Original sin may be defined as the hereditary corruption and depravity of our nature. This reaches every part of the soul, makes us abhorrent to God’s wrath and produces in us what Scripture calls works of the flesh.
John Calvin
Certain new theologians dispute original sin, which is the only part of Christian theology which can really be proved.
G.K. Chesterton
The glad news brought by the gospel was the good news of original sin.
Francis of Assisi
Original sin is the only rational solution of the undeniable fact of the deep, universal and early manifested sinfulness of men in all ages, of every class, and in every part of the world.
Charles Hodge
We repudiated all versions of the doctrine of original sin, of there being instances of irrational springs of wickedness in most men.
John Maynard Keynes
Original sin is in us, like the beard. We are shaved today and look clean, and have a smooth chin; tomorrow our beard has grown again, nor does it cease growing while we remain on earth.
Martin Luther
Everything is good when it leaves the hands of the Creator; everything degenerates in the hands of men.
Jean-Jacques Rousseau
