Léctio Epístolæ beáti Pauli Apóstoli ad Romános

Rom 11:33-36.

O altitúdo divitiárum sapiéntiæ et sciéntiæ Dei: quam incomprehensibília sunt iudícia eius, et investigábiles viæ eius! Quis enim cognovit sensum Dómini? Aut quis consiliárius eius fuit? Aut quis prior dedit illi, et retribuétur ei? Quóniam ex ipso et per ipsum et in ipso sunt ómnia: ipsi glória in sǽcula. Amen.

℟. Deo grátias.

Lesson from the letter of St. Paul the Apostle to the Romans

Rom 11:33-36.

Oh, the depth of the riches of the wisdom and of the knowledge of God! How incomprehensible are His judgments and how unsearchable His ways! For Who has known the mind of the Lord, or who has been His counselor? Or who has first given to Him, that recompense should be made him? For from Him and through Him and unto Him are all things. To Him be the glory forever, amen.

℟. Thanks be to God.

Praefatio · Preface

de sanctissima Trinitate

Vere dignum et iustum est, æquum et salutáre, nos tibi semper et ubíque grátias ágere: Dómine sancte, Pater omnípotens, ætérne Deus: Qui cum unigénito Fílio tuo et Spíritu Sancto unus es Deus, unus es Dóminus: non in uníus singularitáte persónæ, sed in uníus Trinitáte substántiæ. Quod enim de tua glória, revelánte te, crédimus, hoc de Fílio tuo, hoc de Spíritu Sancto sine differéntia discretiónis sentímus. Ut in confessióne veræ sempiternǽque Deitátis, et in persónis propríetas, et in esséntia únitas, et in maiestáte adorétur æquálitas. Quam laudant Angeli atque Archángeli, Chérubim quoque ac Séraphim: qui non cessant clamáre cotídie, una voce dicéntes:

Holy Trinity

It is truly meet and just, right and for our salvation, that we should at all times, and in all places, give thanks unto Thee, O holy Lord, Father almighty, everlasting God; Who, together with Thine only-begotten Son, and the Holy Ghost, art one God, one Lord: not in the oneness of a single Person, but in the Trinity of one substance. For what we believe by Thy revelation of Thy glory, the same do we believe of Thy Son, the same of the Holy Ghost, without difference or separation. So that in confessing the true and everlasting Godhead, distinction in persons, unity in essence, and equality in majesty may be adored. Which the Angels and Archangels, the Cherubim also and Seraphim do praise: who cease not daily to cry out, with one voice saying:
