513. Whether contrition is the same as repentance or not can be decided from the description of repentance in what follows, namely, that it cannot exist unless a person not only in general terms but also in detail knows that he is a sinner. No one can know this unless he examines himself and sees the sins in himself, and for that reason condemns himself. The contrition, however, which is preached about as being necessary in order to acquire faith, has nothing in common with these actions, for it is merely thinking, and so confession, that one is by birth involved in Adam's sin and prone to the evils that gush forth from that source; as a result, one is subject to the wrath of God, and so deservedly damned and doomed to everlasting death. It is plain from this that contrition of this sort is not repentance.
