Answer:
The Weakening of the Catholic Church By the Late Middle Ages, the Catholic Church was weakened by corruption, political struggles, and humanist ideas. Many Catholics were dismayed by worldliness and immorality in the Church, including the sale of indulgences and the practice of simony. The Church did not lose power because of the Scientific Revolution. It lost power because of a concurrent movement called the Protestant Reformation. The Protestant Reformation, which was begun by Martin Luther, resulted in a large portion of Europe's population leaving the Catholic Church. Conflicts between the papacy and the monarchy over political matters resulted in people losing faith in the Church. Events like the Babylonian Captivity and the Great Schism further weakened the Church's influence over the people. Aside from that, people were disgusted at the actions of the corrupt church officials.
