Ben Witherington III, Is There a Doctor in the House? An Insider’s Story and Advice on Becoming a Bible Scholar (Grand Rapids: Zondervan, 2011), 83–84:

[excerpt from ch. 7: “The Write Stuff: The Ability to Research and Write”]

Unfortunately, we live in a culture of “experts” where expertise is revered; sadly, people’s egos get bound up in the desire to be a “world’s leading authority in X.” The expert too often feels it is enough to do pure research. He has no need to distill things for the masses; that’s beneath his dignity and pay scale. It is enough to live in one’s head and to talk only to other equally heady folk in the same field.

Whatever the merits of this approach to research in other fields, a Christian who is a Bible teacher or scholar should never take such an approach. Never! Research by a Christian is never done just for its own sake, or even just to advance knowledge in a given field. It is done in service to the Lord and to his church. I must confess I am sometimes baffled by some Christian NT scholars who are perfectly content to just talk to small circles of like-minded experts without any sense of responsibility to share their knowledge with a broader audience—indeed with the church.
