Caeli Deus sanctissime,
qui lucidum centrum poli
candore pingis igneo
augens decori lumine.
Quarto die qui flammeam
solis rotam constituens,
lunae ministras ordini,
vagos recursus siderum,
Ut noctibus, vel lumini
diremptionis terminum,
primordiis et mensium
signum dares notissimum:
Illumina cor hominum,
absterge sordes mentium,
resolve culpae vinculum,
everte moles criminum.
Praesta, Pater piissime,
Patrique compar Unice,
cum Spiritu Paraclito
regnans per omne saeculum. Amen.
Most holy God of heaven high,
Who made the circle of the sky,
You paint it now with burning light,
To make it fairer still and bright;
Who, on the fourth day, set aflame
The sun’s great wheel, and rule the same,
The phases of the moon you guide,
And stars that wander far and wide,
To give a line dividing night
From day, dividing dark from light:
A sign well-known to sight and sense,
To mark the months as they commence.
Illuminate the hearts of men,
Their unclean minds make pure again.
Untie the chains of guilt within,
Cast down the heaped-up hills of sin.
Grant it, dear Father, ever one
With Christ our Lord, your only Son,
And with the Spirit equally,
Ruling for all eternity. Amen.
