Chapter 17 — Part II: The Sacraments — Confirmation

Section 18. The necessity of this consecration may, however, be shown from reason also. In most of the other Sacraments Christ so instituted their matter as to impart holiness also to it. For not only did He designate water as the element of Baptism, saying: Except a man be born again of water and the Holy Ghost, he cannot enter the kingdom of God; but He also, at His own Baptism, imparted to it the power of sanctifying thereafter. Hence these words of St. Chrysostom: The water of Baptism, had it not been sanctified by contact with the body of our Lord, could not purge away the sins of believers. As, then, our Lord did not consecrate this matter of Confirmation by actually using and handling it, it is necessary that it be consecrated by holy and religious prayers; and this consecration can appertain to none save the Bishop, who has been appointed the ordinary minister of this Sacrament.
