Here are the lyrics in Greek, for which the song was written:
Χριστός ανέστη εκ νεκρών,
θανάτω θάνατον πατήσας,
και τοις εν τοις μνήμασι,
ζωὴν χαρισάμενος!
Christos anesti ek nekron,
thanato thanaton patisas,
ke tis en tis mnimasin,
zoin charisamenos!
and in English:
Christ is risen from the dead,
Trampling down death by death,
And to those in the tombs
He has given life!
