The Q'ran, the Bible, the Bhagavad Gita: all these works are meant to be taken as works of non-fiction, based on the world and actual revelations/experiences had by the authors about that world's origins. As Kathy Mar sings, "
Humans wrote the Bible, God wrote the world." And that's deep and everything, but as a corollary it also means that the Bible is
fanfiction. All religious texts claim to be based in part on the words of a deity, so I suppose that's as canon as can be, but they're all different and ascribe different names and motivations to the main character, so religions are all just different fandoms.
There's a name for something that happens in fanfiction when a bad author writes in a character based on something they wish they could be,
and it's "Mary-Sue". A Mary-Sue is a character who has special powers, exotic looks, or is a previously-unheard-of relative to a main character. Everyone loves a Mary-Sue, s/he can do anything and often upstages the primary characters. Sound like anyone you know? Jesus is the biggest Mary-Sue ever. Heal the sick, throw a perfect party with bread and fish and wine for everybody, and
bring back the dead - tell me that he wasn't written to upstage his father and take the plot focus for himself. YA RLY.
Also, sometimes the Adam/Eve shippers and the Adam/Steve shippers get to sniping at each other, and you get little flame wars where people are crucified on LiveJournal for their belief in the One True Pairing. Which means that religious wars are fandom wank. And isn't "Christianity" just a candy-coated way of saying, "I ship God/Mary chan non-con"? See, nobody has real moral high ground here, and this is why we don't like the wank. Religion fandom: peace out, yo!
Now, in the TV, book, and movie fandoms, we realize that the owners will sue for trying to pass our work off as their own, or for trying to extort money out of it. So we say right up front that the original work is not ours. Seriously Muslims/Christians/Jews/Buddhists: You do not own the copyright on God. Have the balls to use the standard "don't own, don't sue" disclaimer, you trademark infringing trolls!
I swallow the ideas of others, and nine months later I'll have a headache and out will spring a shining idea, fully formed, armed, and loaded. Like Athena. How cool is it that I have tiny militant lesbians in my head? Oh, shut up, you're just jealous.
