It remains to consider the third, and, indeed, when matters are well arranged, the principal part of ecclesiastical power, which, as we have said, consists in jurisdiction. Now, the whole jurisdiction of the Church relates to discipline, of which we are shortly to treat. For as no city or village can exist without a magistrate and government, so the Church of God, as I have already taught, but am again obliged to repeat, needs a kind of spiritual government. This is altogether distinct from civil government, and is so far from impeding or impairing it, that it rather does much to aid and promote it. Therefore, this power of jurisdiction is, in one word, nothing but the order provided for the preservation of spiritual polity. To this end, there were established in the Church from the first, tribunals which might take cognisance of morals, animadvert on vices, and exercise the office of the keys. This order is mentioned by Paul in the First Epistle to the Corinthians under the name of governments (1 Cor. 12:28): in like manner, in the Epistle to the Romans, when he says, "He that ruleth with diligence" (Rom. 12:8). For he is not addressing magistrates, none of whom were then Christians, but those who were joined with pastors in the spiritual government of the Church. In the Epistle to Timothy, also, he mentions two kinds of presbyters, some who labour in the word, and others who do not perform the office of preaching, but rule well (1 Tim. 5:17). By this latter class there is no doubt he means those who were appointed to the inspection of manners, and the whole use of the keys. For the power of which we speak wholly depends on the keys which Christ bestowed on the Church in the eighteenth chapter of Matthew, where he orders, that those who despise private admonition should be sharply rebuked in public, and if they persist in their contumacy, be expelled from the society of believers. Moreover, those admonitions and corrections cannot be made without investigation, and hence the necessity of some judicial procedure and order. Wherefore, if we would not make void the promise of the keys, and abolish altogether excommunication, solemn admonitions, and everything of that description, we must, of necessity, give some jurisdiction to the Church. Let the reader observe that we are not here treating of the general authority of doctrine, as in Mt. 21 and John 20, but maintaining that the right of the Sanhedrim is transferred to the fold of Christ. Till that time, the power of government had belonged to the Jews. This Christ establishes in his Church, in as far as it was a pure institution, and with a heavy sanction. Thus it behoved to be, since the judgment of a poor and despised Church might otherwise be spurned by rash and haughty men. And lest it occasion any difficulty to the reader, that Christ in the same words makes a considerable difference between the two things, it will here be proper to explain. There are two passages which speak of binding and loosing. The one is Mt. 16, where Christ, after promising that he will give the keys of the kingdom of heaven to Peter, immediately adds, "Whatsoever thou shalt bind on earth shall be bound in heaven; and whatsoever thou shalt loose on earth shall be loosed in heaven" (Mt. 16:19). These words have the very same meaning as those in the Gospel of John, where, being about to send forth the disciples to preach, after breathing on them, he says, "Whose soever sins ye remit, they are remitted unto them; and whose soever sins ye retain, they are retained" (John 20:23). I will give an interpretation, not subtle, not forced, not wrested, but genuine, natural, and obvious. This command concerning remitting and retaining sins, and that promise made to Peter concerning binding and loosing, ought to be referred to nothing but the ministry of the word. When the Lord committed it to the apostles, he, at the same time, provided them with this power of binding and loosing. For what is the sum of the gospel, but just that all being the slaves of sin and death, are loosed and set free by the redemption which is in Christ Jesus, while those who do not receive and acknowledge Christ as a deliverer and redeemer are condemned and doomed to eternal chains? When the Lord delivered this message to his apostles, to be carried by them into all nations, in order to prove that it was his own message, and proceeded from him, he honoured it with this distinguished testimony, and that as an admirable confirmation both to the apostles themselves, and to all those to whom it was to come. It was of importance that the apostles should have a constant and complete assurance of their preaching, which they were not only to exercise with infinite labour, anxiety, molestation, and peril, but ultimately to seal with their blood. That they might know that it was not vain or void, but full of power and efficacy, it was of importance, I say, that amidst all their anxieties, dangers, and difficulties, they might feel persuaded that they were doing the work of God; that though the whole world withstood and opposed them, they might know that God was for them; that not having Christ the author of their doctrine bodily present on the earth, they might understand that he was in heaven to confirm the truth of the doctrine which he had delivered to them. On the other hand, it was necessary that their hearers should be most certainly assured that the doctrine of the gospel was not the word of the apostles, but of God himself; not a voice rising from the earth, but descending from heaven. For such things as the forgiveness of sins, the promise of eternal life, and message of salvation, cannot be in the power of man. Christ therefore testified, that in the preaching of the gospel the apostles only acted ministerially; that it was he who, by their mouths as organs, spoke and promised all; that, therefore, the forgiveness of sins which they announced was the true promise of' God; the condemnation which they pronounced, the certain judgment of God. This attestation was given to all ages, and remains firm, rendering all certain and secure, that the word of the gospel, by whomsoever it may be preached, is the very word of God, promulgated at the supreme tribunal, written in the book of life, ratified firm and fixed in heaven. We now understand that the power of the keys is simply the preaching of the gospel in those places, and in so far as men are concerned, it is not so much power as ministry. Properly speaking, Christ did not give this power to men but to his word, of which he made men the ministers.
