The Epistles to the Colossians, to Philemon, and to the Ephesians (NICNT)
This work by F. F. Bruce is scholarly but readable. He begins with an introduction which covers the origins and authorship of Colossians, Philemon and Ephesians with particular focus on the geography of Asia Minor. He also discusses the Jewish community and the theological issues brought out in these books. According to Bruce, there are important reasons for linking Colossians, Philemon, and Ephesians together in one work. This is a section by section commentary on the three books, drawing out the important theological issues.
