The Easter problems are deserved. In the earliest days of the Church, the synod (my fuzzy brain says 270 ce in Spain) declared that all efforts should be made to separate out the church from Judaism. One rule was to forbid observation of the Sabbath (non-work, etc on Saturday) and only to observe the Lord's Day (prayer on Sunday) - many had been observing both to follow both the Bible and church rules. Another was to forbid the dating of Easter from Jewish calculation of Passover. It was to be retained (along with Mardi Gras, Whitsun Wednesday, etc) as a movable from the Jewish calendar but they had to invent a whole new way to do it. I feel the Jews were smart enough to recognize a good calendar when they saw one (ie, the Babylonian calendar - that's why Jewish New Year is in the middle of the Jewish year) and I propose that the East-West church schism might never have happened if they'd just stuck with the good old, well-proven Babylonian calendar.

So the REAL issue is, is that the reason that Child #14 is called Babylon? Because you're supposed to sing it on Chinese New Year?
