I was looking for a gift to give to my philosophy teacher about the Orthodox Church. He is an atheist but enjoys learning about religion. What would be a good book for him?
You mean good for his soul? Really engaging to him on an intellectual and personal level?
If so, I would probably say
Lost Christianity, a book by Jacob Needleman, a professor of philosophy and comparative religion. He's an extremely prolific author and his prose is excellent. Here's a summary from his Web site:
...Lost Christianity is a profound reexamination of the essence of Christian thought and faith. Philosopher and bestselling author Jacob Needleman has sought out the ancient texts and modern practitioners of essential Christianity, whose message speaks directly to contemporary seekers.
