"I will put emnity between you and the woman..."
The line is taken from an antiphon in the Divine Office for today, the Feast of the Immaculate Conception. It does not commemorate the visit of the Angel Gabriel to Mary (as is often assumed by popular belief), but the conception of Mary herself, free from the stain of original sin, within the womb of her mother Anne. For Catholics, this is a holyday of obligation. So I'm duckin' outa here during the lunch break for Mass.
For what it's worth, this is also the day when, twenty-five years ago, former Beatle John Lennon was assassinated outside his Manhattan apartment building.
