Christmas Eve (Western churches)

Christmas Eve is the evening or entire day before Christmas Day, the festival commemorating the birth of Jesus. Christmas Day is observed around the world, and Christmas Eve is widely observed as a full or partial holiday in anticipation of Christmas Day. Together, both days are considered one of the most culturally significant celebrations in Christendom and Western society.

Christmas celebrations in the denominations of Western Christianity have long begun on Christmas Eve, due in part to the Christian liturgical day starting at sunset, a practice inherited from Jewish tradition and based on the story of Creation in the Book of Genesis: "And there was evening, and there was morning – the first day". Many churches still ring their church bells and hold prayers in the evening; for example, the Nordic Lutheran churches. Since tradition holds that Jesus was born at night (based in Luke 2:6-8), Midnight Mass is celebrated on Christmas Eve, traditionally at midnight, in commemoration of his birth. The idea of Jesus being born at night is reflected in the fact that Christmas Eve is referred to as Heilige Nacht (Holy Night) in German, Nochebuena (the Good Night) in Spanish and similarly in other expressions of Christmas spirituality, such as the song "Silent Night, Holy Night".

Many other varying cultural traditions and experiences are also associated with Christmas Eve around the world, including the gathering of family and friends, the singing of Christmas carols, the illumination and enjoyment of Christmas lights, trees, and other decorations, the wrapping, exchange and opening of gifts, and general preparation for Christmas Day. Legendary Christmas gift-bearing figures including Santa Claus, Father Christmas, Christkind, and Saint Nicholas are also often said to depart for their annual journey to deliver presents to children around the world on Christmas Eve, although until the Protestant introduction of Christkind in 16th-century Europe, such figures were said to instead deliver presents on the eve of Saint Nicholas' feast day (6 December).

Roman Catholics and high church Anglicans traditionally celebrate Midnight Mass, which begins either at or sometime before midnight on Christmas Eve. This ceremony, which is held in churches throughout the world, celebrates the birth of Christ, which is believed to have occurred at night. Midnight Mass is popular in Poland (pasterka) and Lithuania (piemenėlių mišios).

In recent years some churches have scheduled their "Midnight" Mass as early as 7 pm. This better suits the young children, whose choral singing has become a popular feature in some traditions. In Spanish-speaking areas, the Midnight Mass is sometimes referred to as Misa de Gallo, or Missa do Galo in Portuguese ("Rooster's Mass"). In the Philippines, the custom has expanded into the nine-day Simbang Gabi, when Filipinos attend dawn Masses (traditionally beginning around 04:00 to 05:00 PST) from 16 December, continuing daily until Christmas Eve. In 2009 Vatican officials scheduled the Midnight Mass to start at 10 pm so that the 82-year-old Pope Benedict XVI would not have too late a night.

A nativity scene may be erected indoors or outdoors, and is composed of figurines depicting the infant Jesus resting in a manger, Mary, and Joseph. Other figures in the scene may include angels, shepherds, and various animals. The figures may be made of any material, and arranged in a stable or grotto. The Magi may also appear, and are sometimes not placed in the scene until the week following Christmas to account for their travel time to Bethlehem. While most home nativity scenes are packed away at Christmas or shortly thereafter, nativity scenes in churches usually remain on display until the feast of the Baptism of the Lord.

Whilst it does not include any kind of Mass, the Church of Scotland has a service beginning just before midnight, in which carols are sung. The Church of Scotland no longer holds Hogmanay services on New Year's Eve, however. The Christmas Eve Services are still very popular. On Christmas Eve, the Christ Candle in the center of the Advent wreath is traditionally lit in many church services. In candlelight services, while singing Silent Night, each member of the congregation receives a candle and passes along their flame which is first received from the Christ Candle.

Lutherans traditionally practice Christmas Eve Eucharistic traditions typical of Germany and Scandinavia. "Krippenspiele" (Nativity plays), special festive music for organ, vocal and brass choirs and candlelight services make Christmas Eve one of the highlights in the Lutheran Church calendar.

Christmas Vespers are popular in the early evening, and midnight services are also widespread in regions which are predominantly Lutheran. The old Lutheran tradition of a Christmas Vigil in the early morning hours of Christmas Day (Christmette) can still be found in some regions. In eastern and middle Germany, congregations still continue the tradition of "Quempas singing": separate groups dispersed in various parts of the church sing verses of the song "He whom shepherds once came Praising" (Quem pastores laudavere) responsively.

Methodists celebrate the evening in different ways. Some, in the early evening, come to their church to celebrate Holy Communion with their families. The mood is very solemn, and the only visible light is the Advent Wreath, and the candles upon the Lord's Table. Others celebrate the evening with services of light, which include singing the song Silent Night as a variety of candles (including personal candles) are lit. Other churches have late evening services perhaps at 11 pm, so that the church can celebrate Christmas Day together with the ringing of bells at midnight. Others offer Christmas Day services as well.
