Jeager, Welcome to the fray. The OP states, "Does Xmas have anything to do with Christ?"
There was no "mass" celebrated by Christians(Xtians) of pagan deities.
However, the day chosen to celebrate the Birth of Jesus Christ does have the fact that Jesus Christ was born and given a date. A "MASS" was instituted for its yearly celebration.
Many trapping have been added and HIS birth has been sharply curtailed in recent years---by disbelievers of HIM and GOD the Father.
Without Christ, the Day would be as the Godless desire---Xmas/Day of lust/winter solstice.
Satan has counterfeited many things of significance to Christian Believers.
Accept the worship of sun god's on Dec 20-25th is recorded in almost every ancient civilization. Mithra was worshipped in Persia, Horace in Egypt, Tammuz in ancient Bablyon, Yule in the Scandinavia. Are you saying that these cultures were not already doing this?
People were even setting up fir trees in houses and adorning them with gold and silver balls!!
The Bible actually speaks about this:
1Hear ye the word which the LORD speaketh unto you, O house of Israel;
2thus saith the LORD:
Learn not the way of the nations,
And be not dismayed at the signs of heaven;
For the nations are dismayed at them.
3For the customs of the peoples are vanity;
For it is but
a tree which one cutteth out of the forest,
The work of the hands of the workman with the axe.
4They deck it with silver and with gold,
They fasten it with nails and with hammers, that it move not.
5They are
like a pillar in a garden of cucumbers, and speak not;
They must needs be borne, because they cannot go.
Be not afraid of them, for they cannot do evil,
Neither is it in them to do good. Jer 10:1-5
