I'm surprised no one googled
"where did Xmas come from".
According to this article... It came from the Emperor Constantine who was a convert. It's the Greek letter "Chi".
In another
article I found this.
#But it turns out that "Xmas"# isn't a modern convention at all. It was used commonly in 16th-century Europe, when many people began using the term "Christos," the Greek translation for Christ, to refer to Jesus. The letter chi in the Greek alphabet is symbolized by an X and translates to "ch." So along with the Greek letter rho for "r", the term Xmas was used to refer to the birth of Jesus as an informed abbreviation, not an offensive one. Xmas was a way for Christian scholars to refer to Jesus respectfully in an ancient language -- not to disrespect his name with a harsh symbol. In fact, variations of "Xmas" date back to 1021 [source: BBC.com].
Now neither of these sources are my regular places to ask these questions. But hey.... they both take the hatefulness out of the argument for taking the name Christ out of Christmas, so I guess I'm good with it....
I'm still not going to use the X myself....
