The canticle Alleluia! Salvation and Glory (A Song of the Lamb) is used in the Roman Liturgy of the Hours in Evening Prayer on Sundays.
Alleluia!
Salvation and glory and power belong to our God, Alleluia!
for his judgments are true and just; Alleluia!
Alleluia!
Praise our God, all you his servants, Alleluia!
you who fear him, small and great. Alleluia!
Alleluia!
For the Lord our God the Almighty reigns. Alleluia!
Let us rejoice and exult and give him the glory, Alleluia!
Alleluia!
for the marriage of the Lamb has come, Alleluia!
and his Bride has made herself ready; Alleluia!
Glory be to the Father, and to the Son, and to the Holy Spirit:
as it was in the beginning, is now, and will be forever. Amen.
