The Solemnity of the Epiphany is celebrated either on January 6 or, according to the decision of the episcopal conference, on the Sunday between January 2 and January 8. This year, we celebrate on January 8th.
The young Messiah is revealed as the light of the nations. Yet, as the antiphon for the Magnificat at Second Vespers reminds us, three mysteries are encompassed in this solemnity: the adoration of the Christ Child by the Magi, the Baptism of Christ and the wedding feast at Cana.
Extra candles and/or lamps may be placed around the sanctuary and in other parts of the church to honor Christ revealed as the Light of the Gentiles (Ceremonial of Bishops). It is customary to replace the images of the shepherds at the crib with the three Magi and their gifts.
