Still not a spirit. An angel, but not actually a spirit, let alone a god, in itself.
So, basically, while seemingly taking an atheist, anti-religion point of view about doing so, it's still only a series showing the negativity of deceptive religious/spiritual/philosophical/moral practices. And even at that, I'd think that the main impact would be the fantasy factor, not any supposed philosophical message it portends.
“…Judge not what a man has done, but judge what he could have done if he was a different bloke altogether. For art thou a leper? And a leper can changeth his spots…” --Rudy Wade, Misfits (Series 4, Episode 8)
