The only evidence we have that Josiah was a "Yahwist" is his name with its reference to Yah (iah). The worship of Yah was not a monotheistic belief as we know from the archaeological record. There is no reason to believe Josiah was a monotheist and no reason at all to believe he was a reformer. We have no evidence for either claims.outhouse wrote: But I do believe that under Josiah we did have monotheistic reforms to loyalty to Yahweh alone, as he is said to be a loyal Yahwist and there is little reason to doubt this.
I am amazed at the number of times I read someone saying "there is no reason to doubt" such and such a statement in the Bible. If there is no reason to doubt there is equally no reason to believe, either. There is no evidence either way. We just don't know.
But we do know the stories in the Bible are theological tracts advocating a particular religious belief so we would expect scholars to be a little wary about believing any of their claims without supporting evidence.
But it seems the fear of not knowing either way is intolerable for some of us and so the default is "there is no reason to doubt".
A genuine scholarly method would be to ask what a certain claim would lead us to expect to find in the "hard evidence" of archaeological remains or other independent sources. If we find it then we may have some reason to believe; if we don't then we have every right to doubt.
Doubting doesn't mean outright rejection. It means simply not knowing. Blank. Black hole. Bottomless pit. Nothing either way.
It means we can't study or use the claim as a historical source and do history with it. It means the source is good for many things but not for the real history of Josiah.
