The significant fact about the 'testament' genre was not in its markers but in its nature; it is argued that a piece of 'testament' literature is meant to "be a completely transparent fiction".
The oldest manuscripts containing some or all of the text of this book include: According to the letter, Paul urges Timothy not to have a "spirit of timidity" and not to "be ashamed to testify about our Lord" (1:7–8).
He was anticipating that "the time of his departure was at hand" (4:6), and he exhorts his "son Timothy" to all diligence and steadfastness in the face of false teachings, with advice about combating them with reference to the teachings of the past, and to patience under persecution (1:6–15), and to a faithful discharge of all the duties of his office (4:1–5), with all the solemnity of one who was about to appear before the Judge of the quick and the dead.
[14] Based on the traditional view that 2 Timothy was Paul's final epistle, chapter 4 talks (v. 10) about how Demas, formerly considered a "fellow worker", had deserted him for Thessalonica, "having loved this present world".
Chapter 4 also features the only biblical mention of Linus (v. 21), who in Catholic tradition is listed as Peter's immediate successor as Bishop of Rome.
[16] 2 Timothy 2:14-16 contains a number of commands addressed to Paul's co-worker (in the second person) about how one to teach or relate to those in disputes pertaining heresy.
