They have a "non-negotiable commitment to Africa".
I understand that people with simplistic views can misunderstand what that means, but there has to be a really effective way to explain it.
For example, I've looked at their website, clicked on all the options, and from what I can tell, it simply means that they contribute to aid for Africa and they teach African heritage classes to the youth in the community.  Let me add, they don't teach the African heritage classes to all the youth in the church, they're like optional after school type classes.
I find his church to be fairly spiritually uplifting, regardless of denomination or the ethnic tone.
