Douglas Moo’s 1996 commentary on Romans quickly became a standard reference on Paul’s longest and most important letter. Pauline studies have blossomed in the last twenty years since the first edition was published. Many important monographs and commentaries on Romans have appeared as well as several important Pauline theologies. Many important responses to the New Perspective on Paul were published, such as the two volume Justification and Variegated Nomism (Baker, 2004). Some of these nuanced and expanded Sanders others sought a return to the traditional view of Paul and Judaism. N. T. Wright’s Justification generated various responses, culminating in Wrights massive Paul and the Faithfulness of God (Fortress, 2013) and a collection of essays in response to Wright, God and the Faithfulness of Paul (Fortress, 2017). Since these developments in Pauline Theology often center on key texts in the book of Romans, an update to Moo’s NICNT commentary is welcome.

The introduction to the letter in this second edition is more or less the same, several paragraphs from the first edition have been omitted or re-worked and there are a few references to recent work on audience and purpose. For example, Moo has added a reference to Michael Gorman and Richard Longenecker as he describes the participationist view of Romans 5-8 (22). He adds a line at the end of his discussion of salvation history as the theme of Romans making it clear that although it is an important conceptual scheme for Romans, “it cannot be called the theme of the letter,” citing Douglas Campbell 2005 work on Paul’s Gospel (25).

In the body of the commentary, Moo begins each section with a translation of the text with footnotes indicating textual issues. In the first edition the footnotes had their own numbering for each pericope, in the second edition the numbers continue the footnotes for a major section. For example, there are now 1291 footnotes for the section Romans 5:1-8:39.

After a brief introduction to the pericope, he proceeds verse-by-verse commenting on key features of the text. Since this is not a Greek text commentary, all Greek appears in transliteration in the body of the text, more nuanced details are covered in the footnotes. His comments on the text not simply exegetical since the book of Romans demands some theological reflection. For example, after dealing with the difficult phrase “faithfulness of Christ” in Romans 3:21, Moo deals with two potential objections his understanding of the phrase as an objective genitive, both from a theological perspective, specifically that his view may violate sola fide and solus Christus. This attention to both exegetical detail and theological importance is well balanced in the commentary.

Moo has updated the footnotes in the second edition to include works written in the last twenty years. A comparison of the Index of Authors quickly shows the inclusion of major commentaries by Jewett, Longenecker, Schreiner, Wright and others. These are not simply appended to existing footnotes; often Moo interacts with these recent works in the body of the commentary.

In addition, footnotes are streamlined by only including a shortened citation. Occasionally only a commentator’s name is used without page number. Readers should refer to the greatly expanded bibliography in the new edition for details. The bibliography for the first edition of the commentary was twenty-five pages, the second has expanded to 156 pages of abbreviations and bibliography.

Some excurses have been expanded, others are added. For example, in the first edition after Romans 6:1-14 there was an excursus entitled “Paul’s ‘With Christ’ Conception.” In the second edition the title is “’With Christ’ and ‘In Christ’” and more than two pages have been added commenting on the 131 occurrences of “in Christ” in the Pauline letters, with references to recent literature. The excursus following Romans 1:16-17 on the righteousness of God has been re-worked and expanded; it now includes a section on righteousness language and Isaiah 40-66 and the section on the phrase “righteousness of God” now includes much more detail from Isaiah. Moo has also updated the essay with references to recent works on the righteousness of God by Mark Seifrid, N. T. Wright, and others.

After the commentary on Romans 9-11, Moo has added about five pages on “Recent Assessments of Paul and Judaism.” This short essay deals with the so-called Radical New Perspective or “Paul within Judaism,” Messianic Judaism, and bi-covenantalism. In every case, these approaches to Paul try to take seriously Romans 9-11 and to avoid supersecessionism. Also new is an excursus on Paul’s reading of the Hebrew text of Genesis 15:16 following the commentary on Romans 4.

Conclusion. Moo’s commentary joins an already crowded field of recent major Romans commentaries, including Richard N. Longenecker’s recent New International Greek Text Commentary (Eerdmans 2016) and Thomas R. Schreiner’s second edition in the Baker Exegetical New Testament Commentary (Baker, 2018). I consider Moo’s 1996 commentary the “first of the shelf” (see my Top Five Romans Commentaries). This second edition is an upgrade to an already excellent commentary, one that should be on the shelf for anyone seriously studying the book of Romans.
