Æterna Christi munera,
Apostolorum gloriam,
Laudes canentes debitas
Lætis canamus mentibus.

Ecclesiarum principes,
Belli triumphales duces;
Cælestis aulæ milites,
Et vera mundi lumina.

Devota sanctorum fides,
Invicta spes credentium,
Perfecta Christi caritas,
Mundi triumphat principem.

In his paterna gloria,
In his voluntas Spiritus,
Exultat in his Filius,
Cælum repletur gaudio.

Te nunc Redemptor quæsumus,
Ut ipsorum consortio
Iungas precantes servulos
In sempiterna sæcula. Amen.

The eternal gifts of Christ, the glory of the Apostles, chanting with due praise, we sing with joyful minds. The princes of the churches, triumphant leaders in the battle, soldiers of the heavenly court, and true lights of the world. The devoted faith of the saints, Unconquered hope of those who believe, the perfect love of Christ triumphs over the prince of the world.  In these is these the Father’s glory, in these the will of the Spirit, in these the Son rejoices, heaven is filled with glory. Now, O Redeemer, we beseech you, that you join your servants praying to their company, in eternal ages. Amen. 

Lauds and Vespers: 10^th Century?

Exultet cælum láudibus,

resúltet terra gáudiis:

Apostolórum glóriam

sacra canunt sollémnia.

Vos, sæcli iusti iúdices

et vera mundi lúmina,

votis precámur córdium,

audíte preces súpplicum.

Qui cælum verbo cláuditis

serásque eius sólvitis,

nos a peccátis ómnibus

sólvite iussu, quæsumus.

Quorum præcépto súbditur

salus et languor ómnium,

sanáte ægros móribus,

nos reddéntes virtútibus,

Ut, cum iudex advénerit

Christus in fine sæculi,

nos sempitérni gáudii

fáciat esse cómpotes.

Deo sint laudes glóriæ,

qui dat nos evangélicis

per vos doctrínis ínstrui

et prósequi cæléstia. Amen.

May heaven exult with praises, earth resound with joy: holy solemnities sing the glory of the Apostles. You the just judges of the age, and true lights of the world, we pray with prayers of the heart, hear the petitions of those who entreat you. Who with a word close the doors to heaven and loosen its bars: we beseech you at your command absolve us from all our sins. By your decree ill health and the sickness of all are subdued: heal sick habits and restore us to strength of life. That when Christ the Judge will come at the end of time, he will grant us to share in everlasting joys. Praises of glory be to God, who granted that through you we be instructed in the teaching of the Gospel and attain heaven. Amen.
