It might seem hackneyed to have the bad guy vulnerable to Christian invocations - but why not?
The twist is that he's only vulnerable when it's read in a particular language or dialect. Either make him vulnerable to (say) the Lord's Prayer in Greek (or Latin) and have Concerta unable to come up with the idea of reciting it in an archaic tongue.. Or, have her try the same in Latin, or reciting from the AV when in fact he's vulnerable to modern day English.

Whichever you think more fun.
Just thought of this for some reason.
