The Catholic Church was in crisis mode! Corruption, abuse, and indulgences had sparked the Reformation, and Protestantism was spreading like wildfire. In response, the Council of Trent gathered 25 top Catholic bishops and theologians to reform the Church from within. After 18 years of debates, they finally hammered out a definitive distinction between Roman Catholicism and Protestantism. This monumental gathering not only clarified Catholic doctrine but also laid the groundwork for the Counter-Reformation. The Council's decrees would shape Catholic teachings for centuries, sending ripples throughout European history!
