I am always amazed how ignorant many Christians are about the origin of their own holidays.

Of course, if they were better informed, they would know that their beliefs are simply superstition.

"So, eventually Christianity came to an accommodation with the pagan Spring festival. Although we see no celebration of Easter in the New Testament, early church fathers celebrated it, and today many churches are offering "sunrise services" at Easter – an obvious pagan solar celebration. The date of Easter is not fixed, but instead is governed by the phases of the moon – how pagan is that?"
