Sure, but it’s still giving reverence to a thing. That’s why the dictators named months after themselves, after all; so we, 2000 years later, liking it or not, would still be paying them homage.
In the case of Resurrection Sunday, everyone would know what that means, so there’s a conscious choice there to call it easter, particularly given some of the responses here.
People don’t like change. Someone comes along & challenges their worldview, and they take it as a personal attack. This is a “C of E” thread, and protestants should be of the basic belief that the Reformation brought better things. Well perhaps with the increased education and communication we have today that is unprecedented there is an opportunity for more better things. Many churches will be calling it Resurrection Sunday on Sunday, by the way.
To a Catholic mind, Pascha (to use the historical term) is a season; it refers to the Holy Week that we are in, or often the 50 days till Pentecost, and at times, just to the Sunday. I am all for using something that makes direct reference to the Resurrection, or Passover, but this innovation has to accomodate the entire season, and not just Sunday.
Interestingly, in Russian the word for Sunday — any Sunday — is already “Resurrection” (voskresenie). If you ask most traditional Christians, why do they go to church primarily on Sunday, they would say, — because Christ rose on a Sunday. Most European languages derive their word for Sunday from Kyrios/Dominus, the Lord. So “Resurrection day” can justly apply to any Sunday.
How about “Lord’s day”, “Paschal Lord’s day” and “Paschal Season”?
