I have no idea why I was pinged...though I must say I completely disagree that a Christmas tree is ‘patent idolatry,’ it’s manifestly absurd, since I’ve never heard of anyone worshipping their tree, or giving it offerings, or anything of the kind as you suggest.
I can see both sides. I believe that the Christmasteers have good intentions with their tradition but I wouldn't question the faith and discipline of those that choose not to take such liberties.
