Isaias 1:10

He speaks moreover concerning our ears, how He hath circumcised both them and our heart. The Lord saith in the prophet, “In the hearing of the ear they obeyed me.” And again He saith, “By hearing, those shall hear who are afar off; they shall know what I have done.” And, “Be ye circumcised in your hearts, saith the Lord.” And again He says, “Hear, O Israel, for these things saith the Lord thy God.” And once more the Spirit of the Lord proclaims, “Who is he that wishes to live for ever? By hearing let him hear the voice of my servant.” And again He saith, “Hear, O heaven, and give ear, O earth, for God hath spoken.” These are in proof. …

3. For as, among men, those sons who disobey their fathers, being disinherited, are still their sons in the course of nature, but by law are disinherited, for they do not become the heirs of their natural parents; so in the same way is it with God, those who do not obey Him being disinherited by Him, have ceased to be His sons. Wherefore they cannot receive His inheritance: as David says, “Sinners are alienated from the womb; their anger is after the likeness of a serpent.” And therefore did the Lord term those whom He knew to be the offspring of men “a generation of vipers;” because after the manner of these animals they go about in subtilty, and injure others. For He said, “Beware of the leaven of the Pharisees and of the Sadducees.” Speaking of Herod, too, He says, “Go ye and tell that fox,” aiming at his wicked cunning and deceit. …

Well, then, Isaiah foretells that it behoves Him to be called Emmanuel; and that subsequently He is to take the power of Damascus and the spoils of Samaria, in opposition to the king of the Assyrians. “Now,” say they, “that (Christ) of yours, who is come, neither was called by that name, nor engaged in warfare.” But we, on the contrary, have thought they ought to be admonished to recall to mind the context of this passage as well. For subjoined is withal the interpretation of Emmanuel, “God with us”, in order that you may regard not the sound only of the name, but the sense too. For the Hebrew sound, which is Emmanuel, has an interpretation, which is, God with us. Inquire, then, whether this speech, “God with us” (which is Emmanuel), be commonly applied to Christ ever since Christ’s light has dawned, and I think you will not deny it. …

For besides the generally known fact, that the riches of the East, that is to say, its strength and resources, usually consist of gold and spices, it is certainly true of the Creator, that He makes gold the riches of the other nations also. Thus He says by Zechariah: “And Judah shall also fight at Jerusalem and shall gather together all the wealth of the nations round about, gold and silver.” Moreover, respecting that gift of gold, David also says: “And there shall be given to Him of the gold of Arabia;” and again: “The kings of Arabia and Saba shall offer to Him gifts.” For the East generally regarded the magi as kings; and Damascus was anciently deemed to belong to Arabia, before it was transferred to Syrophœnicia on the division of the Syrias (by Rome). …

I prefer elsewhere refuting the faults which the Marcionites find in the Creator. It is here enough that they are also found in Christ. Behold how unequal, inconsistent, and capricious he is! Teaching one thing and doing another, he enjoins “giving to every one that seeks;” and yet he himself refuses to give to those “who seek a sign.” For a vast age he hides his own light from men, and yet says that a candle must not be hidden, but affirms that it ought to be set upon a candlestick, that it may give light to all. He forbids cursing again , and cursing much more of course; and yet he heaps his woe upon the Pharisees and doctors of the law. Who so closely resembles my God as His own Christ? We have often already laid it down for certain, that He could not have been branded as the destroyer of the law if He had promulged another god. …

With swarm of sin? Does He, the truthful, bid,

In the Acts of the Apostles also, Stephen, in his other testimony, says, “Which of the prophets have not your fathers persecuted? And they have slain them which showed before of the coming of the Just One; of whom ye have been now the betrayers and murderers.” That Stephen speaks the truth, every one will admit who receives the Acts of the Apostles; but it is impossible to show from the extant books of the Old Testament how with any justice he throws the blame of having persecuted and slain the prophets on the fathers of those who believed not in Christ. …

What then shall we say? That he had not things present, and even now doing, in his view, but he knew the secrets of their mind, God having revealed this. Since then they were priding themselves on their forefathers, and this was like to prove the cause of their destruction, and was casting them into a state of carelessness, he cuts away the roots of their pride. For this cause Isaiah also calls them, “rulers of Sodom,” and “people of Gomorrah;”and another prophet saith, “Are ye not as children of the Ethiopians;”and all withdraw them from this way of thinking, bringing down their pride, which had caused them unnumbered evils.

And whence did the disciples know this? He had already told them, “He is Elias, which was for to come;”but here, that he hath come; and again, that “Elias cometh and will restore all things.” But be not thou troubled, nor imagine that His statement wavers, though at one time He said, “he will come,” at another, “he hath come.” For all these things are true. Since when He saith, “Elias indeed cometh, and will restore all things,” He means Elias himself, and the conversion of the Jews which is then to take place; but when He saith, “Which was for to come,” He calls John, Elias, with regard to the manner of his administration. Yea, and so the prophets used to call every one of their approved kings, David;and the Jews, “rulers of Sodom,”and “sons of Ethiopians;”because of their ways. For as the other shall be forerunner of the second advent, so was this of the first.

Shouldest thou then have gone all lengths in wickedness, yet say unto thyself, God is loving unto men and he desires our salvation: for “though your sins be as scarlet, I will whiten you as snow,” ( Is. i. 10 . Sept.) saith He; and unto the contrary habit I will change you. Let us not therefore give up in despair; for to fall is not so grievous, as to lie where we have fallen; nor to be wounded so dreadful, as after wounds to refuse healing. “For who shall boast that he has his heart chaste? or who shall say confidently that he is pure from sin?” ( Prov. xx. 9 . Sept.) These things I say not to make you more negligent, but to prevent your despairing.

Then is the charge against you the heavier, because the people believed, and ye believed not. They acted like men that knew the Law; how then are they accursed? It is ye that are accursed, who keep not the Law, not they, who obey the Law. Neither was it right, on the evidence of unbelievers, to slander one in whom they believed not, for this is an unjust mode of acting. For ye also believed not God, as Paul saith; “What if some did not believe? shall their unbelief make the faith of God of none effect? God forbid.” ( Rom. iii. 3, 4 .) For the Prophets ever rebuked them, saying, “Hear, ye rulers of Sodom”; and, “Thy rulers are disobedient” ( Isa. i. 10, 23 ); and again, “Is it not for you to know judgment?” ( Mic. iii. 1 .) And everywhere they attack them vehemently. What then? Shall one blame God for this? Away with the thought. This blame is theirs. …

But forasmuch as they pretend to charge me with cowardice, it is necessary that I should write somewhat concerning this, whereby it shall be proved that they are men of wicked minds, who have not read the sacred Scriptures: or if they have read them, that they do not believe the divine inspiration of the oracles they contain. For had they believed this, they would not dare to act contrary to them, nor imitate the malice of the Jews who slew the Lord. For God having given them a commandment, ‘Honour thy father and thy mother,’ and, ‘He that curseth father or mother, let him die the death;’ that people established a contrary law, changing the honour into dishonour, and alienating to other uses the money which was due from the children to their parents. …
