You are of your father the devil, and the lusts of your father you will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaks a lie, he speaks of his own: for he is a liar, and the father of it.

Augustine of Hippo
AD 430
Here we must guard against the heresy of the Manicheans, 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, You are of your father the devil: viz. to mean that they were by nature evil, drawing their origin from the opposite seed of darkness.
The Jews then were children of the devil by imitation, not by birth: And the lusts of your father you will do, our Lord says. You are his children then, because you have such lusts, not because you are born of him: for you seek to kill Me, a man that has 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 he 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 you rage against the flesh, is that you cannot assault the soul.
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 Manichaeans,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 sins from the beginning, 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 are you fallen from heaven, O Lucifer, son of the morning! Ezekiel says, You have 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 sins 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.
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.
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 Manichaeans. 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 ease 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 of a lie, as God is the Father of the truth.
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 awork, not of a nature. Here then our Lord means by the father of the Jews, Cain; whom they wished to imitate, by killing the Savior: for he it was who set the first example of murdering abrother. That he spoke a lie of his own, means that no one sins but by his own will. And inasmuch as Cain imitated the devil, and followed his works, the devil is said to be his father.
Apply this not to their nature, but to their faults. They both are from God and are not from God at the same time; their nature is from God, their fault is not from God. This was spoken too to those, who were not only faulty, by reason of sin, in the way in which all are: but who it was foreknown would never possess such faithas would free them from the bonds of sin.
