Q.18. What is sinful about man's sinful condition?
A.18. The sinfulness of that fallen condition is twofold. First, in what is commonly called original sin, there is the guilt of Adam's first sin with its lack of original righteousness and the corruption of his whole nature. Second are all the specific acts of disobedience that come from original sin.
