As already mentioned on Stephen Carlson’s blog, there’s an article in JSNT from last December that is interesting and exceptional. A graduate student at the Johns Hopkins University in Classics has written on the Greco-Roman usage of the word παρακλητος and how that sheds light on the New Testament’s use of the word. If you want to read it, here’s the citation: Lochlan Shelfer, “The Legal Precision of the Term ‘παρακλητος’,” JSNT 32 (2009): 131-150.
This article is an inspiration as it’s one of the reasons I’m applying to Classics programs to do graduate work. I think a lot of interesting light can be shed on the NT by Classics.
