According to Israel Shahak in Jewish History Jewish Religion: The Weight of Three Thousand Years: In Jewish mysticism non-Jews are considered to be literally limbs of Satan. The few non-satanic individuals among them (that is those who convert to Judaism) are in reality “Jewish souls” who got lost when Satan violated the Holy Lady (Shekhinah or Matronit one of the female components of the God-head sister and wife of the younger male God according to the Cabbala) in her heavenly abode. Shahak notes that these facts about the attitude of Jewish mysticism to non-Jews are absent from numerous English-language Jewish histories and that authorities like Gershom Scholem have lent their authority to a system of deceptions in sensitive areas the more popular ones being the most dishonest and misleading.
