I recently watched an interview Fox conducted of Reza Aslan, who wrote a book called "Zealot: The Life and Times of Jesus of Nazareth," and the interviewer was obsessed with why Aslan, a Muslim, decided to write a book about Jesus. Aslan essentially spends the entire interview explaining what a scholar and a PhD is, along with what an academic work is.
To me, the answer seems obvious, but do you think that an academic can write about a person such as Jesus without being influenced by their personal religious background?
The video is really worth watching, especially the part at 9:10. Absolutely hilarious.
If you're interested in nuance, can an academic career like Aslan's overcome any potential personal influences?
