Jesus' Divinity and Humanity in Christian Theology
Christian theology affirms that Jesus Christ is both fully divine and fully human, a foundational concept for understanding his person and work [6]. This dual nature is often referred to as the hypostatic union.
The divinity of Jesus is attested throughout Scripture. He is identified as "God" (Greek: Theos) [1], and the New Testament frequently attributes divine qualities and actions to him. For instance, the apostle John states that "the Word was God" and that "the Word became flesh" (John 1:1, 14) [6]. This "Word" (Greek: Logos) is understood to be Jesus Christ. The apostle Paul also speaks of Christ as the one "in whom dwelleth all the fulness of the Godhead bodily" (Colossians 2:9) [7]. This means that the entire essence of God resides within Jesus' human nature in a unique and exalted way [7]. Jesus' divine majesty and glory are subjects of praise, recognizing him as the "only begotten of the Father" and the "brightness of his glory" [8]. The doctrine of the Trinity, though the word itself is not found in Scripture, expresses the belief that God is one being subsisting in three distinct persons: Father, Son (Jesus Christ), and Holy Spirit [2]. The grace of Christ is often presented first in benedictions, leading to the love of God the Father, demonstrating his co-equal status within the Godhead [4].
Equally crucial to Christian doctrine is Jesus' full humanity. The New Testament emphasizes that Jesus truly "became flesh" (John 1:14) [6]. This concept was startling to both Greeks, who separated the divine from the mundane, and Jews [6]. His humanity was not partial but complete, encompassing a true body and a reasonable soul [3, 7]. Evidence for his humanity includes his conception in the Virgin Mary's womb, his birth, and his partaking of "flesh and blood" [3]. Jesus experienced human limitations and emotions: he was circumcised, grew in wisdom and stature, wept, hungered, thirsted, slept, and experienced weariness [3]. The apostle Paul highlights Jesus' human nature by calling him "the man Christ Jesus" (1 Timothy 2:5) and noting that he was "made of a woman, made under the law" (Galatians 4:4-5) [3].
The necessity of Jesus' human nature is tied to his mediatorial office [3]. As the second Adam, Christ founded a new humanity, distinct from the one established by the first Adam. While Adam represented a natural, earthly humanity enslaved to sin and death, Christ represents a spiritual, heavenly humanity purified and destined for life [5]. His human nature enabled him to be a sympathetic high priest, one who could be "made like unto his brethren" in all things, so that he might be a merciful and faithful high priest in things pertaining to God, to make reconciliation for the sins of the people (Hebrews 2:17) [3].
The complete and inseparable union of these two natures—divine and human—in one person is a bedrock of Christian understanding [6]. This union means that Jesus is 100% divine and 100% human, without either nature being diminished or confused.

Adam represents the natural (physical) body and Christ the spiritual (resurrection) body.
