J.V. Fesko in his article on Calvin on Justification and Recent Misinterpretations of His View writes, “It is the contention of this essay that recent interpretation of Calvin that emphasizes the believer’s union with Christ at the expense of the imputed righteousness of Christ, and those who claim that there is a great divergence between Calvin and Luther and their respective explanations of justification, are incorrect. Rather, central to Calvin’s doctrine of justification is the imputed righteousness of Christ. There is also consonance between Luther and Calvin on justification, especially regarding the relationship between justification and sanctification, or works and the third use of the law.” Read the full article here.
