Chapter 21 — Part II: The Sacraments — Holy Orders
Section 68. From (what we shall lay down concerning the dispositions requisite for the priesthood) it will be easy to determine what ought to be observed in conferring the other orders, due account being taken of the office and dignity of each. Now the extreme caution I hat should be used in conferring this Sacrament is gathered from the fact that, while all the other Sacraments impart grace to the recipient for his own use and sanctification, he, on the other hand, who receives Holy Orders is made partaker of heavenly grace precisely that by his ministry he may promote the welfare of the Church and therefore of all mankind.
