The chart below provides a quick-reference guide to the major differences between Catholic and Protestant theology, especially at the time of the Reformation. As is always true with charts and other summaries, the information is oversimplified for the sake of brevity and should be used alongside more complete explanations.
The Protestant positions listed here are based primarily on the historical Lutheran and Reformed perspectives. The beliefs listed for both Catholics and Protestants by no means represent those of all churches or individuals within that tradition.
