Once distinguished from Judaism, Christianity was no longer seen as simply a bizarre sect of an old and venerable religion; it was a "superstitio". Superstition had for the Romans a much more powerful and dangerous connotation than it does for much of the Western world today: to them, this term meant a set of religious practices that were not only different, but corrosive to society, "disturbing a man's mind in such a way that he is really going insane" and causing him to lose humanitas (humanity). The persecution of "superstitious" sects was hardly unheard-of in Roman history: an unnamed foreign cult was persecuted during a drought in 428 BC, some initiates of the Bacchic cult were executed when deemed out-of-hand in 186 BC, and measures were taken against the Celtic Druids during the early Principate.
