Perhaps, have no idea myself. Do you have any data on that?
Still, I would assume it refers to serious scholars and not those buying into the fairy tales.
Most medical doctors are likely also nominally Christian, but we mostly assume they do proper medicine even so and do not resort to faith healing and the like.
There's not much real evidence for most things going that far back apparently. Even for e.g. Hannibal there's no contemporary sources left, so can't expect much for a minor rabble raiser from a backwater on the edges of the empire like Jesus.
A key tool for historians is critical reading of the available sources, and in the case of Jesus that does include the bible texts as well.
