The Roman-rite Mass of Pope Paul VI, promulgated by the Apostolic Constitution Missale Romanum, is called the Novus Ordo Missae (New Order of Mass). It’s often shortened to Novus Ordo. Because the Mass is a Holy Sacrifice, it should be referred to as The Holy Sacrifice, The Holy Sacrifice of the Mass, Holy Mass, or the Mass. (CCC 1330).
