"Christmas trees are pagan or secular at best."
Not really true.
Once a tradition takes on a religious significance, it doesn't really matter where it came from. Rather, it matters what value people ascribe to that symbol at the moment.
I seriously doubt you place much religious significance in the pelican, but in medieval times, it was seen as a sign of the sacrifice of Christ, to have bled from its breast to feed its young.
Sacred? Absolutely. A reflection of the divine (if not a manifestation of the essence) in the natural world.
Religious today? Not really.
You make no sense...that's exactly what newzjunky said.
