Zondervan's Listening to the Beliefs of Emerging Churches is due out soon. Edited by Robert Webber, it contains essays (and responses) by Mark Driscoll ("The Emerging Church and Biblicist Theology"), John Burke ("The Emerging Church and Incarnational Theology"), Dan Kimball ("The Emerging Church and Missional Theology"), Doug Pagitt ("The Emerging Church and Embodied Theology"), and Karen Ward ("The Emerging Church and Communal Theology").
You can see the table of contents, plus a portion of Driscoll's essay, in this PDF.
