JWs have come to a far different interpretation of Jewish Law by means of rejecting the culture and theology that shaped it. -DJ
NO they haven't. But they base their teachings on the "NT's'" interpretation of the "OT"
According to the Gospels, Christianity was a Jewish movement that coexisted with other Jewish movements pre 70. IT did not catch on, however, Pharisaic Judaism not being Temple based, according to Talmudic legends, survived- bais hatred or un-based, take your pick.
In the Soncino Press, (I have all the books) the publishers give some academic credit to non-Jewish commentators, referring to them as 'semi-heathen' and "by the same token," (an expression used by TD ) surviving Pharisaic Judaism like the Samaritans or even a Policeman fired from his job but who continues to presume his duty, have no authority, and their interpretations although having some academic merit (the Samaritan Pentateuch for example) is not Temple based, have no spiritual value, and also not from Jehovah. Jws interpretations of Tanakh is not baseless, made up by the wt, they are the teachings of Christianity as opposed to the teachings of surviving Judaism, and besides that, JW proclaim authority.
