Lee Irons gives a
preview of his forthcoming dissertation at Fuller under Donald Hagner. In short, it "will be a critique of the Hebraic/relational interpretation of Paul’s righteousness terminology from [Hermann] Cremer to the NPP [New Perspective(s) on Paul], with a special focus on the underlying lexical semantics of the question." I've earlier expressed my appreciation for Irons's exegetical and biblical-theological work, so I expect that this will be quite good.
