"When you see one who was not born of woman,
prostrate yourselves on your faces and worship him.
That one is your father."
The umbilicus is the physical mark
of being "born of woman".
I think the goal of the Gnostics "ascents" into
the heavens was to "ascend" to the level of the Father. They will know they have arrived when
they encounter a Being without this mark.
This reminds me of the question:
”Did Adam have a belly button?”
If so, why?
so he could have it pierced?
If the Father created Adam, then he would
be created, not born, thus Adam would also
share the title, “one who was not born of woman”.
However, if Sophia, a woman, created the
Universe of matter, and everything within it,
then only that which transcends this world
of opposites is “not born of woman".
That means your earthly body and your
genetically inherited instincts are "born of woman".
That which is “not born of woman" would include:
the twin souls of heart and mind united
through Knowledge to produce a living Spirit.
(my comment: God is not born of woman…)
