Today (November 20) on the traditional Roman calendar is the feast of St. Felix of Valois (†1212). Who is this obscure saint, you might ask, and why is he cluttering our calendar? Would it not be fitting to cancel him out? And so, indeed, it was done in the 1969 Novus Ordo calendar: Felix evaporated into thin air, or rather, retreated to his page in the Martyrology where few souls remember him.
