Chapter 1
It is not, my reverend Ambrosius, because we seek after many words — a thing which is forbidden, and in the indulgence of which it is impossible to avoid sin — that we now begin the fifth book of our reply to the treatise of Celsus, but with the endeavour, so far as may be within our power, to leave none of his statements without examination, and especially those in which it might appear to some that he had skilfully assailed us and the Jews. If it were possible, indeed, for me to enter along with my words into the conscience of every one without exception who peruses this work, and to extract each dart which wounds him who is not completely protected with the whole armour of God, and apply a rational medicine to cure the wound inflicted by Celsus, which prevents those who listen to his words from remaining sound in the faith, I would do so. But since it is the work of God alone, in conformity with His own Spirit, and along with that of Christ, to take up His abode invisibly in those persons whom He judges worthy of being visited; so, on the other hand, is our object to try, by means of arguments and treatises, to confirm men in their faith, and to earn the name of workmen needing not to be ashamed, rightly dividing the word of truth. And there is one thing above all which it appears to us we ought to do, if we would discharge faithfully the task enjoined upon us by you, and that is to overturn to the best of our ability the confident assertions of Celsus. Let us then quote such assertions of his as follow those which we have already refuted (the reader must decide whether we have done so successfully or not), and let us reply to them. And may God grant that we approach not our subject with our understanding and reason empty and devoid of divine inspiration, that the faith of those whom we wish to aid may not depend upon human wisdom, but that, receiving the mind of Christ from His Father, who alone can bestow it, and being strengthened by participating in the word of God, we may pull down every high thing that exalts itself against the knowledge of God, and the imagination of Celsus, who exalts himself against us, and against Jesus, and also against Moses and the prophets, in order that He who gave the word to those who published it with great power may supply us also, and bestow upon us great power, so that faith in the word and power of God may be implanted in the minds of all who will peruse our work.
Chapter 2
We have now, then, to refute that statement of his which runs as follows: O Jews and Christians, no God or son of a God either came or will come down (to earth). But if you mean that certain angels did so, then what do you call them? Are they gods, or some other race of beings? Some other race of beings (doubtless), and in all probability demons. Now as Celsus here is guilty of repeating himself (for in the preceding pages such assertions have been frequently advanced by him), it is unnecessary to discuss the matter at greater length, seeing what we have already said upon this point may suffice. We shall mention, however, a few considerations out of a greater number, such as we deem in harmony with our former arguments, but which have not altogether the same bearing as they, and by which we shall show that in asserting generally that no God, or son of God, ever descended (among men), he overturns not only the opinions entertained by the majority of mankind regarding the manifestation of Deity, but also what was formerly admitted by himself. For if the general statement, that no God or son of God has come down or will come down, be truly maintained by Celsus, it is manifest that we have here overthrown the belief in the existence of gods upon the earth who had descended from heaven either to predict the future to mankind or to heal them by means of divine responses; and neither the Pythian Apollo, nor Æsculapius, nor any other among those supposed to have done so, would be a god descended from heaven. He might, indeed, either be a god who had obtained as his lot (the obligation) to dwell on earth for ever, and be thus a fugitive, as it were, from the abode of the gods, or he might be one who had no power to share in the society of the gods in heaven; or else Apollo, and Æsculapius, and those others who are believed to perform acts on earth, would not be gods, but only certain demons, much inferior to those wise men among mankind, who on account of their virtue ascend to the vault of heaven.
Chapter 3
But observe how, in his desire to subvert our opinions, he who never acknowledged himself throughout his whole treatise to be an Epicurean, is convicted of being a deserter to that sect. And now is the time for you, (reader), who peruse the works of Celsus, and give your assent to what has been advanced, either to overturn the belief in a God who visits the human race, and exercises a providence over each individual man, or to grant this, and prove the falsity of the assertions of Celsus. If you, then, wholly annihilate providence, you will falsify those assertions of his in which he grants the existence of God and a providence, in order that you may maintain the truth of your own position; but if, on the other hand, you still admit the existence of providence, because you do not assent to the dictum of Celsus, that neither has a God nor the son of a God come down nor is to come down to mankind, why not rather carefully ascertain from the statements made regarding Jesus, and the prophecies uttered concerning Him, who it is that we are to consider as having come down to the human race as God, and the Son of God?— whether that Jesus who said and ministered so much, or those who under pretence of oracles and divinations, do not reform the morals of their worshippers, but who have besides apostatized from the pure and holy worship and honour due to the Maker of all things, and who tear away the souls of those who give heed to them from the one only visible and true God, under a pretence of paying honour to a multitude of deities?
