That is an interesting video Phil, and perhaps I should rethink maybe recommending the book to a baby Christian, but a couple things that the anti-shack dude says that I disagree with are, 1. God the Father has appeared in the physical, or who did Moses see on mount Sinai, and who did Jacob wrestle with? 2. Jesus said 'who has seen Me has seen the Father.' that scripture to me makes Them equal and makes Them one. 3. the book definitively declares that God is not a woman or a man, so it does not promote Goddess worship. 4. A graven image is carved, etched, or sculpted by definition.
I have not been to seminary and I am not theologically educated, but I do have a sense of who God is, and what He finds as detestable and abominable from my reading of the scriptures and my relationship with the Spirit. I am not in spiritual authority over anyone, but as a layperson and a self proclaimed Christian man, I still do not see any harm in the Shack. It was a fun, emotional read, that does not try to alter the immensity of the Father, or the salvation of Jesus. I am not saying that it made me think any differently about God, but it did make me feel something for the characters in the book, which just so happened to be God. Our God is bigger than the Shack and in our futile attempts to control our theology perhaps a book of fiction could suspend all reasoning and cause us to fear, but I worship the Creator of the universe, and there is no little work of fiction going to tear Him down.
One more thing about the video that bothered me for some reason....the sign in the background read, 'What should Christians believe?' Who are we as fallible human beings to determine what Christians should believe? It sounds once removed from the inquisition to me. We have no right to tell anyone what they should believe....that is between them and their God, and we should stay out of it. We should minister and confess Jesus with love and passion, but we should never tell anybody what they should believe. Who are we? The Nazis?
