The name Christmas is short for "Christ's Mass". A Mass is a kind of Church service. Christmas is a religious festival. It is the day we celebrate as the birthday of Jesus.

There are special Christmas services in Christian churches all over the world. But many of the festivities of Christmas do not have anything to do with religion. Exchanging gifts and sending Christmas cards are the modern ways of celebrating the Christmas in the world.

The birth of Jesus had a story: In Nazareth, a city of Galilee. The virgin's name was Mary was betrothed to Joseph. Before they came together, she was found with child of the Holy Spirit. Joseph her husband was minded to put her away secretly. While he thought about these things, Gabriel, an angel of the Lord appeared to him in a dream and told him did not be afraid to take Mary as wife. And Mary will bring forth a Son, and he shall call his name, Jesus, for he will save his people from their sins.

Before Jesus births, Joseph and Mary came to Quintus was governing Syria. So all went to be registered, everyone to his own city. Joseph also went up out of Galilee, out of the city of Nazareth, into Judea, to the city of David, which is called Bethlehem, because he was of the house and of the lineage of David, to be registered with Mary, his betrothed wife, who was with child. So it was that while they were there, the days were completed for her to be delivered. And she brought forth her firstborn Son, and wrapped him in swaddling cloths, and laid him in a manger, because there was no room for them in the inn.And that, Christmas is the feast of the nativity of Jesus, is on 25th, December every year. But nobody know the actual birthday of Jesus. And the Christmas has become popular when Christmas cards appeared in 1846 and the concept of a jolly Santa Claus was first made popular in nineteenth Century.

“圣誕節”這個名稱是“基督彌撒”的縮寫。彌撒是教會的一種禮拜儀式。耶誕節是一個宗節我們把它當作耶蘇的誕辰來慶祝，因而又名耶誕節。這一天，世界所有的基督教會都舉行特別的禮拜儀式。但是有很多圣誕節的歡慶活動和宗教并無半點關聯。交換禮物，寄圣誕卡，這都使圣誕節成為一個普天同慶的日子。

圣誕節是基督教世界最大的節日。4世紀初，1月6日是羅馬帝國東部各教會紀念那穌降生和受洗的雙重節日、稱為“主顯節”Epiphany，亦稱“顯現節”即上帝通過那穌向世人顯示自己。當時只有那路拉冷的教會例外，那里只紀念耶穌的誕生而不紀念那穌的受洗。后來歷史學家們在羅馬基督徒習用的日歷中發現公元354年12月25日頁內記錄著：“基督降生在猶大的伯利恒。”經過研究，一般認為12月25日伴為圣誕節可能開始于公元336年的羅馬教會)約在公元375年傳到小亞細亞的安提阿，公元430年傳到埃及的亞歷山大里亞，那路撒冷的教會接受得最晚，而亞美尼亞的教會則仍然堅持1月6日主顯節是那穌的誕辰。
