In the reality where people can be raptured, what is logically incoherent about rapture causing slight discoloration of furniture? For me, if there’s difficulty in suspension of disbelief, it’s in the former part, not the latter.
As a licensed rapturologist I can verify that rapture events do leave stains on organic material. It’s the same miraculo-chemical process that burns Jesus’ face into the toast of true believers.
Why not? It’s like saying, “Witches don’t exist, but if they did, it’s ridiculous to think that they can make love potions.” I would even go so far as to say leaving “shadows” behind is a standard part of rapture lore.
I guess I’m just a lot less confident about how rapture physics works than some folks.
