"Mormon Stories 481: Jeremy Runnells Pt 2 - Jeremy Runnells Discusses the CES Letter in Detail," Youtube, June 21, 2014
Jeremy: It's not my information and I stand on the shoulders of giants, the Tanners. They're real...they're the real hipsters.
John: The Tanners?
Jeremy: Yeah, they knew a lot of this stuff in the '60s, and they're just now being vindicated. I heard about the Tanners, the "anti-Mormons", the God makers and all that stuff How can you not watch that interview with Sandra Tanner? She's just this nice grandma that knows a lot of stuff about Mormon history. I'm not a Christian. I don't really relate to the whole Christian stuff.
The stuff that they figured out and came out with - they were involved in a lot of stuff, that Mark Hofmann stuff, the Book of Abraham, and so it's really interesting. I stand on the shoulders of giants. What I did was I took their research, and their insights, and their works, and I put it in a way that worked best for me, that explained my train of thought in terms of why I no longer believed in the Church.
