I read a comic once, long since given away, where Superman fought someone who was powered by prayer, without using force.
I'm hazy on the details, and there wasn't much to the story besides the 'powered by prayer' conceit.
I read it some ~7-8 years ago, and it was current at the time because it was part of a Sci-Fi Stack Exchange comic books giveaway (sadly discontinued).
I would like to be able to reference that issue when discussing how Superman's superlative abilities reduce his problems down to moral problems, but I've long since forgotten the series and issue number.
When did he fight a human who was powered by prayer?
