The NPP teaches that the righteousness of Christ is not imputed (or credited) to believers. Therefore, the NPP denies forensic justification. I think this is the most serious problem with the NPP, because, in the words of one theologian, it “undercuts a truly ethical basis of atonement and inserts a controlling subjective element (i.e., covenant faithfulness).”
Additionally, the whole of NPP softens the harshness of God’s wrath towards sin and the problem that God’s wrath presents for man. Do NPP advocates have a better reading of Paul? Do NPP scholars have a better handle on the Biblical data on justification? Are NPP proponents reading Paul and the New Testament in a more accurate and faithful way than Luther, Calvin and the Reformers? Is imputed righteousness a biblical concept?
Over the next week, I am going to look briefly at a few passages in relation to these questions: Romans 3:21-26; 4:2-6 and 2 Corinthians 5:21.
