The adversaries understand priesthood not of the ministry of the Word, and administering the Sacraments to others, but they understand it as referring to sacrifice, as though in the New Testament there ought to be a priesthood like the Levitical, to sacrifice for the people, and merit the remission of sins for others. We teach that the sacrifice of Christ dying on the cross has been sufficient for the sins of the whole world, and that there is no need, besides, of other sacrifices, as though this were not sufficient for our sins. Men, accordingly, are justified not because of any other sacrifices, but because of this one sacrifice of Christ, if they believe that they have been redeemed by this sacrifice. They are accordingly called priests, not in order to make any sacrifices for the people as in the Law so that by these they may merit remission of sins for the people; but they are called to teach the Gospel and administer the Sacraments to the people. Nor do we have another priesthood like the Levitical, as the Epistle to the Hebrews sufficiently teaches. But if ordination be understood as applying to the ministry of the Word, we are not unwilling to call ordination a sacrament. For the ministry of the Word has God's command and glorious promises, Rom. 1, 16: The Gospel is the power of God unto salvation to every one that believeth. Likewise, Is. 55, 11: So shall My Word be that goeth forth out of My mouth; it shall not return unto Me void, but it shall accomplish that which I please. If ordination be understood in this way, neither will we refuse to call the imposition of hands a sacrament. For the Church has the command to appoint ministers, which should be most pleasing to us, because we know that God approves this ministry and is present in the ministry [that God will preach and work through men and those who have been chosen by men]. And it is of advantage, so far as can be done, to adorn the ministry of the Word with every kind of praise against fanatical men, who dream that the Holy Ghost is given not through the Word, but because of certain preparations of their own, if they sit unoccupied and silent in obscure places, waiting for illumination, as the Enthusiasts formerly taught, and the Anabaptists now teach. Matrimony was not first instituted in the New Testament, but in the beginning, immediately on the creation of the human race. It has, moreover, God's command; it has also promises, not indeed properly pertaining to the New Testament, but pertaining rather to the bodily life. Wherefore, if any one should wish to call it a sacrament, he ought still to distinguish it from those preceding ones [the two former ones], which are properly signs of the New Testament, and testimonies of grace and the remission of sins. But if marriage will have the name of sacrament for the reason that it has God's command other states or offices also, which have God's command, may be called sacraments, as, for example, the magistracy.
