John Calvin's understanding of works-righteousness is more complex than is often recognized. While he denounces it in some instances, he affirms it in others. This study shows that Calvin affirms works-righteousness within the context where faith-righteousness is already established, and that he even teaches a form of justification by works. Calvin ascribes not only a positive role to good works in relation to divine acceptance, but also soteriological value to believers' good works. This study demonstrates such by exploring Calvin's theological anthropology, his understanding of divine-human activity, his teaching on the nature of good works, and his understanding of divine grace and benevolence. It also addresses current debates in Calvin scholarship by exploring topics such as union with Christ, the relation between justification and sanctification, the relation between good works and divine acceptance, the role of good works in the Christian life, and the content of good works.
