A new article addressing the nature of 2 Timothy as a piece of writing:
Krauter, Stefan. “Exilliteratur und die Gattung des Zweiten Timotheusbriefes.” Revue Biblique 129 (2022): 183–98.
Abstract: “2 Timothy is often referred to as a pseudepigraphic testament of Paul. A minority considers it an authentic paraenetic letter. The article criticizes both positions. There are rather superficial similarities between 2 Timothy and the Jewish testaments, and the setting of the letter is not a farewell situation. Theses about 2 Timothy as a conclusion to the Pastorals or the entire corpus Paulinum are poorly substantiated. The determination of 2 Timothy as a paraenetic letter is correct, but inaccurate. Conclusions regarding its authenticity cannot be drawn from it. By comparing 2 Timothy to exilic literature of the early imperial period, it is shown that it is possible to determine its specific character as a paraentic letter from captivity. This more precise determination makes it possible to integrate the moments of truth of both common research opinions.”
