I have always enjoyed Christmas Eve. When I was a child we would go to midnight Mass which was a ritual to put all rituals to shame. The full blown Latin High Mass took a couple of hours and the music for Christmas would knock your socks off. Add candles and incense and a pipe organ and it was like being transported in time. It was disorienting to go back outside.
I grew up with a love of ritual, that was probably the easiest part of the leap from Catholicism to Paganism, both consider the gods worthy of a good ritual in their name.
Christmas Eve has always seemed quiet and peaceful to me. I gave up hysterical shopping, wrapping and stressing years ago, actually about the time it started being stressful instead of fun.
This year we have Solstice, Christmas and the New Moon all within a week. That's a lot of energy no matter how you label it and I have a feeling that this is an important time to work some magick.
