“They rated the Kabbalah highly, not (or not only) as an original Jewish doctrine but as a supposed basis of every religious or esoteric tradition.” […] Thus the Kabbalah was considered by Masonic authors to be ancient wisdom, received by the Jews directly from God and retained in some ancient esoteric schools but primarily in the secret doctrine of the Jews. … Moreover, the very idea of a secret wisdom transmitted from time immemorial through many generations of an elect would be expected to have an effect on the Masonic notion of tradition. It seems that the Russian brothers basically shared the conception of the Kabbalah commonly accepted by the Jews as ancient knowledge granted to the chosen people through revelation. Of course, they were acquainted with the opinion of European scholars, including some Hebraists of the eighteenth century, that the Kabbalah is either an invention emerging in the late Middle Ages or an adaptation of some Gnostic and/or Neoplatonic ideas within Jewish theology.”
