The mass, in ordinary language, is the greatest and most august of the ceremonies of the Church. Different names are given to it, according to the rites practised in the various countries where it is celebrated; as the Mozarabian or Gothic mass, the Greek mass, the Latin mass. Durandus and Eckius call those masses dry, in which no consecration is made, as that which is appointed to be said in particular by aspirants to the priesthood; and Cardinal Bona relates, on the authority of William of Nangis, that St. Louis, in his voyage abroad, had it said in this manner, lest the motion of the vessel should spill the consecrated wine. He also quoted Génébrard, who says that he assisted at Turin, in 1587, at a similar mass, celebrated in a church, but after dinner and very late, for the funeral of a person of rank.

Pierre le Chantre also speaks of the two-fold, three-fold, and even four-fold mass, in which the priest celebrated the mass of the day or the feast, as far as the offertory, then began a second, third, and sometimes a fourth, as far as the same place; after which he said as many secretas as he had begun masses; he recited the canon only once for the whole; and at the end he added as many collects as he had joined together masses.

It was not until about the close of the fourth century that the word "mass" began to signify the celebration of the eucharist. The learned Beatus Rhenanus, in his notes on Tertullian, observes, that St. Ambrose consecrated this popular expression, "missa," taken from the sending out of the catechumens, after the reading of the gospel.

In the "Apostolical Constitutions," we find a liturgy in the name of St. James, by which it appears, that instead of invoking the saints in the canon of the mass, the primitive Church prayed for them. "We also offer to Thee, O Lord," said the celebrator, "this bread and this chalice for all the saints that have been pleasing in Thy sight from the beginning of ages: for the patriarchs, the prophets, the just, the apostles, the martyrs, the confessors, bishops, priests, deacons, subdeacons, readers, chanters, virgins, widows, laymen, and all whose names are known unto Thee." But St. Cyril of Jerusalem, who lived in the fourth century, substituted this explanation: "After which," says he, "we commemorate those who die before us, and first the patriarchs, apostles, and martyrs, that God may receive our prayers through their intercession." This proves—as will be said in the article on "Relics"—that the worship of the saints was then beginning to be introduced into the Church.

Noel Alexander cites acts of St. Andrew, in which that apostle is made to say: "I offer up every day, on the altar of the only true God, not the flesh of bulls, nor the blood of goats, but the unspotted lamb, which still remains living and entire after it is sacrificed, and all the faithful eat of its flesh"; but this learned Dominican acknowledges that this piece was unknown until the eighth century. The first who cited it was Ætherius, bishop of Osma in Spain, who wrote against Ælipard in 788.

Abdias relates that St. John, being warned by the Lord of the termination of his career, prepared for death and recommended his Church to God. He then had bread brought to him, which he took, and lifting up his hands to heaven, blessed it, broke it, and distributed it among those who were present, saying: "Let my portion be yours, and let yours be mine." This manner of celebrating the eucharist—which means thanksgiving—is more conformable to the institution of that ceremony.

St. Luke indeed informs us, that Jesus, after distributing bread and wine among his apostles, who were supping with him, said to them: "Do this in memory of me." St. Matthew and St. Mark say, moreover, that Jesus sang a hymn. St. John, who in his gospel mentions neither the distribution of the bread and wine, nor the hymn, speaks of the latter at great length in his Acts, of which we give the text, as quoted by the Second Council of Nice:
