if we took the bible literally (like some Christians believe), then what
would you have to believe?

let's add them up:

Matt: 3:11

"I indeed baptize you with water unto repentance: but he that cometh after
me is mightier than I, whose shoes I am not worthy to bear: he shall baptize
you with the Holy Ghost, and with fire":

fo asks: with "fire"?

So you're asking whether if you go potty and it flushed OK, but the next
guy with a "mightier" load clogs it up, does it take "fire" (i.e.
desoldering the old copper drains) to clear it?

Probably not - a snake should take care of it.
