Words associated with Christmas include Jesus, Gabriel, Kris Kringle, Hallelujah and frankincense. Additional words and phrases include Merry Christmas, Saint Nicholas, Santa Claus, Jack Frost and jingle bells. Some of these words come from the Christian origins of Christmas, whereas others come from national traditions of various countries.
The origin of Christmas lay in the birth of Jesus Christ, whom Christians consider to be the second person of the Trinity made man. Tradition has generally favored December 25th as the birth date of Jesus, and that is why Christmas is celebrated on that day. Christians also believe that the angel Gabriel delivered the message of the coming Messiah to Mary, and that Gabriel also announced the birth of Jesus to a group of shepherds.
The association of the word "Hallelujah" with Christmas comes, in part, from the famous Hallelujah Chorus of George Frederic Handel's (1685-1759) oratorio The Messiah. The word "Hallelujah" refers to praise and worship.
Frankincense is associated with the Christmas season on account on the Three Wisemen, whom some Christians believe traveled to Bethlehem to venerate the baby Jesus. Frankincense, which is the gum or resin of the Boswellia tree, was a costly and symbolic important substance during the time of Christ.
