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. 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. — Ceremonies of the Liturgical Year, Msgr. Peter J. Elliott, Ignatius Press.

Today we celebrate the baptism of Christ in the Jordan. This is the second epiphany, or manifestation, of the Lord. The past, the present, and the future are made manifest in this epiphany. The most holy one placed Himself among us, the unclean and sinners. The Son of God freely humbled Himself at the hand of the Baptist. By His baptism in the Jordan, Christ manifests His humility and dedicates Himself to the redemption of man. He takes upon Himself the sins of the whole world and buries them in the waters of the Jordan. — The Light of the World by Benedict Baur, O.S.B.
