The First Epistle to Timothy is one of three letters in the New Testament of the Bible often grouped together as the pastoral epistles, along with Second Timothy and Titus. The letter, traditionally attributed to the Apostle Paul, consists mainly of counsels to his younger colleague and delegate Timothy regarding his ministry in Ephesus (1:3). These counsels include instructions on the organization of the Church and the responsibilities resting on certain groups of leaders therein as well as exhortations to faithfulness in maintaining the truth amid surrounding errors. Most modern scholars consider the pastoral epistles to have been written after Paul's death, although "a small and declining number of scholars still argue for Pauline authorship". Authorship of the Pauline epistles The authorship of First Timothy was traditionally attributed to the Apostle Paul, although in pre-Nicene Christianity this attribution was open to dispute. He is named as the author of the letter in the text (1:1). Nineteenth- and twentieth-century scholarship questioned the authenticity of the letter, with many scholars suggesting that First Timothy, along with Second Timothy and Titus, are not the work of Paul, but to an unidentified Christian writing some time in the late-first to mid-second centuries. Most scholars now affirm this view. As evidence for this perspective, they put forward that the pastoral epistles contain 306 words that Paul does not use in his unquestioned letters, that their style of writing is different from that of his unquestioned letters, that they reflect conditions and a church organization not current in Paul's day, and that they do not appear in early lists of his canonical works. Modern scholars who support Pauline authorship nevertheless stress their importance regarding the question of authenticity: I. H. Marshall and P. H. Towner wrote that "the key witness is Polycarp, where there is a high probability that 1 and 2 Tim were known to him". Similarly M. W.
