Which of Luther's teachings most influenced john Calvin?

John Calvin was significantly influenced by Martin Luther's emphasis on the doctrine of justification by faith alone. This teaching underscored the belief that salvation comes through faith rather than works, shaping Calvin's own theological framework. Additionally, Luther's views on the authority of Scripture over church tradition resonated with Calvin, leading him to develop his own ideas about predestination and the sovereignty of God. Together, these principles laid the groundwork for Calvin's distinct Reformed theology.
