction does not apply to their nature. Jesus declares that He and the Father are one in essence (John 10:30). Thus, the Son is personally distinct from the Father, yet fully shares in the divine nature. This is the central thesis of the Bible’s doctrine of God: One Substance, Three Persons.
Jesus’ opponents understood His claim to being the Son of God as a claim to equality with God. Hence, the attempts to stone Him (John 5:18; John 10:31–33). But, rather than shrinking back, Jesus intensified His claim to a unique relationship with the Father and the divine honor due to Him (John 5:19–23).
Being the eternal Son of God means that Jesus’ existence did not begin at His birth in Bethlehem or at any other point in time. He has eternally existed with the Father (John 1:1–3; John 17:5). His incarnation marked His entrance into human history, not the beginning of His existence.
This distinction matters because Scripture presents the Son as co-Creator with the Father (John 1:3; Colossians 1:16–17). If all created things originated from Him, then He cannot be grouped with the created order. The eternal existence of the Son is therefore inseparable from the biblical witness of His deity.
Therefore, the eternal Sonship of Christ affirms both His eternal existence and His full deity, while preserving His personal distinction from the Father.
The Biblical Witness of the Son’s Eternality and Deity
The eternality of the Son means that He did not begin to exist at a point in time. His deity addresses His divine identity. These two are established throughout the Bible. The Son is presented as existing before creation and possessing the divine nature.
His Existence Before Creation
John’s Gospel opens with a profound declaration:
“In the beginning was the Word…” (John 1:1)
This beginning refers to the beginning of the created order, not the beginning of the existence of the Son. This truth is further affirmed by the role of the Son in creation. All things in heaven and on earth were created through Him and for Him (John 1:3; Colossians 1:15–17). Thus, it is only logical that as Creator, the Son existed before creation. And, Scripture indeed attests that He is before all things (Colossians 1:17).
His Possession of the Divine Nature
The divine identity of the Son is affirmed in the New Testament. John 1:1 says, “the Word was God”. Colossians 2:9 states that all the fullness of the Godhead dwells in Christ. Jesus does not possess only a lesser form of deity. He is fully God. Hebrews 1:3 describes the Son as the brightness of God’s glory and the express image of His person (Hebrews 1:3). Even the Father addresses the Son as God:
“Your throne, O God, is forever and ever.” (Hebrews 1:8)
Together, these passages affirm that the Son shares in the eternal identity of God. He is not merely a representative of God; He Himself is God.
His Eternal Glory
Jesus’ own words provide further evidence of His eternal existence and deity. In John 8:58, He declares,
“Before Abraham was, I AM.”
Christ does not say “Before Abraham was, I was”. He says “I AM”. That describes an existence that began in eternity and continues in the present. In John’s Gospel, the I AM declarations of Jesus carries profound theological significance. It reminds of the divine self-identification in Exodus 3:14. The Jews’ attempt to stone Him (John 8:59) demonstrates the gravity of His claim.
In John 17:5, Jesus also spoke of the glory He had with the Father before the world existed. This is not the language of a created being, or a being who began to exist at His incarnation. It is the testimony of the Son concerning His eternal glory and unique relationship with the Father.
His Divine Works and Honor
Jesus again highlights His unique relationship with the Father in John 5:19–23, where He describes His and the Father’s work in profound unity, including giving life and exercising judgment. Most significantly, Jesus states that all should honor Him just as they honor the Father (John 5:23). This is extraordinary. The Son does not claim the honor due to a prophet or an angel, but the honor due to the Father.
Then, Hebrews 1:3 ascribes a significant divine work to the Son— sustaining all things by His powerful word. These divine works and honours testify to His unique identity.
The cumulative evidence is clear: Christ possesses the fullness of deity, shares glory with the Father, pre-existed creation, participated in creation, and sustains creation.
The Incarnation of the Eternal Son of God
The incarnation is central to biblical Christology. It describes the entrance of the eternal Son of God into human history, through birth by a woman, for humanity’s redemption (Matthew 1:18–25; Luke 2:1–7; Galatians 4:4–5). John summed it up in these words:
“And the Word became flesh….” (John 1:14)
The incarnation of the Son is not to be mistaken for His beginning. John does not say that the Word began to exist; he says that the Word became flesh. The language of “became” portrays the Son as existing before His entrance into the world. In the incarnation, the eternal Son took on a genuine human nature, without ceasing to be who He eternally was.
