The July 25 issue of The Christian Century includes an interview with John Bell of the Iona Community and the Wild Goose Resource Group. Bell is not only eminently singable, he's also eminently quotable. This statement (p. 21) speaks to me:

If the church in the Northern hemisphere does not in the next ten years use songs that come from Asia, South America and Africa, it'll be deemed racist. It will be seen as a case of musical apartheid. Most Christians in the world are black and poor. They're not white and affluent. If that's the body of Christ of which we are a member, then we have to share the joy and the pain of fellow members.
