CONSECRATION OF A CHALICE AND PATEN
The ordinary minister of the consecration of the chalice and paten used at Mass is a bishop. In missionary countries some priests, by Apostolic indult, have the privilege of consecrating these sacred vessels. The bishops of the United States have the faculty of delegating priests for performing this rite by virtue of the Facultates Extraordinariæ, C, VI. These two altar vessels must be consecrated before they can be used at the altar. They are always consecrated at the same time, because both are indispensable at the celebration of Mass, the paten for holding the Body of Christ and the chalice for containing the Precious Blood. Chalices which were formerly used for the offerings of wine made by the faithful, for the ornamentation of the altar, and at the administration of baptism, to give to the newly baptized a symbolical beverage composed of milk and honey, were not consecrated. The same is true of the patens used at present at the Communion of the faithful to prevent consecrated Particles from falling to the floor.
Chalices and patens may be consecrated on any day of the year and at any hour, without solemnity, although in many places this rite takes place after Mass and at the altar. First the paten is consecrated, probably because it is to hold the Sacred Host, which is consecrated before the Precious Blood, and because the species of bread is always mentioned before the species of wine. The function begins with an address to the faithful, or at least to the attendants, exhorting them to implore the blessing of
God on the action the consecrator is about to perform. This is followed by a prayer that
God may render the rite efficacious, after which the consecrator anoints the paten twice with holy chrism, from rim to rim, in the form of a cross, and rubs the oils over the whole upper side of it, reciting at the same time the consercratory form. The same ceremony with a special address, prayer, and form, is performed over the chalice, except that the consecrator anoints the inside of the chalice twice from rim to rim, and rubs the oil all over the inside of the cup. The consecrator then recites a prayer in which allusion is made to the symbolical meaning of the chalice and paten, the former of which , according to
Benedict XIV (De Sacrificio Missæ, Sect. i, n 31), represents the tomb in which the body of Christ was laid, and the latter the stone with which the tomb was closed. Finally, he sprinkles both vessels with
holy water, saying nothing. It is difficult to determine when the Church began to consecrate chalices and patens. Some liturgists are of the opinion that the custom of doing so goes back to the time of
St. Sixtus I (d. 127), who, by a decree, forbade any other than those constituted in Sacred orders to touch the sacred vessels (Rom. Breviary, 16 April). Even if this decree is authentic, it would probably only prove that the prohibition was made out of respect due to the vessels which contained the Sacred Species. Other refer to a passage of St. Ambrose (d. 397) in which he says that the vasa Ecclesiæ initiata may be sold for the relief of the poor. Commentators interpret initiata to mean not consecrata, but rather usa, or vessels which had been used for the sacred mysteries. The ancient canons and decrees decide the material of which chalices and patens must be made, but they do not say a word of the consecration, although they treat the consecration of churches, altars, bishops, etc.; hence we may conclude that chalices and patens were not consecrated by a special form before the thirteenth century.
