Trinity Sunday: Missa “Benedicta sit“
Today begins the Third Cycle of the Easter Season – the Time After Pentecost, beginning with the Feast of the Blessed Trinity and is the longest of the Liturgical Year. It may comprise from twenty-four to twenty-eight weeks and differs considerably from the other liturgical seasons. In the Liturgical Year there is a historical progression, beginning in Advent with the waiting for the coming of the Messias, followed by His birth at Christmas. During the Sundays after Epiphany, the Holy Childhood is commemorated, while during Lent we are reminded of the fasting in the desert and the Passion of Our Lord. The sacred cycle is completed in the Eastertide, when we celebrate the Resurrection and Ascension of Our Lord and the Descent of the Holy Ghost upon the Apostles. In this last part of the ecclesiastical year, the Church, guided by the Holy Ghost, continues the work of the Redemption, realized during the preceding part of the Liturgical Year.
“The Holy Ghost, Whom the Father will send in My Name, He will teach you all things, and bring all things to your mind whatsoever I shall have said to you.” This last season of the Liturgical Year is filled with feasts of major importance: those of the Blessed Trinity, Corpus Christi, the Sacred Heart, the Assumption and Nativity of Our Lady, All Saints and All Souls.
The Station for Trinity Sunday is at St. Peter’s Basilica. As soon as we have celebrated the Advent of the Holy Ghost, we celebrate in song the Feast of the Holy Trinity in the office of the following Sunday. The place is well chosen, for, immediately after the descent of this Divine Spirit, began the preaching and belief, and, through Baptism, faith and confession in the Name of the Father, the Son and the Holy Ghost. (St. Rupert). The fundamental dogma to which everything in Christianity is related is that of the Holy Trinity, of Whom are all things (Epistle) and to Whom are to return all those who are baptized in Its name (Gospel). Therefore after having reminded us in turn during the Cycle of God the Father, Author of the Creation, of God the Son, Author of the Redemption, and of God the Holy Ghost, Author of our Sanctification, the Church chiefly recapitulates on this day the great mystery which calls on us to recognize and adore in God the unity of nature in the Trinity of persons (Collect).

Let us pray.

EPISTLE Romans 11: 33-36
Lesson from the Epistle of Blessed Paul the Apostle to the Romans. O the depths 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 counselor? 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.
GRADUAL Daniel 3: 55-56
Blessed art Thou, O Lord, that beholdest the depths and sittest above the Cherubim. V. Blessed art Thou, O Lord, in the firmament of heaven, and worthy of praise for ever. Alleluia, alleluia. V. (Dan. 3: 52). Blessed art Thou, O Lord, the God of our fathers, and worthy to be praised forever. Alleluia.
GOSPEL Matthew 28: 18-20
At that time Jesus said to His disciples, “If any one love Me, he will keep My word, and My Father will love him, and We will come to him and will make Our abode in him: he that loveth Me not, keepeth not My words. And the word which you have heard is not Mine: but the Father’s who sent Me. These things have I spoken to you, abiding with you. But the Paraclete, the Holy Ghost, whom the Father will send in My Name, He will teach you all things, and bring all things to your mind, whatsoever I shall have said to you. Peace I leave with you, My peace I give unto you: not as the world giveth, do I give unto you. Let not your heart be troubled, nor let it be afraid. You have heard that I said to you: I go away, and I come unto you. If you loved Me, you would indeed be glad, because I go to the Father: for the Father is greater than I. And now I have told yon’ before it come to pass: that when i shall come to pass you may believe. I will not now speak many things with you. For the prince of this world cometh, and in Me he hath not any thing. But that the world may know that I love the Father, and as the Father hath given Me commandment so do I.”

PREFACE of the 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:
