δικαιοσύνη

In 1545, a year before his death, Martin Luther wrote a preface to the first volume of his collected Latin works. In it he told a story about how he had come to understand a single phrase in Romans 1:17 — the righteousness of God. For years, he wrote, he had hated that phrase. He had read it as God’s punishing justice — the attribute by which God judges sinners — and had concluded that the gospel itself was offering him only further condemnation. He could not stop sinning. The “righteousness of God” would always find him out.

Then he saw something. Luther wrote that he came at last, after long meditation and considerable suffering, to see that “the righteousness of God” was not God’s just attribute on display against him, but God’s gift-righteousness given to those who believe. The phrase he had hated became the phrase that set him free.

That discovery did not happen in a vacuum. It happened over months and years, in the study and the lecture hall and the confessional. Luther himself dated it variously. But it is the moment Lutheran historians have called the Turmerlebnis — the tower experience — and the Greek word at the center of the discovery is dikaiosynē: righteousness.

The chapter on dikaioō (Chapter 19) was about the verb by which God declares the sinner righteous. This chapter is about the noun for the righteousness God declares the sinner to have. The Lutheran answer, recovered by Luther through long study and considerable agony, is that this righteousness is not the sinner’s own. It is Christ’s righteousness, given as gift, received by faith. The justified sinner stands before God clothed in a righteousness not his own — and that righteousness, foreign to him by nature, becomes his fully and irrevocably by God’s free declaration.

The Word

δικαιοσύνη (dikaiosynē), pronounced dee-kai-oh-SOO-nay. A feminine noun, first declension. The family is one of the largest in the New Testament: dikaios (δίκαιος, “righteous, just”), dikaioō (δικαιόω, “to justify”), dikaiōma (δικαίωμα, “righteous decree, righteous act”), dikaiōsis (δικαίωσις, “justification”), dikaiōs (δικαίως, “righteously”). The root is dikē (δίκη), the Greek word for justice or judgment — in some texts a personified goddess of justice, in others simply the abstract noun for the right ordering of things.

In classical Greek, dikaiosynē named justice in the sense of giving each what is due. Plato treated it as one of the four cardinal virtues, alongside wisdom, courage, and moderation. A dikaios person was someone who acted justly in his dealings with others, paid what he owed, kept his agreements, gave each person their proper share. Dikaiosynē in this sense was an ethical category — a quality of human character, observable in conduct.

The Septuagint took this Greek word and stretched it to carry the Hebrew tsedeq (צֶדֶק) and tsedaqah (צְדָקָה), which had a wider range. The Hebrew terms could mean justice in the Greek sense, but they could also mean God’s saving covenant action — His acting in faithfulness to deliver His people, vindicate the oppressed, set things right. When the prophets spoke of God’s tsedeq, they often meant not His attribute of justice in the abstract but His coming to save. The Septuagint translators used dikaiosynē to render this Hebrew background, and the New Testament writers inherited a word weighted both with Greek ethical content and with Hebrew covenant-saving content.

This is one of those words where the etymology gives you only part of the meaning. To hear what the New Testament does with dikaiosynē, you have to hear both the Greek ethical sense (right conduct, right standing) and the Hebrew covenant-saving sense (God’s coming to make things right). Paul’s most consequential uses of the word run on both tracks at once.

Range of Meaning

In its New Testament usage, dikaiosynē covers:

• God’s attribute of righteousness — His holy and just character considered in itself.
• God’s saving action — His coming to make things right, deliver His people, vindicate His covenant. The Hebrew prophetic sense, inherited through the Septuagint.
• The gift-righteousness God gives the believer in justification — the meaning Luther recovered in Romans 1:17. This is the dominant Pauline use in justification contexts.
• The righteous conduct expected of those who have been declared righteous — the sanctification dimension, the actual living of the Christian life as a righteous life.
• What is right or just in general — the residual classical Greek sense, occasionally appearing in passages about social or ethical justice.

The center of gravity in Paul’s letters is the third sense — gift-righteousness — though the second sense (God’s saving action that delivers this gift) is usually in the background, and the fourth sense (sanctification) is the fruit that follows. The first sense (attribute) and the fifth sense (general justice) appear in some passages but are not the chapter’s main concern.

Where You’ll Meet It

“For in it the righteousness of God is revealed from faith for faith, as it is written, ‘The righteous shall live by faith.’” (Romans 1:17, ESV)

The verse Luther wrestled with for years. The “righteousness of God” (dikaiosynē theou) is revealed in the gospel — and revealed “from faith for faith,” meaning received by faith and intended for faith. Luther came to read this as the gift-righteousness God gives to those who believe, rather than as God’s attribute of justice operating against the unrighteous. The reading changed the Reformation, and it changes Christian lives whenever it is recovered.

“But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it — the righteousness of God through faith in Jesus Christ for all who believe.” (Romans 3:21–22, ESV)

The verse Paul builds his Romans argument toward. The dikaiosynē theou has been manifested — made visible, made available — apart from the law. It comes “through faith in Jesus Christ” (the pistis Christou phrase we treated in Chapter 19 on dikaioō). It is for all who believe. The Old Testament had borne witness to it; the New Testament now delivers it.

“For if, because of one man’s trespass, death reigned through that one man, much more will those who receive the abundance of grace and the free gift of righteousness reign in life through the one man Jesus Christ.” (Romans 5:17, ESV)

Paul’s Adam-Christ contrast. Righteousness is described here as “the free gift” (dōrea) and “the abundance of grace.” Receiving it is not earning it; it is taking what has been given. The result is reigning in life — the eschatological dignity restored to those who have been given Christ’s righteousness.

“For, being ignorant of the righteousness of God, and seeking to establish their own, they did not submit to God’s righteousness.” (Romans 10:3, ESV)

The verse that names the central religious problem. The Israel of Paul’s day — and by extension, every religious person of every era — is “ignorant of the righteousness of God” and tries to establish “their own” righteousness instead. The contrast is the contrast between gift-righteousness and self-righteousness. The latter is the human default. The former is what the gospel reveals.

“For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.” (2 Corinthians 5:21, ESV)

The most concentrated statement of imputed righteousness in the New Testament. Christ became what He was not (sin, on the cross, for us) so that we might become what we are not (the righteousness of God, in Him, by faith). The exchange is total. His sinlessness is taken into the place of our sin; His righteousness is given into the place of our unrighteousness. Lutheran theology has called this the “Great Exchange” — though the language predates the Reformation and is found in some of the church fathers.

“And be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith…” (Philippians 3:9, ESV)

Paul’s autobiographical confession. He had a righteousness of his own — by the standards of the law, blameless — and he has counted it as loss in order to have Christ’s righteousness instead. The verse names the two righteousnesses (his own, from the law; Christ’s, through faith) and chooses between them. Lutherans hear this verse the way Paul wrote it: the believer has Christ’s righteousness, not his own.

“And because of him you are in Christ Jesus, who became to us wisdom from God, righteousness and sanctification and redemption…” (1 Corinthians 1:30, ESV)

The verse Lutherans have cited for five centuries to summarize the substance of saving faith. Christ Himself became our righteousness. The gift is not a quality detached from Him; the gift is Him. To have righteousness is to have Christ. The believer’s standing is not in a credit balance on a heavenly ledger; the believer’s standing is in a Person.
