Introduction — Righteousness and Justice
The Greek term dikaiosynē (δικαιοσύνη), by which the New Testament designates "justice" or "righteousness," translates the Hebrew tsedaqah (צְדָקָה), a root that in the Hebrew Bible does not denote an abstract moral quality but a relationship: to be "in the right" means to stand in the correct position with respect to the covenant. The tsedaqah of the Hebrew Bible encompasses three inseparable dimensions — forensic (the divine declaration of righteousness), social (equitable redistribution within the community), and cultic (obedience to the mitzvot as a response to the covenant). The New Testament inherits this structure and repositions it christologically, yet without abolishing the practical dimension: the 16 commands of this page demonstrate that righteousness remains, for the disciple, a demanding halakhah.
Hunger and Thirst: Righteousness as Existential Orientation
The beatitude of Mt 5:6 — "blessed are those who hunger and thirst for righteousness" — is the programmatic point of departure. The verb πεινάω/διψάω (to hunger/thirst) describes a visceral orientation, not an intellectual preference. The LXX employs the same pair in Ps 107:5 to describe Israel in the wilderness: the disciple's hunger for righteousness is compared to the biological hunger of the wayfarer. The object of the thirst — dikaiosynē — is not a private sentiment of rectitude, but the covenantal order of God that finds its full realization in the kingdom (Mt 5:10: "blessed are those persecuted for righteousness, for theirs is the kingdom of heaven").
Mt 6:33 formulates the command in its imperative form: "seek first the kingdom of God and his righteousness." The verb ζητεῖτε is a present imperative — not a punctual action but a continuous orientation. The formula "first" (πρῶτον) establishes a hierarchy: the righteousness of God precedes every material concern, not because the latter are illegitimate, but because they find their proper order only within the project of the kingdom. Mishnah Avot 2:1 teaches: "be scrupulous in the fulfillment of every light precept as of every grave precept" — whoever hungers for righteousness accepts the cost of persecution for the gain of the kingdom.
The Righteousness of God Revealed in the Messiah
Rm 3:21-26 introduces the theologically densest category: dikaiosynē theou, "the righteousness of God." Paul distinguishes two planes: righteousness as a divine attribute (God is righteous) and righteousness as a power that God enacts in history. The latter "has been manifested" (πεφανέρωται, perfect passive) in the Messiah, independently of the Torah yet attested by the Torah and the Prophets. The Pauline paradox is that God is "just and the one who justifies" (δίκαιος καὶ δικαιῶν, Rm 3:26): the cross does not suspend the righteousness of God but manifests it, because the judgment owed to humanity falls upon the Messiah while the declaration of righteousness (dikaiōsis) is attributed to the believer.
The practical command arising from this theology is in Rm 6:13: "offer yourselves to God as those alive from the dead and your members as instruments of righteousness." The term ὅπλα (instruments/weapons) evokes the context of spiritual warfare, but the imperative is clear: dikaiosynē is not only a forensic declaration but a bodily orientation. The members of the disciple — hands, tongue, mind — become "instruments of righteousness" when they are surrendered to the service of God rather than to sin. Lv 19:35-36 roots this bodily dimension in the Torah: just weights and measures are not merely commercial prescriptions but an expression of the tsedaqah of YHWH himself ("I am the Lord your God").

Mt 5:20 poses the challenge: "if your righteousness does not surpass that of the
