The church has long spoken of these things:
418 AD - Council of Carthage (Early Christian Church)
This council's position on original sin was, even "new-born children... have in them... original sin inherited from Adam".
529 AD - Council of Orange (Early Christian Church)
"... it is the whole man, that is, both body and soul, that was 'changed for the worse' through the offense of Adam's sin..."
"...also that sin, which is the death of the soul, passed through one man to the whole human race..."
1530 - Augsburg Confession (Lutheran Church)
"...since the fall of Adam all men begotten in the natural way are born with sin, ...and that this disease, or vice of origin, is truly sin, even now condemning and bringing eternal death upon those not born again..."
1537 - The Smalcald Articles (Lutheran Church)
"... sin originated [and entered the world] from one man Adam, by whose disobedience all men were made sinners, [and] subject to death and the devil. This is called original or capital sin."
"This hereditary sin is so deep and [horrible] a corruption of nature that no reason can understand it, but it must be [learned and] believed from the revelation of Scriptures..."
1618 - The Canons of Dordt (Reformed Church)
"Man brought forth children of the same nature as himself after the fall. That is to say, being corrupt he brought forth corrupt children. The corruption spread, by God's just judgment, from Adam to all his descendants – except for Christ alone – not by way of imitation (as in former times the Pelagians would have it) but by way of the propagation of his perverted nature."
"Therefore, all people are conceived in sin and are born children of wrath, unfit for any saving good, inclined to evil, dead in their sins, and slaves to sin;..."
"... original sin in itself is enough to condemn the whole human race..."
"... unregenerate man is... totally dead in his sins... [and is] deprived of all capacity for spiritual good..."
1618 - Belgic Confession (Reformed Church)
"... by the disobedience of Adam original sin has been spread through the whole human race."
"It is a corruption of all nature-- an inherited depravity which even infects small infants in their mother's womb, and the root which produces in man every sort of sin. It is therefore so vile and enormous in God's sight that it is enough to condemn the human race,..."
1644 - First London Baptist Confession of Faith (Baptist Church)
"... first Eve, then Adam being seduced did wittingly and willingly fall into disobedience and transgression of the Commandment of their great Creator, for the which death came upon all, and reigned over all, so that all since the Fall are conceived in sin, and brought forth in iniquity, and so by nature children of wrath, and servants of sin, subjects of death,..."
1646 - The Westminster Confession of Faith (Presbyterian Church)
"Our first parents, being seduced by the subtilty and temptations of Satan, sinned, in eating the forbidden fruit."
"By this sin they fell from their original righteousness and communion, with God, and so became dead in sin, and wholly defiled in all the parts and faculties of soul and body."
"They being the root of all mankind, the guilt of this sin was imputed; and the same death in sin, and corrupted nature, conveyed to all their posterity descending from them by ordinary generation."
"Every sin, both original and actual,... bring guilt upon the sinner, whereby he is bound over to the wrath of God, and curse of the law, and so made subject to death..."
1689 - Second London Baptist Confession of Faith (Baptist Church)
"Our first parents, by this sin, fell from their original righteousness and communion with God, and we in them whereby death came upon all: all becoming dead in sin, and wholly defiled in all the faculties and parts of soul and body."
"... and corrupted nature conveyed, to all their posterity descending from them by ordinary generation, being now conceived in sin, and by nature children of wrath, the servants of sin, the subjects of death,..."
