Christmas (or Christ Mass) has no reality or bearing on Jesus. Christmas was illegal in the US up until about 1856. the Puritans left England to get away from England Paganism and get the holiday OUT of the church!
Christmas is the worship of numerous gods but the SAME god with different names; Chemosh, shemosh, Baal, Jupiter, sophia...
Christ-mass is the sun and tree worship. Abithaliah and Jezebel both brought it into BOTH kingdoms of Israel and GOD due to their pagan worship, sent them into the 70-year captivity. Constantine was fearful of losing his kingdom to the coming huns, Goths, Visi-Goths and Nordics who wanted to destroy the kingdom. So Constantine held the Nicene meeting in 325AD and implemented Roman Catholicism and brought the sun/tree worship into the church which most churches today celebrate.
Jeremiah 10King James Version (KJV)
10 Hear ye the word which the Lord speaketh unto you, O house of Israel:
2 Thus saith the Lord, Learn not the way of the heathen, and be not dismayed at the signs of heaven; for the heathen are dismayed at them.
3 For the customs of the people are vain: for one cutteth a tree out of the forest, the work of the hands of the workman, with the axe.
4 They deck it with silver and with gold; they fasten it with nails and with hammers, that it move not.
5 They are upright as the palm tree, but speak not: they must needs be borne, because they cannot go. Be not afraid of them; for they cannot do evil, neither also is it in them to do good.
And...as punishment, GOD sent the Jews into Babylonian captivity for their disbedience
Isaiah 49King James Version (KJV) And he said, It is a light thing that thou shouldest be my servant to raise up the tribes of Jacob, and to restore the preserved of Israel: I will also give thee for a light to the Gentiles, that thou mayest be my salvation unto the end of the earth.
GOD then enacted his plan to go after his "elect" Gentiles forming the Ekklesia, the "church" in the greek and EK means "called out" from predestination.
