Council of Trent: Session 23
Being the seventh under the Sovereign Pontiff, Pius IV., celebrated on the fifteenth day of July, MDLXIII.
THE TRUE AND CATHOLIC DOCTRINE, TOUCHING THE SACRAMENT OF ORDER, DECREED AND PUBLISHED BY THE HOLY SYNOD OF TRENT, IN THE SEVENTH SESSION, IN CONDEMNATION OF THE ERRORS OF OUR TIME.
Chapter 1
On the institution of the Priesthood of the New Law.
Sacrifice and priesthood are, by the ordinance of God, in such wise conjoined, as that both have existed in every law. Whereas, therefore, in the New Testament, the Catholic Church has received, from the institution of Christ, the holy visible sacrifice of the Eucharist; it must needs also be confessed, that there is, in that Church, a new, visible, and external priesthood, into which the old has been translated. And the sacred Scriptures show, and the tradition of the Catholic Church has always taught, that this priesthood was instituted by the same Lord our Saviour, and that to the apostles, and their successors in the priesthood, was the power delivered of consecrating, offering, and administering His Body and Blood, as also of forgiving and of retaining sins.
Chapter 2
On the Seven Orders.
And whereas the ministry of so holy a priesthood is a divine thing; to the end that it might be exercised in a more worthy manner, and with greater veneration, it was suitable that, in the most well-ordered settlement of the church, there should be several and diverse orders of ministers, to minister to the priesthood, by virtue of their office; orders so distributed as that those already marked with the clerical tonsure should ascend through the lesser to the greater orders. For the sacred Scriptures make open mention not only of priests, but also of deacons; and teach, in words the most weighty, what things are especially to be attended to in the Ordination thereof; and, from the very beginning of the church, the names of the following orders, and the ministrations proper to each one of them, are known to have been in use; to wit those of subdeacon, acolyth, exorcist, lector, and door-keeper; though these were not of equal rank: for the subdeaconship is classed amongst the greater orders by the Fathers and sacred Councils, wherein also we very often read of the other inferior orders.
Chapter 3
That Order is truly and properly a Sacrament.
Whereas, by the testimony of Scripture, by Apostolic tradition, and the unanimous consent of the Fathers, it is clear that grace is conferred by sacred ordination, which is performed by words and outward signs, no one ought to doubt that Order is truly and properly one of the seven sacraments of holy Church. For the apostle says; I admonish thee that thou stir up the grace of God, which is in thee by the imposition of my hands. For God has not given us the spirit of fear, but of power and of love of sobriety.
Chapter 4
On the Ecclesiastical hierarchy, and on Ordination.
But, forasmuch as in the sacrament of Order, as also in Baptism and Confirmation, a character is imprinted, which can neither be effaced nor taken away; the holy Synod with reason condemns the opinion of those, who assert that the priests of the New Testament have only a temporary power; and that those who have once been rightly ordained, can again become laymen, if they do not exercise the ministry of the word of God. And if any one affirm, that all Christians indiscriminately are priests of the New Testament, or that they are all mutually endowed with an equal spiritual power, he clearly does nothing but confound the ecclesiastical hierarchy, which is as an army set in array; as if, contrary to the doctrine of blessed Paul, all were apostles, all prophets, all evangelists, all pastors, all doctors. Wherefore, the holy Synod declares that, besides the other ecclesiastical degrees, bishops, who have succeeded to the place of the apostles, principally belong to this hierarchical order; that they are placed, as the same apostle says, by the Holy Ghost, to rule the Church of God; that they are superior to priests; administer the sacrament of Confirmation; ordain the ministers of the Church; and that they can perform very many other things; over which functions others of an inferior order have no power. Furthermore, the sacred and holy Synod teaches, that, in the ordination of bishops, priests, and of the other orders, neither the consent, nor vocation, nor authority, whether of the people, or of any civil power or magistrate whatsoever, is required in such wise as that, without this, the ordination is invalid: yea rather doth It decree, that all those who, being only called and instituted by the people, or by the civil power and magistrate, ascend to the exercise of these ministrations, and those who of their own rashness assume them to themselves, are not ministers of the church, but are to be looked upon as thieves and robbers, who have not entered by the door. These are the things which it hath seemed good to the sacred Synod to teach the faithful in Christ, in general terms, touching the sacrament of Order. But It hath resolved to condemn whatsoever things are contrary thereunto, in express and specific canons, in the manner following; in order that all men, with the help of Christ, using the rule of faith, may, in the midst of the darkness of so many errors, more easily be able to recognise and to hold Catholic truth.
