A saeculi strepitu segregati

Many years ago, while searching out the treasures of my missal, I discovered, among the Masses for Certain Places, the Mass of Our Lady of the Cenacle for the Saturday within the Octave of the Ascension. The proper texts of the Mass stirred my heart. It was not retained in the Collection of Masses in Honour of the Blessed Virgin Mary. The orations are, like so many composed in the 19th century, addressed to Our Lord Jesus Christ, rather than to the Father.
Collect
Deus, qui beatam Mariam semper Virginem matrem tuam
in Cenaculi solitudine cum discipulis orantem
Sancti Spiritus donis cumulasti:
fac nos, quaesumus, cordis recessum diligere;
ut sic rectius orantes
Spiritus Sancti gratiis repleri mereamur.
O God, who with the gifts of the Holy Spirit
didst fill the Blessed Ever–Virgin Mary, Thy mother,
in prayer with the disciples in the solitude of the Cenacle;
grant that we may cherish the secret places of the heart,
so that by a more insistent prayer,
we may deserve to be filled with the graces of the Holy Spirit.

Secret or Prayer Over the Oblations
Haec sacra, Domine, tibi in honorem beatae Mariae Virginis Matris tuae litantes.
humiliter petimus,
ut sicut ipsa verba tua sancta in corde suo sollicite servavit,
nobis quoque ejus intercessione concedas,
ita in lege tua assidue meditari,
ut fidelius opere implere eam valeamus.
Offering Thee, O Lord,
these sacred gifts in honour of the Blessed Virgin Mary Thy mother,
we humbly ask that,
by the example and intercession of her
who carefully kept Thy holy words in her heart,
we too may meditate Thy law assiduously,
so as to put it into practice more faithfully.

Postcommunion
Deus, qui fideles tuos in Cenaculi recessu cum Maria Matre tua sacratissima
perseverantes et unanimes in oratione effecisti:
praesta, quaesumus;
ut his quoque donis ornati et a saeculi strepitu segregati,
tibi soli in caritate perfecta vivamus.
O God, who to thy faithful withdrawn in the Cenacle,
didst grant to perseverance in prayer in oneness of heart
with Mary, Thy most holy Mother,
grant, we beseech Thee, that we also,
graced with the same gift
and separated from the noise of the world,
may live for Thee alone in perfect charity.
