No, that doesn't tell us anything about Easter celebrations! Did He say don't Remember my Resurrection?
Why do you think He wants us to REMEMBER His death? His Blood and His broken Body?
Because of the sacrifice He endured for us!
You're injecting and adding your own belief about Easter into Luke 22:19.
That's called extrapolation.
I am following exactly what Jesus stated in the Bible..."keep doing this in remembrance of me"...speaking of his last meal with his apostles, consisting of bread and wine, on Nisan 14 33 CE...are you?
