According to Wikipedia (Internet Encyclopedia) "Christmas actually evolved from pagan traditions celebrating the winter solstice."
It was a long winter so they met to celebrate the sun ... they worshipped the sun.
Christmas is not mentioned in the Bible. We are not told by GOD to do any of these things the people of this world do concerning their holiday, Christmas.
At one point, God even said HE hated those solemn feasts:
Isaiah 1:13-17 Bring no more vain oblations; incense is an abomination unto ME; the new moons and sabbaths, the calling of assemblies, I cannot away with; it is iniquity, even the solemn meeting. 14 Your new moons and your appointed feasts MY soul hateth: they are a trouble unto me; I am weary to bear them. And when ye spread forth your hands, I will hide MINE eyes from you: yea, when ye make many prayers, I will not hear: your hands are full of blood. 16 Wash you, make you clean; put away the evil of your doings from before MINE eyes; cease to do evil; 17 Learn to do well; seek judgment, relieve the oppressed, judge the fatherless, plead for the widow.
Men establish so many feasts and holidays which are not appointed by God and they become idols of worship to men. Much sorrow comes through these things which are not called for by God.
In the early Christmas, it was a worship to the "sun" for the long winter was ending in the north countries.
When God commands something, how often does the world flock to do that commandment?
The vast popularity of Christmas testifies to it being something of man that he thought to be a good idea.
There is no word from God in the Bible to "celebrate" Christmas or Easter. These were ideas of man and set up by pagan men and became idols of men.
