Chap. xlix.—113. Petilianus said: "For, granting that you faithless ones are acquainted with the law, without any prejudice to the law itself, I may say so much as this, the devil knows it too. For in the case of righteous Job he answered the Lord God concerning the law as though he were himself righteous, as it is written, 'And the Lord said unto Satan, Hast thou considered my servant Job, that there is none like him in the earth, a perfect and an upright man, one that feareth God and escheweth evil? and still he holdeth fast his integrity, although thou movedst me against him, to destroy him without cause. And Satan answered the Lord, Skin for skin, yea, all that a man hath will he give for his life.'[844] Behold he speaks in legal phrase, even when he is striving against the law. And a second time he endeavoured thus to tempt the Lord Christ with his discourse, as it is written, 'The devil taketh Jesus into the holy city, and setteth Him on a pinnacle of the temple, and saith unto Him, If thou be the Son of God, cast thyself down: for it is written, He shall give His angels charge over thee; and in their hands they shall bear thee up, lest at any time thou dash thy foot against a stone. Jesus said unto him, It is written again, Thou shalt not tempt the Lord thy God.'[845] You know the law, I say, as did the devil, who is conquered in his endeavours, and blushes in his deeds."
114. Augustine answered: I might indeed ask of you in what law the words are written which the devil used when he was uttering calumnies against the holy man Job, if the position which I am set to prove were this, that you yourself are unacquainted with the law which you assert the devil to have known; but as this is not the question at issue between us, I pass it by. But you have endeavoured in such sort to prove that the devil is skilled in the law, as though we maintained that all who know the law are just. Accordingly, I do not see in what manner you are assisted by what you have chosen to quote concerning the devil,—unless, indeed, it may be that we should be thereby reminded how you imitate the devil himself. For as he brought forward the words of the law against the Author of the law, so you also out of the words of the law bring accusation against men whom you do not know, that you may resist the promises of God which are made in that very self-same law. Then I should be glad if you would tell me in whose honour do those confessors of yours achieve their martyrdom, when they throw themselves over precipices,—in honour of Christ, who thrust the devil from Him when he made a like suggestion, or rather in honour of the devil himself, who suggested such a deed to Christ? There are two especially vile and customary deaths resorted to by those who kill themselves,—hanging and the precipice. You assuredly said in the earlier part of this epistle, "The traitor hung himself: he left this death to all who are like him." This has no application whatever to us; for we refuse to reverence with the name of martyr any who have strangled themselves. With how much greater show of reason might we say against you, That master of all traitors, the devil, wished to persuade Christ to throw Himself headlong down, and was repulsed! What, therefore, must we say of those whom he persuaded with success? What, indeed, except that they are the enemies of Christ, the friends of the devil, the disciples of the seducer, the fellow-disciples of the traitor? For both have learned to kill themselves from the same master,—Judas by hanging himself, the others by throwing themselves over precipices.
Chap. l.—115. Petilianus said: "But that we may destroy your arguments one by one, if you call yourselves by the name of priests, it was said by the Lord God, through the mouth of His prophet, 'The vengeance of the Lord is upon the false priests.'"
116. Augustine answered: Seek rather what you may say with truth, not whence you may derive abusive words; and what you may teach, not what reproaches you may cast in our teeth.
Chap. li.—117. Petilianus said: "If you wretched men claim for yourselves a seat, as we said before, you assuredly have that one of which the prophet and psalmist David speaks as being the seat of the scornful.[846] For to you it is rightly left, seeing that the holy cannot sit therein."
118. Augustine answered: Here again you do not see that this is no kind of argument, but empty abuse. For this is what I said a little while ago, You utter the words of the law, but take no heed against whom you utter them; just as the devil uttered the words of the law, but failed to perceive to whom he uttered them. He wished to thrust down our Head, who was presently to ascend on high; but you wish to reduce to a small fraction the body of that same Head which is dispersed throughout the entire world. Certainly you yourself said a little time before that we know the law, and speak in legal terms, but blush in our deeds. Thus much indeed you say without a proof of anything; but even though you were to prove it of some men, you would not be entitled to assert it of these others. However, if all men throughout all the world were of the character which you most vainly charge them with, what has the chair done to you of the Roman Church, in which Peter sat, and which Anastasius fills to-day; or the chair of the Church of Jerusalem, in which James once sat, and in which John sits to-day, with which we are united in catholic unity, and from which you have severed yourselves by your mad fury? Why do you call the apostolic chair a seat of the scornful? If it is on account of the men whom you believe to use the words of the law without performing it, do you find that our Lord Jesus Christ was moved by the Pharisees, of whom He says, "They say, and do not," to do any despite to the seat in which they sat? Did He not commend the seat of Moses, and maintain the honour of the seat, while He convicted those that sat in it? For He says, "They sit in Moses' seat: all therefore whatsoever they bid you observe, that observe and do; but do ye not after their works: for they say, and do not."[847] If you were to think of these things, you would not, on account of men whom you calumniate, do despite to the apostolic seat, in which you have no share. But what else is conduct like yours but ignorance of what to say, combined with want of power to abstain from evil-speaking?
