Craig Blomberg reviews the new Pillar New Testament Commentary on II Peter and Jude, by Peter Davids. I just got my copy and haven't had time to look at it much, but I'm looking forward to spending a little time in it when we study II Peter in our congregation in August and September.
From what Blomberg says, there's a lot to look forward to. I tend to agree with the few criticisms he offers. I don't know why you would need to think of Jude seeing a writing as canonical for him to quote it, and I'm certainly with Blomberg on the eternal security point. But I don't expect that sort of thing to be the norm.
I should note that, while Blomberg says at the bottom of his review that Davids gets his asterisk for "top pick among detailed but not overly technical commentaries on the English text of these two little epistles", a quick glance at the page he's referring to shows that it doesn't occupy that position alone. Thomas Schreiner's NAC on both epistles to Peter and Jude is still asterisked. I've spent some time in Schreiner's commentary, mostly on I Peter, and it's absolutely excellent. His work on the other two epistles will no doubt be equally good.
