Chap. 60.-135. Petilianus said: "Under what law, then, do you make out that you are Christians, seeing that you do what is contrary to the law?"
136. Augustin answered: You are anxious for strife, and not for argument.
Chap. 61.-137. Petilianus said: "But the Lord Christ says, 'Whosoever shall do and teach them, the same shall be called the greatest in the kingdom of heaven.' But He condemns you wretched men as follows: 'Whosoever shall break one of these commandments, he shalt be called the least in the kingdom of heaven.'"
138. Augustin answered: When you happen to quote the testimony of Scripture as other than it really is, and it does not bear on the question which is at issue between us, I am not greatly concerned; but when it interferes with the matter on hand, unless it is quoted truly, then I think that you have no right to find fault if I remind you how the passage really stands. For you must be aware that the verse which you quoted is not as you quoted it, but rather thus: "Whosoever shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven; but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven." And immediately He continues, "For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven." For elsewhere He shows and proves of the Pharisees that they say and do not. It is these, therefore, to whom He is referring also here, when He said, "Whosoever shall break one of these commandments, and shall teach men so,"-that is, shall teach in words what he has violated in deeds; whose righteousness He says that our righteousness must excel, in that we must both keep the commandments and teach men so. And yet not even on account of those Pharisees, with whom you compare us,-not from any motives of prudence, but from malice,-did our Lord enjoin that the seat of Moses should be deserted, which seat He doubtless meant to be a figure of His own; for He said indeed that they who sat in Moses' seat were ever saying and not doing, but warns the people to do what they say, and not to do what they do, lest the chair, with all its holiness, should be deserted, and the unity of the flock divided through the faithlessness of the shepherds.
Chap. 62.-139. Petilianus said: "And again it is written, 'Every sin which a man shall sin is without the body; but he that sinneth in the Holy Spirit, it shall not be forgiven him, neither in this world, neither in the world to come.'"
140. Augustin answered: This too is not written as you have quoted it, and see how far it has led you astray. The apostle, writing to the Corinthians, says, "Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body." But this is one thing, and that is another which the Lord said in the gospel: "All manner of sin and blasphemy shall be forgiven unto men: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come." But you have begun a sentence from the writing of the apostle, and ended it as though it were one from the gospel, which I fancy you have done not with any intention to deceive, but through mistake; for neither passage has any bearing on the matter in hand. And why you have said this, and in what sense you have said it, I am wholly unable to perceive, unless it be that, whereas you had said above that all were condemned by the Lord who had broken any one of His commandments, you have considered since how many there are in your party who break not one but many of them; and lest an objection should be brought against you on that score, you have sought, by way of surpassing the difficulty, to bring in a distinction of sins, whereby it might be seen that it is one thing to break a commandment in respect of which pardon may easily be obtained, another thing to sin against the Holy Ghost, which shall receive no forgiveness, either in this world or in the world to come. In your dread, therefore, of infection from sin, you were unwilling to pass this over in silence; and again, in your dread of a question too deep for your powers, you wish to touch cursorily on it in passing, in such a state of agitation, that, just as men who are setting about a task in haste, and consequent confusion, are wont to fasten their dress or shoes awry, so you have not thought fit either to see what belongs to what, or in what context or what sense the passage which you quote occurs. But what is the nature of that sin which shall not be forgiven, either in this world or in the world to come, you are so far from knowing, that, though you believe that we are actually living in it, you yet promise us forgiveness of it through your baptism. And yet how could this be possible, if the sin be of such a nature that it cannot be forgiven, either in this world or in the world to come?
