What does Christology study or explore?

Definition and Scope

Christology is the field of study that focuses on the identity, nature, and work of Jesus the Messiah. It addresses how Scripture and historical Christian teaching define His divinity, humanity, mission, and place in the eternal plan. The subject encompasses titles given to Jesus in the Bible, explanations of His nature, and how He accomplishes salvation.

This exploration draws on Old Testament prophecies, New Testament writings, early church doctrinal statements, and subsequent historical reflections. It examines the deeply interwoven scriptural testimonies revealing how God the Son became flesh to redeem humanity, while retaining His divine nature.


Biblical Foundations

Christology finds its primary source in the Bible. The Old Testament foreshadows the coming of Messiah (Hebrew for “Anointed One”), while the New Testament testifies to Jesus as the promised Christ. Scriptural prophecy, eyewitness testimony, letters (Epistles), and apostolic teaching all combine to paint a unified portrait of Jesus.

Genesis 3:15 is often identified as the earliest promise of a coming Redeemer who would bruise the serpent’s head.

Isaiah 53 prophetically portrays a Suffering Servant who takes on the iniquities of humanity.

John 1:1,14 declares, “In the beginning was the Word, and the Word was with God, and the Word was God… The Word became flesh and made His dwelling among us.”

This biblical groundwork establishes that from creation forward, God intended salvation through His Messiah, culminating in the life, death, and resurrection of Jesus.


Titles and Roles of Christ

Christology often examines the many titles used of Jesus in Scripture, each revealing aspects of His identity:

1. Son of God – Emphasizes divine nature (Matthew 3:17).

2. Son of Man – Reflects His incarnation as fully human (Mark 2:10), echoing Daniel 7.

3. Messiah (Christ) – The Anointed One promised in the Old Testament (Matthew 16:16).

4. Lord – Declares authority. The apostles recognized Jesus as the Lord of all (Romans 10:9).

5. Lamb of God – Signals sacrificial atonement (John 1:29).

Examining these titles illustrates His dual nature—fully God and fully man—and how He accomplishes the redemption plan foretold throughout the Old Testament.


The Person of Christ

Christology centers on understanding how Jesus can be both fully God and fully human in one unified Person. Known as the “hypostatic union,” this concept upholds that Jesus is without confusion or mixture of natures, yet truly divine and truly human.

1. Full Deity – Passages such as John 8:58 record Jesus saying, “Before Abraham was born, I am!” echoing God’s self-disclosure in Exodus 3:14.

2. Full Humanity – Verses such as Hebrews 2:14 emphasize that He “shared in their humanity.”

Early doctrinal statements like those from the Council of Nicaea and the Council of Chalcedon upheld this biblical teaching against heretical claims that tried to deny either His deity or humanity.


The Work of Christ

At the heart of Christology is the mission Jesus undertook:

1. Incarnation – Jesus took on a human body (John 1:14) to reveal God’s character and dwell among us.

2. Atonement – By His crucifixion and shedding of His blood, He paid the ransom for sin (Romans 3:24–25).

3. Resurrection – Scripturally established as the cornerstone of salvation (1 Corinthians 15:3–4). Eyewitness accounts, including those recorded in the Gospels, affirm that He rose bodily from the tomb, fulfilling prophetic signs (Psalm 16:10).

4. Ascension and Reign – After appearing to many, Jesus ascended to the Father’s right hand (Acts 1:9–11). He reigns as King and will return in glory (Revelation 19:11–16).

Christology therefore highlights how His redemptive work was foreordained before creation and validated by His resurrection—an event well-documented by New Testament sources and corroborated historically by the transformation of His followers.


Key Scriptural Passages

John 1:1–18: Presents the deity of Christ, proclaiming Him as the eternal Word made flesh.

Philippians 2:6–11: Describes Christ’s self-emptying, obedience unto death, and exaltation by God.

Hebrews 1:1–4: Portrays Jesus as the radiance of God’s glory and exact expression of His nature.

1 Corinthians 15: Lays out eyewitness evidence for the resurrection and underlines its indispensable role in Christian faith.

Colossians 1:15–20: Calls Him the “image of the invisible God, the firstborn over all creation,” underscoring His rightful supremacy.


Historical and Archaeological Insights

Although the heart of Christology rests upon revealed Scripture, numerous external sources and archaeological findings reinforce its teachings:

1. Ancient Writings – Jewish historian Flavius Josephus and Roman historian Tacitus refer to Jesus and early Christian belief in His resurrection.

2. Manuscript Evidence – More than 5,000 Greek New Testament manuscripts exist, providing a strong foundation to confirm textual consistency and reliability.

3. Archaeological Sites – Excavations in areas such as Jerusalem, Nazareth, and Capernaum demonstrate the historical authenticity of biblical settings, adding credibility to the accounts about Jesus.

These materials corroborate the existence, ministry, and aftermath of Jesus’ life and resurrection, supporting core Christological beliefs.


Practical Implications

Christology shapes not only doctrine but also daily faith practice:

Worship – Recognizing Jesus as God incarnate drives believers to worship Him wholeheartedly (John 20:28).

Salvation – Affirms that trust in Christ’s atoning sacrifice is the exclusive path to restoration with God (John 14:6).

Identity and Purpose – Believers find their purpose summed up in worshiping and glorifying God by following Christ’s example of holiness, humility, and service (Philippians 2:4–5).

Understanding the person and work of Christ encourages believers to live in loving obedience and share the message of redemption with others.


Conclusion

Christology explores who Jesus is—eternal God the Son who became fully human—what He has done through His life, death, and resurrection, and how these truths shape all of Christian belief and practice. This field of study aids in comprehending the grand narrative of Scripture, revealing the magnificent reality of God drawing humanity to Himself through His Messiah. As believers delve deeper into Christology, they gain a more profound appreciation for the saving grace accomplished by the One who is both fully God and fully man.
