Christmas

Christmas can't be anti-Biblical, because it's not mentioned in the Bible, right? Wrong.

Actually it is mentioned in the Bible, in Jeremiah 10:2-5.

"Jeremiah 10:2-5: 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. 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. They deck it with silver and with gold; they fasten it with nails and with hammers, that it move not. 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.

This is a not particularly subtle reference to the song, "Deck the Halls", written thousands of years earlier! Christmas was an Old Testament pagan tradition where trees were chopped down, fastened with nails and hammers so they wouldn't move, decked with silver and gold, and considered a "custom." We are specifically commanded not to learn this way of the heathen.
