Perhaps nothing captures the spirit of Easter more than the “Exultet,” the great Easter Proclamation composed about the fifth century and sung on Holy Saturday night in Catholic churches across 15 centuries.
The Exultet, an ecstatic hymn of praise of the risen Christ, begins with these powerful words: “Exult, let them exult, the hosts of heaven, exult, let angel ministers of God exult, let the trumpet of heaven sound aloud our mighty King’s triumph! Be glad, let earth, as glory floods her, ablaze with light from her eternal King, let all corners of the earth be glad, knowing an end to gloom and darkness.”
The stirring words of this proclamation spill over into the liturgy of the Easter season as we call to mind and celebrate the resurrection of Christ from the dead. But Easter is not simply poetry, it is one of the greatest events of history (along with the creation of the world and the Incarnation). - The Easter Proclamation and the Resurrection Season
