Final answer:
Calvin and Luther had different views on the role of Christians in society. Luther believed in faith alone for salvation, while Calvin emphasized the idea of predestination. Both emphasized personal piety and the reading of scripture.
Step-by-step explanation:
Calvin and Luther both had views on the role of Christians in society that differed from the official teachings of the Roman Catholic Church. Luther believed that faith alone was sufficient for salvation and that humans were unable to work toward their own redemption. Calvin, on the other hand, emphasized the idea of predestination and the belief that God had predetermined salvation for some people.
Both Calvin and Luther believed in the importance of personal piety and the reading of scripture, but Calvinism, unlike Lutheranism, emphasized human powerlessness before God and stressed the idea that only the elect were destined for salvation.
