Two Righteousnesses: Law and Faith, and the Universal Call to Salvation (Part 1)
5For Moses writes about the righteousness of the law, “The one who does them will live by them.”6But the righteousness which is of faith says this, “Don’t say in your heart, ‘Who will ascend into heaven?’(that is, to bring Christ down);7or, ‘Who will descend into the abyss?’ )”8But what does it say? “The word is near you, in your mouth and in your heart;”that is, the word of faith which we preach:9that if you will confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.10For with the heart one believes resulting in righteousness; and with the mouth confession is made resulting in salvation.11For the Scripture says, “Whoever believes in him will not be disappointed.”12For there is no distinction between Jew and Greek; for the same Lord is Lord of all, and is rich to all who call on him.
Romans 10:5–12 contrasts two paths to righteousness: the Law's demand for perfect obedience versus faith's accessibility through belief in Christ's resurrection and vocal confession. Paul argues that salvation comes through interior conviction combined with public witness, available equally to all people regardless of ethnic background.
Salvation is not a distant peak you must climb—it's a word already in your mouth and heart, waiting to be spoken.
Verse 10 — Chiastic Balance Verse 10 reverses the order: the heart believes unto righteousness; the mouth confesses unto salvation. This elegant chiasm (heart → mouth in v. 9; mouth → heart → mouth in v. 9–10) reinforces the inseparability of interior faith and exterior witness. Catholic tradition reads this not as a minimal requirement for a one-time act, but as describing the ongoing posture of the baptized Christian — one who is continuously conformed to Christ inwardly and who bears witness outwardly.
Verse 11 — Scripture Confirms: No Disappointment Paul anchors the promise in Isaiah 28:16 (the cornerstone text he already cited in Rom 9:33): "Whoever believes in him will not be disappointed." The Greek kataischynthēsetai ("be put to shame/disappointed") evokes the ancient honor-shame dynamic: those who trust in Christ will not find their trust exposed as misplaced. This is a promise of eschatological vindication.
Verse 12 — The Universal Lord The universalism Paul has been building toward throughout Romans (cf. 1:16; 3:22–23; 4:11–12) reaches a new apex: "there is no distinction between Jew and Greek." This echoes the "no distinction" of 3:22 (all have sinned) but now inverts it positively — the same universality of sin corresponds to a universality of salvation. "The same Lord is Lord of all" identifies Christ as the universal Kyrios, and his inexhaustible richness is available to "all who call on him." The phrase "call on" (Greek epikaleō) is a Septuagint term for prayer and worship directed to YHWH (Joel 2:32, quoted in v. 13). Paul is applying to Christ what the Hebrew Scriptures reserve for God alone.
Catholic tradition reads this passage as a foundational text on the relationship between faith, justification, and the sacramental life of the Church. The Council of Trent (Session VI, Decree on Justification, 1547) drew on verses 9–10 to affirm that justification involves both interior transformation and exterior confession — it is never purely private or invisible. Faith is the "beginning of human salvation, the foundation and root of all justification" (Trent, Ch. 8), but it is not faith alone: Trent insisted that charity and the other virtues accompany saving faith, and that baptism is the instrument by which justification is received and the word of faith is sealed.
The Catechism of the Catholic Church (§§ 432–433) takes the confession "Jesus is Lord" as the heart of Christian faith and connects it directly to the divine name: "The name 'Jesus'... contains the presence of God." The Lordship of Christ declared in verse 9 is thus no mere human title but a divine claim that the Church has always confessed in her liturgy — especially in the great doxologies of the Mass ("Lord God, heavenly King") and in the Kyrie.
St. Thomas Aquinas, in his Commentary on Romans (Lect. 3 on Ch. 10), identifies the two righteousnesses not as two opposed covenants but as two stages in the one divine economy: the Law prepared Israel by revealing the need for a Savior; faith in Christ fulfills what the Law pointed toward. This developmental reading safeguards both the goodness of the Old Covenant and the surpassing excellence of the New.
