Question: where in the bible does it say not to put up a christmas tree?
Answer: 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.
