EPISTLE Romans 11. 33-36
Lesson from the Epistle of Blessed Paul the Apostle to the Romans.

[The fundamental dogma of our Faith is that of the Holy Trinity.]

O 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 hath known the mind of the Lord? Or who hath been His counsellor? Or who hath first given to Him, and recompense shall be made Him? For of Him, and by Him, and in Him, are all things: to Him be glory for ever. Amen.

PREFACE
Preface of the Most Holy Trinity

Vere dignum et justum est, aequum et salutare, nos tibi semper, et ubique gratias agere: Domine sancte, Pater omnipotens, aeterne Deus. Qui cum unigenito Filio tuo, et Spiritu Sancto, unus es Deus, unus es Dominus: non in unius singularitate personae, sed in unius Trinitate substantiae. Quod enim de tua gloria, revelante te, credimus, hoc de Filio tuo, hoc de Spiritu Sancto, sine differentia discretionis sentimus. Ut in confessione verae, sempiternaeque Deitatis, et in personis proprietas, et in essentia unitas, et in majestate adoretur aequalitas. Quam laudant Angeli atque Archangeli, Cherubim quoque ac Seraphim: qui non cessant clamare quotidie, una voce dicentes: 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:

 

COMMUNION Tobias 12. 6

Benedicimus Deum coeli: et coram omnibus viventibus confitebimur ei: quia fecit nobiscum misericordiam suam. We bless the God of heaven, and before all living we will praise Him; because He has shown His mercy to us.

 

POSTCOMMUNIONS.--O Lord, our God, may the receiving of this Sacrament and the acknowledging of the holy and eternal Trinity and its undivided Unity profit us unto health of mind and body. Through our Lord Jesus Christ, Thy Son, who liveth and reigneth with Thee . . .
   We who are filled with such precious gifts, beseech Thee, O Lord, that we may obtain graces for salvation, and never cease from Thy praise. Through our Lord Jesus Christ, Thy Son, who liveth and reigneth with Thee in the unity of the Holy Ghost . . .
