“All things are lawful to me, not all things are expedient. All things are lawful to me, all things edify not.”—I Corinthians 10:23
Philip K. Dick noted that one of the first places that the spirit of salvation tends to manifest is in the trash heap. Some trashy bit of fiction, a cheap bit of jewelry, a character in a TV show, becomes illumined all out of proportion to their material presence and speaks to us. It’s the sort of thing that superficially seems to justify all sorts of pop culture magic experimentation, but if placed in the context of the ghost-ridden fallen world, speaks against such efforts.
