Apparently Purpose Driven nation is ratcheting up the rhetoric. At Slice of Laodicea Ingrid Schlueter points us to:

FBNS News Service report[ing] the following.

Transitioning: Leading Your Church through Change, a book by Dan Southerland that is highly recommended by Rick Warren, calls those who oppose the Purpose Driven philosophy “leaders from hell.” Southerland is “the leading expert on implementing the Purpose Driven paradigm in existing churches” (Church Transitions web site), and
Warren sells his book…

Pastor Bruce C. Kalish, who interviewed Southerland, brings to our attention that Southerland’s church, "Flamingo Road is heir to the Purpose Driven Strategy of Rick Warren’s Saddleback Community Church." And Zondervan, owned by Rupert Murdoch–the man Rick Warren claims to "pastor"–further informs us that Warren calls Southerland’s book:

"One of the most exciting and encouraging examples of transitioning from being program driven to purpose driven." From the foreword by Rick Warren, Author of The Purpose-Driven® Church
