## Theological force

### *Dikaios* of God

God is supremely *dikaios*, His character, judgments, and ways are perfectly righteous:
- **[Romans 3:26](/codex/romans-3-26/)**, God is *dikaion kai dikaiounta*, "just and the justifier" of those who have faith in Jesus
- **[Revelation 16:5](/codex/revelation-16-5/), [7](/codex/revelation-16-7/); 19:2**, God's judgments are *dikaiai*

### *Dikaios* of Christ

Christ is *the Righteous One*:
- **[Acts 3:14](/codex/acts-3-14/)**, "the *dikaion* and Holy One" (Peter's sermon)
- **[Acts 7:52](/codex/acts-7-52/)**, "they killed those who had previously announced the coming of the *dikaiou*" (Stephen)
- **[Acts 22:14](/codex/acts-22-14/)**, "to see the *dikaion*" (Ananias to Paul)
- **[1 John 2:1](/codex/1-john-2-1/)**, "we have an Advocate with the Father, Jesus Christ the *dikaion*"
- **[1 Peter 3:18](/codex/1-peter-3-18/)**, "Christ also died for sins once for all, the *dikaios* for the unrighteous"

Christ as the *Dikaios* fulfills the OT-Servant-Messiah pattern ([Isaiah 53:11](/codex/isaiah-53-11/), *tzaddiq avdi*) and grounds substitutionary atonement: the *dikaios* dies for the *adikoi*.

### *Dikaios* of believers

Believers are *dikaioi* in two senses:

**(1) Imputed righteousness**, the Reformation core:
- [Romans 1:17](/codex/romans-1-17/) (citing [Habakkuk 2:4](/codex/habakkuk-2-4/)), "the *dikaios* by faith shall live"
- [Romans 4:3](/codex/romans-4-3/) (citing [Genesis 15:6](/codex/genesis-15-6/)), "Abraham believed God, and it was credited to him as *dikaiosynēn*"
- [2 Corinthians 5:21](/codex/2-corinthians-5-21/), "He made Him who knew no sin to be sin on our behalf, so that we might become the *dikaiosynē theou* in Him"

**(2) Practical / experiential righteousness**, sanctification:
- [1 John 3:7](/codex/1-john-3-7/), "the one who practices *dikaiosynēn* is *dikaios*"
- [1 John 2:29](/codex/1-john-2-29/), "everyone who practices *dikaiosynēn* has been born of Him"
- [Matthew 5:6](/codex/matthew-5-6/), "blessed are those who hunger and thirst for *dikaiosynēn*"
- [Matthew 5:20](/codex/matthew-5-20/), disciples' *dikaiosynē* must surpass that of scribes and Pharisees

The Reformation: *imputed* righteousness is the legal-forensic foundation; *experiential* righteousness is the resulting fruit. The believer is *declared dikaios* (justification) and *progressively becomes dikaios* in lived holiness (sanctification).

### [Habakkuk 2:4](/codex/habakkuk-2-4/), *the dikaios shall live by faith*

The most-cited OT quote in the NT ([Romans 1:17](/codex/romans-1-17/); [Galatians 3:11](/codex/galatians-3-11/); [Hebrews 10:38](/codex/hebrews-10-38/)). The Reformation rallying cry, *sola fide*, is anchored here. The *dikaios* lives by *pistis*, not by works, ritual, or self-justification.

## Patristic / scholarly note

The *dikai-* word family is central to the Reformation vs Roman Catholic dispute over justification (see [G1344 - dikaioo](/codex/g1344-dikaioo/) for fuller treatment). Conservative Protestant: imputed-forensic; Roman Catholic: infused-grace. Modern: New Perspective on Paul (Wright, Sanders, Dunn) reframes the dispute around covenantal-faithfulness.
