First, check out the blog written by my very good friend and brother in the extended Hahn family, Chris Cuddy. Chris, a seminarian, is one of the most amazing young intellectuals I have ever met.
Second, I urge you to click on over to Novum Testamentum Blog, a truly exceptional site run by Brendon Wason and Jason Bethel. This is really one of the cream of the crop of the academic sites out there. I read it almost every day but I have somehow failed to mention it here.
Third, I want to mention a site that I've been reading for some time now, but, somehow, I've failed to mention here: Irish-Catholic and Dangerous, a blog by Danny Garland, a graduate student at Franciscan University.
Fourth, head on over to Josh McManaway's A New Testament Student. Josh is in his third year at Southeastern College and is writing some very thoughtful posts.
Finally, I highly encourage you to take a look at Lumen Gentleman Apologetics, a Catholic site. At first glance this might appear to be just another apologetics website. Far from it! Jacob Michael is putting together some excellent materials over there, such as this interesting take on the footwashing in John 13, which he interprets in terms of sacramental ordination. Also see this article on the identity of Melchizedek. I'm not a particularly polemical person so I appreciate the kinds of articles Michael has been writing on this "apologetics" site.
Many more could be mentioned, especially among the biblioblogs--I'll be talking more about them soon...
