Epiphany, (from Greek epiphaneia, “manifestation”), Christian holiday commemorating the first manifestation of Jesus Christ to the Gentiles, represented by the Magi, and the manifestation of his divinity, as it occurred at his baptism in the Jordan River and at his first miracle, at Cana in Galilee. Epiphany is one of the three principal and oldest festival days of the Christian church (the other two are Easter and Christmas). Roman Catholics, Lutherans, Anglicans, and other Western churches observe the feast on January 6, while some Eastern Orthodox churches celebrate Epiphany on January 19, since their Christmas Eve falls on January 6.
The festival originated in the Eastern church, where it at first included a commemoration of Christ’s birth. In Rome, by 354 Christ’s birth was being celebrated on December 25 (Christmas), and later in the 4th century the church in Rome began celebrating Epiphany on January 6. In the Western church the festival primarily commemorates the visit by the Magi to the infant Jesus, which is seen as evidence that Christ, the Jewish Messiah, came also for the salvation of Gentiles. In the East it primarily commemorates the baptism of Jesus and celebrates the revelation that the incarnate Christ was both fully God and fully man.
In the West the evening preceding Epiphany is called Twelfth Night. The time between December 25 and January 6 is known as the Twelve Days of Christmas. Epiphany is celebrated with special pastries in many countries, and children often receive small gifts in their shoes in honour of the Magi’s gifts to the infant Jesus. The holiday also has a number of traditions involving water as a reflection of Jesus’ baptism, including the blessing of houses with holy water.
