Epiphany

The Gospel of Matthew describes a visit by several Magi, or astrologers, who bring gifts of gold, frankincense, and myrrh to the infant Jesus. The visitors were following the Star of Bethlehem, believing it announced the birth of a king of the Jews. 

The commemoration of this visit, the Feast of Epiphany celebrated on January 6, is the formal end of the Christmas season.  Even before the year 354 Christians reserved January 6 as a commemoration of the manifestation of Christ, especially to the Magi, but also at his baptism and at the wedding feast of Cana.

In the New Testament the word is used in 2 Timothy 1:10 to refer either to the birth of Christ or to his appearance after his resurrection, and five times to refer to the Second Coming.  We traditionally emphasized the "Revelation to the Gentiles" mentioned in Luke, where the term Gentile means all non-Jewish peoples. The Biblical Magi, who represented the non-Jewish peoples of the world, paid homage to the infant Jesus in stark contrast to Herod the Great (King of Judea), who sought to kill him.
