Persephone is just a name for a spirit of beauty at a certain time in history. I'm sure we could argue a biblical place for her if it matters. Your wife has the name of that pagan goddess, but the fact remains that she's your mortal bride in the Year of Our Lord 1888- and she's Catholic, so pray for her, damn it, I don't care how confusing it is. And pray for us, to anyone. If the dead are about to flood Athens, divine goodwill couldn't hurt. Your prayers can be in Hindu, if you like. Now go home.
