Who Is the King Eternal?

An Exegetical and Theological Study of 1 Timothy 1:17

“Now unto the King eternal, immortal, invisible, the only wise God, be honour and glory for ever and ever. Amen.”
— 1 Timothy 1:17 (KJV)

Introduction

Few verses have inspired as much doxological awe as 1 Timothy 1:17. Yet behind its familiar cadence lies a crucial interpretive question: Who is the “King eternal”?

Trinitarian interpreters often assume that Paul’s doxology refers to Jesus Christ, reasoning that because the preceding verses (vv. 12–16) express thanksgiving to Christ, the following praise must also address Him.

However, a close reading of the text—literary, linguistic, and theological—reveals a different picture. The doxology of verse 17 aligns precisely with Paul’s consistent pattern of glorifying God the Father, who is the eternal King, while Christ is His anointed and appointed Lord through whom divine mercy is manifested.

1. The Immediate Context of 1 Timothy 1:17

The opening of 1 Timothy clearly distinguishes between God and Christ Jesus:

• 1:1–2 – “Paul, an apostle of Jesus Christ by the commandment of God our Saviour and Christ Jesus our hope.”

• 1:11 – “According to the glorious gospel of the blessed God.”

Verses 12–16 form a thanksgiving to Christ, focusing on Paul’s personal experience of mercy and calling. Then, in verse 17, Paul transitions with νῦν δέ (“Now unto…”), returning to the God already introduced in the epistle’s opening.

The literary flow is therefore:

God (vv. 1–2, 11) → thanksgiving to Christ (vv. 12–16) → doxology to God (v. 17).

Such movement—from divine action in Christ to doxology to God—is a hallmark of Pauline theology (cf. Eph 1:3–7; 2 Cor 1:3–4).

2. The Greek Text and Its Theological Force

Τῷ δὲ βασιλεῖ τῶν αἰώνων, ἀφθάρτῳ, ἀοράτῳ, μόνῳ θεῷ, τιμὴ καὶ δόξα εἰς τοὺς αἰῶνας τῶν αἰώνων· ἀμήν.

Each of these divine epithets belongs, in Paul’s usage, to God the Father:

The description coheres perfectly with biblical monotheism centered on the Father: eternal kingship, immortality, and invisibility are never ascribed to Christ directly, but to God as His source.

3. The Pattern of Pauline Doxology

Paul’s letters display a consistent structure of worship and attribution:

1 Timothy 1:17 fits this pattern seamlessly. In each case, Paul’s doxology culminates in praise to the one God, not to Christ. Even when Christ is exalted, it is to the glory of God the Father (Phil 2:11).

4. The Old Testament Background: The Everlasting King

Paul’s phrase “King of the ages” (βασιλεὺς τῶν αἰώνων) directly echoes Jeremiah 10:10:

“The Lord is the true God; He is the living God and the King of the ages (βασιλεὺς τῶν αἰώνων).” Septuagint reading

This title is exclusively used of YHWH, never of the Messiah.
Paul’s borrowing of this language thus grounds his doxology in the monotheistic tradition of Israel, identifying the “King eternal” with the Father, not with His anointed Son.

5. Was Jesus Always King?

If 1 Timothy 1:17 referred to Christ, the title “King eternal” would imply that Jesus has always reigned as King.
Yet the New Testament consistently teaches that Christ was made King by divine appointment.

a. Christ’s Kingship Was Granted, Not Innate

• Acts 2:36 – “God has made this same Jesus … both Lord and Christ.”

• Philippians 2:9–11 – “Therefore God has highly exalted Him and given Him a name above every name.”

• Luke 22:29–30 – “I appoint unto you a kingdom, as my Father has appointed unto me.”

• 1 Corinthians 15:24–28 – Christ reigns until He delivers the kingdom to God the Father.

Christ’s royal authority begins with His exaltation; it is received, not eternal in essence.

b. God’s Kingship Is Eternal and Inherent

By contrast, the Old Testament repeatedly affirms the eternal sovereignty of God:

• Psalm 10:16 – “The LORD is King for ever and ever.”

• Psalm 29:10 – “The LORD sits enthroned as King forever.”

• Jeremiah 10:10 (LXX) – “The LORD … is the King of the ages.”

Only God fits the description of “King eternal.”

c. The Distinction Between the Eternal King and the Appointed King

Paul’s “King eternal” therefore cannot describe the one who became King through resurrection, but the one who has always reigned—God, the Father.

6. Theological Synthesis: The King and His Christ

Paul’s theology preserves both the monarchy of God and the mediatorship of Christ.
Christ reigns by the will of the eternal King; His authority is functional and redemptive, not ontological equality with the Father.

7. A Note on Trinitarian Misreading

Trinitarian interpreters often argue that because Paul has just thanked Christ, the doxology must continue to address Him.
Yet this ignores Paul’s repeated stylistic habit of moving from Christ’s saving work to praise of God (cf. Rom 16:27; Eph 3:21).

Moreover, the attributes “immortal” and “invisible” cannot coherently describe Christ incarnate, who died and was seen.
To read verse 17 as addressed to Christ would make Paul contradict his own preceding language (1 Tim 6:16), where only God possesses immortality and invisibility.

8. Conclusion: The Eternal King and the Mediatorial Lord

The evidence—textual, grammatical, contextual, and theological—leads to a single conclusion:
1 Timothy 1:17 is a doxology to God the Father.

Paul’s thought flows naturally:

• Christ shows mercy and appoints Paul (vv. 12–16).

• Paul’s heart rises in thanksgiving to the One who sent Christ—the King eternal, immortal, invisible, the only God.

Thus, the apostle’s praise encapsulates the entire Pauline vision of divine order:
the Father as the eternal King and source of all glory,
and Christ as the appointed mediator through whom that glory is revealed.

“Now unto the King eternal, immortal, invisible,
the only wise God,
be honour and glory for ever and ever. Amen.”
