4 Types of Pride: first is when someone attributes to himself the good which he has; the second, when he believes that the good is given by God, and yet for his own merits; the third, when he boasts that he has what he does not have; the fourth, when he has contempt for all others and wishes to seem unique.Moralia, bk 2, c6, n13
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
Original corruption, by which we are dead to God and to godliness from the birth, and made willing slaves to the performance of all actual sins, until the Son of God makes us free. It consists in a propensity and inclination of the heart to sin, and an averseness to holiness.The Gospel Mystery of Sanctification: Growing in Holiness by Living in Union with Christ
Original sin is not the sin that Adam and Eve committed. It is the result of that first sin. Original Sin has reference to our sinful condition, our sinful bent, our sinful inclination from which actual sin flows.The Great Rescue, 17-18
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
