The other day Marcus told me that there are Christians gathering at Titus’ house at night - apparently these godless deviants are having incestuous orgies. What’s next, child sacrifice? Cannibalism? Caesar really needs to put them in their place before they get out of hand.
This is a cult of women and servants. They prey upon the unfortunate and promise rewards, but only after death.
Marginally increase the support to your client network such that no plebeian feels desperate enough to join them. Or, simply wait. The cult will die out like many others have.
