Easter Sunday is celebrated because for many that is the day of His resurrection. We call it Resurrection Sunday.
Now, on a personal thingy, while I accept others can do as they wish, I have some concerns with calling people brothers and sisters in Christ who do not celebrate the Birth of Christ or the Resurrection of Christ. That's just me, not my church. I wonder why such people bother to celebrate anything?
Anyway..........
May God richly bless all here in the New Year............
