You are of your father the devil, and the desires of your father you will do. He was a murderer from the beginning, and he stood not in the truth; because truth is not in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father thereof.
Augustine of Hippo
(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.
