56. Nice Greek letters: Chi Ro, look like X P overlaid

Abbreviations used as Christian symbols have a long history in the church. The letters of the word "Christ" in Greek, the language in which the New Testament was written, or various titles for Jesus early became symbols of Christ and Christianity. For example, the first two letters of the word Christ (cristoV, or as it would be written in older manuscripts, CRISTOS) are the Greek letters chi (c or C) and rho (r or R). These letters were used in the early church to create the chi-rho monogram (see Christian Symbols: Christmas Ornaments), a symbol that by the fourth century became part of the official battle standard of the emperor Constantine. >snip<

The exact origin of the single letter X for Christ cannot be pinpointed with certainty. Some claim that it began in the first century AD along with the other symbols, but evidence is lacking. >snip<
In any case, by the fifteenth century Xmas emerged as a widely used symbol for Christmas. >snip<

In religious publications, the church began to use the abbreviation C, or simply X, for the word "Christ" to cut down on the cost of the books and pamphlets. From there, the abbreviation moved into general use in newspapers and other publications, and "Xmas" became an accepted way of printing "Christmas" (along with the abbreviations Xian and Xianity). >snip<

So there is no grand scheme to dilute Christianity by promoting the use of Xmas instead of Christmas. It is not a modern invention to try to convert Christmas into a secular day, nor is it a device to promote the commercialism of the holiday season. Its origin is thoroughly rooted in the heritage of the Church. It is simply another way to say Christmas, drawing on a long history of symbolic abbreviations used in the church. In fact, as with other abbreviations used in common speech or writing (such as Mr. or etc.), the abbreviation "Xmas" should be pronounced "Christmas" just as if the word were written out in full, rather than saying "exmas." Understanding this use of Christian symbolism might help us modern day Xians focus on more important issues of the Faith during Advent, and bring a little more Peace to the Xmas Season. >snip<
