As I mentioned last Sunday, for this year, this Sunday is the day the Eastern Church celebrates Easter due to the different calendars (Gregorian v Julian) used to calculate the date.
So, to our Orthodox friends:
Χριστὸς ἀνέστη! Ἀληθῶς ἀνέστη!
Христос воскресе! Воистину воскресе!
Hristolu anyie! De alihea anyie!
Kristus vstal z mrtvých! Vpravdě vstal z mrtvých!
ქრისტე აღსდგა! ჭეშმარიტად აღსდგა!
Apologies to those I missed.
