ends with Philemon;" "Papyrus 46, dated about 200, that follows the order that became established except for reversing Ephesians and Galatians;" "[T]he letters to seven churches, treating those to the same church as one letter and basing the order on length, so that Corinthians is first and Colossians (perhaps including Philemon) is last." Beginning in the early 19th century, many German biblical scholars began to question the traditional attribution of these letters to Paul. The vocabulary and phraseology used in the Pastorals is often at variance with that of the other epistles. Over 1/3 of the vocabulary is not used anywhere else in the Pauline epistles, and over 1/5 is not used anywhere else in the New Testament, while 2/3 of the non-Pauline vocabulary is used by 2nd-century Christian writers. For this reason, and because of a claimed precedence of 1 Clement, some scholars have associated these works with later 2nd-century Christian writings. The precedence of 1 Clement was challenged by R. Falconer, while L. T. Johnson challenged the linguistic analysis as based on the arbitrary grouping of the three epistles together: he argued that this obscures the alleged similarities between 1 Timothy and 1 Corinthians, between Titus and the other travel letters, and between 2 Timothy and Philippians. Norman Perrin argued that Paul's travels to Crete (Titus 1:5-6), again to Ephesus (1 Tim 1:3), Nicopolis (Titus 3:12), and Troas (2 Tim 1:15, 4:13) cannot be fit into any reconstruction of Paul's life or works as determined from the other epistles or from Acts. In this he was preceded by several scholars who rejected Pauline authorship. Robinson argued against this analysis, while others have debated whether this should be grounds for rejection of Pauline authorship, as Acts concludes while Paul is still alive. Harnack, Lightfoot and other scholars have suggested hypothetical scenarios that would have these epistles written near the end of Paul's life without contradicting biographical information in the other epistles or Acts. Scholars arguing for the authenticity of the pastorals posit a "second career" of Paul to explain the occasion for the visits mentioned in these letters, though contemporary scholars generally consider the "second career" of Paul to be a creation of later Christian communities. Other reasons for a 2nd-century date have been argued. The Pastoral Epistles lay out church organisation concerning the character and requirements for bishops, elders, deacons, and widows. Some scholars have claimed that these
