Each summer for the past several years I have spent some time witnessing to Mormons. This necessarily involves some apologetics, which is not a part I particularly relish. These days I am content being a teacher, not a debater. But I am still just as passionate for truth.
I was reflecting this evening that while there is abundant external corroboration for the authors of the Biblical books, especially the New Testament, being historical persons, there is absolutely no external evidence for the existence of any of the authors of the various books contained in the Book of Mormon. Mormons will counter that these “prophets” lived in the ancient Americas, not the Greco-Roman world, but that does not eliminate the problem that, unlike the Scriptures of the Old and New Testaments, there is no documentation anywhere outside the pages of the Book of Mormon that the figures contained in it (and the purported authors of its various books), as well as the church and civilization in which they supposedly lived, ever existed.
In contrast, the writers of the New Testament were known by and attested to by numerous witnesses.
