The Apology of the Augsburg Confession

Excerpt-For some contend that original sin is not a depravity or corruption in the nature of man, but only servitude, or a condition of mortality [not an innate evil nature, but only a blemish or imposed load, or burden], which those propagated from Adam bear because of the guilt of another [namely, Adam's sin], and without any depravity of their own. Besides, they add that no one is condemned to eternal death on account of original sin, just as those who are born of a bond-woman are slaves, and bear this condition without any natural blemish, but because of the calamity of their mother [while, of themselves, they are born without fault, like other men: thus original sin is not an innate evil but a defect and burden which we bear since Adam, but we are not on that account personally in sin and inherited disgrace]. To show that this impious opinion is displeasing to us, we made mention of "concupiscence," and, with the best intention, have termed and explained it as "diseases," that "the nature of men is born corrupt and full of faults" [not a part of man, but the entire person with its entire nature is born in sin as with a hereditary disease].
