I recently came across this informative blog post defending the scholarship of Dr. Kerry Muhlestein, a Latter-day Saint Egyptologist who has commented much on the Book of Abraham and the authenticity thereof:
Reverend Spalding Strikes Again: A Response to Internet Criticism of Kerry Muhlestein’s Book of Abraham Videos
The ignorance of one Egyptologist on the issue of the Book of Abraham, Kara Cooney, is exposed, too, showing that simply because one has a PhD does not mean that they are necessarily informed about all matters in their particular field.
