I wasn’t familiar with Nag Hammadi. That history actually gives GB a little cover.
I recognized right off that he was confusing Nag Hammadi with the DSS. That does not change the fact that it shows just how ignorant the LDS are when it comes to such things and that he is parroting LDS doctrine without having done research.
BTW, I first semester Bible student can tell you the difference between the NG and DSS, even at Liberty University.
