“To omit nothing doctrinal on so important a subject, we now come to speak of the minister of the Sacrament, a point, however, on which scarcely anyone is ignorant. The pastor then will teach, that to priests alone has been given power to consecrate and administer the Holy Eucharist. That the unvarying practice of the Church has also been, that the faithful receive the Sacrament from the hand of the priest, and that the priest communicate himself, has been explained by the Council of Trent; and the same holy Council has shown that this practice is always to be scrupulously adhered to, stamped, as it is, with the authoritative impress of Apostolic tradition, and sanctioned by the illustrious example of our Lord himself, who, with His own hands, consecrated and gave to His disciples, His most sacred body. To consult as much as possible, for the dignity of this so August a Sacrament, not only is its administration confided exclusively to the priestly order; but the Church has also, by an express law, prohibited any but those who are consecrated to religion, unless in case of necessity, to touch the sacred vessels, the linen or other immediate necessaries for consecration. Priest and people may hence learn, what piety and holiness they should possess who consecrate, administer, or receive the Holy of Holies.”
-Council of Trent, Session 13, Chapter 8
