"Sweeping statements about world views in first-century Judaism are precarious."
So in the interview (video) posted earlier Wright dismisses Piper rather flippantly. I am just now reading the chapter where Piper is delineating in a very nuanced and articulate manner, the dangers of using extra-biblical sources that are much less studied to then interpret Scripture itself.
He is absolutely not dismissing the idea of attempting to understand historical context and world views of the day, but is highlighting the dangers of putting these sources on the same, if not more important footing that Scripture itself.
