People ask me if I ever thought of writing a children's book. I say 'If I had a serious brain injury I might well write a children's book' but otherwise the idea of being conscious of who you're directing the story to is anathema to me because in my view fiction is freedom and any restraints on that are intolerable.
Anyone who really studies Catholicism deeply is aware of the mystical nature of our faith. Even references to Christ's mystical body has connections to that principle.
