Righteousness is an important theme in both Testaments of the Bible. The concept includes faithfulness, justice, uprightness, correctness, loyalty, blamelessness, purity, salvation, and innocence. Because the theme is related to justification, it has important implications for the doctrine of salvation (see also Justification).

Old Testament

Divine righteousness. Being careful to avoid imposing Western philosophical categories onto OT texts, we may say that the core idea of righteousness is conformity to God’s person and will in moral uprightness, justness, justice, integrity, and faithfulness. Behind the many and varied uses of righteousness language in the OT stands the presupposition that God himself is righteous in the ultimate sense (e.g., Ezra 9:15; Isa. 45:21; Zeph. 3:5). Righteousness is the expression of his holiness in relationship to others (Isa. 5:16), and all other nuances of righteousness in the biblical texts are derived from this. Either he reveals what is right or demonstrates rightness in his activity. God’s decrees and laws are righteous (Deut. 4:8; Ps. 119); his will is righteous (Deut. 33:21); his acts are righteous (Judg. 5:11; 1 Sam. 12:7; Ps. 71:24); his judgments are righteous (Ps. 7:11); and he always judges with righteousness (Ps. 96:13). In OT texts, divine righteousness is often linked to God’s saving activity, particularly in Psalms (e.g., Ps. 71) and in Isa. 40–66. Divine righteousness is much broader than deliberative justice (i.e., punishing the wicked and rewarding the righteous), though it does include it.

Human righteousness. Related to humans, righteousness is often found as the opposite of wickedness. Righteousness often occurs in evaluative contexts, where it relates to proper conduct with respect to God, the order of the world as he created it, the covenant, or law (e.g., Deut. 6:25). God reigns in righteousness and justice (e.g., Ps. 97:2), and humans should align their conduct with this righteous reign. Righteousness can be expressed as personal integrity with phrases such as “my righteousness” (2 Sam. 22:21, 25; Ps. 7:8) and “their righteousness” (1 Sam. 26:23). Unrighteousness is found in poetic parallel to injustice (e.g., Jer. 22:13); the unjust are parallel with the wicked (Ps. 82:2).

It seems likely that the OT understanding of righteousness was more concrete and less absolute than the typical thinking of most contemporary Western Christians. A more absolute way of understanding righteousness might lead one to think that a truly righteous person is sinless. While we do have references to absolute righteousness in the OT (e.g., Ps. 143:2; cf. Job 4:17; 25:4; Isa. 64:6–7), there are many more references to a righteousness grounded in particular or generalized situations (e.g., Pss. 32:11; 64:10). Another way of unpacking this conceptual difference is the helpful distinction between “ordinary” and “absolute” righteousness. Ordinary righteousness reflects the kind of righteousness that we intend when making comments such as “my wife is a righteous woman.” This means, taken in broad perspective, that her life is characterized predominantly by righteousness. This statement is not making a claim of sinlessness, absolute righteousness. The OT offers examples of comparative righteousness between people (e.g., Gen. 38:26; 1 Sam. 24:17; Jer. 3:11). Absolute righteousness is different from this. It is the extraordinary righteousness that we see in the person and work of God; he is righteous and without sin, totally holy in his dealings.

Noncanonical Jewish documents from the intertestamental period, while varying greatly in individual perspective, generally affirm OT views of human and divine righteousness. In these documents righteousness often is associated with mercy, goodness, justness, and concern for the poor and is contrasted with wickedness.

In Greco-Roman society, righteousness was one of the cardinal virtues and thus had an important influence in society. Greco-Roman righteousness did have some measure of abstractness as a kind of external norm, but this abstractness should not obscure the fact that righteousness often had a relational component in Greco-Roman literature and life. Righteous and unrighteous behaviors often were embedded in interpersonal relationships. Unrighteous deeds not only violated “transcendent” standards of righteousness, but also impacted humans.

New Testament

Ordinary human righteousness. Righteousness language is more rare in the Gospels than one might expect in light of OT and Jewish intertestamental usage. These references fit with the Jewish setting: righteousness is required of God’s people, and unrighteousness is to be avoided. Righteousness is proper conduct with respect to God or Torah (Matt. 21:32) in contrast to wickedness (Matt. 13:49). Righteousness could be conceived as one’s own (e.g., Luke 18:9) and has its reward (Matt. 10:41). While the specific terms related to righteousness are infrequent in the Gospels, the broader concept of conformity to God’s will is widely apparent in calls for repentance, personal moral uprightness, mercy, and concern for the marginalized. The NT Epistles continue these general strands of the concept. Righteousness is related to personal conduct (1 Thess. 2:10; 1 Tim. 6:11; 2 Tim. 2:22; 1 Pet. 2:24) and is contrasted with wickedness (2 Cor. 6:14); it is a matter of doing, not knowing (Rom. 2:13). An example of righteousness in doing is the kindness shown by the prostitute Rahab, who hid the Israelite spies (James 2:25).

