Original sin

Overview
In Christian theology, original sin (Latin: peccatum originale) is the condition of sinfulness that all humans share, which they inherit from the Fall of Adam and Eve, involving the loss of original righteousness and the distortion of the Image of God. The biblical basis for the belief is generally found in Genesis 3 (the story of the expulsion of Adam and Eve from the Garden of Eden), and in texts such as Psalm 51:5 ("I was brought forth in iniquity, and in sin did my mother conceive me") and Romans 5:12–21 ("Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all people, because all sinned").
The specific doctrine of original sin was developed in the 2nd century struggle against Gnosticism by Irenaeus of Lyons, and was shaped significantly by Augustine of Hippo (354–430 AD), who was the first author to use the phrase "original sin" in his polemics against the Pelagians. Influenced by Augustine, the Councils of Carthage (411–418 AD) and Orange (529 AD) brought theological speculation about original sin into the official lexicon of the Church.
Protestant Reformers such as Martin Luther and John Calvin equated original sin with concupiscence (or 'hurtful desire'), affirming that it persisted even after baptism and completely destroyed freedom to do good, proposing that original sin involved a loss of free will except to sin. The Jansenist movement, which the Catholic Church declared heretical, also maintained that original sin destroyed freedom of will. Instead, the Catechism of the Catholic Church declares that "Baptism, by imparting the life of Christ's grace, erases original sin and turns a man back towards God, but the consequences for nature, weakened and inclined to evil, persist in man and summon him to spiritual battle", and the Council of Trent states that "whereas all men had lost their innocence in the prevarication of Adam [...] although free will, attenuated as it was in its powers, and bent down, was by no means extinguished in them."

And yet these miserable sophistical reasoners do not touch upon these deep corruptions even in word. But by taking this true view of original sin, it clearly demonstrates, according to the nature of correlative proofs, what original sin really was by its awful contrariety to that original righteousness. Thus it is evident that original sin is the essential and entire loss and deprivation and absence of original…

For the spirit it is a duty to be free, and to realise itself by its own act. Nature is for man only the starting-point which he has to transform. The theological doctrine of original sin is a profound truth; but modern enlightenment prefers to believe that man is naturally good, and that he acts right so long as he continues true to nature.

86. The first difficulty is how the soul could be infected with original sin, which is the root of actual sins, without injustice on God's part in exposing the soul thereto. This difficulty has given rise to three opinions on the origin of the soul itself. The first is that of the _pre-existence of human souls_ in another world or in another life, where they had sinned and on that account had been condemned to this…

For the first consists of two; the second is the complete death, which consists of all. For, as the whole earth consists of many lands, and the Church universal of many churches, so death universal consists of all deaths. The first consists of two, one of the body, and another of the soul. So that the first death is a death of the whole man, since the soul without God and without the body suffers punishment for a…

For, as Augustine says (QQ. Vet. et Nov. Test. qu. 19 [*Work of an anonymous author], among the supposititious works of St. Augustine): "God made man immortal as long as he did not sin; so that he might achieve for himself life or death." For man's body was indissoluble not by reason of any intrinsic vigor of immortality, but by reason of a supernatural force given by God to the soul, whereby it was enabled to…
