"Thomas answered and said to Him, 'My Lord and my God!'"
— John 20:28 (NASB 1995)

The deity of Jesus Christ — the confession that the man from Nazareth who walked the roads of Galilee was crucified under Pontius Pilate and rose from the dead on the third day is Himself fully and truly God — is the theological center of gravity of the entire New Testament and the culmination of all Old Testament prophetic expectation. To affirm the deity of Christ is not a secondary theological opinion or a denominational particularity; it is the irreducible heart of the Christian faith. To deny it is to destroy Christianity at its foundation.

Scripture approaches this truth from multiple directions simultaneously: through the explicit declarations of Jesus about His own identity, through the titles ascribed to Him by His apostles, through the actions He performed that only God can perform, through the worship He accepted, through the Old Testament passages applied to Him that were originally addressed to YHWH, and through the theological logic of the atonement itself — for only God incarnate could bear the infinite weight of humanity's sin and satisfy the demands of a perfectly holy God.

The oldest extant confession of the church — κύριος Ἰησοῦς (kyrios Iēsous, "Jesus is Lord," Romans 10:9; 1 Corinthians 12:3) — employed the Greek term κύριος (kyrios; BDAG 576), which was the standard Septuagint rendering of the divine name יְהוָה (YHWH; BDB 217, HALOT 394). To confess Jesus as Kyrios was to assign to Him the covenant name of Israel's God. This was not theological evolution; it was the immediate, apostolic, Spirit-inspired recognition of who Jesus had revealed Himself to be.

Pliny the Younger, the Roman governor of Bithynia-Pontus, writing to Emperor Trajan ca. AD 112, reported that Christians "sing hymns to Christ as to a god" (carmen Christo quasi deo dicere, Epistulae X.96). This secular Roman document, written less than 80 years after the resurrection, confirms that the divine worship of Christ was a fundamental and universal feature of the earliest Christian communities — not a later theological development. (Perseus Digital Library, Pliny Letters 10.96)

Larry Hurtado (University of Edinburgh), in his landmark historical-critical work Lord Jesus Christ: Devotion to Jesus in Earliest Christianity (Eerdmans, 2003), demonstrates through exhaustive historical analysis that the veneration of Jesus as a divine figure arose within the earliest Jewish-Christian communities and cannot be explained as a gradual mythologization. Hurtado writes: "The devotion to Jesus that we see in our earliest sources represents a genuine mutation in Jewish monotheism — a sudden, massive, and historically extraordinary elevation of a human figure to divine status alongside God, within a community deeply committed to Jewish monotheism" ^[1]. (Eerdmans: Lord Jesus Christ)

This series works through the biblical case for the deity of Jesus Christ across eight posts, moving from the shape of the argument itself to the Old Testament foundations, the four Gospels, Acts, the epistles, Revelation, and finally the historic denials of the doctrine.

Summary: The Cumulative Case

The deity of Jesus Christ is not established by one or two isolated proof-texts that require special pleading. It is established by the convergence of multiple independent lines of evidence throughout the entire canon of Scripture:

1. OT prophecy — The Messiah is identified with YHWH Himself: Immanuel (Isaiah 7:14), Mighty God (Isaiah 9:6), YHWH Tsidkenu (Jeremiah 23:6), the YHWH who is pierced (Zechariah 12:10), the one whose way is prepared as YHWH (Isaiah 40:3; Malachi 3:1), the Ancient of Days' eternal counterpart (Daniel 7:13–14).

2. Jesus' explicit self-claims — I AM (John 8:58; Mark 14:62), equal with the Father (John 5:18), one with the Father (John 10:30), seen the Father by seeing Him (John 14:9), pre-existent glory (John 17:5), the eternal Alpha and Omega (Revelation 22:13).

3. Divine prerogatives exercised — Forgiveness of sins (Mark 2:5–7), creation (John 1:3; Colossians 1:16), sustaining the cosmos (Hebrews 1:3; Colossians 1:17), universal judgment (John 5:22; Acts 17:31), resurrection from the dead (John 2:19–21; John 11:25).

4. Divine titles received — Lord/Kyrios/YHWH (Philippians 2:9–11), God (John 1:1; John 20:28; Romans 9:5; Titus 2:13; Hebrews 1:8; 1 John 5:20), True God (1 John 5:20), Alpha and Omega (Revelation 22:13), First and Last (Revelation 1:17), the Only Savior (Titus 2:13; cf. Isaiah 43:11).

5. Divine worship received and accepted — Throughout His ministry, at the resurrection, commanded of angels, and in the eternal worship of heaven (Revelation 5:12–14) — worship that no prophet, apostle, or angel ever accepted.

6. Historical testimony — The earliest non-Christian witnesses (Pliny, Tacitus, Josephus) confirm that Jesus' followers worshipped Him as God from the very beginning — not as a later theological development. The resurrection — the central historical claim of Christianity — was witnessed by over 500 people (1 Corinthians 15:6) and stands as the ultimate vindication of Jesus' claims.

The appropriate and only fitting response is that of Thomas: "My Lord and my God!" (John 20:28)
