Pascha Nostrum is a hymn sometimes used by Christians during Easter season. The title is Latin for "Our Passover," and the text consists of the words of several verses of Scripture: 1 Corinthians 5:7–8, Romans 6:9–11, and 1 Corinthians 15:20–22.
The Latin text is: Pascha nostrum immolatus est Christus, alleluia: itaque epulemur in azymis sinceritatis et veritatis, alleluia, alleluia, alleluia.
After the Reformation it was preserved (in an English translation) in the Church of England's Book of Common Prayer, appointed to be said in place of the Venite at Morning Prayer on Easter Day. In some churches it may be used in place of the Gloria in Excelsis during the Easter season, especially at the Easter Vigil. It has been put to many different musical settings.
In the Catholic Church, in masses celebrated according to Divine Worship: The Missal, the first verse is said or sung responsively by the priest and congregation after the sign of peace as the priest breaks the host. It is followed by the comixture and the singing of the Agnus Dei.
Christ our Passover has been sacrificed for us;
therefore let us keep the feast,
Not with the old leaven, the leaven of malice and evil,
but with the unleavened bread of sincerity and truth. Alleluia.
Christ being raised from the dead will never die again;
death no longer has dominion over him.
The death that he died, he died to sin, once for all;
but the life he lives, he lives to God.
So also consider yourselves dead to sin,
and alive to God in Jesus Christ our Lord. Alleluia.
Christ has been raised from the dead,
the first fruits of those who have fallen asleep.
For since by a man came death,
by a man has come also the resurrection of the dead.
For as in Adam all die,
so also in Christ shall all be made alive. Alleluia.
