The Right Reverend Paul Ferguson, who is the Bishop of Whitby, says he would be sad to see Holy Week no longer determind by the lunar calendar.
Northumbria's King Oswiu ruled at the Synod of Whitby in 663/664 A.D. his kingdom would follow the lead of Rome and observe Easter according to the moon.
The Archbishop of Canterbury has said he would like to see churches across the Christian spectrum unite and celebrate Easter on a fixed date.
The proposal has prompted concern in Whitby from people who fear the move could remove part of the seaside town's heritage.
Speaking earlier on Premier's News Hour programme, Rt Revd Paul Ferguson said: "The most important thing is that we think about what it's all about; the blood of Christ on Good Friday [and] Christ's victory over death on Easter Sunday.
"When we celebrate Easter actually pales in significance beside those great truths and that wonder.
"Personally, I'd be a little bit sorry if we lost the link with the lunar calendar because the date of Easter is fixed partly by the dates of the moon but, even if we do fix the date of Easter, it's going to be the result of a marvelous collaberation of Christians of all traditions who've never been able to work together in this way before.
"Even if we do loss that little bit of history, there will be a virtue out of it and something we'll be able to celebrate.