The NT does signal some new dimensions related to righteousness. In the Sermon on the Mount (Matt. 5–7), Jesus extends the requirements of righteousness to conformity to his own teaching and directives, a shocking display of authority. In his mission to call sinners rather than the “righteous” (e.g., Mark 2:17), Jesus implicitly questions the righteousness of the “righteous.” In similar manner, personal righteousness in terms of a righteousness of one’s own is negative in the NT (Rom. 10:3; Phil. 3:6; cf. Luke 18:9).

Divine righteousness. The NT continues the OT theme of righteousness as it relates to God himself. God is righteous (John 17:25; Rom. 3:5; 9:14; Heb. 6:10; cf. Matt. 6:33). His judgments are righteous (Rom. 2:5), and his commands and laws are righteous (Rom. 7:12; 8:4). God is a righteous judge (2 Tim. 4:8). His saving activity is righteous; he does not compromise his own justice in justifying the ungodly (Rom. 3:24–26). The righteousness of God is contrasted with human unrighteousness and wickedness (Rom. 3:5; James 1:20). Since God reigns over creation in righteousness, human conduct should conform to that standard (e.g., Rom. 14:17). Jesus is also noted as righteous (Acts 3:14; 7:52; 22:14; 1 Pet. 3:18; 1 John 2:1, 29). He fulfilled righteousness in the absolute sense of demonstrating complete conformity to the nature and will of God (e.g., 1 Pet. 3:18). He also fulfilled God’s righteousness in the sense of his saving activity toward humans (e.g., 2 Pet. 1:1).

“The righteousness of God” and extra-ordinary human righteousness. There is a significant OT connection between God’s righteousness and his faithfulness in saving activity (e.g., Psalms; Isa. 40–66). Although there are glimpses of righteousness related to God’s saving activity outside of Paul’s Letter to the Romans (e.g., Matt. 5:10; 6:33), a technical phrase, “the righteousness of God,” is used in three important texts in Romans (1:17; 3:21–22 [2×]; 10:3 [2×]). In the gospel, “the righteousness of God” is revealed, where “righteousness of God” could mean his divine righteousness in some sense, righteousness from God (NIV), God’s saving activity as related to his righteousness in fulfilling his covenant faithfulness (e.g., Psalms), or some combination of these.

The righteousness of God is further discussed in Rom. 3:21: “the righteousness of God” has now been revealed apart from the Mosaic law, though the OT testifies about it (cf. Rom. 4 and Rom. 1:17; Gal. 3:11; Heb. 10:38). This righteousness of God is clarified in that it is by trust in Jesus Christ for all, both Jews and Gentiles. The “righteousness of God” may be distinguished from righteousness as a character quality of God (Rom. 3:25–26). In fact, it must be, for God’s righteousness as a character quality was revealed in the OT, whereas “the righteousness of God” is “apart from the [Mosaic] law” (3:21).

In Rom. 10:3 Paul comments that the Israelites are ignorant of “the righteousness of God”; they are seeking to establish their own righteousness because they are not submitting to “the righteousness of God.” The Israelites certainly knew of God’s righteousness in terms of his character, judgments, and expectations of his people. The lack of submission to “the righteousness of God” occurs in the context of the Jewish rejection of Jesus (e.g., 9:32–33; 10:9–13). And Jesus is the key to understanding “the righteousness of God” in the other texts also.

In Rom. 1:17 the righteousness of God is revealed in the gospel, which is the power of God for salvation to all who trust in Jesus (1:3–5, 16). The righteousness of God in 3:21–22 is related to trust in Jesus (3:22, 25–26), who as a sacrifice of atonement (3:25) enables the justification and redemption of sinners (3:24, 26). In Jesus we become the righteousness of God (2 Cor. 5:21). The righteousness of God, then, is God’s saving activity revealed and manifested in the person and work of the Lord Jesus Christ, whereby sinners are justified as both innocent and righteous in Christ.
