Star of Bethlehem in the context of "Christmas tree"

A Christmas decoration is any of several types of ornamentation used at Christmas and the greater Christmas and holiday season. Typical images on Christmas decorations include Baby Jesus, Mother Mary, angels, Father Christmas, Santa Claus, and the star of Bethlehem. Advent wreaths, nativity scenes, illuminations, and Moravian stars are popular Christmas decorations.

In many countries, such as Sweden, people start to set up their Advent and Christmas decorations on the first day of Advent. Liturgically, this is done in some parishes through a Hanging of the Greens ceremony. In the Western Christian world, the two traditional days when Christmas decorations are removed are Twelfth Night and if they are not taken down on that day, Candlemas, the latter of which ends the Christmas-Epiphany season in some denominations. Taking down Christmas decorations before Twelfth Night, as well as leaving the decorations up beyond Candlemas, is historically considered to be inauspicious.

In the Christian tradition, a nativity scene (also known as a manger scene, crib, crèche (/krɛʃ/ or /kreɪʃ/), or in Italian presepio or presepe, or Bethlehem) is the special exhibition, particularly during the Christmas season, of art objects representing the birth of Jesus. While the term "nativity scene" may be used of any representation of the very common subject of the Nativity of Jesus in art, it has a more specialized sense referring to seasonal displays, in particular sets of individual sculptural figures and props that are arranged for display.

Other characters from the nativity story, such as shepherds, sheep, and angels may be displayed near the manger in a barn (or cave) intended to accommodate farm animals, as described in the Gospel of Luke. A donkey and an ox are typically depicted in the scene, and the Magi and their camels, described in the Gospel of Matthew, are also included. Many also include a representation of the Star of Bethlehem. Several cultures add other characters and objects that may or may not be Biblical.

The Adoration of the Magi or Adoration of the Kings or Visitation of the Wise Men is the name traditionally given to the subject in the Nativity of Jesus in art in which the three Magi, represented as kings, especially in the West, having found Jesus by following a star, lay before him gifts of gold, frankincense, and myrrh, and worship him. It is related in the Bible by Matthew 2:11: "On entering the house, they saw the child with Mary his mother; and they knelt down and paid him homage. Then, opening their treasure chests, they offered him gifts of gold, frankincense, and myrrh. And having been warned in a dream not to return to Herod, they left for their own country by another path".

Christian iconography considerably expanded the bare account of the Biblical Magi described in the Gospel of Matthew (2:1–22). By the later Middle Ages this drew from non-canonical sources like the Golden Legend by Jacobus de Voragine. Artists used the expanded Christian iconography to reinforce the idea that Jesus was recognized, from his earliest infancy, as king of the earth. The adoration scene was often used to represent the Nativity, one of the most indispensable episodes in cycles of the Life of the Virgin as well as the Life of Christ.

A Moravian star (German: Herrnhuter Stern) is an illuminated decoration used during the Christian liturgical seasons of Advent, Christmas, and Epiphany representing the Star of Bethlehem pointing towards the infant Jesus. The Moravian Church teaches:

The Moravian star is popular in places where there are Moravian Christian congregations world wide. The stars take their English name from the Moravian Church, originating in Moravia. In Germany, they are known as Herrnhut stars, named after the Moravian Mother Community in Saxony, Germany, where they were first commercially produced. With the rise of ecumenism, the use of the Moravian star has spread beyond the Moravian Church to other Christian denominations, such as the Lutheran Church and Catholic Church, as well as the Methodist Church.

A Christmas card is a greeting card sent as part of the traditional celebration of Christmas in order to convey between people a range of sentiments related to Christmastide and the holiday season. Christmas cards are usually exchanged during the weeks preceding Christmas Day by many people (including some non-Christians) in Western society and in Asia. The traditional greeting reads "wishing you a Merry Christmas and a Happy New Year". There are innumerable variations on this greeting, many cards expressing more religious sentiment, or containing a poem, prayer, Christmas song lyrics or Biblical verse; others focus on the general holiday season with an all-inclusive "Season's greetings". The first modern Christmas card was by John Calcott Horsley.

A Christmas card is generally commercially designed and purchased for the occasion. The content of the design might relate directly to the Christmas narrative with depictions of the Nativity of Jesus, or have Christian symbols such as the Star of Bethlehem or a white dove representing both the Holy Spirit and Peace. Many Christmas cards show Christmas traditions, such as seasonal figures (e.g., Santa Claus, snowmen, and reindeer), objects associated with Christmas such as candles, holly, baubles, and Christmas trees, and Christmastime activities such as shopping, caroling, and partying, or other aspects of the season such as the snow and wildlife of the northern winter. Some secular cards depict nostalgic scenes of the past such as crinolined shoppers in 19th-century streetscapes; others are humorous, particularly in depicting the antics of Santa and his elves.
