Well, lets look at the context in which Jesus is speaking. Jesus is talking to the unbelieving Jews who are about to stone him and accused him of being a demon. To which Jesus tells them that they don't understand because their father was the devil and a liar from the beginning. ( Jn 8:44) The beginning, I believe, is the beginning. Before man. Remember, Satan was a good angel. In the beginning. And he disobeyed God and was cast out of heaven, in the beginning. We have only to look at Genesis and the many things that happened "in the beginning."
Angels were created by and for the Son of God. (Colossians 1:16) They carry out God's orders and are attentive to his word. (Psalm 103: 20) They are his messengers of salvation. (Hebrews 1:14; CCC#331) Some angels began as good angels (Satan) but sinned. These angels cannot be pardoned because their choice against God is irrevocable the same as it is for humans who die. (CCC#393, 414). Thus, in the beginning, Lucifer and all that were with him were cast out of heaven. (St. Michael the Archangel, pray for us!)
The Late Holy Father said this:
When, by an act of his own free will, he rejected the truth that he knew about God, Satan became the cosmic "liar and the father of lies" (John 8:44). For this reason, he lives in radical and irreversible denial of God and seeks to impose on creation — on the other beings created in the image of God and in particular on people — his own tragic "lie about the good" that is God.
"God did not make death, and he does not delight in the death of the living. For he has created all things that they might exist ... God created man for incorruption, and made him in the image of his own eternity, but through the devil's envy death entered the world, and those who belong to his party experience it" (Wis 1:13-14; 2:23-24).
"The devil, however, since he is an apostate angel, is able, as he was in the beginning, to lead astray and to deceive the mind of man for the transgressing of God's commands. Little by little he can darken the hearts of those who would try to serve him, to the point that, forgetting the true God, they adore him as if he were God" (Against Heresies 5:24:3 [inter A.D. 180-199]).
and the website you linked us to Augustine, is not all in line with Catholic Church teachings. Just FYI and a precaution, unless of course your another denomination. And we had a discussion on the statement once, about how everything that God made is good, so where does that leave Satan? You can search it, it was a great thread and discussion.
hope that helps some.
