Timothy

The First Epistle to Timothy is one of three letters in New Testament of the Bible often grouped together as the Pastoral Epistles. (The others are Second Timothy and Titus.) The letter, traditionally attributed to Saint Paul, consists mainly of counsels to his younger colleague and delegate Timothy regarding his ministry in Ephesus (1:3). These include instructions on the forms of worship and organization of the Church, the responsibilities resting on its several members, including episcopi (overseers or bishops) and diaconi ("deacons"); and secondly of exhortation to faithfulness in maintaining the truth amid surrounding errors (iv.iff), presented as a prophecy of erring teachers to come.
The genuineness of Pauline authorship was accepted by Church orthodoxy as early as c. 180 AD, as evidenced by the surviving testimony of Irenaeus and the author of the Muratorian fragment. Possible allusions are found in the letters from Clement of Rome to the Corinthians (c. 95), Ignatius of Antioch to the Ephesians (c. 110) and Polycarp to the Philippians (c. 130), though it is difficult to determine the nature of any such literary relationships. 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. Holmes argued that it is 'virtually certain or highly probable' that Polycarp used 1 and 2 Timothy
Late in the second century there are a number of quotations from all three Pastoral Epistles in Irenaeus' work Against Heresies. The Muratorian Canon (c. 170-180) lists the books of the NT and ascribes all three Pastoral Epistles to Paul. Eusebius (c. 330) calls it, along with the other thirteen canonical Pauline Epistles, "undisputed"[6], despite the fact that Eusebius wrote in the 300s with little to no knowledge of the complex social structures which line the books of the New Testament. Exceptions to this positive witness include Tatian,,a disciple of Justin Martyr turned heretic, as well as the Gnostic Basilides
Marcion, an orthodox Bishop later excommunicated for heresy, formed a Gnostic canon of Scripture c. 140 around ten of the canonical Pauline epistles, excluding 1-2 Timothy, Titus and Hebrews. The reasons for these exclusions are unknown, and so speculation abounds, including the hypotheses that they were not written until after Marcion's time, or that he knew of them, but regarded them as inauthentic. Proponents of Pauline authorship argue that he had theological grounds for rejecting the Pastorals, namely their teaching about the goodness of creation (cf. 1 Tim 4:1 ff.).The question is indeed curious whether Marcion knew these three letters and rejected them as Tertullian says, since in 1 Timothy 6:20 "false opposing arguments" are referred to, with the word for "opposing arguments" being "antithesis", the name of Marcion's work, and so whether it is a subtle hint of Marcion's heresy. However, the structure of the Church presupposed which is less developed than the one Ignatius presupposes (who wrote c.110), as well as the fact that not only is "antithesis" itself a Greek word which simply means "opposing arguments" but as it has been noted, the attack on the heretics is not central to the three letters
