I'd suggest you read the book Pagan Christianity by Frank Viola and George Barna. A great many Pagan influences and rituals were infused into Christianity during the time of Constantine in the Roman Empire. Most Christians engage in Pagan practices without even knowing it, and celebrate the Pagan holidays. Most Christians are oblivious to the origins of their practices or how much the Bible and doctrines of Jesus have been doctored to support an elite power structure without their best interests at heart. Personally I find this amusing.

Here's a link to the book on Barnes and Noble:
