We are presently in the season of Epiphanytide, which occurs within Christmastide. The third Sunday after Epiphany is a Second-Class feast. For such a feast, the priest wears green, and that typically calls for Mass IV (for Ordinary Feasts) or Mass XI (for Sundays throughout the Year). We opted for Mass XI and paired that with Credo I.
Hanging on to Christmastide just a little longer, we sang Sleep, Holy Babe at the processional.
At the Offertory, still in the Christmas spirit, we sang Corde Natus ex Parentis.
January being the month of the Holy Name of Jesus, we sang Jesu Dulcis Memoria and Ecce Nomen Domini.
For the recessional, we sang the utterly delightful little Christmas tale, Noël Nouvelet, a very loose English translation of a French carol from the end of the 15th century.
