Canticle: Worthy Is the Lamb

The canticle Dignus est agnus, (Worthy is the Lamb) is taken from Revelation 5:12-13b, 15:3b, 19:5b-6

Worthy is the Lamb who was slain
to receive power and riches and wisdom and strength
and honor and glory and blessing.

To him who sits on the throne and to the Lamb
be blessing and honor and glory and might forever and ever.

Great and marvelous are your works, Lord God Almighty.
Just and true are your ways, King of the Nations.

Who will not fear, O Lord, and glorify your name?
For you alone are holy.

Praise our God, all you his servants
and you who fear him, small and great.

Alleluia! For the Lord our God the Almighty reigns.
Alleluia! Alleluia! Amen.

The canticle Dignus est agnus seems to have its origins in American Lutheranism in the late 19th century. It appeared in several service books beginning with the General Synod’s Church Book of 1868.

It appears on p. 122 of The Lutheran Hymnal (1941) without music. Earlier books prescribed its use as an option for the main canticle in Matins and Vespers (in place of the Te Deum or Magnificat). Later books suggested it as an alternative song of praise in the Common Service (in place of the Gloria in Excelsis).

In 2000 Years of Classic Christian Prayers, ed. Owen Collins, a similar text is given composed of several Bible verses from Revelation, attributed to Francis of Assisi (d. 1226):

Holy, holy, holy, Lord God Almighty, who was and who is and who is coming. (Revelation 4:8)

Worthy are you, our Lord and God, to receive the glory and the honor and the power, for you have created all things, and because of your will they existed and were created. (Revelation 4:11)

Worthy is the Lamb who was slain to receive power and riches and wisdom and strength and honor and glory and blessing. (Revelation 5:12)

Bless the Father, the Son and the Holy Spirit; sing praise to him and highly exalt him forever. (Song of the Three Holy Children)

Praise our God, all you his servants and you who fear him, small and great (Revelation 19:5)

Let every creature that is in heaven and on earth and under the earth and on the sea, and all that is in them say: To him who sits on the throne and to the Lamb be blessing and honor and glory and might forever and ever. (Revelation 5:13)

Glory be to the Father, and to the Son, and to the Holy Spirit.
Praise him and exalt him above all forever.
As it was in the beginning is now and will be forever.
Amen. Praise him and exalt him above all forever.

The text of this canticle has been reworked into a new canticle, This Is the Feast of Victory / Worthy Is Christ, by poet John W. Arthur. It first appeared as an anthem for choir, Festival Canticle: Worthy Is Christ with music by Richard W. Hillert, and made its first appearance in a hymnal in Lutheran Book of Worship as an alternative to the Gloria in Excelsis in the Divine Service.

Refrain:
This is the feast of victory for our God.
Alleluia, Alleluia, Alleluia.

1 Worthy is Christ, the Lamb who was slain,
whose blood set us free to be people of God. [Refrain]

2 Power, riches, wisdom and strength,
and honor, blessing and glory are his. [Refrain]

Short interlude…

3 Sing with all the people of God
and join in the hymn of all creation.

4 Blessing, honor, glory and might
be to God and the Lamb forever. Amen. [Refrain]

For the Lamb who was slain
has begun his reign. Alleluia. [Refrain]

The U. S. Book of Common Prayer (1979) has two canticles that have the same material as “Worthy is the Lamb.” 

A Song to the Lamb Dignus es
Revelation 4:11; 5:9-10, 13

Splendor and honor and kingly power *
___are yours by right, O Lord our God,
For you created everything that is, *
___and by your will they were created and have their being;
And yours by right, O Lamb that was slain, *
___for with your blood you have redeemed for God,
From every family, language, people, and nation, *
___a kingdom of priests to serve our God.
And so, to him who sits upon the throne, *
___and to Christ the Lamb,
Be worship and praise, dominion and splendor, *
___for ever and for evermore.

The Song of the Redeemed Magna et mirabilia 
Revelation 15:3-4

O ruler of the universe, Lord God,
___great deeds are they that you have done, *
___surpassing human understanding.
Your ways are ways of righteousness and truth, *
___O King of all the ages.
Who can fail to do you homage, Lord,
and sing the praises of your Name? *
___for you only are the holy One.
All nations will draw near and fall down before you, *
___because your just and holy works have been revealed.
Glory to the Father, and to the Son, and to the Holy Spirit: *
___as it was in the beginning, is now, and will be for ever. Amen.

Parts of this canticle are identical with the introit for Christ the King in the Roman rite. This is the Latin text:

Dignus est Agnus, qui occisus est, accipere virtutem, et divinitatem, et sapientiam, et fortitudinem, et honorem.
Ipsi gloria et imperium in saecula saeculorum.
Deus, judicium tuum Regi da: et justitiam tuam Filio Regis.

This canticle has been paraphrased into hymns:

• Splendor and Honor is a more recent one by Carl Daw.
• Although it seems to be a version of a Gloria, Glory Be to God the Father by Horatius Bonar contains most of the text of Dignus est agnus.
• The father of English hymnody, Isaac Watts, wrote a hymn version that predates this text being used as a canticle, Come, Let Us Join in Cheerful Songs. This appears in Evangelical Lutheran Worship as a hymn version of the Dignus in Holy Communion, Setting Ten.
• Timothy Dudley-Smith versified the Dignus as Heavenly Hosts in Ceaseless Worship.
