Query: An author with a biased agenda

I am afraid that Ehrman is not an objective scholar. His self publication in the media, as a reactionary sceptic, in reaction to his former protestant (sola scriptura) fundamentalism means his work is suspect at best.Ehrman's origins as a naive fundamentalist were exploded at university and this embittered him to the point that he became a biblical iconoclast. This is not the foundation for sound scholarship. Ehrman's academic blood is poisoned. Any academic work Ehrman produces has a sceptical agenda which is either explicit or, in this case, implicit. My advice, leave well alone and use the work of the more balanced and objective.
