[English]

Mighty Ruler, faithful God,
Who arrangest the successive changes in nature,
Giving bright light to the morning sun,
And burning heat at noon.

Put out the flames of strife,
And take away the heat of passion;
Grant us health of body,
And true peace of soul.

Grant this, most loving Father
And Thou, the only Son, equal to the Father
And, with the Spirit, the Paraclete,
Reigning through the ages.

Amen.

[Latin]

Rector potens verax Deus,
Qui temperas rerum vices,
Splendore mane illuminas,
Et ignibus meridiem:

Exstingue flammas litium,
Aufer calorem noxium,
Confer salutem corporum,
Veramque pacem cordium.

Praesta, Pater piisime,
Patrique compar Unice,
Cum Spiritu Paraclito
Regnans per omne saeculum.

Amen.

As prayed in the Midday Office of Sext according to the 1962 Roman Breviary.
