I have to give this one star since Bart Ehrman is a bible scholar and historion (NOT a political figure). He is a self professed agnostic whose one of the more distinquished scholars of our time and certainly respectable as well. Since he's neither a believer or nonbeliever I consider his findings reliable since I won't have to worry about him having any theological axe to grind or any sort of agenda. His historical jesus books are the ones I like to read (even if he isn't a believer in his ressurrection and just thinks of Jesus as an apocalyptic prophet). However, I appreciate that he is at least honest , he doesn't break any academic rules when approaching the subject of Jesus.
P.S. the listing should be someone that changed his religious faith as an adult. However, Bart Ehrman is a good enough man/scholar to write about.
