Query: What on earth is Rick Warren teaching?

The Purpose Driven Life is a sad reflection of the current state of American Christianity. It has little in common with traditional Protestantism of either the mainline or evangelical variety.This is light reading. Basically it is a self-help book that uses Christian vocabulary to communicate a 40-day program of personal self-improvement. At best it is harmless. At worst people may mistake it for true Christianity.If you must read this book, then at least balance it with a thoughtful critique, such as "More Than a Purpose" by Marshall Davis or "Reinventing Christianity" by Bob DeWaay.
