Since I see thee, most excellent Diognetus, exceedingly desirous to learn the mode of worshipping God prevalent among the Christians, and inquiring very carefully and earnestly concerning them, what God they trust in, and what form of religion they observe, so as all to look down upon the world itself, and despise death, while they neither esteem those to be gods that are reckoned such by the Greeks, nor hold to the superstition of the Jews; and what is the affection which they cherish among themselves; and why, in fine, this new kind or practice [of piety] has only now entered into the world, and not long ago; I cordially welcome this thy desire, and I implore God, who enables us both to speak and to hear, to grant to me so to speak, that, above all, I may hear you have been edified, and to you so to hear, that I who speak may have no cause of regret for having done so.
Come, then, after you have freed yourself from all prejudices possessing your mind, and laid aside what you have been accustomed to, as something apt to deceive you, and being made, as if from the beginning, a new man, inasmuch as, according to your own confession, you are to be the hearer of a new [system of] doctrine; come and contemplate, not with your eyes only, but with your understanding, the substance and the form of those whom ye declare and deem to be gods. Is not one of them a stone similar to that on which we tread? Is not a second brass, in no way superior to those vessels which are constructed for our ordinary use? Is not a third wood, and that already rotten? Is not a fourth silver, which needs a man to watch it, lest it be stolen? Is not a fifth iron, consumed by rust? Is not a sixth earthenware, in no degree more valuable than that which is formed for the humblest purposes? Are not all these of corruptible matter? Are they not fabricated by means of iron and fire? Did not the sculptor fashion one of them, the brazier a second, the silversmith a third, and the potter a fourth? Was not every one of them, before they were formed by the arts of these [workmen] into the shape of these [gods], each in its own way subject to change? Would not those things which are now vessels, formed of the same materials, become like to such, if they met with the same artificers? Might not these, which are now worshipped by you, again be made by men vessels similar to others? Are they not all deaf? Are they not blind? Are they not without life? Are they not destitute of feeling? Are they not incapable of motion? Are they not all liable to rot? Are they not all corruptible? These things ye call gods; these ye serve; these ye worship; and ye become altogether like to them. For this reason ye hate the Christians, because they do not deem these to be gods. But do not ye yourselves, who now think and suppose [such to be gods], much more cast contempt upon them than they [the Christians do]? Do ye not much more mock and insult them, when ye worship those that are made of stone and earthenware, without appointing any persons to guard them; but those made of silver and gold ye shut up by night, and appoint watchers to look after them by day, lest they be stolen? And by those gifts which ye mean to present to them, do ye not, if they are possessed of sense, rather punish [than honour] them? But if, on the other hand, they are destitute of sense, ye convict them of this fact, while ye worship them with blood and the smoke of sacrifices. Let any one of you suffer such indignities! Let any one of you endure to have such things done to himself! But not a single human being will, unless compelled to it, endure such treatment, since he is endowed with sense and reason. A stone, however, readily bears it, seeing it is insensible. Certainly you do not show [by your conduct] that he [your God] is possessed of sense. And as to the fact that Christians are not accustomed to serve such gods, I might easily find many other things to say; but if even what has been said does not seem to any one sufficient, I deem it idle to say anything further.
And next, I imagine that you are most desirous of hearing something on this point, that the Christians do not observe the same forms of divine worship as do the Jews. The Jews, then, if they abstain from the kind of service above described, and deem it proper to worship one God as being Lord of all, [are right]; but if they offer Him worship in the way which we have described, they greatly err. For while the Gentiles, by offering such things to those that are destitute of sense and hearing, furnish an example of madness; they, on the other hand by thinking to offer these things to God as if He needed them, might justly reckon it rather an act of folly than of divine worship. For He that made heaven and earth, and all that is therein, and gives to us all the things of which we stand in need, certainly requires none of those things which He Himself bestows on such as think of furnishing them to Him. But those who imagine that, by means of blood, and the smoke of sacrifices and burnt-offerings, they offer sacrifices [acceptable] to Him, and that by such honours they show Him respect, —these, by supposing that they can give anything to Him who stands in need of nothing, appear to me in no respect to differ from those who studiously confer the same honour on things destitute of sense, and which therefore are unable to enjoy such honours.
