Now after Jesus was born in Bethlehem of Judea in the days of Herod the king, behold, wise men from the east came to Jerusalem, saying, “Where is he who has been born king of the Jews? For we saw his star when it rose and have come to worship him.” 
-Matthew 2:1-2

What is Epiphany?

The Feast of the Epiphany, or Manifestation (revelation) of Christ to the Gentiles, is observed on January 6th. Epiphany comes from a Greek word meaning "showing forth, appearance, manifestation, revelation." The Feast of Epiphany proclaims the good news that Jesus revealed God to all humanity.

At Christmas the church celebrates the birth of Jesus, when God entered fully into the human experience. The Feast of the Epiphany takes the Christmas proclamation a step further, when the divine revelation in Jesus was revealed to the world as the magi came from the east.

The eve of the Feast of the Epiphany (Twelfth Night) marks the end of the Christmas celebration. The Epiphany, January 6th, is followed by a period of "Sundays after the Epiphany"; the length of the Epiphany season varies in length from four to nine Sundays, depending on the date of Easter that year. The Last Sunday of Epiphany is celebrated as Transfiguration Sunday.

During the season of Epiphany we remember and recognize Jesus as God by many people in our Sunday readings: the magi, John the Baptist, Jesus' disciples, and Christians in every age, including our own. It is a time for rededicating ourselves to our own ministries and our missionary task - to continue the spread of Jesus' light in the world.
