The phrases Jesus Christ, the Christ of faith, the Jesus of history, and Jesus the Divine Son all reflect significant themes pertaining to the central figure of the New Testament, Jesus of Nazareth. These concepts fall within a specialized area of theology known as Christology, which is a systematic “study of Christ” based on the full biblical picture derived from scripture.
A bit more formally, this field of study speaks to the Christian endeavor to map Jesus’ placement within “time and eternity, humanity and divinity, particularity and universality.” It answers how the life of a seemingly benign first-century Jewish rabbi could be so “relevant for all people and all times” (McGrath 2017, 207).
The present discussion maps Jesus’ Son-relationship in the triune unity of God, and the nature of his humanity. It then reflects on how the humanity of Jesus is relevant to the Christian’s personal walk before God.
Jesus the Son and the Trinity
The Trinitarian Formula
The divinity of Jesus is established in many passages of the New Testament. For example, Matthew closes with an appearance of Jesus where he affirms his authority “in heaven and on earth.” With this authority, he commissions his disciples for an international burden,
“Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit” (28:18–19 NRSV). [All Scripture references are from the New Revised Standard Version unless otherwise noted.]
Three themes are clear in this passage: Jesus’ divine authority, discipleship made in baptism, and the trinitarian language of Father, Son, and Holy Spirit. In the early generations of the church, the above trinitarian formula would represent a highly nuanced concept of monotheism affirmed to be in continuity with the “one God” of the Hebrew Bible.
What forced early Jewish Christians to accept this nuanced view of monotheism? The answer: the character and nature of Jesus did. It is not subversive of the “oneness” of God (Deut 6:4) but depends on the New Testament’s clarification that the “one God” is not a simplistic model. As the clarification argues, the Divine Son is not God the Father, nor is he the Holy Spirit. This raises tough questions that the historical church has discussed in earnest and in conflict for generations.
How do we map this out theologically?
The Divine Son Portrayed
We turn to the presence of Jesus and how He is portrayed in relation to the Father and the Holy Spirit.
In the first century, the prologue to the Fourth Gospel (John 1:1–3, 14) affirms that the person and nature of Jesus is the driving force to reshape the whole biblical landscape of the concept of God (Gen 1:1; Exod 20:11).
In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things came into being through him, and without him not one thing came into being... And the Word became flesh and lived among us, and we have seen his glory, the glory as of a father’s only son, full of grace and truth. (John 1:1–3a, 14)
Jesus not only pre-existed as the lógos at the time of creation (John 1:1), but he also “emptied” (ekénōsen) himself to take on the “form [morphē] of a slave”—a human (Phil 2:6–7). Leaning heavily on John 1:14, the Alexandrian theologian, Athanasius, concluded that this “human body” was taken by this same “Word of God” (Placher 2003, 184).
On this view, there was no room within this theology for Arius’ affirmation that Jesus the Son—the Word—was a created being who subsequently became divine. This view reduced Jesus to a creature impotent to redeem humanity (McGrath 2017, 217–19).
The Divine Association
As McGrath (2017, 214) chronicles, the divinity of Christ was one of the first major theological battles of the early church as it sought to hammer out its understanding of the contours of a very genuine human being in Jesus who, at the same time, was portrayed as being more than a mere human. The “battle” was not over the deity of Christ as such (that was established), but how to understand the relationship between his humanity and his divinity.
The divinity of Jesus was therefore accepted as true as his humanity—as affirmed in Chalcedon (AD 451)—which means that the question left to map out was the relationship between Jesus and the Father and the Holy Spirit.
The only way to do this is by evaluating Scripture (Jenson 2003, 194). Despite certain reservations, Jenson argues clearly that Peter’s application of the divine title “Lord” from Joel 2 (kyrios LXX) to Jesus in Acts 2:33–34 (kyrios) demonstrates that
the risen Christ, without violation of God’s singularity, does what only the God of Israel himself does, and that he does this precisely by virtue of his situation with the God of Israel. (2003, 194)
Jensen in Essentials of Christian Theology (2003)
Jensen points out that the emerging notion of association that comes from the word “with” points to the “inescapably observable fact” that the biblical narrative is framed by three divine characters in its drama (2003, 195): the God of Israel, Jesus his Son, and the life-giving Spirit of God.
Agreeing with Jenson (2003, 196), Jesus should not be viewed as a mere successive mode of God’s presence in time (modalism) or as the Father’s subordinate agent with the Spirit in time (subordinationism). Instead, Jesus maintains an eternally mutual and reciprocal relationship with the Father and the Spirit. For this reason, ancient Christians used an analogy inspired by the theater, that is to say, that the Father, the Son, and the Holy Spirit although three in persona (mask) are one in Divine substance. Another model is found in Martin Buber’s I-You relationship model (McGrath 2017,179–80).
