Romans 4:23: Justification by faith?
How does Romans 4:23 support the doctrine of justification by faith alone?

Text

“Now it was not written for Abraham alone that it was credited to him,” (Romans 4:23).


Immediate Context: Romans 4

Romans 4 is Paul’s sustained exposition of Genesis 15:6—“Abraham believed God, and it was credited to him as righteousness.” Verses 1-22 demonstrate that Abraham was justified before circumcision, before the Sinai law, and apart from meritorious works. Verse 23 functions as the hinge: what was said about Abraham is “not written for him alone,” but also “for us, to whom righteousness will be credited—those who believe in Him who raised Jesus our Lord from the dead” (vv. 23-24). Thus Paul universalizes the principle of justification by faith, identifying it as the normative, God-ordained means of salvation for every age.


Original Language and Grammar

1. Οὐκ ἐγράφη δι’ αὐτὸν μόνον (ouk egraphē di’ auton monon) — “It was not written for him alone.”

2. ὅτι ἐλογίσθη αὐτῷ (hoti elogisthē autō) — “that it was credited to him.”

The aorist passive verb ἐλογίσθη (“was credited”) is identical in Genesis 15:6 (LXX) and Romans 4:22-24, emphasizing a legal imputation rather than an infused moral quality. The dative αὐτῷ (“to him”) and subsequent dative ἡμῖν (“to us”) are parallel, showing an identical mode of reckoning for Abraham and for believers today.


Old Testament Precedent: Genesis 15:6

Abraham lived about 2,000 B.C., centuries before the Mosaic covenant, temple sacrifices, or ritual circumcision (Genesis 17 occurs at least 14 years later). Genesis 15:6 records God’s unilateral covenant promise, authenticated only by Abraham’s trust. Romans 4:23-24 proves that the Spirit intended Genesis 15:6 to stand permanently as a template: righteousness is credited on the sole basis of faith in God’s saving promise.


The Principle of Imputed Righteousness

Paul’s legal metaphor logizomai (“to credit, reckon”) is drawn from commercial bookkeeping. Righteousness is placed into the believer’s account while sin is debited to Christ (cf. 2 Corinthians 5:21). The forensic sense precludes synergistic cooperation—God justifies “the ungodly” (Romans 4:5). Romans 4:23 underscores that this crediting is not a one-off historical curiosity; it is God’s settled accounting method for all who believe.


Paul’s Rhetorical Strategy: From Particular to Universal

Jewish exegetical tradition viewed Scripture as perennially relevant (cf. 1 Corinthians 10:11). Paul applies this hermeneutic: Genesis 15:6 is “written” (γράφω) not merely as history but as normative doctrine. The apostle leverages the canonical echo to teach that faith in the God who raises the dead (Romans 4:17,24) unites every believer—Jew or Gentile—to the same saving righteousness.


Canonical Harmony: Sola Fide Across Scripture

Habakkuk 2:4—“the righteous will live by his faith.”

John 3:16—eternal life is promised to “whoever believes.”

Galatians 2:16—“a man is not justified by works of the law but by faith in Jesus Christ.”

Ephesians 2:8-9—salvation is “by grace … through faith … not by works.”

Romans 4:23 therefore coheres with the broader testimony that justification is by faith alone (sola fide), entirely apart from human merit.


Clarifying “Faith Alone” Versus Works

1. Logical Exclusivity: Faith and works are antithetical as grounds of justification (Romans 4:4-5).

2. Faith’s Instrumental Role: Faith is a receptive empty hand; its efficacy lies in its object—“Him who raised Jesus” (v. 24).

3. Subsequent Works: Romans 6-8 expects sanctification, but these works flow from, not toward, justification (cf. Ephesians 2:10). Verse 23 guarantees that the divine ledger is settled the moment faith occurs, before any ensuing obedience.


Historical and Patristic Witness

• Clement of Rome (c. A.D. 96) cites Abraham’s faith being “accounted … for righteousness” and calls it an example “for us” (1 Clem 31).

• Irenaeus (c. A.D. 180) asserts that God “justifies the uncircumcised through faith” (Against Heresies IV.5.5).

These early citations mirror Paul’s “not for him alone … but for us,” indicating that the Church uniformly read Genesis 15:6 as a paradigm of sola fide.


Addressing Common Objections (e.g., James 2:24)

James condemns a dead, non-operative faith; Paul targets meritorious works as a basis for righteousness. Romans 4:23 shows that righteousness is credited at the moment of genuine belief, while James 2:21-26 demonstrates that authentic justifying faith subsequently evidences itself in works (cf. “faith working through love,” Galatians 5:6). There is no contradiction: one text defines the root, the other describes the fruit.


Pastoral and Behavioral Implications

Behavioral science observes that performance-based acceptance breeds anxiety; unconditional acceptance produces gratitude-driven change. Romans 4:23 liberates the conscience: believers stand already credited with righteousness. From this secure identity flows psychological resilience, ethical motivation, and doxological living—fulfilling humanity’s chief end of glorifying God (Romans 11:36).


Conclusion

Romans 4:23 explicitly extends the forensic crediting of righteousness to every believer, establishing that justification derives from faith alone, apart from works, ethnic markers, or ritual observance. The verse seals Paul’s argument, harmonizes with the full canon, rests on robust manuscript evidence, and supplies an unshakable foundation for assurance, worship, and life transformation.
