That question might well arise when interested persons hear of Steve Runge’s new project, the Lexham Discourse Handbook: Romans.
In the words of the author,
The project provides a close reading of the Greek, engaging it on its own terms. It analyzes how various discourse devices are used to highlight themes or organize the letter from the standpoint of discourse grammar. It is a commentary in many ways, but not in others, so I opted to call it a handbook.
I have, courtesy Steve, a sample PDF which describes his method and shows how it works in Romans 1:1ff. If you’d like to see it I’ll gladly email it, or you can just download it from Steve’s blog (once it’s posted).
Steve tells me
An inevitable question will be, “Can I get it in print?” I expect there will be a print version at some point as there was with the discourse grammar, but likely some months after the electronic version is released.
I read the sample and, as I told Steve, it left me wanting more. I think you may well feel the same.
