Strong on background information but sometimes that gets in the way of interpretation in my opinion. For example peace with God, in 5:1, doesn't mean with God. It means peace with one another because the Churches in Rome weren't at peace with one another. That's one example were Jewett misses the mark. Just to be fair Jewett does give a defense for this view that I'm not going into here. Still an important commentary and I'm very glad I have it.
