Why does Xmas stand for Christmas?

Xmas stands for Christmas and represents the Christian celebration in a significant manner. X is the symbol of Christ in Greek text, and is a meaningful term for the holiday.
Christmas is a time of great joy and symbolism for Christians around the world. It seems that every year Christians become upset with the word Xmas because they do not understand the meaning, history or symbolism of Xmas. The use of Xmas is really not an attack on the Christian celebration, as it is often perceived to be. Xmas is a historic word that is truly interchangeable with Christmas, but the word tends to upset people who see it as a disrespectful derogatory shortening of the Christian holiday. Christians may exclaim ‘Keep the Christ in Christmas,’ not realizing that X is actually the ancient symbol for Christ.

X Stands for Christ

Xmas is derived from a mixture of Greek and English. Greeks used X as the symbol for Chi, Christo or Xristo. X is the Greek symbol for Christ. In early Christian times, X was used as the symbol for Christ himself.
The exact origin of X for Christ is difficult to pinpoint. Some Bible theologians claim that the origin began in the first century AD, along with other symbols. Other Bible theologians believe that its use became widespread around the thirteenth century along with other Christian abbreviations and symbols that became popular in the Middle Ages.
It is believed that during the early Christian era, Christians put an X symbol above their door to identify themselves to each other while keeping their faith secret in a society that persecuted Christians, although this is difficult to verify.

Gutenberg Printing Press

Johannes Gutenberg invented the printing press in Germany in 1436. During the fifteenth century, in the early days of printing, each letter was individually set by placing a block in a strip. Typesetting was tedious and was an expensive part of printing. In order to save time and money, religious printing commonly used X for Christ.

Xmas History Forgotten

The history of X was commonly known and understood until recent generations. History has a way of fading as commonly known information is neglected and not passed on. Recent generations have lost knowledge of the origin of X, causing Xmas to be misunderstood.
Xmas is a word that has a long Christian history. Although many commercial entities may think they are cutting Christ out of Christmas when they use the term Xmas, the opposite is true. X stands for Christ and Xmas and Christmas are the same word.