The Father’s Only “Begotten”
John, in John 1:14 and 18, describes Christ as the Father’s only begotten. Many interpret the expression to mean that Jesus is a created being, or that He began to exist when He was born. Neither of these interpretations is supported by the meaning of the Greek word translated to “begotten”—monogenēs, which means “one and only” or “unique.” These meanings are reflected in the NIV rendering of “begotten” as “the one and only Son”.
Therefore, Christ being the begotten Son emphasizes His unique relationship with the Father. The writer of Hebrews, speaking of the unique Sonship status of Christ, asks which of the angels God ever addressed as Son (Hebrews 1:5; Psalm 2:7).
Historically, Christians have used the expression “eternal generation” to describe the eternal relationship of the Son with the Father: He is eternally the Son, not a creature brought into existence at some point before the world began.
Therefore, Jesus’ birth by Mary marks a genuine historical beginning to His earthly human life, not the beginning of His existence as the Son of God. Before His incarnation, He had eternally existed and shared glory with the Father (John 17:5). He did not become a divine person at His birth; He took upon Himself human nature while remaining fully divine.
Bethlehem was the place of the entrance of the Son into human history, not the beginning of His existence. The child born of Mary was the same eternal Word who was with God from the beginning, and who Himself is God. This truth safeguards both the reality of Christ’s humanity and the eternality of His deity.
Objections to the Eternal Deity of the Son
While the biblical witness is clear, those who oppose the eternality and deity of the Son, such as Muslims and Jehovah’s Witnesses, often cite certain biblical texts to argue that Jesus is a created being or lesser than God. We will consider two main objections within their literary and theological contexts.
Firstborn or First-created?
Jehovah’s Witnesses particularly cite Christ’s designation as “the firstborn over all creation” (Colossians 1:15) as prooftext that He is not the eternal God as orthodox Christianity believes, but He is a created being—the first and highest of God’s creation. They interpret “firstborn” as first-created.
This conclusion, however, ignores the immediate context and meaning of the Greek word translated firstborn—prototokos, which can both indicate birth order and superiority. For example, God declares to make David His firstborn (Psalm 89:27), but David is not the first human God created. The implication of “firstborn” is clear from God’s next declaration to make David “the highest of the kings of the earth”.
Likewise, Christ being the “firstborn over all creation” indicates His superiority, not being first-created. The immediate context supports this. Colossians 1:16–17 explains Christ’s superiority: all things in heaven and on earth were created through Him and for Him, and He is before all things. The passage distinguishes Christ from the created order by presenting Him as its Creator, Sustainer, and Supreme Lord. Reading firstborn as meaning first-created conflicts with the argument of the surrounding verses.
Another example is Revelation 3:14, where Christ is described as “the Beginning of the creation of God”. Some take this also to mean that Christ was God’s first creation. However, the word “beginning”, from the Greek archē, can also denote origin or source. The context determines its meaning.
The description fits into the wider biblical witness that creation came through the Son (John 1:1–3; Colossians 1:16). Christ is presented not merely as belonging to the created order, but as the Creator. Interpreting Revelation 3:14 as teaching that He was created would place it in tension with these explicit statements about the role of the Son in creating all things.
The Son’s Submission to the Father
This is a favorite of Muslims. They often cite passages describing the Son submitting to the Father as evidence against the deity of Christ. For example, in John 5:19, Jesus says:
“Most assuredly, I say to you, the Son can do nothing of Himself, but what He sees the Father do…”
Another passage is John 14:28, where Jesus declares, “My Father is greater than I.”
Then, 1 Corinthians 15:28, where Paul says:
“the Son Himself will also be subject to Him who put all things under Him, that God may be all in all.”
These passages, at first glance, appear to portray the Son as lesser than the Father. But when read in their respective contexts, they actually strengthen the deity of Christ, rather than contradict it.
John 5:19–23 presents the unity between the Son and the Father. The two do not only share a nature, but they also do the same work. What the Father does, the Son also does, including giving life and exercising judgment. Jesus was not denying His deity. In fact, in John 5:22–23, He laid claim to the same honor due to the Father.
