Being an SDA myself I took interest in the SDA Robert gentry being quoted in the creation book and Edwin Theile. Scholar says is perhaps the greatest chronologist of the 20th century in christendom.
My dad an SDA elder and most prominent lay preachers in the region nor I have any knowledge of these two individuals. It may be their books are written for a small range of members or they havent promoted there books sufficiently. Even some seemingly best sellers in the SDA community are failures from a publishing point of view and cant be equated to the JW method of selling their books where everyone is a best seller eg book study books.
I couldnt even find a quote from Robert Gentry in the Faith and Science conferences in Denver Colorado 2004 and Glacier View Colorado in 2003 where the SDA church is trying to come to terms with evolution v creation and people from both sides are presenting their papers and appealing for understanding on these issues.
Theile and Gentry are certainly not household names in the SDA community nor in the wider christendom.
