John 8:44

(tom. xx. 21.) Consider too; it was not one man only that he killed, but the whole human race, inasmuch as in Adam all die; so that he is truly called a murderer from the beginning. (tom. xx. 22.) There is only one way of standing in the truth; many and various of not standing in it. Some try to stand in the truth, but their feet tremble and shake so, they cannot. Others are not come to that pass, but are in danger of it, as we read in the Psalms, My feet were almost gone: (Ps. 72) others fall from it. Because the truth is not in him, is the reason why the devil did not stand in the truth. He imagined vain things, and deceived himself; wherein He was so far worse than others, in that, while others are deceived by him, he was the author of his own deception. But farther; does the truth is not in him, mean that he holds no true doctrine, and that every thing he thinks is false; or that he is not a member of Christ, who says, I am the truth? (c. 14:6) Now it is impossible that any rational being should think falsely on every subject and never be even ever so slightly right in opinion. The devil therefore may hold a true doctrine, by the mere law of his rational nature: and therefore his nature is not contrary to truth, i. e. does not consist of simple error and ignorance; otherwise he could never have known the truth. (tom. xx. 23.) Note however; this word, liar, is applied to man, as well as to the devil, who begat a lie, as we read in the Psalm, All men are liars. (Ps. 111) If a man is not a liar, he is not an ordinary man, but one of those, to whom it is said, I have said, Ye are Gods. (Ps. 81) When a man speaketh a lie, he speaketh of his own; but the Holy Spirit speaketh the word of truth and wisdom; as he said below, He shall receive of Mine, and shall show it unto you. (c. 16:15)

"Ye are of your father the devil, and the lusts of your father ye will do: he was a murderer from the beginning, and abode not in the truth: when he speaketh a lie, he speaketh of his own." He had driven them out of their relationship to Abraham, and when they dared greater things, He then addeth a blow, telling them that they not only are not Abraham's children, but that they are even children of the devil, and inflicting a wound which might counterbalance their shamelessness; nor doth He leave it unsupported, but establisheth it by proofs. "For," He saith, "to murder belongeth to the wickedness of the devil." And He said not merely, "ye do his works," but, "ye do his lusts," showing that both he and they hold to murder, and that envy was the cause. For the devil destroyed Adam, not because he had any charge against him, but only from envy. To this also He alludeth here.

"And abode not in the truth." That is, in the right life. For since they continually accused Him of not being from God, He telleth them that this also is from thence. For the devil first was the father of a lie, when he said, "In the day that ye eat thereof your eyes shall be opened," and he first used it. For men use a lie not as a thing proper, but alien to their nature, but he as proper.

Someone may object that the words of the Lord about the devil [here] … are to be understood as if he was not only a murderer from the beginning of the human race when human beings, whom he could kill by his deceit, were made; but also that he did not abide in the truth from the time of his own creation and was accordingly never blessed with the holy angels. Instead he refused to submit to his Creator and proudly exulted as if in a private lordship of his own. In this way he was deceived and deceiving.… But they do not notice that the Lord did not say, "The devil was naturally a stranger to the truth" but "The devil did not remain in the truth." By this, he meant us to understand that the devil had fallen from the truth in which, if he had remained, he would have become a partaker and would have remained in blessedness along with the holy angels.…They suppose [according to 1 John 3:8] that the devil was made with a sinful nature, but they misunderstand the passage; for if sin is natural, it is not sin at all. And how do they answer the prophetic proofs—either what Isaiah says when he represents the devil under the person of the king of Babylon, "How you are fallen, O Lucifer, son of the morning!" or what Ezekiel says, "You were in Eden, the garden of God …" where it is meant that he was at some point without sin? For a little after, it is still more explicitly said, "You were perfect in your ways." And if these passages cannot be interpreted properly in any other way, then we must understand by this passage also, "He did not remain in the truth," that he was once in the truth but did not remain in it. And from this passage, "The devil has sinned from the beginning," it is not that he sinned from the beginning of his created existence; rather, sin began in him, and he was the beginning of sin.

(Tr. xlii. 10) Here we must guard against the heresy of the Manichæans, who hold a certain original nature of evil, and a nation of darkness with princes at their head, whence the devil derives his existence. And thence they say our flesh is produced; and in this way interpret our Lord's speech, Ye are of your father the devil: viz. to mean that they were by nature evil, drawing their origin from the opposite seed of darkness. (Tr. xlii. 11) The Jews then were children of the devil by imitation, not by birth: And the lusts of your father ye will do, our Lord says. Ye are his children then, because ye have such lusts, not because ye are born of him: for ye seek to kill Me, a man that hath told you the truth: and he envied man, and killed him: he was a murderer from the beginning; i. e. of the first man on whom a murder could be committed: man could not be slain, before man was created. The devil did not go, girt with a sword, against man: he sowed an evil word, and slew him. Do not suppose therefore that you are not guilty of murder, when you suggest evil thoughts to your brother. The very reason why ye rage against the flesh, is that ye cannot assault the soul. (xi. de Civ. Dei, c. 13) But it will be objected perhaps, that if from the beginning of his existence, the devil stood not in the truth, he was never in a state of blessedness with the holy angels, refusing, as he did, to be subject to his Creator, and therefore false and deceitful; unwilling at the cost of pious subjection to hold that which by nature he was; and attempting in his pride and loftiness to simulate that which he was not. This opinion is not the same with that of the Manichæans, that the devil has his own peculiar nature, derived as it were from the opposite principle of evil. This foolish sect does not see that our Lord says not, Was alien from the truth, but Stood not in the truth, meaning, fell from the truth. And thus they interpret John, The devil sinneth from the beginning, (1 John 3:8) not seeing that if sin is natural, it is no sin. But what do the testimonies of the prophets reply? Isaiah, setting forth the devil under the figure of the prince of Babylon, says, How art thou fallen from heaven, O Lucifer, son of the morning! (Ezek. 28:13) Ezekiel says, Thou hast been in Eden, the garden of God. Which passages, as they cannot be interpreted in any other way, show that we must take the word, He stood not in the truth, to mean, that he was in truth, but did not remain in it; and the other, that the devil sinneth from the beginning, to mean, that he was a sinner not from the beginning of his creation, but from the beginning of sin. For sin began in him, and he was the beginning of sin. (xi. de Civ. Dei, c. xiv) Or when our Lord says, The truth is not in him, He intends it as an index: as if we had asked Him, how it appeared that the devil stood not in the truth; and He said, Because the truth is not in him. For it would be in him, if he stood in it. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it. (Tr. xlii. s. 12, 13) Some have thought from these words that the devil had a father, and asked who was the father of the devil. This is the error of the Manichæans. But our Lord calls the devil the father of a lie for this reason: Every one who lies is not the father of his own lie; for you may tell a lie, which you have received from another; in which case you have lied, but are not the father of the lie. But the lie wherewith, as with a serpent's bite, the devil slew man. had no source but himself: and therefore he is the father a lie, as God is the Father of the truth. (de Quæst. Nov. et Vet. Test. 2, 90) Or thus: The devil is not a singular, but a common name. In whomsoever the works of the devil are found, he is to be called the devil. It is the name of a work, not of a nature. Here then our Lord means by the father of the Jews, Cain; whom they wished to imitate, by killing the Saviour: for he it was who set the fi
