My parents weren't JW. There is a description of a tree in chapter 10 of Jeremiah. As I recall the WT referred to these as totems. The very description fits a xmas tree: Jeremiah 10:2...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.
Anyway, my Dad thought this description meant xmas tree and when we would drive by houses with trees displayed, he would say, "A heathen lives in that house." That sound judgmental, but it was stated as fact, not judgement. He was helpful to anyone in need, so never held it against them. When I was little , we celebrated xmas and for whatever reason ( that scripture for sure, in part,) we quit having the tree and wrapped presents. Mom always cooked a big meal and we were given some money for to buy ourselves whatever we wanted towards the end of December. That was a big deal to be given $5 and taken to Ben Franklin!
