The most recent issue of Journal for the Study of Paul and His Letters contains presentations on the Pastorals from a specialist conference held in Leuven in November 2018. The theme of the conference was “The Pastoral Epistles: Common Themes, Individual Compositions?” (program).
The JSPL issue contains an editor’s introduction, and another introduction to the special issue. An opening essay by Jermo van Nes sets the stage, followed by four sets of essays and responses, and “concluding reflections” by editor Stanley Porter. You can view the contents here, and I’ve compiled the abstracts here.
