Today's feast is another one that got shuffled around in the NO calendar, which celebrates it on the Sunday within the Octave of Christmas (in between Christmas and New Year's); while the NO celebrates the Baptism of Our Lord in the Jordan River today, instead of on the Octave Day of the Epiphany (Jan. 13) as in the traditional Roman Rite. Such being the case, the Pope offered Mass for the Baptism of our Lord in the Sistine chapel ad orientem as has become customary for him.
What an awesome picture. Offering the Mass while staring at Michelangelo's depiction of the Last Judgment. And hey, now that people are getting used to seeing his back turned toward them, maybe he'll offer a public Tridentine Mass one of these days. What? Can't a guy hope?
