Stephen Nichols, an excellent and winsome historian, recently visited a Bethel African Methodist Episcopal Church in Lancaster (named after "Mother Bethel", the founding church for the first African American denomintation). He took his class and made a few observations over at Ref21. Here's his last question:

"And, if you're white--or as Bono once said "almost pink"--like I am and you never visited a predominantly African American church, what are you waiting for?"

A couple books by Nichols that you should read if you haven't:

The Reformation: How a Monk and a Mallet Changed the World

For Us and for Our Salvation: The Doctrine of Christ in the Early Church

Heaven on Earth: Capturing Jonathan Edwards' Vision of Living in Between