St. Augustine (On the Spirit and the Letter, Ch. 29–30) sees in verse 8 a key to his theology of grace: the word is near precisely because the Holy Spirit writes it on the heart (Jer 31:33), not on stone tablets. The nearness of the word is the nearness of prevenient grace.
The universalism of verse 12 grounds the Church's missionary mandate. Ad Gentes (Vatican II, 1965) quotes the universal Lordship of Christ as the theological basis for the Church's mission to all peoples: "For God has reconciled all things in Christ" (AG §3).
For contemporary Catholics, Romans 10:5–12 cuts against two opposite errors. The first is a kind of spiritual elitism — the assumption that salvation requires heroic feats of ascetic achievement or theological mastery, that God is essentially far away and accessible only to experts. Paul's response is startling in its simplicity: the word is near you, in your mouth, in your heart. This is an invitation to recover the confidence of ordinary faith — the faith of a parent who teaches a child to pray, of someone who goes to Confession after years away, of a Catholic who makes the Sign of the Cross before a meal in a restaurant. These are not trivial gestures; they are enactments of the confession "Jesus is Lord."
The second error is a possessive provincialism — the assumption that salvation belongs to one group, nation, or culture. Verse 12's declaration that "there is no distinction between Jew and Greek" challenges every form of Catholic insularity. The richness of Christ is inexhaustible and available to all who call upon him. This should animate both the New Evangelization and every Catholic's daily encounter with people of different backgrounds: the same Lord is their Lord too, even before they know it.
Commentary
Verse 5 — The Righteousness of the Law Paul opens by citing Leviticus 18:5: "The one who does them will live by them." This verse encapsulates what Paul elsewhere calls the principle of works-righteousness: life is conditioned on full, sustained obedience to the commandments. Paul is not dismissing the Law as evil — he has already called it "holy, just, and good" (Rom 7:12) — but he is identifying its structural logic: it demands performance and grants life only to those who perfectly fulfill it. The problem, developed throughout Romans 1–8, is that no fallen human being achieves that standard (Rom 3:10–12, 23). The Law thus functions, paradoxically, as both a revelation of God's will and a revelation of human inability. This first mode of righteousness, then, is real but inaccessible to sinners.
Verses 6–8 — The Righteousness of Faith Speaks Paul now does something strikingly bold: he personifies "the righteousness of faith" and puts Deuteronomy 30:12–14 in its mouth. In its original context, Moses is assuring Israel that the commandment he is giving them is not impossibly remote — it is not hidden in heaven or across the sea, but is near, in their mouths and hearts (Deut 30:11–14). Paul performs a profound typological re-reading: Moses was already pointing, beyond the letter of the Law, to the deeper proximity of a divine word that would be internalized.
Paul's parenthetical glosses are exegetically daring. "Who will ascend into heaven?" is glossed as "that is, to bring Christ down" — a reference to the Incarnation. No one need perform an impossible heavenly ascent, because God himself descended in the Son. "Who will descend into the abyss?" — likely an allusion to the realm of the dead (the Greek abyssos echoing the Hebrew Sheol) — is glossed as bringing Christ "up from the dead," a reference to the Resurrection. In this reading, Paul sees the two great Christian mysteries — Incarnation and Resurrection — already encoded in Deuteronomy's rhetoric of nearness. The "word" that is near is identified explicitly in verse 8 as "the word of faith which we preach" — the kerygma, the apostolic proclamation.
Verse 9 — The Content of the Confession Paul now specifies what this word of faith entails: confessing with the mouth that "Jesus is Lord" (Kyrios Iesous) and believing in the heart that God raised him from the dead. This is the earliest creedal formula in the New Testament. "Jesus is Lord" (cf. Phil 2:11; 1 Cor 12:3) was not merely a pious sentiment — in the Greco-Roman world, it was a claim with political and religious stakes, and in the Jewish context, Kyrios resonated with the divine name YHWH. The resurrection belief is equally essential: it is not a metaphor for spiritual renewal but a claim about an event in history that vindicates Jesus as the Son of God (Rom 1:4). Mouth and heart together suggest the full engagement of the person — external proclamation and internal conviction are both necessary. Neither alone suffices.
