Could be, thought she's too generic to say for sure.

Something funny about early Christianity is that the rites we now all know (baptism, communion, theology, etc) were mysteries or secrets only the initiated/baptized knew about. This meant that while Christianity was "ouranic" in the sense that it worshiped a Sky Father and believed in bloodless sacrifice, from the pagan roman POV they all looked like shady, secretive worshipers of a mysterious resurrected deity who gathered around tombs and spoke about eating flesh and drinking blood all day, while also venerating the remains of their deceased leaders. It was also easy to believe because they didn't had, unlike us, access to the private correspondence and the writings of the early church leaders, which would've dispelled the "crazy witch cult" reputation.

Now, there was a bunch weird chthonic cults in the old Empire, of course, and some might have actually been involved in authentic gnarly rites. What made Christianity cross the treeshold of tolerance was not worshiping the Emperor on top of being a young tomb cult. The jews got away with it only because romans respected that their traditions were old, and in fact Julian used them to fuck the Christians over sometimes.

The kicker in all of this? When Christianity won against the other mystery cults and the corpse of old roman paganism, they started saying very similar stuff about the jews being secretive witches. It's a never-ending cycle, it seems.
