To Florus 3.66

What, then, have we established? That the nonexistence of inherited sin is so certain that, even if you showed children punished for Adam’s sin, it would still be established that sins cannot be inborn and guilt cannot travel with reproductive seed, since you would admit that this does not happen in all reproduction. Consequently, even if vices were handed on to persons, they would not be mixed into conception.

But as it stands, you and I agree that a parent’s sin could not pass to children except through corruption and guilt in generation itself. Reason, examples, and the law agree that the condition of generation cannot possibly have been corrupted. Your own concession confirms this, for you say that no parents’ sins except those of two people pass to their children. It has therefore been established beyond defeat that the devil neither corrupted the first humans’ reproductive power nor made any sin capable of being born.
