In this week's Review of Biblical Literature, Raymond F. Collins reviews Alfons Weiser's Der zweite Brief an Timotheus, which is part of the EKK (Evangelisch-Katholischer Kommentar zum Neuen Testament) commentary series.
Since I'm not able to read German, I'm grateful for the review. Sounds like there is decent interaction with patristic literature (yay!), though it also sounds like Weiser approaches the text as a pseudepigraphon -- in both sender and receiver.
