There were a number of papers on the Pastorals at SBL this year including a full session of the Disputed Paulines study group being devoted to them.
The best paper on the Pastorals which I heard came from Jens Herzer of Leipzig. His paper was titled, “Language and Ideas of the Pastoral Epistles in Light of the Papyri.” Herzer, while not affirming Pauline authorship, has a positive view of these letters and presented solid work on the papyri. He argued for maintaining the individuality of the three letters (rather than simply lumping them together, as is too common), supported the idea of 1 Timothy as mandata principis, and made several other suggestions. Herzer seems to be working on a larger project on the Pastorals, so I will be watching for more from him.
