In the Mass of the Roman Rite and also in the Eucharist of the Anglican Communion, the Lutheran Church, and the Western Rite of the Orthodox Church the Agnus Dei is the invocation to the Lamb of God sung or recited during the fraction of the Host. The text is:

Lamb of God, you who take away the sins of the world, have mercy upon us.

Lamb of God, you who take away the sins of the world, have mercy upon us.

Lamb of God, you who take away the sins of the world, grant us peace.
