In any case, none of this is to deny that Orthodox Judaism is normative Judaism, none of this is to deny Orthodoxy's legitimacy. Rather, it is simply to describe it in a historical context. That is nothing that anyone should be afraid of. As to the theological claims that Dan demands we all accept, the fact is that they are not as old as he claims. If he had merely stated that he had believed them to be true, that would have Ok.
People can choose their own beliefs.
That's bad history, and I don't see how bad history can lead to good theology. ALL unanymously agree to these principles. I know that Dan wishes such things to be true - but they are not. It was only in the 1600s when these principles were elevated to the position that the Orthodox give them today. That's a terrible charge, and totally untrue.
