This Easter date debate has been going on for centuries and has many complexities to sift and sort through in order to understand it. Easter is a movable feast, meaning it's never on the same date every year. The date is set according to the first full moon after the vernal equinox. This seems rather straightforward, right? Well, it appears there is question as to how to define "vernal equinox" and "full moon", and from where those things are observed. (Eastern Church holds that Jerusalem should be the observation point as that is where Jesus was crucified and rose again.) Then, there is the question as to whether the date for Easter should fall after Passover?
Add to the mix that the Western Church uses the Gregorian Calendar and the Eastern Church uses the Julian Calendar. OK, so it's going to take a little more than sifting and sorting ... so here's my take ...
No matter where we stand to observe the movements of our natural world, no matter where we stand on how we count days, we stand on this side of the Cross and Empty Tomb. We are Easter People. (Thank you to my friends in the Adirondacks for this new view of who we are with and in Christ!) We celebrate the Resurrection of our Lord every day. Yes, we especially remember our resurrection life in Christ on Easter Day, but let's not quibble over the specific date. Let's make every date a reason to celebrate our Risen Lord.
Alleluia? Oh, yes. He is risen indeed! Alleluia!
