EOIC WRITES:
There is no such thing as original sin.
This just goes to show that there is nothing new under the sun. This is the same denial a fellow by the name of Pelagius was peddling back in St.Augustine's day. Pelagius, probably born in Britain around 354 denied Original Sin writing that Adam's sin was purely personal and it would be unjust for God to punish the human race for his transgression. Since all are born without sin, infant Baptism is useless, etc. He also taught on freedom of the will and that Divine grace, actual or sanctifying is unnecessary. The freedom would be destroyed if the will were inclined to evil becasue of another's sin or had to be strengthend by another's help. The Redemption doesn't give new life to the human race. Pelagianism rests on the idea that God is only a spectator in the events of human salvation.
St.Augustine was the champion of orthodoxy against the heresy of Pelagianism which was condemned at the Council of Carthage in 418, afterwards confirmed by the Pope and at the General Council of Ephesus in 431.
Original sin as sexual sin began life with the writings of Saint Augustine of Hippo, one of the most influential Christian writers and thinkers in the history of the Church. Augustine was not always a Christian. He was a convert from Manicheanism, and before his fascination with Dualism took hold he had been, by his own confession, a drunkard and a general debauchee, possessed by a rabid appetite for sex.
What he so eagerly enjoyed in his youth he was to deny to others in his later life, being tormented by guilt - or, as he put it, having repented of his 'sin'. Augustine is the principal originator of the doctrine of Original Sin as a sexually transmitted disease of the Spirit, a doctrine to be found in his greatest work 'The City of God'.
Of St. Aurelius Augustine, Bishop, theologian and Doctor of the Church...Nov. 13, 354 to Aug. 28, 430...No two spiritual experiences could be more opposed than those of St. Augustine and Pelagius.
Your description of Augustine in his early years is accurate...by the age of 16, he lived a life of sensual pleasure and for 12 years, he placed his intellectual hopes in the sect of Manichaeism and behind their myths.
According to the biography of his mother, St.Monica, she cried and prayed for his conversion day and night....and God must have listened to her....for we know that prayers work.
Manchiaeism proved disappointing to Augustine's searching quieries and so he moved to Milan where he was converted in part due to Bishop Ambrose's spritual guidance in the concept of God and man, his introduction with NeoPlatonism where he discovered man's personal responsibility for the evil they commit and his reading of St.Paul particularly his Epistles to the Galatians and Romans.
The experience of his conversion convinced him that there could be an efficacious grace necessary to break the habit and the slavery of sin. His mother lived to see her son baptized in 387 in Milan. Within one year he had begun 2 philosophical dialogues and his first treatise against the Manichees. Until 399, he struggled against the heresy of Manicheism until after engaging in public dialogue, his opponent, the Manicheism Felix was himself converted. St.Augustine refuted Manicheism and it was finally condemned at the Twelth General Council, the FOurth Council of the Lateran in 1215.
Following that, St.Augustine preached against the schismatic Donatists at Carthage and it was during a conference in 411 that he first met Pelagius. A Council at Carthage in 411 had condemned Celestius, a disciple of Pelagius and St.Augustine soon began his first anti-Pelagian work, De peccoatorum meritis et remissione. In 417, the Pope confirmed the excommunication of the two heretics, Pelagius and Celestius at the Synod at Milevas.
Fifteen years before the anti-Pelagian controversy, St.Augustine theology of grace was entirely developed and clear.
Augustine is the principal originator of the doctrine of Original Sin as a sexually transmitted disease of the Spirit, a doctrine to be found in his greatest work 'The City of God'.
I've researched until I'm blue in the face and can't find this particular reference of yours concerning transmission, but I have found this.
In his writings on grace that came shortly after his conversion, St. Augustine's philosophy professed a creation that makes God not only the source of man's being but also of the conversion that makes man free. This doubling of the divine gratuity in Creation and in man's formation is shown again in the accomplishment of a good will. In directly opposing Pelagius, St.Augustine made this more explicit by stating that God also gives man capability, desire and action and even final perseverance.
This theology is governed by St.Augustine's idea of the primacy of grace and of his personal experience of the wound caused by sin. He says the will exists in a state of ignorance and trouble it is enslaved by consupiscence (which is a consequence of Original Sin, the natural activity of instincts or passions not subordinate to reason which may lead often enough to actual sin).
St.Augustine's concept of freedom is astonishingly existential in in perception of inner disposition of the self and even more on its emphasis on the impossiblility of the will's remaining neutral. The will is always a love ie a pleasure and a pressure. Accordingly grace, far from being reduced to a light, moves the liberty within by a love and a pleasure. God does not order without giving man what he ordains.
There is no question that St.Augustine connected Original Sin in offspring and consupiscence in parents...and what is very important to realize is that this is his own theological theory concerning transmission....there are several more out there besides his.
So, in this sense, you are incorrect to say that "Augustine is the principal originator of the doctrine of Original Sin as a sexually transmitted disease of the Spirit, a doctrine to be found in his greatest work 'The City of God'". St. Augustine's theological ideas on the transmission are just that---his ideas and not what the Church dogmatically defined at Trent.
