According to terminology promolgated by Mark Driscoll and Ed Stetzer, Rob Bell has been identified as part of the Revisionist stream of the Emerging Church movement:
Revisionists are theologically liberal, and openly question whether evangelical doctrine is appropriate for the postmodern world. They look to leaders such as Brian McLaren, Rob Bell and Doug Pagitt. - wikipedia
According to Marcia Ford, in her article The Emerging Church: Ancient Faith for a Postmodern World:
So where can you find examples of the emerging church? Some postmodern-friendly churches have sprung from an intentional and interdenominational effort, such as Brian McLaren’s Cedar Ridge Community Church near Washington, D.C. Pretty much everyone in the emerging church recognizes McLaren as the movement’s elder statesman; his books, with titles like A New Kind of Christian and Adventures in Missing the Point (the latter with Tony Campolo), have helped define the emerging church.
Sometimes, the name of a particular church is a dead giveaway that it’s part of the movement, such as Scum of the Earth in Denver. Little question that it’s not, say, a Southern Baptist congregation. Many, like Solomon’s Porch in Minneapolis, which meets in a living room setting in an industrial building, see themselves as an experimental community. Still others aren’t really churches but ministries affiliated with traditional congregations, like The Crucible, a postmodern outreach of the huge Belmont Church in Nashville. Vintage Faith in Santa Cruz, California, Apex in Las Vegas, and Holy Joe’s in London are but a few others.
