In any event, one of the features of the findings from the caves were pairs of tefillin (phylacteries). These prayer ritual items are not mentioned in the Torah and are derived from the teachings of the rabbis in Rabbinic Judaism known as the Oral Law. Any sect that used these items had to have believed in the authority of rabbis even from previous generations. Thus, this itself calls into question again the theory that the findings of Qumran were exclusively items of non-rabbinic sects. The more I reread the material the more I say to myself that the author(s) is not NECESSARILY a non-rabbinic Jew.
