Easter is a celebration, of course, of the significant event in Christianity. The Resurrection of Jesus Christ is God’s promise of the future of Christians. For the first thousand years of Christianity, this “holiday” was most celebrated.
Of course, Buddhists do not celebrate this event. This is what Rev. Nakano said this morning.
On the other hand, the term, “Easter,” is not from the Bible, it comes from a celebration, or festival that predates Christianity as the religion spread from its origins in the
As a rite of passage of time into Spring, some of the Easter traditions came from the festival, i.e., eggs and Easter hunt, etc. As Rev. Nakano also noted today, there are differences in interpretation, that she gave several examples of it.
Since the ancient peoples kept track of time by observing the astronomical phenomenon, the ancient Easter was probably celebrated during the Spring Equinox. The Christian Easter is calendared on a more complicated astronomical formula to recreate the annual observance of the “heavens” that are associated to the original event. Which is why the date of Easter differs from year to year.
An aside, the Jewish observance of Passover is also marked astronomically with the emphasis on the lunar cycle.
Another aside, one of the calendars that was observed had a miscalculation and observances of such holidays as we know today such as Christmas begain to fall in different season, so this was corrected with the calendar in use today. Calendars are so arbitrary.
