All sin has its being and origin in the fact that man wants to be his own judge. And in wanting to be that, and thinking and acting accordingly, he and his whole world is in conflict with God. It is an unreconciled world, and therefore a suffering world, a world given up to destruction…not all men commit all sins, but all men commit this sin which is the essence and root of all other sins. There is not one who can boast that he does not commit it.
— Karl Barth, Dogmatics (IV.I.216f)
