Isaias 1:3

And all the Jews even now teach that the nameless God spake to Moses; whence the Spirit of prophecy, accusing them by Isaiah the prophet mentioned above, said “The ox knoweth his owner, and the ass his master’s crib; but Israel doth not know Me, and My people do not understand.” And Jesus the Christ, because the Jews knew not what the Father was, and what the Son, in like manner accused them; and Himself said, “No one knoweth the Father, but the Son; nor the Son, but the Father, and they to whom the Son revealeth Him.” Now the Word of God is His Son, as we have before said. …

1. I judge it necessary to add to these details also what, by garbling passages of Scripture, they try to persuade us concerning their Propator, who was unknown to all before the coming of Christ. Their object in this is to show that our Lord announced another Father than the Maker of this universe, whom, as we said before, they impiously declare to have been the fruit of a defect. For instance, when the prophet Isaiah says, “But Israel hath not known Me, and My people have not understood Me,” they pervert his words to mean ignorance of the invisible Bythus. And that which is spoken by Hosea, “There is no truth in them, nor the knowledge of God,” they strive to give the same reference. And, “There is none that understandeth, or that seeketh after God: they have all gone out of the way, they are together become unprofitable,” they maintain to be said concerning ignorance of Bythus. …

Thus dogs that have strayed, track out their master by the scent; and horses that have thrown their riders, come to their master’s call if he but whistle. “The ox,” it is said, “knoweth his owner, and the ass his master’s crib; but Israel hath not known Me.” What, then, of the Lord? He remembers not our ill desert; He still pities, He still urges us to repentance.

Complaint is censure of those who are regarded as despising or neglecting. He employs this form when He says by Esaias: “Hear, O heaven; and give ear, O earth: for the Lord hath spoken, I have begotten and brought up children, but they have disregarded Me. The ox knoweth his owner, and the ass his master’s crib: but Israel hath not known Me.” For how shall we not regard it fearful, if he that knows God, shall not recognise the Lord; but while the ox and the ass, stupid and foolish animals, will know him who feeds them, Israel is found to be more irrational than these? And having, by Jeremiah, complained against the people on many grounds, He adds: “And they have forsaken Me, saith the Lord .”

They say, too, that Here delights in the lily, and Artemis in the myrtle. For if the flowers were made especially for man, and senseless people have taken them not for their own proper and grateful use, but have abused them to the thankless service of demons, we must keep from them for conscience sake. The crown is the symbol of untroubled tranquillity. For this reason they crown the dead, and idols, too, on the same account, by this fact giving testimony to their being dead. For revellers do not without crowns celebrate their orgies; and when once they are encircled with flowers, at last they are inflamed excessively. We must have no communion with demons. Nor must we crown the living image of God after the manner of dead idols. For the fair crown of amaranth is laid up for those who have lived well. This flower the earth is not able to bear; heaven alone is competent to produce it. …

And when, again, it is said in the ode, “For He hath triumphed gloriously: the horse and his rider hath He cast into the sea;” the many-limbed and brutal affection, lust, with the rider mounted, who gives the reins to pleasures, “He has cast into the sea,” throwing them away into the disorders of the world. Thus also Plato, in his book On the Soul , says that the charioteer and the horse that ran off, the irrational part, which is divided in two, into anger and concupiscence, fall down; and so the myth intimates that it was through the licentiousness of the steeds that Phaëthon was thrown out. …

Since, therefore, there clearly exist these two characteristics in the Jewish prophetic literature, let the reader remember, whenever we adduce any evidence therefrom, that, by mutual consent, the point of discussion is not the form of the scripture, but the subject it is called in to prove. When, therefore, our heretics in their phrenzy presumed to say that that Christ was come who had never been fore-announced, it followed that, on their assumption, that Christ had not yet appeared who had always been predicted; and thus they are obliged to make common cause with Jewish error, and construct their arguments with its assistance, on the pretence that the Jews were themselves quite certain that it was some other who came: so they not only rejected Him as a stranger, but slew Him as an enemy, although they would without doubt have acknowledged Him, and with all religious devotion followed H …

Now, since you join the Jews in denying that their Christ has come, recollect also what is that end which they were predicted as about to bring on themselves after the time of Christ, for the impiety wherewith they both rejected and slew Him. For it began to come to pass from that day, when, according to Isaiah, “a man threw away his idols of gold and of silver, which they made into useless and hurtful objects of worship;” in other words, from the time when he threw away his idols after the truth had been made clear by Christ. Consider whether what follows in the prophet has not received its fulfilment: “The Lord of hosts hath taken away from Judah and from Jerusalem, amongst other things, both the prophet and the wise artificer;” that is, His Holy Spirit, who builds the church, which is indeed the temple, and household and city of God. …

Who shall be invoked as the Lord of heaven, that does not first show Himself to have been the maker thereof? For He says, “I thank thee, (O Father) and own Thee, Lord of heaven, because those things which had been hidden from the wise and prudent, Thou has revealed unto babes.” What things are these? And whose? And by whom hidden? And by whom revealed? If it was by Marcion’s god that they were hidden and revealed, it was an extremely iniquitous proceeding; for nothing at all had he ever produced in which anything could have been hidden, no prophecies, no parables, no visions, no evidences of things, or words, or names, obscured by allegories and figures, or cloudy enigmas, but he had concealed the greatness even of himself, which he was with all his might revealing by his Christ. …

If the Father “sent His Son in the likeness of sinful flesh,” it must not therefore be said that the flesh which He seemed to have was but a phantom. For he in a previous verse ascribed sin to the flesh, and made it out to be “the law of sin dwelling in his members,” and “warring against the law of the mind.” On this account, therefore, (does he mean to say that) the Son was sent in the likeness of sinful flesh, that He might redeem this sinful flesh by a like substance, even a fleshly one, which bare a resemblance to sinful flesh, although it was itself free from sin. Now this will be the very perfection of divine power to effect the salvation (of man) in a nature like his own. …

10. Nor ought we, beloved brethren, only to observe and understand that we should call Him Father who is in heaven; but we add to it, and say our Father, that is, the Father of those who believe, of those who, being sanctified by Him, and restored by the nativity of spiritual grace, have begun to be sons of God. A word this, moreover, which rebukes and condemns the Jews, who not only unbelievingly despised Christ, who had been announced to them by the prophets, and sent first to them, but also cruelly put Him to death; and these cannot now call God their Father, since the Lord confounds and confutes them, saying, “Ye are born of your father the devil, and the lusts of your father ye will do. …

In Isaiah: “Hear, O heaven, and give ear, O earth: for the Lord hath spoken; I have begotten and brought up children, but they have rejected me. The ox knoweth his owner, and the ass his master’s crib: but Israel hath not known me, and my people hath not perceived me. Ah sinful nation, a people filled with sins, a wicked seed, corrupting children: ye have forsaken the Lord, and have sent that Holy One of Israel into anger.” In the same also the Lord says: “Go and tell this people, Ye shall hear with the ear, and shall not understand; and seeing, ye shall see, and shall not perceive. …
