Here's a link to a very important article in Christianity Today by Edward Gilbreath entitled, Exit Interviews:
Why blacks are leaving evangelical ministries. It is adapted from Gilbreath's book, Reconciliation Blues: A Black Evangelical's Inside View of White Christianity. Several people have pointed me toward this book this week so I just ordered it. I also just discovered Ed Gilbreath's Blog thanks to Rodolpho Carrasco at Urban Onramps.
