Today is the Octave of Easter, also known as Low Sunday, also known as Quasimodo Sunday, also known as Dominica in albis deponendis, in Western Christendom. Most of Eastern Christendom, on the other hand, celebrate Easter today.
Χριστός ἀνέστη! Ἀληθῶς ἀνέστη!
Christ is risen from the dead,
trampling down death by death,
and to those in the tombs,
granting life.
—
Christus resurrexit a mortuis,
morte mortem calcavit,
et euntibus in sepulchris
vitam donavit.
—
المسيح قام من بين الأموات
ووطئ الموت بالموت
ووهب الحياة للذين في القبور
—
Χριστός ανέστη εκ νεκρών,
θανάτω θάνατον πατήσας,
και τοις εν τοις μνήμασι
ζωήν χαρισάμενος.
Ut in omnibus laudetur Dominus.
