I had the high blessing of being present when the Dominicans of the Eastern Province of the United States offered their first Missa Cantata according to their proper Dominican Rite at their parish in New York City, St. Vincent Ferrer. Fr. Austin Dominic Litke, O.P. offered the Mass on the traditional feast day of St. Thomas Aquinas, with the assistance of layman servers and Dominican friars from the Dominican House of Studies in Washington, DC, who chanted the propers of the Mass.
The high altar in St. Vincent Ferrer before Mass.
Father Litke and the servers process up the high altar.
The celebrant's Confiteor - notice the difference in the position of the servers in the Dominican Rite, compared to the Traditional Latin Mass.
The chanting of the Gospel.
Father James Brent, OP, gave an excellent sermon on St. Thomas Aquinas and our modern problem of secularism.
Fr. Litke incenses the high altar.
The elevation of the chalice containing the Precious Blood of Jesus Christ - instead of kneeling at the bottom of the steps and to the right, as in the "extraordinary form" of the Latin Rite, the censer and boat-bearer kneel behind the priest.
The celebrant extends his arm in a cruciform posture immediately after the consecration, but only for a short period of time.
Taken at some point after the consecration but before Communion.
The Dominican schola makes a full prostration as the made their Confiteor before Communion.
The schola receives the Blessed Sacrament.
The ablutions and the missal is brought back to the epistle side of the altar - the high altar and its reredos are absolutely stunning.
