Christ Is Risen! Truly He Is Risen!
Χριστὸς ἀνέστη! Ἀληθῶς ἀνέστη!

“It is the day of Resurrection; let us be radiant for the festival, and let us embrace one another. Let us say, O brethren, even to those that hate us: Let us forgive all things on the Resurrection; and thus let us cry: Christ is risen from the dead, by death He has trampled down death, and on those in the tombs He has bestowed life.”
(Doxastikon of Great and Holy Pascha)
