Anastasios beat me to this, but my thoughts are actually more for PDL
Have you read More than a Carpenter? Have you read the Purpose Driven Life?
Yes and yes.
MTAC is better than ETDAV, I admit...my problem with MTAC is mostly methodology, as he does come to some good conculsions.
PDL is quite vague. Starts off all right, with things like, "God has a plan for your life" and "God knows all the hairs on your head," but moves on to things like "What Makes God Smile?" and "Becoming Best Friends with God" -- making God seem like a weepy, sentimental pal rather than a King, Lord and Father -- and finally dealing out phrases like "God doesn't care how you worship, just so long as you *feel* Him" and "Jesus said our love for each other -- not our doctrinal beliefs -- is the greatest witness to the world." So, to quote the Beatles, All You Need is Love...and can't we all just put that pesky doctrine to the side and get along?
There are some good things in those books, but nothing is said in there that isn't said better or more completely in Orthodox sources. I guess my question would be this: why are you willingly exposing yourself (over and over, it sounds like) to these ideas that are just plain wrong, much less lauding them?
