How did it come about that some write X-mas instead of Christmas?
The Greek word for Christ begins with the letter chi. The capital form of the letter chi appears as an “X” in the English language. Here is the Greek word with a capital chi.
Consequently, the letter “X” has become an abbreviation for Christ, and Christmas is abbreviated as “Xmas” by the secular world.
Today, the secular world hates Christ and Christians because we believe in Christ. Therefore, they seek to eliminate Christ and silence Christians. They are intolerant of Christians. Christ had warned us that this would occur and prophesied that in the last days the entire world will hate us.
Then they will deliver you to tribulation, and will kill you, and you will be hated by all nations because of My name. Matthew 24:9 (NASB)
Let us keep Christ in Christmas and spell out the full word.
