“Where is thy sting, O death? Where is thy victory, O hell? Christ has risen and thou art overthrown. Christ has risen and the demons have fallen. Christ hath risen and the angels rejoice. Christ has risen, and life reigneth. Christ has risen, and not one dead resteth in the grave. For Christ having risen from the dead became the first fruits of them that slept. To Him be glory and majesty to ages of ages. Amen.
