It is unclear how the adjective employed to describe a coniferous tree intended as public celebratory display became a “slap in the face” to the Christian community. It’s especially curious considering that the use of the fir tree around the winter solstice is commonly traced back to Germanic pagan traditions, not Christian ones.
The display of a Christmas tree, a nativity (or manger, or crèche) or any other “stuff” on public property is made central to the celebration of Christ’s birth. Suddenly the profound and unique Christian mystery of the Incarnation — the profound truth of Emmanuel, God with us — is reduced to a set of cultural traditions and a demand for public officials to sponsor and endorse their particular brand of celebration.
When that happens, it’s no longer clear what the difference is between a Christmas tree, a golden calf or a two-story blow-up polyurethane Frosty the Snowman.
