D.Moo has spent a long time writing this commentary and its shows. It is the first major commentary to engage with the New Perspective from a reformed perspective and that alone makes it a worthwhile commentary to own (regardless of what side of the debate you are on). Moo blends faithful scholarship & exegesis to tackle the book of Galatians and his conclusions are not easily dismissed. If you want a thorough commentary that is up-to-date in its scholarship this is first choice!
A very helpful commentary on a difficult letter of St Paul. It's good to have a refreshing Reformation emphasis on Justification by faith alone. The author explains the controversial passages clearly and fairly. An excellent commentary to go with Luther and Lightfoot
