I pulled out his “The Phenomenology of Mind” and scanned a few chapters. Chapter VI, on Spirit strikes me as more humanist in perspective than Christian.
“Reason is spirit, when its certainty of being all reality has been raised to the level of truth, and reason is consciously aware of itself as its own world, and of the world as itself.”
IMHO, definitely not the human spirit of Pauline or Johanine writings.
For one thing, neither "spirit" nor "mind" adequately translate "Geist" as Hegel uses the word. And I think while he has, or thinks he has, Xtian influences in his thought, he is not trying to be a theologian. In the "Athens v. Jerusalem" division, he's sho' nuff on the Athens side, by way of German Idealism.
