Lilith isn't in the document, period. If you're going to add stuff that isn't in the Christian interpretation, you can't use it to criticize the Christian interpretation.
Unless I misunderstood Greatest I am, he isn't referring to the Christian interpretation.
Greatest I am said:This is a Jewish document. Genesis 1 was Lillith. Something Christians conveniently forget.
It would seem he is referring to the Jewish holy texts. Perhaps the talmud, torah or something, I'm not familiar with the Jewish holy books.
