All meaningless, irrelevant obfuscation. The fact that one thing is similar to another thing does NOT prove derivation. You have failed, and always will fail, to provide even one sliver of credible, verifiable, historical evidence that anything about the Christian observance of the birth of Christ was taken from any pagan practice. Wreaths, trees, mistletoe etc. are all irrelevant. They are not part of the Christian observance. Christians are not responsible for how non-Christians decorate at Christmas or any other time. And just for your info your out-of-context proof text has nothing to do with decorated trees which did not exist and which nobody worshiped.
Jeremiah 10:3-5
(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.
The anti-Christmas crowd quote this passage out-of-context pretending that it is referring to decorated trees. Decorated trees are not expected to speak, pagan deities are. Decorated trees do not move, pagan deities are expected to. Decorated trees do not do anything, good or evil, pagan deities are expected to do things for their followers. Now let us read the rest of the passage which the anti-Christmas crowd ignores.
Jeremiah 10:8-9
(8) But they are altogether brutish and foolish: the stock is a doctrine of vanities.
(9) Silver spread into plates is brought from Tarshish, and gold from Uphaz, the work of the workman, and of the hands of the founder: blue and purple is their clothing: they are all the work of cunning men.
Jeremiah 10:11
(11) Thus shall ye say unto them, The gods that have not made the heavens and the earth, even they shall perish from the earth, and from under these heavens.
The poor people who cannot afford an idol made completely of gold or silver, cut down a tree have it carved into their idol then cover it with silver or gold plates. Decorated trees don’t have robes of blue and purple, kings and idols do. Now let’s read the parallel passage in Isaiah who was a contemporary of Jeremiah
Isaiah 40:19-20
(19) The workman melteth a graven image, and the goldsmith spreadeth it over with gold, and casteth silver chains.
(20) He that is so impoverished that he hath no oblation chooseth a tree that will not rot; he seeketh unto him a cunning workman to prepare a graven image, that shall not be moved.
Isaiah 44:13-17
(13) The carpenter stretcheth out his rule; he marketh it out with a line; he fitteth it with planes, and he marketh it out with the compass, and maketh it after the figure of a man, according to the beauty of a man; that it may remain in the house.
(14) He heweth him down cedars, and taketh the cypress and the oak, which he strengtheneth for himself among the trees of the forest: he planteth an ash, and the rain doth nourish it.
(15) Then shall it be for a man to burn: for he will take thereof, and warm himself; yea, he kindleth it, and baketh bread; yea, he maketh a god, and worshippeth it; he maketh it a graven image, and falleth down thereto.
(16) He burneth part thereof in the fire; with part thereof he eateth flesh; he roasteth roast, and is satisfied: yea, he warmeth himself, and saith, Aha, I am warm, I have seen the fire:
(17) And the residue thereof he maketh a god, even his graven image: he falleth down unto it, and worshippeth it, and prayeth unto it, and saith, Deliver me; for thou art my god.
There is no record in the OT of any pagan people worshipping decorated trees but they did worship graven images, idols made in the image of men or beasts.
