Having witnessed to the light of the risen Christ at the Easter Vigil with the singing of the Exsultet, the Church proclaims on Easter Sunday that the tomb is empty in the singing of the Easter Sequence, Victimae Paschali Laudes.

We proclaim the victory of Christ over sin and death, and announce the hope of resurrection that awaits everyone who has died with Christ in the waters of Baptism (see Rom 6:3–5). We renew our commitment to a life “hidden with Christ in God” (Col 3:3) by the renewal of our baptismal promises; we cry out our Alleluias as we recall the events of that first Easter morning, and we long for the day in which “Christ [our] life will appear, [and] we too will appear with him in glory” (Col 3:4). This is the feast of victory for our God. Alleluia! Alleluia!
