For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. For God did not send his Son into the world to condemn the world, but to save the world through him.
The use of the term ‘Xmas’ dates back to the 16th century.
The ‘X’ in the word Xmas comes from the ancient Greek language.
In Greek, Christ begins with the letter X.
So, Xmas simply means Christmas.
