And that it was Peter's wont to speak in a shallow manner is proved by his hasty and thoughtless forwardness, to which he was led not only by the sincerity of his faith, but also, I believe, by the natural purity and simplicity of his character. All the Evangelists bear testimony to this forwardness.
Matthew writes that when Jesus had asked His disciples: "Whom say ye that I am?" Peter answered before them all and said: "Thou art Christ, the Son of the living God." He writes also that when Christ was saying to His disciples that he must go up to Jerusalem and suffer many things, Peter took Him and began to rebuke Him, saying: "Be it far from Thee, Lord; this shall not be unto Thee." But Christ turned and rebuked him, and said: "Get thee behind me, Satan." Matthew also writes that in the Mount of Transfiguration, on the sight of Christ, and of Moses and Elias, and of the two sons of Zebedee, Peter said: "Lord, it is good for us to be here; if Thou wilt, let us make here three tabernacles, one for Thee, one for Moses, and one for Elias." He also writes that when the disciples were in a ship, in the night, and Christ went unto them walking on the sea, then Peter said unto Him: "Lord, if it be Thou, bid me come unto Thee on the water." And when Christ foretold that all His disciples should be offended because of Him, Peter answered and said: "Though all men shall be offended because of Thee, yet will I never be offended;" and then: "Though I should die with Thee, yet will I not deny Thee." And to this saying Mark bears witness also. And Luke writes that Peter had said to Christ, a little before the words touching the swords which we have quoted: "Lord, I am ready to go with Thee, both into prison and to death." And John says of him, that, when Christ wished to wash his feet, Peter answered and said: "Lord, dost Thou wash my feet?" and then: "Thou shalt never wash my feet." The same Evangelist tells us that it was Peter who smote the High Priest's servant with a sword, and the other Evangelists also bear witness to this thing. He tells us also how Peter entered the sepulchre at once, when he saw the other disciple waiting outside, and how, when Christ was on the shore after the resurrection, when Peter had heard that it was the Lord, he girt his fisher's coat unto him (for he was naked) and did cast himself into the sea. Lastly, John tells that when Peter saw John, he said unto Jesus: "Lord, and what shall this man do?"
It is a pleasure to have pursued this point about our Chief Shepherd,[293] in praise of his purity of spirit; but from what I have said it is plain that when he spake of the two swords, he answered the words of Christ with no second meaning.
But if we are to receive these words of Christ and of Peter typically, they must not be explained as our adversaries explain them; but they must be referred to that sword of which Matthew writes: "Think not that I am come to send peace on the earth; I come not to send peace, but a sword. For I am come to set a man at variance against his father," &c. And this comes to pass not only in words, but also in fact. And therefore Luke speaks to Theophilus of all "that Jesus began both to do and to teach." It was a sword of that kind that Christ commanded them to buy; and Peter said that it was already doubly there. For they were ready both for words and for deeds, by which they should accomplish what Christ said that He had come to do by the sword.
X.—Certain persons say further that the Emperor Constantine, having been cleansed from leprosy by the intercession of Sylvester, then the Supreme Pontiff, gave unto the Church the seat of Empire which was Rome, together with many other dignities belonging to the Empire.[294] Hence they argue that no man can take unto himself these dignities unless he receive them from the Church, whose they are said to be. From this it would rightly follow, that one authority depends on the other, as they maintain.
The arguments which seemed to have their roots in the Divine words, have been stated and disproved. It remains to state and disprove those which are grounded on Roman history and in the reason of mankind. The first of these is the one which we have mentioned, in which the syllogism runs as follows: No one has a right to those things which belong to the Church, unless he has them from the Church; and this we grant. The government of Rome belongs to the Church; therefore no one has a right to it unless it be given him by the Church. The minor premiss is proved by the facts concerning Constantine, which we have touched on.
This minor premiss then will I destroy; and as for their proof, I say that it proves nothing. For the dignity of the Empire was what Constantine could not alienate, nor the Church receive. And when they insist, I prove my words as follows: No man on the strength of the office which is committed to him, may do aught that is contrary to that office; for so one and the same man, viewed as one man, would be contrary to himself, which is impossible. But to divide the Empire is contrary to the office committed to the Emperor; for his office is to hold mankind in all things subject to one will: as may be easily seen from the first book of this treatise. Therefore it is not permitted to the Emperor to divide the Empire. If, therefore, as they say, any dignities had been alienated by Constantine, and had passed to the Church, the "coat without seam"—which even they, who pierced Christ, the true God, with a spear, dared not rend—would have been rent.[295]
Further, just as the Church has its foundation, so has the Empire its foundation. The foundation of the Church is Christ, as Paul says in his first Epistle to the Corinthians: "For other foundation can no man lay than that which is laid, which is Jesus Christ."[296] He is the rock on which the Church is built; but the foundation of the Empire is human right. Now I say that, as the Church may not go contrary to its foundation—but must always rest on its foundation, as the words of the Canticles say: "Who is she that cometh up from the desert, abounding in delights, leaning on her beloved?"[297]—in the same way I say that the Empire may not do aught that transgresses human right. But were the Empire to destroy itself, it would so transgress human right. Therefore the Empire may not destroy itself. Since then to divide the Empire would be to destroy it, because the Empire consists in one single universal Monarchy, it is manifest that he who exercises the authority of the Empire may not destroy it, and from what we have said before, it is manifest that to destroy the Empire is contrary to human right.
Moreover, all jurisdiction is prior in time to the judge who has it; for it is the judge who is ordained for the jurisdiction, not the jurisdiction for the judge. But the Empire is a jurisdiction, comprehending within itself all temporal jurisdiction: therefore it is prior to the judge who has it, who is the Emperor. For it is the Emperor who is ordained for the Empire, and not contrariwise. Therefore it is clear that the Emperor, in so far as he is Emperor, cannot alter the Empire; for it is to the Empire that he owes his being. I say then that he who is said to have conferred on the Church the authority in question either was Emperor, or he was not. If he was not, it is plain that he had no power to give away any part of the Empire. Nor could he, if he was Emperor, in so far as he was Emperor, for such a gift would be a diminishing of his jurisdiction.
Further, if one Emperor were able to cut off a certain portion of the jurisdiction of the Empire, so could another; and since temporal jurisdiction is finite, and since all that is finite is taken away by finite diminutions, it would follow that it is possible for the first of all jurisdictions to be annihilated, which is absurd.
