63. Augustine replied: These words of yours are arguments against yourselves; but in your madness you are not aware of it. For the men who say there are two baptisms are those who declare their opinion that the just and the unjust have different baptisms; whereas it belongs neither to one party nor the other, but in both of them is one, being Christ's, although they themselves are not one: and yet the baptism, which is one, the just have to salvation, the unjust to their destruction.
Chap. xxviii.—64. Petilianus said: "But yet, if I may be allowed the comparison, it is certain that the sun appears double to the insane, although it only be that a dark blue cloud often meets it, and its discoloured surface, being struck by the brightness, while the rays of the sun are reflected from it, seems to send forth as it were rays of its own. So in the same way in the faith of baptism, it is one thing to seek for reflections, another to recognise the truth."
65. Augustine answered: What are you saying, if I may ask? When a dark blue cloud reflects the rays of the sun with which it is struck, is it only to the insane, and not to all who look on it, that there appear to be two suns? But when it appears so to the insane as such, it appears to them alone. But if I may say so without being troublesome, I would have you take care lest saying such things and talking in such a way should be itself a sign of madness. I suppose, however, that what you meant to say was this,—that the just had the truth of baptism, the unjust only its reflection. And if this be so, I venture to say that the reflection was found in that man of your party,[775] to whom not God, but a certain Count,[776] was God; but that the truth was either in you or in him who uttered the witty saying against Optatus, when he said that "in the Count he had a god for his companion."[777] And distinguish between those who were baptized by either of these, and in the one party approve the true baptism, in the others exclude the reflection, and introduce the truth.
Chap. xxix.—66. Petilianus said: "But to pass rapidly through these minor points: can he be said to lay down the law who is not a magistrate of the court? or is what he lays down to be considered law, when in the character of a private person he disturbs public rights? Is it not rather the case that he not only involves himself in guilt, but is held to be a forger, and that which he composes a forgery?"
67. Augustine answered: What if your private person, whom you deem a forger, were to set forth to any one the law of the emperor? Would not the man, when he had compared it with the law of those who have the genuine law, and found it to be identically the same, lay aside all care about the source from which he had obtained it, and consider only what he had obtained? For what the forger gives is false when he gives it of his own falseness; but when something true is given by any person, even though he be a forger, yet, although the giver be not truthful, the gift is notwithstanding true.
Chap. xxx.—68. Petilianus said: "Or if any one chance to recollect the chants of a priest, is he therefore to be deemed a priest, because with sacrilegious mouth he publishes the strain of a priest?"
69. Augustine answered: In this question you are speaking just as though we were at present inquiring what constituted a true priest, not what constituted true baptism. For that a man should be a true priest, it is requisite that he should be clothed not with the sacrament alone, but with righteousness, as it is written, "Let thy priests be clothed with righteousness."[778] But if a man be a priest in virtue of the sacrament alone, as was the high priest Caiaphas, the persecutor of the one most true Priest, then even though he himself be not truthful, yet what he gives is true, if he gives not what is his own but what is God's; as it is said of Caiaphas himself, "This spake he not of himself: but being high priest that year, he prophesied."[779] And yet, to use the same simile which you employed yourself: if you were to hear even from any one that was profane the prayer of the priest couched in the words suitable to the mysteries of the gospel, can you possibly say to him, Your prayer is not true, though he himself may be not only no true priest, but not a priest at all? seeing that the Apostle Paul said that certain testimony of I know not what Cretan prophet was true, though he was not reckoned among the prophets of God; for he says, "One of themselves, even a prophet of their own, said the Cretians are always liars, evil beasts, slow bellies: this witness is true."[780] If, therefore, the apostle even himself bore witness to the testimony of some obscure prophet of a foreign race, because he found it to be true, why do not we, when we find in any one what belongs to Christ, and is true even though the man with whom it may be found be deceitful and perverse, why do not we in such a case make a distinction between the fault which is found in the man, and the truth which he has not of his own but of God's? and why do we not say, This sacrament is true, as Paul said, "This witness is true?" Does it at all follow that we say, The man himself also is truthful, because we say, This sacrament is true? Just as I would ask whether the apostle counted that prophet among the prophets of the Lord, because he confirmed the truth of what he found to be true in him. Likewise the same apostle, when he was at Athens, perceived a certain altar among the altars of the false gods, on which was the inscription, "To the unknown God." And this testimony he made use of to build them up in Christ, to the extent of quoting the inscription in his sermon, and adding, "Whom, therefore, ye ignorantly worship, Him declare I unto you." Did he, because he found that altar either among the altars of idols, or set up by sacrilegious hands, therefore condemn or reject what he found in it that was true? or did he, because of the truth which he found upon it, therefore persuade them that they ought also to follow the sacrilegious practices of the pagans? Surely he did neither of the two; but presently, when, as he judged fitting, he wished to introduce to their knowledge the Lord Himself, unknown to them, but known to him, he says among other things, that "He is not far from every one of us: for in Him we live, and move, and have our being; as certain also of your own poets have said."[781] Can it be said that here also, because he found among the sacrilegious the evidence of truth, he either approved their wickedness because of the evidence, or condemned the evidence because of their wickedness? But it is unavoidable that you should be always in the wrong, so long as you do despite to the sacraments of God because of the faults of men, or think that we take upon ourselves the sacrilege even of your schism, for the sake of the sacraments of God, to which we are unwilling to do despite in you.
