This happened at the Harlem Book Festival and was aired on C-SPAN. I really recommend watching this. It was very insightful and I found myself nodding to a lot of it. It's mainly about whether the churches are afraid to interpret the Bible as they see fit if it goes against what the Evangelical churches have decreed, whether they have been caught up in the money game and how they could bring the young people and communities back into the congregations.
