Well, Piper is a Baptist, after all, so by definition he doesn’t have the same emphasis on “covenant” as do most other Reformed theologians… not to mention it isn’t that much of a stereotype to recognize that Baptists in general put a stronger emphasis on “saying the right prayer” in order to get to heaven than you find in the larger Reformed tradition (not that I’m claiming Piper would be one of those).
But that said, if you are correct that the only difference between traditional Reformed, Reformational theology, and that of the New Perspective on Paul is one of emphasis …
Then the NPP isn’t really or actually saying anything new, simply emphasizing different things than the Reformation or later Reformed theologians tend or tended to emphasize… and if so, then there is by definition no actual core conflict between the two, and thus there was nothing messed up at core in the Reformers actual understanding of justification of an individual being by grace through faith, rather they merely emphasized that aspect, perhaps wrongly, and failed to emphasize the larger covenantal ramifications other implications of justification and the larger Gospel?
But certainly this wouldn’t be particularly controversial. I haven’t read anything in detail by Wright or other proponents of the NPP, but from my vague recollection, they certainly seem to have been saying more than that the difference between their perspective and that of the traditional Reformed view was merely one of emphasis. It always seemed to me that Wright or other proponents of the NPP were claiming that the Reformers erred in their understanding of justification, rather than that they wrongly emphasized a certain aspect?
(Even so, the “emphasis” for individuals to repent, to be wary of the fact of a final judgment to heaven or hell, and to believe in Jesus in order to have eternal life doesn’t seem to be an emphasis that began during the Reformation… “Whoever believes in him is not condemned, but whoever does not believe stands condemned already because they have not believed in the name of God’s one and only Son.” “Today you will be with me in Paradise”… etc., etc., etc.)
Ah, copy. Not trying to be pedantic but I couldn’t make sense of the words.
That said, if there is any “focus” of justification on atonement, I’d submit the root cause may not be the Reformation or later Reformed theology… it seems that someone prior to the Reformation also occasionally combined justification and atonement in the same breath…
…are justified freely by his grace through the redemption that came by Christ Jesus. God presented Christ as a sacrifice of atonement…
…While we were still sinners, Christ died for us. Since we have now been justified by his blood…
