Caleb Miller on expressing uncertainty in the pulpit:

A consistent practice of avoidance, or refusal to admit concerns publicly, especially from the pulpit, gives the impression in the long run that doubt and uncertainty are things to be shamed and ignored, perhaps even feared, rather than patiently and pastorally addressed out in the open. If doubt itself becomes something to be feared, it becomes nearly impossible to tackle a problem authentically. On the other hand, a consistent practice of acknowledging any and all uncertainties, rehearsing each and every last unknown, especially from the pulpit, can lead to its own crippling disaster. If doubt is something idealized and venerated, a near-weekly occurrence and constant refrain demonstrating “authenticity,” telling our congregation so regularly that we actually nurse private doubts about the reliability of the biblical testimony, they will invariably begin to follow our lead. They will begin to lose confidence in the Scriptures, in us, or both.

Good observations. The core problem is that both of these approaches undermine the gospel. I look forward to reading more of his thoughts in forthcoming articles.
