Why did Erasmus say humanists should study Christianity?

Erasmus believed that humanists should study Christianity to foster a deeper understanding of moral values and ethical living, which are central to both humanist and Christian thought. He argued that a thorough knowledge of the Scriptures would enhance one's ability to engage critically with texts and ideas, promoting a more profound spiritual and intellectual life. By integrating classical Humanism with Christian teachings, Erasmus sought to reform the Church and encourage a return to genuine piety, emphasizing the importance of inner faith over ritualistic practices.
