A daily sung mass chanted in Latin.
After vesting with alb, amice, cincture and stole, the priest reaches up to his shoulders to receive the heavy cope from the server who helps him arrange the cope in place and latch the gold chain which holds it secure. The priests and servers line up in front of the vesting table, their eyes fixed upon the crucifix. When the small clock on the stone windowsill reads 7:45 all bow as the priest says in a low, but still audible tone, “Adjutorium nostrum in nomine Domine” (Our help is in the name of the Lord), with the servers responding, “Qui fecit Caelum et terram” (Who made Heaven and earth). They process in silence down the hall to the chapel, pausing at the door. With a nod from the priest, the thurifer sounds a large bell with a small wooden mallet. Mass has begun.
Upon hearing the bell, the monks in the chapel rise, arrayed either side of the choir, their woolen cream mantles contrasting with the dark brown habit. The schola, the monks whose task it is to chant the Mass, stand inside the choir stalls, waiting silently as the priest and servers process before the altar.
The thurifer snaps his fingers and all kneel at the footpace. The acolytes kneeling either side of the priest hold the Rituale, a small leather book—the pages worn with time—open as the priest intones the Veni Sancte Spiritus prayer. The schola and the rest of the monks in the choir add their voices to the priests, as all in the chapel pray for the Holy Ghost to come into their souls and prepare them for worshiping God in the sacred liturgy.
The cantors in the schola intonate the Introit from the large chorales they hold in their hands. The introit, or beginning of Mass changes based on the feast, and is repeated. While the choir chants, the priest continues with Mass in a low voice, praying from the missal, then incensing the altar, then chanting the prayer for the saint of the day.
Mass continues and the Sanctus bells fill the chapel with their silvery tone. As all kneel for the consecration, the light streaming through the window illuminates the incense rising from the thurible. The chapel is completely silent as the priest pronounces the words of consecration. After the priest consecrates the host, the bells ring out, the thurible swings and all bow their head in silent adoration.
After receiving Holy Communion each monk kneels in silence, greeting the Divine Guest and thanking Him for His condescension in coming to them each day. With the sound of the key locking the tabernacle door, all rise, and the schola chants the Communion, normally a short, pleasant chant that varies according to the Mass of the day.
After the final blessing the priest and servers kneel at the footpace and the priest solemnly intones the Salve Regina, which is prayed as part of every Mass in the Carmelite Rite. After the Salve, and the last Gospel, the priest and servers process back to the sacristy, the priest raising his hood for the procession back. The sacristans cover the altar and extinguish the candles, and all return to their place in choir for one of the most precious moments of the day; a silent thanksgiving after receiving the Lord in Holy Communion. After the time for thanksgiving there is a knock in the choir. It is time to process down to the Refectory and begin the day's work.
