Since Scott seems adverse to talking about this, I am bringing it to the top.

Even if you don't believe in the Bible, what role do you think the HS plays in the entire three-fold story line?

I see it reflected as gentle and nurturing. The Hebrew word for HS is feminine, leading to the possibility this figure is a woman. It would make sense if you see God as an "everything" i.e. all genders and none, then Jesus is the male and the HS would balance the triangle out with feminine energies.

Note I said possibilities. It's just something I have thought about for a while.
