Ephesians comprises volumes 34 and 34A of the Anchor Bible, a new book-by-book translation with introductions, notes and comments by individual scholars, each known for understanding contributions to biblical studies. Markus Barth, son of Karl Barth, held a New Testament chair at the University of Basel, Switzerland. Encompassing the body of Pauline theology, Ephesians has been called the crown of St. Paul's writing, yet both is authorship and addressees are the subject of continuing dispute. Through line-by-line examination of its vocabulary, its difficult style, its Qumran and Gnostic affinities, its parallies with distinctions from the undisputed Pauline corpus, its use the Old Testament, and its dialogue with orthodox and heretical Judaism, Markus Barth demonstrates that Paul was almost certainly the author. And after exploring previous explications of this hymnic and admonitory epistle in detail, he concludes that it was intended for Gentile Christians converted after Paul's visits to Ephesus.
