Epiphany is a Christian feast day that celebrates the revelation of God in human form in the person of Jesus Christ. The term Epiphany means "to show" or "to make known" or even "to reveal." It falls on 6th January or, in many countries, on the Sunday that falls between 2 January and 8 January. Since the Julian Calendar, which is followed by some Eastern Churches, is at present 13 days behind the Gregorian Calendar and the revised Julian Calendar, 6th January in that calendar corresponds at present to 19 January in what is the official civil calendar in most countries. Today, most of the Eastern Orthodox traditions follow the western church calendar. The exceptions are some Greek Orthodox Churches and related traditions (for example, Russian and Serbian Orthodox) that still follow the older calendar and celebrate Epiphany as the Theophany on January 19th. On this feast, Western Christians commemorate principally the visitation of the Biblical Magi to the Baby Jesus, i.e., his manifestation to the Gentiles; Eastern Christians commemorate the baptism of Jesus in the Jordan River, seen as his manifestation to the world as the Son of God.
The observance had its origins in the Eastern Christian Churches, and was a general celebration of the Incarnation of Jesus Christ. It included the commemoration of: his birth; the visit of the Magi ("Wise Men", as Magi were Persian priests) to Bethlehem; all of Jesus' childhood events, up to and including his baptism in the Jordan by John the Baptist; and even the miracle at the Wedding of Cana in Galilee. Baptism was clearly, the primary event being commemorated. The earliest reference to Epiphany as a Christian feast was in A.D. 361, by Ammianus Marcellinus. St. Epiphanius says that January 6th is hemera genethlion toutestin epiphanion (Christ's "Birthday; that is, His Epiphany"). He also asserts that the Miracle at Cana occurred on the same calendar day. In 385, the pilgrim Egeria (also known as Silvia) described a celebration in Jerusalem and Bethlehem, which she called "Epiphany" (epiphania) that commemorated the Nativity of Christ. Even at this early date, there was an octave associated with the feast.
In a sermon delivered on December 25, 380, St. Gregory of Nazianzus referred to the day as ta theophania ("the Theophany", an alternative name for Epiphany), saying expressly that it is a day commemorating he hagia tou Christou gennesis ("the holy nativity of Christ") and told his listeners that they would soon be celebrating the baptism of Christ. Then, on January 6 and 7, he preached two more sermons, wherein he declared that the celebration of the birth of Christ and the visitation of the Magi had already taken place, and that they would now commemorate his Baptism. At this time, celebration of the two events was beginning to be observed on separate occasions, at least in Cappadocia. Saint John Cassian says that even in his time (beginning of the 5th century), the Egyptian monasteries celebrated the Nativity and Baptism together on January 6. The Armenian Apostolic Church continues to celebrate January 6 as the only commemoration of the Nativity.
Epiphany is celebrated by both the Eastern and Western Churches, but a major difference between them is precisely which events the feast commemorates. For Western Christians, the feast primarily commemorates the coming of the Magi; Eastern churches celebrate the Baptism of Christ in the Jordan. In both traditions, the essence of the feast is the same: the manifestation of Christ to the world (whether as an infant or in the Jordan), and the Mystery of the Incarnation.
Western Christian Churches Celebrations
Even before the year 354, the Western Church had separated the celebration of the Nativity of Christ as the feast of Christmas and set its date as December 25; it 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. Hungarians, in an apparent reference to baptism, refer to the January 6 celebration as Vízkereszt or "water cross".
Liturgical practice in Western Churches - The West historically observed a twelve-day festival, starting on December 25, and ending on January 5, known as Christmastide or the Twelve Days of Christmas. Some Christian cultures, especially those of Latin America and some in Europe, extend the season to as many as forty days, ending on Candlemas (February 2).
Eastern Orthodox Christian Churches Celebrations
Today in Eastern Orthodox churches, the emphasis at this feast is on the shining forth and revelation of Jesus Christ as the Messiah and Second Person of the Trinity at the time of his baptism. It is also celebrated because, according to tradition, the baptism of Jesus in the Jordan River by St. John the Baptist marked one of only two occasions when all three Persons of the Trinity manifested themselves simultaneously to humanity: God the Father by speaking through the clouds, God the Son being baptised in the river, and God the Holy Spirit in the shape of a dove descending from heaven (the other occasion was the Transfiguration on Mount Tabor). Thus the holy day is considered to be a Trinitarian feast. The Orthodox consider Jesus' Baptism to be the first step towards the Crucifixion, and there are some parallels in the hymnography used on this day and the hymns chanted on Good Friday.
Liturgical practice in Eastern Churches - The liturgical Forefeast of Theophany begins on January 1, and concludes with the Paramony on January 5. The Eve of the Feast is called Paramony. Paramony is observed as a strict fast day, on which those faithful who are physically able, refrain from food until the first star is observed in the evening, when a meal with wine and oil may be taken.
The symbols include either three crowns or a single crown, various portrayals of the Magi or Wise Men, three gifts, a five pointed star, or a combination of a star and crown. A more modern symbol of Epiphany is a globe or a stylized portrayal of the world. The colours of Epiphany are white and gold, the colours of celebration, newness, and hope that mark the most sacred days of the church year. In traditions that only observe a single day for Epiphany, the colours are often changed after Epiphany to the colours of Ordinary Time, usually green or thematic sanctuary colours, until Transfiguration Sunday, the last Sunday before the beginning of Lent. The colours for Transfiguration Sunday are usually the colours of Holy Days, white and gold.
Around January 6, the symbol +C+B+M+ with two numbers before and two numbers after (for example, 20+C+B+M+10) is sometimes seen written in chalk above the doorway of Christian homes. The letters are the initials of the traditional names of the Three Magi: Caspar, Melchior and Balthasar. These letters also abbreviate the Latin phrase Christus mansionem benedicat, "May Christ bless the house." The beginning and ending numbers are the year, 2010 in the example above. The crosses represent Christ. Marking the lintels of doorways is an old European practice that originally had overtones of magic (protection of the house). However, the symbols are now used throughout the world and usually represent a traditional Epiphany prayer and blessing.
Theophany, Three Kings’ Day ( In Spanish: el Dia de los Tres Reyes, la Fiesta de Reyes, or el Dia de los Reyes Magos. In Dutch -Driekoningendag), Timkat (Ethiopian Orthodox Church), Denho (means up-going by Syriac Christians), in Ireland it is called Little Christmas or Women's Christmas (Nollaig na mBan - local name).
