Nature and Grace in Galatia

During a student presentation on Dunn’s article on the New Perspective on Paul, it struck me that there’s a nature/grace debate going on in Galatians and in the Judaizer conflict. Judaizers say that grace has come, but the “cultural” or “natural” (cf. Gal 2:16) form of covenant life remains the same. Grace doesn’t touch nature. Paul says the opposite; the coming of faith/grace means the transformation of nature/culture.
