Not at all. No doubt there are hundreds of them who are very sensible and know a great deal about the history of Judeo-Christian religion.
But this is not an objective field of study to begin with. This is a field of study which is based in religious beliefs about the supernatural ... that's what the biblical writing is all about.
You can of course try to study what was said about Jesus in non-Christian more historical writing of that time. But as soon as you do that you find that almost none of the historical writers of the time even mentioned anyone called Jesus. And the few that did mention him, such as Tacitus and Josephus, not only made no more the very briefest of passing mention, but were plainly and unarguably only writing hearsay repetition of what Christians themselves preached and believed at that time (about 100 years after they all thought the messiah had died).
You don't think these religious texts can tell us anything other than Theology? I think there are a lot of people who will disagree with that.
