If it depicted divinity sans Christianity, would you (generic “you”) be complaining that it depicted false gods? I’ve seen some complain mightily about the spiritual aspects of Lord Of The Rings.
Perhaps the story is better with no supernatural references, as opposed to improper ones.
I’d probably not complain about wider, obtuse ideas about gods or God. Just because I think that people as a species will always be able to realize that something smarter and more powerful than they are had a hand in their creation. That’s what’s absent from the book.
Where there is divinity, there is a spark of necessarily unreasonable hope. That is missing...
