Perhaps one of the most controversial (and therefore most written-upon) passages of First Timothy is 1Ti 2.12.
The blog Evangelical Textual Criticism today points to a recent article by Philip Payne, "1Ti 2.12 and the Use of ουδε to Combine Two Elements to Express a Single Idea". This is from New Testament Studies 54 (2008): 235-253.
Check out the article. I've not read it yet so don't have much more to report. I do note, however, that the function of αλλα (something I've recently written about) apparently plays some sort of role in Payne's discussion, though he looks to focus more on ουδε.
