Running at New York's Playwrights Horizons just now is Mr. Burns, A Post Electric Play, Anne Washburn's story about stories and storytelling. As the following clips reveal, it's set during an apocalypse where The Simpsons is being reinvented in a whole new way.
This is the play's New York debut but the first production was staged by Washington DC's Wolly Mammoth Theatre Company in 2012. They too produced a video with plenty of excerpts.
There's a long history of apocalyptic fictions in which characters strive to recreate or understand texts from the pre-apocalypse, and oftentimes attach religious significance to what they find – Riddely Walker, A Canticle For Lebowitz, Zardoz. I'm not sure how far Mr. Burns is going down this road at all, which actually makes it seem like a rather fresh response to old ideas.
Having said that, I know people who pretty much place the burden of gospel on The Simpsons already so it wouldn't have been too much of a stretch.
