" How much less, then, is the disorder to be tolerated that arises when a Christian leaves his office and takes upon him a temporal office, or when a bishop or pastor leaves his office and takes upon him the office of a prince or judge; or, on the other hand, when a prince takes up the office of a bishop and lets his princely office go? Even today this shameful disorder rages and rules in the whole papacy, contrary to their own canons and laws. "

― Martin Luther , On War Against the Turk