In John 14:28, Jesus’ words about the Father being greater than Him was not in the context of nature but their roles within the redemption project.
We must distinguish between the divine identity and relationship of the Son to the Father in heaven and His humble status in the incarnation. In His eternal, heavenly existence, the Son is co-equal with the Father, sharing all the divine attributes equally with the Father. But for the purpose of redemption, the Son emptied Himself of His equality, took upon Himself the humble form of a servant, and died according to the Father’s plan (Philippians 2:5–8).
But after accomplishing redemption through His death and resurrection, He ascended to heaven, and resumed His position of preeminence, glory, and power (Philippians 2:9–11). These two truths must be held together rather than allowing one set of passages to cancel the testimony of another.
Then, in 1 Corinthians 15:24–28, Paul discusses the consummation of Christ’s mediatorial reign, when every opposing power will be subdued and the redemptive purpose accomplished. The submission of the Son in this context concerns the completion of His appointed mission. It does not, by itself, establish that He is lesser in being to the Father.
Why the Eternal Deity of the Son Matters
The eternal deity of the Son is not merely an abstract theological idea. It shapes our understanding of His person, His death and resurrection, His worship, faith in Him, and allegiance to Him. Who Jesus is determines the significance of what He has done and the confidence believers can place in Him.
It Makes His Revelation of the Father Authentic
John 1:18 presents the Son as the One who makes the Father known. Jesus declares in John 14:9, “He who has seen Me has seen the Father”. Christ does not merely give information about God; He reveals the Father most perfectly because of His eternal relationship with Him and His divine nature.
Again, this does not mean that the Son and the Father are the same person. Rather, the Son perfectly reveals the Father, making His character and purposes known in a way no created messenger could do. To know Christ is thus to encounter God’s definitive revelation.
It Makes His Redemptive Work Significant
Hebrews 2:14–17 explains that the Son partook of flesh and blood so that, through His death, He might defeat the one who had the power of death and deliver those held in bondage to its fear. In His incarnation, He became like us in order to serve as a merciful and faithful representative.
The incarnation was essential to this work: humanity needed a true representative who could genuinely share our condition and die on our behalf. Yet the One who undertook this mission was not merely another human. He was the eternal Son of God who entered human history to accomplish God’s redemptive purpose.
His deity does not make His humanity unnecessary, nor does His humanity diminish His deity. The Christian confession holds both together: the eternal Son truly became human and accomplished redemption through His death and resurrection.
It Provides the Foundation for Worship, Faith, and Assurance
When the resurrected Jesus appeared to the apostles, Thomas responded, “My Lord and my God!” (John 20:28). Jesus did not rebuke him for this confession. Instead, John presents the episode as a climactic testimony to Christ’s identity, consistent with his opening declaration that the Word was God (John 1:1).
Christ’s eternal nature also undergirds the believer’s assurance. Hebrews 7:24–25 explains that His priesthood is permanent and He is able to save completely those who come to God through Him, since He always lives to intercede for them. Unlike mortal priests whose ministries ended in death, Christ’s ministry is eternal.
The believer’s confidence therefore rests not in a temporary mediator but in the eternal Son of God, whose priesthood endures and whose saving work is sufficient.
The eternal deity of the Son matters because the One who reveals God, redeems humanity, receives our worship, and intercedes for believers is none other than the eternal Son. His identity gives enduring significance to His work and provides a firm foundation for Christian faith and assurance.
Conclusion
The total biblical witness establishes that Christ is not a created being but the eternal Son of God, who has eternally existed, shares the divine nature, and possesses the glory of the Father. His birth by Mary did not mark the beginning of His existence; it marked the incarnation of the eternal Son, who became flesh to accomplish humanity’s redemption.
To deny the eternality of the Son is to overlook the biblical witness concerning His existence before all things, His role in creation, and His divine identity. The same eternal Son who entered human history is the One through whom all things were created and in whom all things consist (Colossians 1:16–17).
The eternal deity of the Son is therefore not a peripheral doctrine but central to the Christian confession. Jesus Christ is the eternal Son of God—fully divine, distinct from the Father, and the perfect revelation of God to humanity. He is before all things, and His kingdom and priesthood endure forever.
