I’m trying to recall the title and author of a short story I read many years ago. I’m relatively sure it appeared in Omni magazine sometime in the 1970s, but I could be wrong about that.
The basic idea is a reversal of the Christian ceremony of communion: instead of people eating God, God eats people. Astronauts travelling to some distant world create an interplanetary incident because of their inappropriate reaction when the god of this alien world eats one of them, which is supposed to be a great honor.
I can’t remember much more than that. If you can, and can point me to a book (or even better, a Web site) that has the story, I’d be very grateful.
