even infants bringing their condemnation with them from their mother's womb, suffer not for another's, but for their own defect. For although they have not yet produced the fruits of their own unrighteousness, they have the seem implanted in them. No, their whole nature is, as it were, a seed-bed of sin, and therefore cannot but be odious and abominable to God.Institutes, Book 2 Chapter 1
the sin of the first man harmed not only him, but the whole human race, because from it we received condemnation and fault together.Hypognosticon, bk2 c4 n4
some heretics, who are called Pelagians, said that the sin of the first transgression passed into other men not by propagation, but by imitationDe Peccatorum b1 c9 m9-10
Here Peter Lombard has displayed gross ignorance (Lombard, lib. 2 dist. 31). When investigating the seat of corruption, he says it is in the flesh (as Paul declares), not properly, indeed, but as being more apparent in the flesh. As if Paul had meant that only a part of the soul, and not the whole nature, was opposed to supernatural grace.Institutes, Book 2 Chapter 1
It was because we rejected the doctrine of original sin that we on the Left were always being disappointed; disappointed by the refusal of people to be reasonable... by the behavior of nations and politicians... above all, by the recurrent fact of war.
The prohibition to touch the tree of the knowledge of good and evil was a trial of obedience, that Adam, by observing it, might prove his willing submission to the command of God.Institutes Book 2 Chapter 1
Many Modernists at present do not hesitate to say that the doctrine of Rousseau respecting the inherent goodness of man has proved to be one of the most pernicious teachings of the Enlightenment, and now call for a greater measure of realism in the recognition of sin.Systematic Theology, 227
Some may for a time dream of the essential goodness of man and speak indulgently of those separate words and actions that do not measure up to the ethical standards of good society as mere foibles and weaknesses, for which man is not responsible, and which readily yield to corrective measures; but as time goes on, and all measures of external reform fail, and the suppression of one evil merely serves to release another, such persons are inevitably disillusioned. They become conscious of the fact that they have merely been fighting the symptoms of some deep-seated malady, and that they are confronted, not merely with the problem of sins, that is, of separate sinful deeds, but with the much greater and deeper problem of sin, of an evil that is inherent in human nature.Systematic Theology, 227
We have all been born in sin, and, conceived from the pleasure of the flesh, we have all contracted the original fault in ourselves; so it is that we embroil ourselves in sin also by our own will.On Exod 13, 13
