Author Frank Viola has written numerous books on radical church reform. You can find them all on the Reimagining Church site.

Here are the titles (excerpt from the site):

“In January 2008, Pagan Christianity by Frank Viola and George Barna rocked the Christian world. Yet it was only the first half of the argument. It was never meant to be a stand-alone book. In August 2008, Reimagining Church by Frank Viola was released. It presents the second half of the argument. Both books can be likened unto a puzzle. Pagan Christianity is the deconstructive side of the argument; Reimagining Church is the constructive side. Both books go together, forming a compelling and insightful vision of the church after God’s own heart. In March of 2009, the CBA bestseller From Eternity to Here by Frank Viola released. This book gives the big sweeping epic unveiling God’s grand mission in the earth. Some regard it as Frank’s magnum opus. A tour de force in missional theology. In September of 2009, Frank Viola’s practical guide to body life entitled Finding Organic Church made its debut (#12 on Completing the “ReChurch Library” is The Untold Story of the New Testament Church by Frank Viola. This book has been hailed as a masterful work in narrative ecclesiology and one of the most helpful New Testament guides in print. Jesus Manifesto by Leonard Sweet and Frank Viola released June 2010, reaching #6 on Amazon. This book is the hub that ties all the other volumes together.
