An interesting (though, IMO, underappreciated) article is that of:
John A. Tvedtnes,
“The Voice of an
Angel,” in Book of Mormon Authorship Revisited: The Evidence for Ancient
Origins, ed. Noel B. Reynolds (Provo, Utah: Foundation for Ancient Research
and Mormon Studies, 1997), 311-21
Let me quote the
conclusion to whet one’s appetite:
The nature of the accounts in Alma 29 and Alma 36-42 is that of an
eyewitness account of an event that so impressed the writer that he recalled it
with great emotion and clarity throughout his life.5 This is precisely what one
would expect from a man like Alma who had received an angelic visit such as the
one described in these chapters. We are indebted to Mormon for preserving the
discourses as Alma recorded them. (Ibid., 320-21)
