Expert opinion is, at the end of the day, still opinion. But why would you not want to know what experts have to say? When you make a dental appointment, do you want your dentist to be an expert or not? If you build a house, do you want a professional architect or your next-door neighbor to draw up the plans? One might be tempted to say that in the case of the historical Jesus it is different since, after all, we are just talking about history; experts have no more access to the past than anyone else. That, however, is simply not true. It may be the case that some of my students receive the bulk of their knowledge of the Middle Ages from Monty Python and the Holy Grail, but is that really the best place to turn? So too millions of people have acquired their “knowledge” about early Christianity—about Jesus, Mary Magdalene, the emperor Constantine, the Council of Nicaea—from Dan Brown, author of the aforementioned The Da Vinci Code. But at the end of the day, is that such a wise choice?
NOTE: This is how I feel about apologists and creationists and those who take their word above that of real experts. Why would you ignore the word of experts unless you simply don't want to have your views challenged?
