Between them they helped the ancient of days out of his crystal cell; it wasn't hard, for he was as light as paper, and he would have followed them anywhere, having no will of his own, and responding to simple kindness like a flower to the sun. But in the open air there was nothing to stop the wind from damaging him, and to their dismay his form began to loosen and dissolve. Only a few moments later he had vanished completely, and their last impression was of those eyes, blinking in wonder, and a sigh of the most profound and exhausted relief.
Then he was gone: a mystery dissolving in mystery.

At least when Christians decried the Da Vinci Code they did not have to make stuff up, just counter the stuff that was made up. Here we have Christians making stuff up to counter stuff that was not even present in the stuff that the author made up.
