Most of Orthodox Judaism holds that the teachings of Kabbalah were transmitted from teacher to teacher, in a long and continuous chain, from the Biblical era until its redaction by Shimon bar Yochai. Some fully accept the claims that the Kabbalah's teachings are in essence a revelation from God to the Biblical patriarch Abraham, Moses and other ancient figures, but were never printed and made publicly available until the time of the Zohar's medieval publication. The greatest acceptance of this sequence of events is held within Haredi Judaism, especially Chasidic groups. R' Yechiel Michel Epstein (d.1908), and R' Yisrael Meir Kagan (d.1933) both believed in the authenticity of the Zohar. Rabbis Eliyahu Dessler (d.1953) and Gedaliah Nadel (d.2004) maintained that it is acceptable to believe that the Zohar was not written by Rabbi Shimon bar Yochai and that it had a late authorship."I approached Rav A Carmell with some of the questions on the Zohar, and he responded to me - 'and what about nikud? Nikud is also mentioned in the Zohar despite the fact that it from Geonic times!' he said. I later found this comment in the Mitpachas Seforim. I would just add that not only is nikud mentioned, but only the Tiberian Nikkud - the norm in Europe of the middle ages - is mentioned and not the Yerushalmi nikud or the Babylonian one — which was used then in the Middle East, and is still used by Yemenites today. Also the Taamay Hamikrah - the trop - are referred to in the Zohar - only by their Sefardi Names. Rav A told me a remarkable piece of testimony: 'My rebbe (this is how he generally refers to Rav E [Elijah Dessler) accepted the possibility that the Zohar was written sometime in the 13th century.
