23 You call upon me to bring forward the name of even one whose opinion I have followed in this matter, and at the same time you have quoted the names of many who have held before you the opinion which you defend. You also say that if I censure you for an error in this, you beg to be allowed to remain in error in company with such great men. I have not read their writings; but although they are only six or seven in all, you have yourself impugned the authority of four of them. For as to the Laodicean author, whose name you do not give, you say that he has lately forsaken the Church; Alexander you describe as a heretic of old standing; and as to Origen and Didymus, I read in some of your more recent works, censure passed on their opinions, and that in no measured terms, nor in regard to insignificant questions, although formerly you gave Origen marvellous praise. I suppose, therefore, that you would not even yourself be contented to be in error with these men; although the language which I refer to is equivalent to an assertion that in this matter they have not erred. For who is there that would consent to be knowingly mistaken, with whatever company he might share his errors? Three of the seven therefore alone remain, Eusebius of Emesa, Theodorus of Heraclea, and John, whom you afterwards mention, who formerly presided as pontiff over the Church of Constantinople.
24. However, if you inquire or recall to memory the opinion of our Ambrose, and also of our Cyprian, on the point in question, you will perhaps find that I also have not been without some whose footsteps I follow in that which I have maintained. At the same time, as I have said already, it is to the canonical Scriptures alone that I am bound to yield such implicit subjection as to follow their teaching, without admitting the slightest suspicion that in them any mistake or any statement intended to mislead could find a place. Wherefore, when I look round for a third name that I may oppose three on my side to your three, I might indeed easily find one, I believe, if my reading had been extensive; but one occurs to me whose name is as good as all these others, nay, of greater authority— I mean the Apostle Paul himself. To him I betake myself; to himself I appeal from the verdict of all those commentators on his writings who advance an opinion different from mine. I interrogate him, and demand from himself to know whether he wrote what was true, or under some plea of expediency wrote what he knew to be false, when he wrote that he saw Peter not walking uprightly, according to the truth of the gospel, and withstood him to his face because by that dissimulation he was compelling the Gentiles to live after the manner of the Jews. And I hear him in reply proclaiming with a solemn oath in an earlier part of the epistle, where he began this narration, “The things that I write unto you, behold, before God, I lie not.”
25. Let those who think otherwise, however great their names, excuse my differing from them. The testimony of so great an apostle using, in his own writings, an oath as a confirmation of their truth, is of more weight with me than the opinion of any man, however learned, who is discussing the writings of another. Nor am I afraid lest men should say that, in vindicating Paul from the charge of pretending to conform to the errors of Jewish prejudice, I affirm him to have actually so conformed. For as, on the one hand, he was not guilty of pretending conformity to error when, with the liberty of an apostle, such as was suitable to that period of transition, he did, by practising those ancient holy ordinances, when it was necessary to declare their original excellence as appointed not by the wiles of Satan to deceive men, but by the wisdom of God for the purpose of typically foretelling things to come; so, on the other hand, he was not guilty of real conformity to the errors of Judaism, seeing that he not only knew, but also preached constantly and vehemently, that those were in error who thought that these ceremonies were to be imposed upon the Gentile converts, or were necessary to the justification of any who believed.
26. Moreover, as to my saying that to the Jews he became as a Jew, and to the Gentiles as a Gentile, not with the subtlety of intentional deceit, but with the compassion of pitying love, it seems to me that you have not sufficiently considered my meaning in the words; or rather, perhaps, I have not succeeded in making it plain. For I did not mean by this that I supposed him to have practised in either case a feigned conformity; but I said it because his conformity was sincere, not less in the things in which he became to the Jews as a Jew, than in those in which he became to the Gentiles as a Gentile,— a parallel which you yourself suggested, and by which I thankfully acknowledge that you have materially assisted my argument. For when I had in my letter asked you to explain how it could be supposed that Paul's becoming to the Jews as a Jew involved the supposition that he must have acted deceitfully in conforming to the Jewish observances, seeing that no such deceptive conformity to heathen customs was involved in his becoming as a Gentile to the Gentiles; your answer was, that his becoming to the Gentiles as a Gentile meant no more than his receiving the uncircumcised, and permitting the free use of those meats which were pronounced unclean by Jewish law. If, then, when I ask whether in this also he practised dissimulation, such an idea is repudiated as palpably most absurd and false: it is an obvious inference, that in his performing those things in which he became as a Jew to the Jews, he was using a wise liberty, not yielding to a degrading compulsion, nor doing what would be still more unworthy of him, viz. stooping from integrity to fraud out of a regard to expediency.
27. For to believers, and to those who know the truth, as the apostle testifies (unless here too, perhaps, he is deceiving his readers), “every creature of God is good, and nothing to be refused, if it be received with thanksgiving.” Therefore to Paul himself, not only as a man, but as a steward eminently faithful, not only as knowing, but also as a teacher of the truth, every creature of God which is used for food was not feignedly but truly good. If, then, to the Gentiles he became as a Gentile, by holding and teaching the truth concerning meats and circumcision although he feigned no conformity to the rites and ceremonies of the Gentiles, why say that it was impossible for him to become as a Jew to the Jews, unless he practised dissimulation in performing the rites of their religion? Why did he maintain the true faithfulness of a steward towards the wild olive branch that was engrafted, and yet hold up a strange veil of dissimulation, on the plea of expediency, before those who were the natural and original branches of the olive tree? Why was it that, in becoming as a Gentile to the Gentiles, his teaching and his conduct are in harmony with his real sentiments; but that, in becoming as a Jew to the Jews, he shuts up one thing in his heart, and declares something wholly different in his words, deeds, and writings? But far be it from us to entertain such thoughts of him. To both Jews and Gentiles he owed “charity out of a pure heart, and of a good conscience, and of faith unfeigned;” and therefore he became all things to all men, that he might gain all, not with the subtlety of a deceiver, but with the love of one filled with compassion; that is to say, not by pretending himself to do all the evil things which other men did, but by using the utmost pains to minister with all compassion the remedies required by the evils under which other men laboured, as if their case had been his own.
