Today is not just any day in Advent, it's also the Catholic Feast of the Immaculate Conception of Mary.
A conversation I had today reminded me that I should inform any of our faithful readers who are not yet aware that the Immaculate Conception does not refer to the conception of Jesus, but of Mary. This day celebrates the conception of Mary, free from the stain of original sin (a Catholic doctrine that is set to many different lovely tunes that were sung by Nicaraguans last night and today). La Purísima (the Most Pure, an adjective describing Mary) is particularly important in Nicaragua -- it's the aspect of Mary that Nicaragua (this has become "Nicaraguan Catholics," as the non-Catholic population has grown considerably in recent decades) celebrates in a special way.
In the ecumenical spirit, I offer you this awesome video made by a Methodist youth group, "Call Me Mary":
I might like this even better than the Cookie Monster version!
