Chapter XIV.
In the next place, wishing to shake the faith of those who believe in Jesus on the ground of the prophecies which were delivered in regard to Him, Celsus says: "But pray, if the prophets foretold that the great God--not to put it more harshly--would become a slave, or become sick or die; would there be therefore any necessity that God should die, or suffer sickness, or become a slave, simply because such things had been foretold? Must he die in order to prove his divinity? But the prophets never would utter predictions so wicked and impious. We need not therefore inquire whether a thing has been predicted or not, but whether the thing is honourable in itself, and worthy of God. In that which is evil and base, although it seemed that all men in the world had foretold it in a fit of madness, we must not believe. How then can the pious mind admit that those things which are said to have happened to him, could have happened to one who is God?" From this it is plain that Celsus feels the argument from prophecy to be very effective for convincing those to whom Christ is preached; but he seems to endeavour to overthrow it by an opposite probability, namely, "that the question is not whether the prophets uttered these predictions or not." But if he wished to reason justly and without evasion, he ought rather to have said, "We must show that these things were never predicted, or that those things which were predicted of Christ have never been fulfilled in him," and in that way he would have established the position which he holds. In that way it would have been made plain what those prophecies are which we apply to Jesus, and how Celsus could justify himself in asserting that that application was false. And we should thus have seen whether he fairly disproved all that we bring from the prophets in behalf of Jesus, or whether he himself is convicted of a shameless endeavour to resist the plainest truths by violent assertions.
Chapter XV.
After assuming that some things were foretold which are impossible in themselves, and inconsistent with the character of God, he says: "If these things were predicted of the Most High God, are we bound to believe them of God simply because they were predicted?" And thus he thinks he proves, that although the prophets may have foretold truly such things of the Son of God, yet it is impossible for us to believe in those prophecies declaring that He would do or suffer such things. To this our answer is that the supposition is absurd, for it combines two lines of reasoning which are opposed to each other, and therefore mutually destructive. This may be shown as follows. The one argument is: "If any true prophets of the Most High say that God will become a slave, or suffer sickness, or die, these things will come to God; for it is impossible that the prophets of the great God should utter lies." The other is: "If even true prophets of the Most High God say that these same things shall come to pass, seeing that these things foretold are by the nature of things impossible, the prophecies are not true, and therefore those things which have been foretold will not happen to God." When, then, we find two processes of reasoning in both of which the major premiss is the same, leading to two contradictory conclusions, we use the form of argument called "the theorem of two propositions," [4700] to prove that the major premiss is false, which in the case before us is this, "that the prophets have foretold that the great God should become a slave, suffer sickness, or die." We conclude, then, that the prophets never foretold such things; and the argument is formally expressed as follows: 1st, Of two things, if the first is true, the second is true; 2d, if the first is [4701] true, the second is not true, therefore the first is not true. The concrete example which the Stoics give to illustrate this form of argument is the following: 1st, If you know that you are dead, you are dead; 2d, if you know that you are dead, you are not dead. And the conclusion is--"you do not know that you are dead." These propositions are worked out as follows: If you know that you are dead, that which you know is certain; therefore you are dead. Again, if you know that you are dead, your death is an object of knowledge; but as the dead know nothing, your knowing this proves that you are not dead. Accordingly, by joining the two arguments together, you arrive at the conclusion--"you do not know that you are dead." Now the hypothesis of Celsus which we have given above is much of the same kind.
