Cæli Deus sanctissime

  1. Quarto die qui flámmeam
    solis rotam constítuens,
    lunæ minístras órdini
    vagos recúrsus síderum,

  2. Ut nóctibus vel lúmini
    diremptiónis términum,
    primórdiis et ménsium
    signum dares notíssimum:

  3. Illúmina cor hóminum,
    abstérge sordes méntium,
    resólve culpæ vínculum,
    evérte moles críminum.

  4. Præsta, Pater piíssime,
    Patríque compar Unice,
    cum Spíritu Paráclito
    regnans per omne sǽculum. Amen.

— Liber Hymnarius

  1. establishing on the fourth day
    the sun’s fiery wheel
    the moon’s ministries in the same line,
    the wandering ways of the stars,

  2. So that you might give a very clear sign
    of the separate ends
    of night or day
    and to the months’ beginnings,

  3. Illuminate our hearts,
    wipe away the filth in our mind,
    shatter the chains of our faults,
    overturn the calamities of our crimes.

  4. Grant this, most blessed Father,
    and Sole-Begotten, equal to the Father,
    with the Spirit Paraclete
    reigning through every age. Amen.
