Today’s feast used to usher in a forty-day period of fasting prior to Christmas. Actually, St Martin’s Day, or Martinmas, was a day more akin to Mardi Gras, with much revelry and feasting. The traditional dinner for the day is goose, which connects to the legend of Martin joining a stable full of geese to hide from those who would make him bishop. Would that we had such reluctant bishops today!
Pope Benedict had some good words on the soldier-turned-monk-turned-bishop.
