Charles Sullivan has written a chapter of his forthcoming book in which he goes through all the works of Origen and looks at what is said about the gift of tongues. The chapter is here. It can only be read online, tho, and not downloaded. I’ve skimmed it, as I don’t read stuff online all that well, but it contains some interesting ideas.
Tell Dr. Sullivan that the file can be downloaded so.
I think he’s changed it now.
