And in answer to the Greeks we shall quote the following oracular response to Laius, as recorded by the tragic poet, either in the exact words of the oracle or in equivalent terms. Future events are thus made known to him by the oracle: “Do not try to beget children against the will of the gods. For if you beget a son, your son shall murder you; and all your household shall wade in blood.” Now from this it is clear that it was within the power of Laius not to try to beget children, for the oracle would not have commanded an impossibility; and it was also in his power to do the opposite, so that neither of these courses was compulsory. And the consequence of his not guarding against the begetting of children was, that he suffered from so doing the calamities described in the tragedies relating to Œdipus and Jocasta and their sons. Now that which is called the “idle argument,” being a quibble, is such as might be applied, say in the case of a sick man, with the view of sophistically preventing him from employing a physician to promote his recovery; and it is something like this: “If it is decreed that you should recover from your disease, you will recover whether you call in a physician or not; but if it is decreed that you should not recover, you will not recover whether you call in a physician or no. But it is certainly decreed either that you should recover, or that you should not recover; and therefore it is in vain that you call in a physician.” Now with this argument the following may be wittily compared: “If it is decreed that you should beget children, you will beget them, whether you have intercourse with a woman or not. But if it is decreed that you should not beget children, you will not do so, whether you have intercourse with a woman or no. Now, certainly, it is decreed either that you should beget children or not; therefore it is in vain that you have intercourse with a woman.” For, as in the latter instance, intercourse with a woman is not employed in vain, seeing it is an utter impossibility for him who does not use it to beget children; so, in the former, if recovery from disease is to be accomplished by means of the healing art, of necessity the physician is summoned, and it is therefore false to say that “in vain do you call in a physician.” We have brought forward all these illustrations on account of the assertion of this learned Celsus, that “being a God He predicted these things, and the predictions must by all means come to pass.” Now, if by “by all means” he means “necessarily,” we cannot admit this. For it was quite possible, also, that they might not come to pass. But if he uses “by all means” in the sense of “simple futurity,” which nothing hinders from being true (although it was possible that they might not happen), he does not at all touch my argument; nor did it follow, from Jesus having predicted the acts of the traitor or the perjurer, that it was the same thing with His being the cause of such impious and unholy proceedings. For He who was amongst us, and knew what was in man, seeing his evil disposition, and foreseeing what he would attempt from his spirit of covetousness, and from his want of stable ideas of duty towards his Master, along with many other declarations, gave utterance to this also: “He that dippeth his hand with Me in the dish, the same shall betray Me.”
