America's clergy have lost the confidence of millions, according to two recent surveys, and experts say pastors will have to confront some harsh truths to regain that trust. A poll released this week by Barna Group, an evangelical Christian polling firm, found that only 57% of Americans at least "somewhat agree" that a pastor is a trustworthy source of wisdom. The results drew on surveys conducted for "The Resilient Pastor," a new book by Barna senior fellow Glenn Packiam. Nearly a quarter of Americans, 24%, say they're "unsure" about the trustworthiness of pastors, with 1 in 5 Christians (21%) doubting the clergy. And only 21% of pastors say their neighbors "very much" see them in a trustworthy light.
