Augsburg Confession

Article IV. Of Justification.

1 Also they teach that men cannot be justified before God by their own strength, merits, or works, but are freely justified for 2 Christ’s sake, through faith, when they believe that they are received into favor, and that their sins are forgiven for Christ’s sake, who, by His death, has made satisfaction for our sins. 3 This faith God imputes for righteousness in His sight. Rom. 3 and 4.
