We're talking about the "Gilbert and Sullivan" problem for dreaming up far-fetched symbolic meanings for narrated Gospel details. "If everybody's somebody, then no one's anybody." This week we see the "it's too easy" objection by considering this: If you can use "the sevenfold gift of the spirit plus the ten commandments, and then take the triangular number of that" as an unstated symbolic meaning of the 153 fish in John 21, you could dream up something just as "good" (that is, just as far-fetched and silly) if the number were something else.This is another way to see that using our creativity to come up with unstated symbolic meanings is a bad method.
