Rector potens, verax Deus

1 min

O God of truth, O Lord of might,

Who orderest time and change aright,

Who send'st the early morning ray,

And light'st the glow of perfect day:

Extinguish thou each sinful fire,

And banish every ill desire;

And while thou keep'st the body whole,

Shed forth thy peace upon the soul.

Almighty Father, hear our cry,

Through Jesus Christ, our Lord most High,

Who, with the Holy Ghost and thee,

Doth live and reign eternally.

Amen.

Rector potens, verax Deus,

Qui témperas rerum vices,

Splendóre mane illúminas,

Et ígnibus merídiem:

Exstíngue flammas lítium,

Aufer calórem nóxium,

Confer salútem córporum,

Verámque pacem córdium.

Praesta, Pater piíssime,

Patríque compar Únice,

Cum Spíritu Paráclito

Regnans per omne saéculum.

Amen.
