Chapter XII.
In the next place, since he reproaches us with the existence of heresies in Christianity as being a ground of accusation against it, saying that "when Christians had greatly increased in numbers, they were divided and split up into factions, each individual desiring to have his own party;" and further, that "being thus separated through their numbers, they confute one another, still having, so to speak, one name in common, if indeed they still retain it. And this is the only thing which they are yet ashamed to abandon, while other matters are determined in different ways by the various sects." In reply to which, we say that heresies of different kinds have never originated from any matter in which the principle involved was not important and beneficial to human life. For since the science of medicine is useful and necessary to the human race, and many are the points of dispute in it respecting the manner of curing bodies, there are found, for this reason, numerous heresies confessedly prevailing in the science of medicine among the Greeks, and also, I suppose, among those barbarous nations who profess to employ medicine. And, again, since philosophy makes a profession of the truth, and promises a knowledge of existing things with a view to the regulation of life, and endeavours to teach what is advantageous to our race, and since the investigation of these matters is attended with great differences of opinion, [3472] innumerable heresies have consequently sprung up in philosophy, some of which are more celebrated than others. Even Judaism itself afforded a pretext for the origination of heresies, in the different acceptation accorded to the writings of Moses and those of the prophets. So, then, seeing Christianity appeared an object of veneration to men, not to the more servile class alone, as Celsus supposes, but to many among the Greeks who were devoted to literary pursuits, [3473] there necessarily originated heresies,--not at all, however, as the result of faction and strife, but through the earnest desire of many literary men to become acquainted with the doctrines of Christianity. The consequence of which was, that, taking in different acceptations those discourses which were believed by all to be divine, there arose heresies, which received their names from those individuals who admired, indeed, the origin of Christianity, but who were led, in some way or other, by certain plausible reasons, to discordant views. And yet no one would act rationally in avoiding medicine because of its heresies; nor would he who aimed at that which is seemly [3474] entertain a hatred of philosophy, and adduce its many heresies as a pretext for his antipathy. And so neither are the sacred books of Moses and the prophets to be condemned on account of the heresies in Judaism.

Now, if these arguments hold good, why should we not defend, in the same way, the existence of heresies in Christianity? And respecting these, Paul appears to me to speak in a very striking manner when he says, "For there must be heresies among you, that they who are approved may be made manifest among you." [3475] For as that man is "approved" in medicine who, on account of his experience in various (medical) heresies, and his honest examination of the majority of them, has selected the preferable system,--and as the great proficient in philosophy is he who, after acquainting himself experimentally with the various views, has given in his adhesion to the best,--so I would say that the wisest Christian was he who had carefully studied the heresies both of Judaism and Christianity. Whereas he who finds fault with Christianity because of its heresies would find fault also with the teaching of Socrates, from whose school have issued many others of discordant views. Nay, the opinions of Plato might be chargeable with error, on account of Aristotle's having separated from his school, and founded a new one,--on which subject we have remarked in the preceding book. But it appears to me that Celsus has become acquainted with certain heresies which do not possess even the name of Jesus in common with us. Perhaps he had heard of the sects called Ophites and Cainites, or some others of a similar nature, which had departed in all points from the teaching of Jesus. And yet surely this furnishes no ground for a charge against the Christian doctrine.
