A random Supernatural Thought
Let me start this by saying I grew up Catholic, but I was in a singing group that did a lot of ecumenical services in churches of other faiths. So I saw the differences and sameness of many "different" religions. I also read a lot; as a kid I took the Aslan/Tash thing in the end of The Chronicles of Narnia probably totally the opposite of what C.S. Lewis intended. All my sci-fi fantasy reading has made me believe in everything, and nothing. So my views religion and God and gods are not the norm.
Okay, I know that Castiel opened Purgatory and absorbed all the souls inside. (Although I wonder...did he absorb ALL the souls, or just the human souls? And if he didn't take the monster souls, are they now free to roam the Earth again? But that's not my question...)
I've seen a bunch of posts where people are annoyed or enraged or even laughing hysterically because they think that Castiel thinks he's God. But...this is Supernatural, right? We've already seen that there are a ton of gods running around. Hindu gods, Viking gods, Greek gods...they're out there. Apparently their power waxes and wanes because of belief. That's why they older gods have lost power, and the Christian god has taken on more and more. (although I would think that would make the gods of India and China the most powerful, but I realize this is being filmed by people with a Judeo-Christian background, so that will probably never be acknowledged.)
While it's true that absorbing Purgatory's souls may have given Castiel god-like powers, doesn't he have to have worshippers to make it official? Or has the Christian god left the post so open that anybody can just step into it? If that's true, why didn't Uriel (or Zachariah) simply absorb extra souls or a bunch of other angels, or an arch-angel or two and take over Heaven millenium ago? If the show is saying that power is the only thing that makes God, wouldn't you think that one of the other, greedier pagan gods would have taken over long ago?
Anyway, it doesn't seem possible that we can expect Castiel to just step right into God's shoes and take over heaven absolutely. I think he has just as many problems as he did before, and this time, he has no one on his side. We haven't seen if the angels will accept him, it looks like Crowley is opposed to him (although that could be wrong) and he no longer has the Winchesters. It leaves a bunch of options open.
I don't know that there's any answer to this until season seven starts, but I just don't think "god-like powers" equals The God. It will be interesting to see where they go with this. I guess it just doesn't seem as cut and dried as it seems to look.
Ansower if you like, but I'm trying to stay spoiler-free as much as possible. Anything published in TV guide is fair game, but leaks from the set are not. Thanks!
