SF Mass

Usually 'mass' in science fiction is used as a scientific term. But here's the other kind. [via Sci-Fi Catholic]

I'm trying to think of other examples of sf Masses, but all that's coming to mind are the ones in Gene Wolfe's Book of the Short Sun. They're not technically Masses (nary a Catholic priest in sight), either, but they are definitely Eucharistic celebrations with bread and wine (or water), and even words that come close to the Earth version. Horn (or Silk? hard to say) performs them twice. Once out in a wilderness on the planet Blue, on a stone altar left by departed aliens, with only his horse to participate. (Though during it Someone Else makes his presence known.) The other time it's with a young female robot (no, really) in an obscure room in a fancy hotel in the city of Viron, inside of the giant generational starship the Whorl.

I suppose there are Masses in Eifelheim and Doomsday Book. But those aren't futuristic.
