" And I extolled my sweetest word with a love as great as the hatred with which I had before hated the word “righteousness of God.” Thus that place in Paul was for me truly the gate to paradise. Later I read Augustine’s The Spirit and the Letter, where contrary to hope I found that he, too, interpreted God’s righteousness in a similar way, as the righteousness with which God clothes us when he justifies us. Although this was heretofore said imperfectly and he did not explain all things concerning imputation clearly, it nevertheless was pleasing that God’s righteousness with which we are justified was taught. Armed more fully with these thoughts, I began a second time to interpret the Psalter. And the work would have grown into a large commentary, if I had not again been compelled to leave the work begun, because Emperor Charles V in the following year convened the diet at Worms. "
