What is the origin of the Christmas tree and is it accepted in all Christian traditions? What is the origin of the Christmas tree and is it accepted in all Christian traditions?  

I'm certainly not aware of a "Christmas" tree appearing in the Christmas story, so I'm curious when it was associated with the holiday.
The origin of the Christmas tree is very well documented elsewhere, including Wikipedia.

There are some Christians that disapprove of the use of a Christmas tree (one reason documented also at wikipedia, and further discussed (with rebuttal) here).

There are some groups that do not use Christmas trees, for various reasons.


Some Amish do not use Christmas trees (although others do)
Although not considered "Christian" by many, Jehovah's Witnesses do not celebrate Christmas at all
Many other Evangelical groups reject some or all Christmas celebrations, on the grounds that it was originally a pagan holiday (Larger discussion on this matter here).
