On the book of James, Dan McCartney, now at Redeemer Theological Seminary in Dallas (formerly at Westminster), has written an accessible, theologically-alert, and exegetically sound commentary: James (Baker Exegetical Commentary on the New Testament)
. McCartney uses an economy of expression — so though the commentary is not quite as long as some today, there’s plenty of exegetical depth.
. Cautious, careful, thorough, and totally rooted in both a theological grip and careful attention to the Greek text.
