What is Protestantism? The best description is still that of Ernst Troeltsch, who early in the twentieth century called Protestantism a “modification of Catholicism” in which Catholic problems remain, but different solutions are given. The four questions that Protestantism answered in a new way are: (1) How is a person saved? (2) Where does religious authority lie? (3) What is the church? And (4) what is the essence of Christian living?
