Years and years ago - I mean, literally, way back in the early 1990s - I wrote a Bible slash story, set in the gospels. It was way inexplicit, but...
...given what British blasphemy law is like, I sent it to be published in Australia (one of the Homosapien zines: "Why Shouldn't It Be Me?"), and it's still not up on my website.
OTOH, the UK government are contemplating repealing the blasphemy law, and if they do, whee!, I'm going to celebrate in lots of slashy ways.
I didn't use to be that keen on Bible slash as a genre, but then I encountered Daegaer, who writes lovely Bible slash and other Bible fanfic. (I don't think she has a website: everything's on livejournal in her well-organised Memories.)
