Roger Oakland’s book (http://www.lighthousetrails.com/mm5/merchant.mvc?Screen=PROD&Store_Code=LTP&Product_Code=FA) is a great Biblical examination of the dangers of this cancer - another progression in the man-centered theology of Rome and Robert Schuller.
The theology of the Emergent “Movement” is New Agey Neo-Orthodoxy. According to it’s leaders (such as Erwin McManus, Brian McClaren, Rob Bell, Tony Jones, and Leonard Sweet) people help God “create” or “dream”. There teaching focuses on whatever makes us “feel” close to God. They do not teach the Gospel once and for all delivered to the Saints. They teach a form of Universalism and they mock the traditional Christian Church. They also question the Word of God.
Two great articles I have found on this heresy are:

by Bob Deway, who has spent the last couple years studying this movement.
and
“Rethinking Robert Schuller”
