Gaudeamus omnes in Domino , diem festum celebrantes sub honore beate Mariae Virginis: de cujus Assumptione gaudent Angeli et collaudant Filium Dei. (Introit)
The great feast of the Assumption is a Double of the First Class with Octave. The feast also appears as the Dormition of the Mother of God in some earlier MSS and is known by that name in the East to this day. The liturgical colour of the feast is white.
At Mattins the invitatory, Venite, adoremus Regem regum, Cujus hodie ad aethereum Virgo Mater assumpta est in caelum, is proper to the feast. The hymn is Quem terra, pontus, sidera. In the first nocturn the antiphons Exaltata est etc are sung with psalms 8, 18 & 23. The lessons in the first nocturn, since the time of Pius V, are taken from the Incipit of the Canticle of Canticles, are particularly rich with vibrant, sensual, imagery:
Let him kiss me with the kiss of his mouth: for thy breasts are better than wine, smelling sweet of the best ointments. Thy name is as oil poured out: therefore young maidens have loved thee. Draw me: we will run after thee to the odour of thy ointments. The king hath brought me into his storerooms: we will be glad and rejoice in thee, remembering thy breasts more than wine: the righteous love thee. I am black but beautiful, O ye daughters of Jerusalem, as the tents of Cedar, as the curtains of Solomon.(1st lesson)
In the second nocturn the antiphons Specie tua etc are sung with psalms 44, 45 & 86. The lessons are from St. John Damascene's second discourse on the Dormition of the Virgin and again both exquisite and highly appropriate to the day:
"This day the holy and animated ark of the living God, she who conceived in her womb her Creator rests in the temple of the Lord, which was not made with hands. And her ancestor David leaps, and with him the Angels lead the dance, the Archangels make celebration, the Virtues ascribe glory, the Principalities exult, the Powers rejoice together, the Dominations are joyful, the Thrones keep holiday, the Cherubim utter praise, the Seraphim proclaim her glory. This day the Eden of the new Adam receives the living Paradise, wherein the condemnation was made void, wherein the tree of life was planted, wherein our nakedness was covered." (4th lesson)
In the third nocturn the antiphons Gaude, Maria virgo etc are sung with psalms 95, 96 & 97. The homily on the Gospel fragment is from St. Augustine's 27th Sermon on the Words of the Lord. The Te Deum is sung. At Lauds the antiphons Assumpta est Maria etc are sung with psalms 92, 99, 62, Benedicite and 148. The hymn O gloriosa virginum. The collect of the feast is one of the most sublime ever written:
Famulorum tuorum, quaesumus, Domine, delictis ignosce: ut, qui tibi placere de actibus nostris non valemus; Genitricis Filii tui, Domini nostri, intercessione salvemur.
Forgive, O Lord, we beseech thee, the sins of thy servants: that we who by our own deeds are unable to please thee, may be saved by the intercession of the Mother of thy Son our Lord.
At Prime and the Hours the hymns are sung with the proper Doxology and tone. In the short responsory Qui natus es de Virgine is sung, both today and throughout the Octave, and the lectio brevis is In plateis.
Mass is celebrated after Terce. The Rituale gives a Blessing of Herbs for this day which takes place immediately before Mass with Psalm 64, a series of versicles and responses, three collects, whose florid style, reminiscent of those for the Blessing of Palms, suggests a Gallican origin. The Mass formulary, Gaudeamus, is a particularly beautiful set of texts. The Gloria is sung. The Epistle is a sublime cento from the Book of Wisdom that also forms the chapters at the Office. The gradual Propter veritatem is very ancient. The Credo is sung and the preface is of the BVM, Et te in Assumptione.
In the afternoon at second Vespers all is as at first Vespers except the antiphon on the Magnificat which today is Hodie Maria Virgo caelos ascendit: gaudete, quia cum Christo regnat in aeternum. After the collect a commemoration is sung of the following feast of St. Joachim, father of the BVM. At Compline the Sunday psalms are sung and Te lucis is sung with the proper Doxology and tone.
Perhaps the most famous polyphonic setting of Ave Maris stella is that by Monteverdi from his 1610 Vespers of the Blessed Virgin:
The 'the liturgical books of 1962' have seen considerable revision of the once beautiful feast with changes both in 1960 and, previously, with the introduction of novel texts in the 1950s. Vespers gets a new chapter, hymn and collect. The new collect was once admirably described by the erudite Fr. John Hunwicke as "a modern composition which I would describe as a dollop of dogma followed by a platitude". At Mattins in the first nocturn the first lesson is taken from Genesis and then, curiously, the second and third from the former Epistle of St. Paul to the Corinthians. In the second nocturn the magnificent writings of St. Damascene are shortened by the inclusion of a sixth lesson from Pius XII's verbiage. The third nocturn has a homily of St. Peter Canisus on the new gospel pericope introduced in 1950. At Lauds there is a new chapter, a pedestrian and ugly hymn replacing O gloriosa virginum, and new collect. At Prime the lectio brevis is Dominus autem dirigat, of the season. At Prime and the Hours the tone of the hymns is that for greater feasts, not the Incarnation and the special Doxology is omitted. The 1950 mass is again banal and ugly compared with the ancient texts. At Vespers there is no commemoration of St. Joachim. The Octave was abolished in 1955.
