Christians should regard and recognize the actual transgression of God's commandments as sin; but sin is also that horrible, dreadful hereditary sickness by which the entire human nature is corrupted. This should above all things be regarded and recognized as sin indeed. Yes, it is the chief sin, which is a root and fountainhead of all actual sins. Dr. Luther called it "nature sin" or "person sin." He says this to show that, even if a person would not think, speak, or do anything evil (which, however, is impossible in this life, since the fall of our first parents), his nature and person are nevertheless sinful. Before God they are thoroughly and utterly infected and corrupted by original sin, as by a spiritual leprosy. Because of this corruption and because of the fall of the first man, the human nature or person is accused or condemned by God's Law. So we are by nature the children of wrath, death, and damnation, unless we are delivered from them by Christ's merit. Article XIX of the Augsburg Confession teaches: God is not a creator, author, or cause of sin. By the instigation of the devil through one man, sin (which is the devil's work) has entered the world. Even today, in this corruption, God does not create and make sin in us. Original sin is multiplied from sinful seed, through fleshly conception and birth from father and mother. (paragraphs 5-7)
