Iampridem §7

⁷ The priestly order, heir of such a sublime ministry, renews itself from age to age without changing. Those who are called to this order must thus follow by their sincerity of doctrine and innocence of life, in the footsteps of the first Bowers of the faith, whom Christ Himself chose. The right and duty to teach young people whom God calls to become His ministers and the dispensers of His mysteries falls to the bishops alone. The people are to take their religious training from those to whom it was said, "teach all nations." If this is so, how much greater is the obligation imposed on bishops to give the nourishment of sound doctrine as they see fit to these ministers, who will be the salt of the earth and will take the place of Jesus Christ among men? This duty is not the only one incumbent on the bishops; in addition, they must look after the welfare of the seminarians. They should initiate them quickly into the practices of a firm piety, a piety whose absence would leave them unworthy of the priesthood and incapable of fulfilling its duties.
