Religious Significance Although the four Gospels in the New Testament differ in their accounts, the common Christmas narrative of the birth of Jesus associated with Christmas starts with Mary, who agrees to bear the Son of God after Angel Gabriel announces the news to her. The Gospel of Luke goes on to describe the travels of Joseph and the pregnant Mary from Nazareth to Bethlehem to take the census, and the subsequent birth of Jesus. Mary places the baby in a manger because there is no room for them in an inn. Angels proclaim him Messiah or the Christ, shepherds come to adore him, and kings or wise men come bearing gifts of gold, frankincense and myrrh. The feast of Epiphany commemorates the wise men's arrival, and in some communities is more widely celebrated than Christmas Day. Some traditions celebrate the baptism of Jesus on this day as well. Traditions Christmas celebrations vary widely around the world. Nativity plays and Christmas pageants that depict the story of the birth of Christ are often performed around Christmas. Festive carols are sung, as people celebrate the warm and joyous season. Many families place gifts under a beautifully decorated Christmas tree, to open on Christmas morning. Church services on Christmas Eve and Christmas Day are popular with many people. Christmas is a time to celebrate faith and family. Santa Claus, or St. Nick, is a popular part of Christmas in many countries. The fantastical character arrived in American in the nineteenth century, as new German immigrants arrived with the traditions of the Christmas tree, Christmas gifts and the story of St. Nicholas. By the end of the century, Santa Claus was an important part of Christmas in the United States. American children believe he travels from the North Pole in a flying sleigh pulled by reindeer to deliver gifts on Christmas Eve. He fills their Christmas stockings with treats, and enters and exits the house through the chimney. The name "Santa Claus" comes from St. Nicholas' nickname of "Sinter Klaas" in Dutch. St. Nicholas was born in the third century, in a village on Turkey's southern coast. He was known as a protector and helper of children, as well as the poor, and was associated with gift-giving due to stories about his generosity. He became the Bishop of Myra later in his life, and his tomb became a popular pilgrimage site after his death. History Of Christmas History.com's feature on the history of Christmas says: In the early years of Christianity, Easter was the main holiday; the birth of Jesus was not celebrated. In the fourth century, church officials decided to institute the birth of Jesus as a holiday. Unfortunately, the Bible does not mention date for his birth (a fact Puritans later pointed out in order to deny the legitimacy of the celebration). Although some evidence suggests that his birth may have occurred in the spring (why would shepherds be herding in the middle of winter?), Pope Julius I chose December 25. It is commonly believed that the church chose this date in an effort to adopt and absorb the traditions of the pagan Saturnalia festival. First called the Feast of the Nativity, the custom spread to Egypt by 432 and to England by the end of the sixth century. By the end of the eighth century, the celebration of Christmas had spread all the way to Scandinavia. Today, in the Greek and Russian orthodox churches, Christmas is celebrated 13 days after the 25th, which is also referred to as the Epiphany or Three Kings Day. This is the day it is believed that the three wise men finally found Jesus in the manger. Merry Christmas!
