Why did Desiderius Erasmus focus on Latin, Greek, and Hebrew in education?

Desiderius Erasmus emphasized the study of Latin, Greek, and Hebrew because he believed that mastery of these ancient languages was essential for a true understanding of theology and the "philosophy of Christ".1

Erasmus argued that "ancient theology" required the ability to read and interpret original texts, such as the New Testament, rather than relying on the argumentative, "logic-chopping" methods of Scholasticism. By studying these languages, scholars could bypass later interpretations and engage directly with the Church Fathers and the Scriptures in their original context.1

His educational program, which prioritized these "humane letters" of classical and Christian antiquity, aimed to mold human nature and foster peaceful, social dispositions. For Erasmus, this linguistic foundation was not merely academic; it was a vital tool for reforming Christian society, as he believed that if the Gospel were truly understood and preached through these original sources, it would help spare people from the destructive conflicts of his time.12
