Conditions Of My Parole is about the further expansion and influence of Christianity.
It takes place roughly between 200 AD to 500 AD, I think.
I Think the title "Conditions of my Parole" is a metaphor for the 10 Commandments, or the church's rules in general.
I don't know for a fact at all, but I'm guessing maybe the church would let law breakers out of jail if they converted to Christianity and became traveling recruiters.
