Even Steve admitted to it being a little heavy-handed, but John Coffey shared the same initials as another very important historical figure who also had powers to change water into wine and heal people's afflictions.
I think John has some form of “the touch” from the Dark Tower series, very similar to being able to shine but with its differences (Probably just a variation of the same thing). I definitely think Mother Abigail from The Stand definetly has Shining though.
I don’t think so, I can see your point but Coffey doesn’t really seem to be mentally challenged in the ways the roont children are, just uneducated. I’m only 1/3 into Wolves of the Calla so maybe you’re coming from something I haven’t learned yet.