Understanding the Humanity of Jesus
What, then, goes into mapping this theological tension of the Son and the Trinity?
Mapping the nature of Jesus’ humanity—in balance with his divinity—requires great caution. The traditional doctrine of the incarnation (literally, “becoming bodily”) affirms both the full humanity of Jesus and his divinity. Any attempt to isolate what is organically interwoven in the person and work of Jesus runs a high risk of distortion.
Overcompensating to account for the humanity of Jesus has typically been met with the “stamp” of heresy. Three, in particular, are Ebionism, Arianism, and Docetism (McGrath 2017, 214–20).
The roots of Ebionism are Jewish. It framed Jesus through the lenses of a human prophet, as called and anointed by the Holy Spirit. As a low Christology, Jesus is only a “spiritually superior” human. This does not align with the picture of his eternal pre-existence as Creator.
Plotted on another point on the map is Arianism (named after Arius), which called into question the “fully divine” and “fully human” affirmation due to an irreconcilable application of the Greek notion of divine impassability and the doctrine of the incarnation. God cannot be both changeable (fully human) and transcendent (fully divine), therefore, the incarnation strikes at the perfect nature of the one God. Jesus must therefore be a “superior created being” with nothing divine to report. This failed to account for the actual testimony of the gospels where in fact this is possible.
Meanwhile, Docetism affirmed, with its hardline separation of God and the present evil world of matter (due to its gnostic foundation), the divine incarnation of John 1:14 was nothing more than “pretend.” The heresy’s name (or tendency) is derived from the Greek word dokéō (“to seem”) affirming Jesus only “seemed” to have a body in which he suffered and died, making the incarnation “into a fake” (Placher 2003, 183). Scripturally, the work of Christ is dependent on the fully human (Luke 24:38–39) and fully divine Jesus manifested in the death of the cross and resurrection from the dead (Rom 1:3–4).
Similarly, the opening line of 1 John affirms the humanity of the “Word of Life”: “what we have heard, what we have seen with our eyes, what we have looked at and touched with our hands” (1:1).
Likewise, in the second century CE, Ignatius of Antioch (ca. 35–ca. 110) stressed his concern to the Christians of Trallia that they should guard against (“be deaf,” kōphóthēte 9.1) anything which undermines the humanity of Christ with the following words:
Jesus Christ, who was of the family of David, who was the son of Mary; who really was born, who both ate and drank; who really was persecuted under Pontius Pilate, who really was crucified and died while those in heaven and on earth and under the earth look on; who, moreover, really was raised from the dead when his Father raised him up, who—his Father, that is—in the same way will likewise also raise us up in Christ Jesus who believe in him, apart from whom we have no true life. (“To the Trallians” 9.1–2)
Ignatius of Antioch, “To the Trallians” 9.1-2
The example of Ignatius is interesting because it is early and strongly affirms Jesus’ human form, “who really” (hos alethōs) an adverb repeated four times to assert what is true, actual because it corresponds to what is really so (BDAG 44). For Ignatius, Jesus actually was born, ate and drank, persecuted, crucified and died, and raised from the dead. Ignatius saw denying the humanity of Christ as subversive to the soteriological (the saving, redeeming) and eschatological (end times, fulfilling) work of Christ.
What Does This Mean?
What then does it mean for the Christian that God became flesh to redeem us in the person of Jesus Christ? Two extremes must be cautioned against here. One extreme is to moralize the life of Jesus (1 Pet 2:21), and as such reduces Jesus to a mere good teacher. Another extreme is to make Jesus’ life and teaching into a disjointed symbolic presence of God (i.e., Paul Tillich).
The humanity of Jesus provides me with a great deal of assurance as a believer that God knows through Christ the human plight. Jesus has “assumed all” and can, therefore “heal all” of humanity (Placher 2003, 184). When the “name” Immanuel (“God is with us”) is given to Jesus (Matt 1:23) the associated promise is that “he will save his people from their sins (Matt 1:21). God’s presence in the human child to be born provides a personal locus that can be isolated to time, space, and history.
For all humans, it then becomes quite clear that God is joining the human continuum to reconcile not only “us” but also “the world to himself” in Christ (2 Cor 5:18–19). Paul’s application has massive personal repercussions,
“if anyone is in Christ, there is a new creation: everything old has passed away; see, everything has become new!” (5:17)
The humanity of Jesus is not simply a modal expression of God, but God entering into time and space to save, forgive, reconcile, and renew humanity and creation.
It provides the seedbed to take the particular localized Jesus and affirm his enduring value for all humans for all time. As Ignatius wrote, God “will likewise also raise us up in Christ Jesus who believe in him, apart from whom we have no true life” (“To the Trallians” 9.2).
Truly, the humanity of the God-Man Jesus is relevant for the Christian’s personal walk before God because it is the seedbed for all our hopes, especially, hope for the resurrection (1 Cor 15:12–19).
