Ever think how that might fit with Genesis 9:5a, "And for your lifeblood I will surely demand an accounting. I will demand an accounting from every animal."
"...just as life is not "matter plus Y," but "life minus Y."
I assume that he meant that *matter* is "life minus Y", not that *life* is "life minus Y"? That would fit better with his previous statement about humans/animals.
Not if he's referring to the biblical definition of Life. Luke 9:59-62 ":...let the dead bury the dead...". God considers men to be "dead" unless they are regenerate (given "Life").
