1. Christmas is not the day on which Yeshua the Messiah (Jesus Christ) was born. He was likely born in the autumn during the biblical Feast of Tabernacles. In ancient times, December 25 was considered the birthday of the demon-sun god by many heathen religions. This was definitely not the birthday of Yeshua!
2. There’s no biblical command to celebrate Christmas.
3. Christmas has become a pagan substitution for YHVH’s true biblical holidays or festivals, which are listed in Leviticus 23. These are the same biblical festivals that Yeshua and his apostles celebrated. They never celebrated the Messiah’s birth.
4. Christmas is the Christianization of various ancient pagan sun god, sex-worship rituals having to do with the winter solstice. “Cleaning up” a pagan custom is contrary to the biblical truth of turning away from the practices of the heathen and having nothing to do with them after one chooses to follow Elohim and his Word as found in the Bible.
5. Christmas is laced with heathen and Satanic rituals and traditions. These are things the saints should have nothing to do with!
6. The Bible forbids placing any trees or tree-like objects near an altar (or in a church building), since this is a heathen practice (Deut 16:21).  Most Christians violate this command when they place Christmas trees in their church sanctuaries near their altars every year at Christmas.
7. The Bible forbids the heathen practice of incorporating trees into any religious service (Deut 12:1–4). Elohim hates pagan religious practices that happen under trees (Isa 57:5; Jer 3:6).
8. Celebrating Christmas is friendship with the world which is an act of hatred toward Elohim. In this area, it makes one a friend of the world and an enemy of Elohim (Jas 4:4).
9. Elohim condemns, forbids and calls an abomination bringing any pagan items into our houses (Deut 7:24–26), of which Christmas trees and nearly all Christmas’ associated accoutrements, paraphernalia and traditions are associated.
10. The Bible commands the saints not to put up anything that even remotely resembles a Christmas tree. Jeremiah 10:1–5 is almost a perfect description of a modern Christmas tree — and it was a pagan custom 1000 years before Christmas became a Christian holiday in the Catholic Church.
11. Christmas perpetuates the lie of Santa Clause to one’s children. Lying is not a value one wants to pass on to their children. Lying is a violation of the ninth of YHVH’s ten commandments and is a sin.
12. The Bible commands the saints not to learn or practice the ways of the heathens (Jer 10:2; Lev 18:3; 20:23).
13. Christmas is about syncretizing biblical truth (i.e., the birth of Yeshua) with pagan and satanic customs. In the Bible, YHVH commands his people not to be like the heathens, turn from evil, and don’t learn their evil customs. Yeshua commanded his disciples to be in the world, but not to practice its evil ways (John 17:11, 14). Christmas is practicing the evil ways of the heathens.
14. For many, the main focus of Christmas is on self (“What gifts am I getting?”), rather than on Elohim’s gift to mankind, which was Yeshua the Messiah (who wasn’t even born in December). Christmas generally promotes a culture of selfishness and self-centeredness. These are values that were antithetical to everything that Yeshua and his disciples lived and taught.
15. Christmas promotes an atmosphere of greed, covetousness and materialism. 
16. Christmas is a tradition started by the Catholic Church, and I’m not a Catholic and I don’t take my spiritual marching orders from any pope —  especially when he tells me to do something contrary to the Bible, the Word of Elohim.
17. Christmas is a short, one day long holiday. Too much emphasis is placed on this one day. The devil has tricked and shortchanged Christians into substituting Christian holidays like Christmas for the biblical ones. YHVH gives his saints seven biblical holidays with two of them lasting for seven days each (see Lev 23). These biblical holidays are called feasts, and they are spiritual and guilt-free celebrations focusing on rejoicing and righteously partying with family, friends and Elohim around godly and biblical themes all involving the gospel’s plan of redemption. They are totally righteous with no paganism mixed in. This can’t be said about Christmas.
18. Do your homework. You will find that even the phrase “Ho, ho, ho, merry Christmas” is sacrilegious and blasphemous.
19. If Christmas day turns sour for people (e.g., because of bad family experiences and unfulfilled expectations), then one’s year is ruined until next Christmas when one gets another shot at it in hopes it’ll be better the next go around. How pitifully sad!
20. Christmas as celebrated by the majority of people ends up taking the focus off the glorious event of the Savior’s birth, trivializes it and then places the emphasis on gift-giving, partying and mindless unbiblical pagan traditions and rituals.
21. The Bible commands us to abstain from all appearances of evil (1 Thess 5:22). There is much evil, Satanic and idolatrous baggage associated with Christmas; therefore, those who are serious about their biblical walk of righteousness and want to be obedient to YHVH Elohim should not be going near it.
22. Those who celebrate Christmas in the traditional way are honoring or worshipping pagan deities. Anytime anyone puts a pagan practice or tradition ahead of obedience to Elohim and his Word, this is, by biblical definition, idolatry. Whether it’s Christmas lights on the house, wreaths, evergreen foliage, mistletoe, the Christmas tree with its red balls, gifts under the tree, Santa Clause, or even the Christmas greeting of “Ho, ho, ho, merry Christmas,” it all originates from ancient Satanic, idolatrous and lewd sex worship practices originating from pagan religions. This is not something with which the true saints of YHVH Elohim wants to be involved.
23. Christmas puts a lot of people into financial debt. Debt is bondage and evil.
24. Christmas was become a major money-making venture for merchants, and I refuse to be suckered in by their marketing schemes to purchase their products.
25. Celebrating Christmas is following a multitude to do evil — something YHVH forbids (Exod 23:2).

Now that you have received the light of the truth about Christmas, you are responsible before Elohim to live up to that truth. Will you put obedience to the Word of Elohim and his truth first in our life, or continue to walk in sin? To obey Elohim means to cast out of your life all idolatrous practices and cease doing that which is evil and sinful. This is then followed by choosing to obey YHVH Elohim in Spirit and in truth (John 4:23–24). “Therefore to him that knoweth to do good, and doeth it not, to him it is sin” (Jas 4:17).

Come out of [Mystery Babylon the Great], my people, lest you share in her sins, and lest you receive of her plagues. For her sins have reached to heaven, and Elohim has remembered her iniquities. (Rev 18:4–5)

And what agreement has the temple of Elohim with idols? For you are the temple of the living Elohim. As Elohim has said: “I will dwell in them And walk among them. I will be their Elohim, And they shall be My people. Therefore “Come out from among them and be separate,” says Adonai. “Do not touch what is unclean,  and I will receive you.” (2 Cor 6:16–17)
