Isn't it odd that, in all the Christian world and down through all the centuries, there was never (as far as I know) any attempt to rename the twelve months of the year after the twelve disciples, especially given so many of the months are named after pagan deities?
Twelve months, twelve disciples. It fits so perfectly.
(What you would do with Judas Iscariot would be a problem, of course. One month would have to be devoted to either St. Matthias or some other figure-- Our Lord himself, our the Blessed Mother, or the Trinity, or St. Paul.)
It strikes me as odd, but I quite like the fact that this never happened. I like the fact that Christianity never tried to bulldoze all remnants of the pagan past out of existence, that it was not totalitarian.
