author of Ephesians claims to be Paul in the opening address, itself identical to those of Second Corinthians and Colossians. There were no doubts in the late-second century church that Paul wrote the epistle: it was quoted authoritatively by church fathers, including Tertullian, Clement of Alexandria, and Irenaeus, among others. Ephesians may be an amended version of the letter to the Laodiceans in the Marcion canon (130) and the Muratorian fragment (before 180). The authenticity of this letter was first disputed by the Dutch Renaissance scholar Desiderius Erasmus, and in more recent times has drawn detailed criticism. The letter is made up of 50 sentences, 9 with over 50 words. The closest, Romans, has 3 out of 581 sentences of such length. E. J. Goodspeed, and C. L. Mitton argued the style was unlike Paul's other works. Many words in the letter are not in the "undisputed" epistles. A. van Roon argued the style is consistent with Paul, and thought the entire linguistic analysis dubious. In antiquity, the Greek Church Fathers, many of whom noticed the divergent Greek style of Hebrews, made no such comments about Ephesians. In this letter, the word ecclesia is used to refer theologically to the universal church rather than, as Paul typically employs it, to the local churches that he had founded. Also, the eschatological tone is more subdued than in other letters: the expectation of Christ's imminent return is unmentioned, while future generations are (3:21), as is a concern for social order. W. G. Kümmel argued that the theology is later than Paul. There is a close literary relationship between the Colossians and Ephesians. Over forty passages in Ephesians are expansions or variations of passages in Colossians. E. F. Scott argued that Paul used one letter as a model for the other, whereas others have considered Ephesians to be derivative of Colossians, edited and reworked by another. Donald Guthrie summarized the implications of this: "Advocates of non-Pauline authorship find it difficult to conceive that one mind could have produced two works possessing so remarkable a degree of similarity in theme and phraseology and yet differing in so many other respects, whereas advocates of Pauline authorship are equally emphatic that two minds could not have produced two such works with so much subtle interdependence blended with independence." Paul founded and built up the church in Ephesus; however, this letter does not appear to contain the
