The word "Christmas" is a combination of the words "Christ" and "Mass".“Christmas”这个词是“基督”和”弥撒“的缩写，弥撒是教会的一种礼拜仪式。
For today's Christian, the origin of Christmas is, and should be, the birth of Jesus Christ as recorded in the Bible. Nothing more and nothing less. However, most of what we witness on December 25th each year has absolutely nothing to do with that blessed day, which probably occurred in late summer or early fall about 2,000 years ago. In fact, most of the customs and traditions of Christmas actually pre-date the birth of Jesus, and many of them are downright deceptive in their meaning and origin. Anyway, who cares whenChrist was born?
耶诞节是一个宗教节日，世人把它当作耶稣的诞辰来庆祝，因而又名耶诞节。这一天，世界所有的基督教会都举行特别的礼拜仪式。但是有很多圣诞节的欢庆活动和宗教并无半点关联。又有人说耶稣诞生是在夏末秋初，并非圣诞之日。然而，圣诞节究竟是否耶稣诞辰之日对于现代人来说已经不那么重要，它就像我们的春节一样，大家相聚一堂，交换礼物，寄圣诞卡，吃火鸡大餐，圣诞节是一个普天同庆的日子。
