On the Catholic Priesthood
Council of Trent
"If any one saith that there is not in the New Testament a visible and external priesthood; or that there is not any power of consecrating and offering the true Body and Blood of the Lord, and of forgiving and retaining sins; but only an office and bare ministry of preaching the Gospel; or that those who do not preach are not priests at all; let him be anathema."
