Biblical Examples of Justification by Faith Alone in Scripture
Paul's letter to the Romans provides the most concentrated articulation of justification by faith. In Romans 3:20, the apostle declares that "by works of the law no one will be justified," establishing the negative premise [5]. He then unfolds the positive doctrine: "the righteousness of God is revealed from faith to faith; even as it has been written, 'But the just shall live by faith'" [3]. This quotation from Habakkuk 2:4 anchors the doctrine in the prophetic witness. Romans 4 extends the argument by appealing to Abraham, who "believed God, and it was counted to him as righteousness" before circumcision or the Mosaic law existed [7].
Galatians 2:16 offers a parallel formulation: "a man is not justified by works of the law, but by faith in Jesus Christ" [2]. The verse's threefold repetition—"not by works," "by faith in Christ," "by works of the law no one will be justified"—underscores the exclusivity of faith as the instrument of justification. Adam Clarke notes that "neither the works of the Jewish law, nor of any other law, could justify any man," and that justification by faith "is as reasonable as it is Scriptural and necessary" [6].
The forensic nature of justification is central to the Reformed understanding. Easton's Bible Dictionary defines it as "the judicial act of God, by which he pardons all the sins of those who believe in Christ, and accounts, accepts, and treats them as righteous in the eye of the law" [1]. This is not a relaxation of the law but a declaration that its demands are satisfied in Christ. John Gill emphasizes that the moving cause is "the free love and favour of God, as it is in his heart" [8], while Jamieson-Fausset-Brown summarizes Romans 4:16 as showing that "justification is by faith, in order that its purely gracious character may be seen" [7].
James 2:24, however, introduces a tension: "You see then that by works, a man is justified, and not only by faith" [4]. This verse has generated centuries of debate. Protestant interpreters typically distinguish between justification before God (by faith alone) and vindication before others (demonstrated by works), or between initial justification and its evidential outworking. Catholic theology, articulated at Trent, rejects the formula "faith alone" and insists on faith formed by love [9]. Eastern Orthodox tradition, reflected in Chrysostom's commentary on Galatians, affirms that "none other than believers have a share in Abraham's blessing" [10], yet integrates justification within a broader framework of theosis and synergy with divine grace.

As regards its nature, it is the judicial act of God, by which he pardons all the sins of those who believe in Christ, and accounts, accepts, and treats them as righteous in the eye of the law, i.e., as conformed to all its demands. In addition to the pardon (q.v.) of sin, justification declares that all the claims of the law are satisfied in respect of the justified. It is the act of a judge and not of a sovereign. The law is not relaxed or set aside, but is declared to be fulfilled in the strictest sense; an”

And see on Act 13:38 (note) and Act 13:39 (note), in which places the subject of this verse is largely discussed. Neither the works of the Jewish law, nor of any other law, could justify any man; and if justification or pardon could not have been attained in some other way, the world must have perished.
