“‘Justification’ (and related words like ‘righteousness,’ all of which come from the same Greek root) has often been understood as a legal (judicial, forensic) concept. It is associated with the image of God as a judge rendering a ‘not guilty’ verdict to the guilty. However, although there is certainly a judicial dimension to justification…, it is now generally understood as a much more relational and especially covenental concept than previously recognized (cf. Rom. 5:1-11, where it is paired with ‘reconciliation’). To be justified is to be restored to right covenantal relations now, with certain hope of acquittal on the future day of judgement (Rom. 5:9-10; Gal. 5:5).
‘Faith’ is likewise a covenantal term that implies not merely intellectual assent, but faithfulness–a total commitment of the self from the heart that is more akin to loyalty, obedience, and devotion (as in ‘love of God’) than to ‘belief’ or even ‘trust’ (though each of these must still be understood to be part of faith). A growing number of scholars–approaching a consensus–believe Galatians 2:15-21, like Romans 3:21-26 and Philippians 3:2-11, speaks not only of our faith but of Christ’s faith, understood in this covenantal way as his faithfulness. Space does not permit an argument for this interpretation, but it is recognized in the NRSV margin and will be adopted as the basis for the commentary below. Specifically, it affects two verses…. The NRSV marginal translation (our interpretation) means that Paul understands Christ’s death as his faithfulness to God in giving himself on the cross “for me” (us–Paul speaks representatively), and that it, rather than our performance of the works of the Law, is the basis of our right relationship with God.” (Michael J. Gorman, Apostle of the Crucified Lord, p. 201).
