Commemorating Jesus’ birth
Christians celebrate the birth of Jesus to the Virgin Mary as a fulfillment of the Old Testament‘s Messianic prophecy. The Bible contains two accounts which describe the events surrounding Jesus’ birth. Depending on one’s perspective, these accounts either differ from each other or tell two versions of the same story   These biblical accounts are found in the Gospel of Matthew, namely Matthew 1:18, and the Gospel of Luke, specifically Luke 1:26 and 2:40. According to these accounts, Jesus was born to Mary, assisted by her husband Joseph, in the city of Bethlehem.
According to popular tradition, the birth took place in a stable, surrounded by farm animals, though neither the stable nor the animals are specifically mentioned in the Biblical accounts. However, a manger is mentioned in Luke 2:7, where it states, “She wrapped him in cloths and placed him in a manger, because there was no room for them in the inn.” Early iconographic representations of the nativity placed the animals and manger within a cave (located, according to tradition, under the Church of the Nativity in Bethlehem). Shepherds from the fields surrounding Bethlehem were told of the birth by an angel, and were the first to see the child.
The Gospel of Matthew also describes a visit by several Magi, or astrologers, who bring gifts of gold, frankincense, and myrrh to the infant Jesus. The visitors were said to be following a mysterious star, commonly known as the Star of Bethlehem, believing it to announce the birth of a king of the Jews. The commemoration of this visit, the Feast of Epiphany celebrated on January 6, is the formal end of the Christmas season in some churches.
Christians celebrate Christmas in various ways. In addition to this day being one of the most important and popular for the attendance of church services, there are other devotions and popular traditions. In some Christian denominations, children re-enact the events of the Nativity with animals to portray the event with more realism or sing carols that reference the event. Some Christians also display a small re-creation of the Nativity, known as a Nativity scene or crèche, in their homes, using figurines to portray the key characters of the event. Prior to Christmas Day, the Eastern Orthodox Church practices the 40-day Nativity Fast in anticipation of the birth of Jesus, while much of Western Christianity celebrates four weeks of Advent. The final preparations for Christmas are made on Christmas Eve.
A long artistic tradition has grown of producing painted depictions of the nativity in art. Nativity scenes are traditionally set in a barn or stable and include Mary, Joseph, the child Jesus, angels, shepherds and the Three Wise Men: Balthazar, Melchior, and Caspar, who are said to have followed a star, known as the Star of Bethlehem, and arrived after his birth.
