CatholicG33k Historical Highlight

The Pope Who Defended the Jesuits

When Carlo della Torre di Rezzonico became Pope Clement XIII, Enlightenment governments across Europe increasingly sought to limit the Church’s influence over education, missionary work, and public life. Their greatest target was the Society of Jesus, whose schools, universities, and worldwide missions had become central to Catholic renewal since the Council of Trent. Despite intense pressure from powerful monarchs, Clement refused to condemn the Jesuits unjustly. Instead, through Apostolicum Pascendi Munus in AD 1765, he publicly praised their fidelity to the Church and defended their educational and missionary contributions. Although he died before the crisis reached its climax, his unwavering witness demonstrated that the Successor of St. Peter is called to protect the Church’s spiritual mission even when confronted by the demands of the world’s most powerful rulers.
