Or generally used to make the difference between what christians think their god is and what the hebrew have always understood g-d to be.
It's always idiotic to see christians telling even rabbis what their book actually says and means.
Not that 15th dalai numbskull lama would understand.
As far as i read Q&A from his profile he just got interested in religion so as to make a bit of money on the side.
