"Does this mean I can't play pinochle with my grandparents?"
"No, it doesn't mean that."
"It needs to say what it means," I said. It bothered me to agree with something if I didn't really know the rule maker's expectation.
Lists of rules and regulations abound among the Christian realm. Some are biblically based, others are not. It's a matter of man trying to control man's behavior instead of trusting God to do His part.
It's no different in the writing world. Some people who claim The Chronicles of Narnia as Christian classics, today want Christian writers to follow a list of do's and don'ts. Don't include magic, fantasy or elements of Science Fiction that cross...cross what? Man-made rules that say Do Not Enter? What about that wardrobe? Without the magic wardrobe no man would tread one foot in the magical realm known affectionately as Narnia.
In Speculative Fiction today, the rapidly changing Christian element is not a matter of conforming to the world's expectations (which would be following man-made rules). Instead, it's Christian authors following the imaginative path the Rule Maker lays out in a regenerated imagination.
See to it that no one takes you captive through philosophy and empty deception, according to the tradition of men, according to the elementary principles of the world, rather than according to Christ (Col. 2:8).
